Glossary of Terms¶

Accountability Network¶

The group of people, such as cohort peers, a coach, or both, who continue checking in on a founder's progress against a public commitment after the course's final session.

Example: Priya's includes two cohort members she texts every Friday and a coach she meets with monthly.

Action¶

The third phase of the course cycle: doing the smallest real-world step that produces evidence, such as sending one message or asking one stranger to pay, rather than building a complete product first.

Example: Jordan borrowed a friend's car and groomed one neighbor's dog for $40 in their driveway.

See also: Launch, Minimum Testable Iteration

Activity Resource Needs¶

Any action or process that has to happen before a venture launches, as distinct from a physical item or a person, such as obtaining a permit or finishing a certification.

See also: Resource Needs

Advantage Articulation¶

Stating, specifically and with evidence, why a founder has a stronger claim to address a difficulty than an average rival would.

Example: Not "I care a lot about dogs," but "I've spent three years as a veterinary technician and already groom for six neighbors."

Advantage Block¶

The section of the CO.STARTERS Canvas that explains why this particular founder or venture is better positioned than others to deliver the proposed solution well.

Example: "Three years as a veterinary technician, with existing trust from local dog owners."

Advantage Sustainability¶

How long a venture's edge over rivals will actually hold once competitors notice it and try to copy it or respond to it.

See also: Competitive Advantage

Alternative Assessment¶

The evaluation of each mapped option against the confirmed customer difficulty, checking where it satisfies the customer and where it leaves them still wanting something.

See also: Competitive Analysis

Alternative Solution¶

Anything a target customer currently uses, does, or chooses instead of a founder's proposed offer to address their difficulty, a category far broader than similar companies.

Example: For Priya, these include takeout, frozen dinners, grandparents who cook, and simply skipping vegetables.

See also: Alternatives Block, Substitute Solution

Alternatives Block¶

The section of the CO.STARTERS Canvas that lists what target customers currently use or do instead of a venture's offer, including competitors, workarounds, and doing nothing at all.

Example: Jordan's entry lists salon groomers, backyard hose baths, and simply waiting longer between grooms.

Asking Not Selling¶

The core discipline of a discovery interview in which the founder only asks and listens, never describing, defending, or pitching the venture, since pitching turns honest data into polite agreement.

Example: When a parent asks "So what's your business?", Priya says she will share at the end and goes back to asking about the parent's week.

Assumption¶

A belief about a venture, whether about its customers, problem, solution, price, or channels, that the founder is treating as true but has not yet checked against real-world evidence.

Every block of the canvas starts out as one of these.

Example: "Parents will pay $25 per family meal" remains an untested belief until someone actually pays that amount.

See also: Customer Assumption, Assumption Testing, Weak Assumption

Assumption Dismantling¶

The structured process of identifying exactly which part of a weak or false belief was wrong, so the canvas can be corrected precisely rather than abandoned wholesale.

Example: Priya found that "parents want healthy meals" held up but "parents want to cook them" did not, so she kept the first part and changed the offer.

See also: Weak Assumption

Assumption Testing¶

Checking each individual claim on the canvas against the field evidence collected so far, one belief at a time, to see which survive, which are weak, and which are false.

Example: Priya lists ten canvas beliefs and marks each one "supported," "partly supported," or "contradicted" using her interview notes.

See also: Weak Assumption

B2B Customer¶

An organization, such as a company, school, or nonprofit, that purchases an offer for use in its operations, typically with more than one person involved in the buying decision.

Example: A daycare center that contracts with Priya to supply take-home dinners for its staff is this type of buyer.

Contrast with: B2C Customer

B2C Customer¶

An individual person or household that purchases an offer for personal use, usually making the buying decision alone or together with family members.

Contrast with: B2B Customer

Benefit Articulation¶

The discipline of stating the most important customer outcome plainly, in the customer's own words, rather than in internal company language.

Example: Priya replaces "optimized family meal logistics" with "dinner's ready before homework starts."

See also: Core Benefit

Benefit Block¶

The section of the CO.STARTERS Canvas that states the positive outcome a customer experiences from an offer, expressed in terms of their life rather than product features.

Example: "Get an hour of your evening back without feeding your kids takeout."

See also: Why Customer Wants It

Best Person To Solve It¶

The question of whether, among everyone who could plausibly attempt a venture, a particular founder has a genuinely stronger claim to succeed than an average rival would.

Example: A retired teacher asks whether twenty years in middle-school math classrooms make her a better choice than generic online tutoring.

Bootstrapped Funding¶

Financing a venture's startup needs with the founder's own resources, such as savings, existing equipment, and personal effort, rather than outside investment or loans.

Example: Jordan uses his own savings and a borrowed car instead of taking out a loan for a van.

See also: Startup Capital

Brand Voice¶

The consistent tone, vocabulary, and personality a venture maintains across all customer-facing language, so customers recognize the business wherever they encounter it.

See also: Customer-Facing Message

Break-Even Thinking¶

The discipline of calculating the point at which total income exactly covers total costs, so a founder knows how many sales are needed before a venture stops losing money each period.

Example: If Jordan's monthly fixed costs are $400 and each $40 groom uses $10 in supplies and gas, he needs about 14 grooms a month to cover costs.

See also: Fixed Costs, Variable Costs

Broad Market¶

The entire population of people who could conceivably ever use a type of solution, described in the widest possible terms, such as "dog owners" or "working parents."

It is a legitimate starting point but too wide to guide an early-stage offer.

Example: "Anyone who eats dinner" is the widest version of Priya's audience and tells her nothing about where to start.

Contrast with: Niche Market

Build-Measure-Learn¶

The repeating cycle, from Eric Ries's Lean Startup approach, of creating the smallest possible experiment, observing what real customers do in response, and using what is discovered to shape the next experiment.

Example: A tutor runs a trial session, counts how many parents rebook, and adjusts the session length before the next round.

Business Idea¶

A proposed way of meeting a customer need in exchange for payment, stated at any level of detail from a vague hunch to a specific, testable offer.

Example: "Weekly prepared dinners delivered Sunday afternoons to parents who work late" is a more specific version than "healthy food for families."

Business Model Canvas¶

A widely used one-page template, developed by Alexander Osterwalder, that describes how an organization creates, delivers, and captures value using nine building blocks.

The CO.STARTERS version adapts the one-page approach for very early-stage founders, with more emphasis on customers, problems, and alternatives.

Contrast with: CO.STARTERS Canvas

Business Viability¶

The extent to which a venture's economics and genuine customer demand together suggest it can sustain itself as an ongoing operation, not merely survive one enthusiastic test.

Example: A bakery that sells out every weekend but loses money on each loaf because of ingredient costs lacks this quality.

See also: Break-Even Thinking

Call To Action¶

The specific, explicit instruction that tells a reader exactly what to do next after reading a message, such as booking, replying, or paying.

Example: "Text me to book your first session" rather than "Let me know if you're interested."

Canvas Block¶

A single labeled section of the CO.STARTERS Canvas that holds a short, specific answer to one guiding question, deliberately sized to fit on a large index card rather than a full page.

See also: CO.STARTERS Canvas, Canvas Sprint

Canvas Sprint¶

A timed group exercise, typically five to ten minutes per block, in which participants draft an answer individually, compare it briefly with a peer, and then move to the next block.

The time limit keeps founders from polishing one block while the rest of the page stays empty.

Example: In Session 1, participants get seven minutes to write their Customer block, then two minutes to swap drafts with a partner.

Canvas Synthesis¶

The practice of reading all eleven completed blocks together as one coherent argument for why a venture should exist, checking that each answer supports its neighbors rather than contradicting them.

Example: A founder notices her Customer block targets retirees while her Distribution block relies only on a short-video app, and fixes the mismatch.

Capstone Presentation¶

The single culminating deliverable that pulls together everything built across the course into one shared, witnessed moment in front of the cohort.

See also: Mini Pitch

Cash Flow Awareness¶

Understanding not just how much money comes in and goes out of a venture, but exactly when, since a business can be profitable on paper and still run out of cash if expenses land before income.

Example: Priya buys groceries on Friday but gets paid on Sunday, so she needs enough cash on hand to cover the gap.

Channel Cost¶

What a route to customers actually requires to use, measured in money, founder time, or both, including fees, printing, commissions, and hours spent.

Example: Flyers cost $20 to print but three hours to hand out, while a marketplace listing is free to post but takes a cut of every sale.

Channel Fit¶

How well a specific route to customers matches where the actual target customer already spends attention, regardless of which route is cheapest or widest in the abstract.

Example: A grooming service for seniors fits a community-center bulletin board far better than a short-video app.

Channel Reach¶

How many of a venture's target customers a particular route to market can realistically put the offer in front of within a given period.

See also: Channel Fit

Channel Selection¶

The deliberate process of choosing which routes to customers to actually pursue, guided by cost, reach, and fit, rather than trying every option at once.

Example: Jordan picks a neighborhood app and a vet-clinic referral over paid ads because both reach local dog owners cheaply.

See also: Channel Cost, Channel Reach, Channel Fit

Channel Testing¶

Running a small, deliberate trial of a specific route to customers and measuring the actual response before committing further time or money to it.

Example: Jordan posts once in one neighborhood group and counts bookings before deciding whether to post in five more.

Clarity¶

The first phase of the course's Clarity, Validation, Action, Launch cycle: stating in one or two plain sentences who you believe the customer is and what problem you believe they have, as an honest, falsifiable guess.

Example: Jordan's early version read, "Busy dog owners without easy access to a groomer would pay for grooming that comes to them."

See also: Validation, Assumption

CO.STARTERS Canvas¶

A one-page business planning tool with eleven blocks (Customer, Problem, Solution, Alternatives, Benefit, Advantage, Message, Distribution, Revenue, Startup Needs, and Costs) used to describe and test a venture's key assumptions.

It is the organizing structure for this entire course.

Example: Jordan's completed page fits on one sheet and summarizes who he serves, what he offers, and how the grooming business covers its costs.

See also: Canvas Block, Canvas Synthesis

Coaching Handoff¶

The transition point at which a facilitator's structured guidance ends and a founder continues with lighter-touch peer or self-directed support.

See also: Post-Course Support

Cohort-Based Learning¶

An instructional model in which a fixed group of participants moves through a course together on a shared schedule, gaining from the facilitator and from one another's progress and setbacks.

See also: Peer Learning Community, Virtual Learning Lab

Community Hub¶

The shared online space cohort members use throughout the course, which typically remains available afterward for posting updates and asking questions.

See also: Slack Community

Competitive Advantage¶

Any factor that makes an offer harder for a rival to match, which can be as ordinary as having reached customers first.

Example: Jordan's regular Saturday route through one neighborhood makes it hard for a newcomer to win the same households.

See also: Unfair Advantage

Competitive Analysis¶

The step of interpreting gathered information about alternatives to draw conclusions about their strengths, weaknesses, and the openings a new venture could use.

Example: After reviewing four meal-prep services, Priya concludes that none guarantees delivery before the school week starts.

Competitive Intelligence¶

The ongoing, organized collection and interpretation of information about alternatives, kept as a regularly updated record rather than a one-time search.

See also: Competitive Research

Competitive Landscape¶

The full picture of every alternative a target customer has available, including direct rivals, indirect options, workarounds, and doing nothing, organized and understood together rather than one at a time.

See also: Competitive Landscape Mapping

Competitive Landscape Mapping¶

The act of laying out all of a customer's alternatives visually, such as on a spectrum or grid, so their relationships and gaps can be seen at once.

Example: Priya plots competitors on a grid of price versus convenience and spots an empty corner for affordable, scheduled delivery.

Competitive Positioning¶

The deliberate choice of where an offer sits relative to all the alternatives in a customer's mind, such as faster, cheaper, more personal, or more convenient.

Example: Jordan presents his service as "the most convenient option for busy owners," not the cheapest.

See also: Differentiation

Competitive Research¶

The general activity of gathering information, such as prices, features, reviews, and customer complaints, about the existing alternatives available to a target customer, before interpreting what it means.

See also: Competitive Analysis, Competitive Intelligence

Competitor¶

Any business or option that a target customer might choose instead of a venture's offer to address the same need or problem.

See also: Direct Competitor, Indirect Competitor

Concept Validation¶

The overall process of determining whether a venture idea is supported by real-world evidence, ending in a clear status of supported or contradicted.

See also: Validated Concept, Invalid Concept

Continuing Platform Ecosystem¶

The full set of resources, such as templates, community events, and alumni connections, that a course or its host organization makes available beyond the four live sessions.

See also: Community Hub

Core Benefit¶

The single customer outcome that matters most: the one that, if removed, would make the customer stop caring about everything else an offer provides.

Example: For Priya's customers, it is getting dinner on the table on time, not recipe variety or organic ingredients.

Core Offering¶

The single primary product or service a venture is built around, as distinct from any secondary add-ons that might come later.

See also: What You Offer

Cost Estimation¶

Researching or calculating a realistic dollar figure for each item a venture needs, using actual prices rather than rough guesses.

Example: Instead of guessing "maybe $100 for supplies," Priya prices containers at two stores and records $1.20 each.

Cost Structure¶

The organized breakdown of all of a venture's expenses, grouped by category such as one-time needs, fixed costs, and variable costs, so the full financial picture can be seen at once.

Example: Jordan's one-page table shows $450 in startup needs, $110 in monthly fixed costs, and $10 in variable costs per groom.

Cost Tracking¶

The ongoing habit of recording actual spending against the planned budget as it happens, so surprises are caught in the first week instead of months later.

Example: Jordan logs every receipt in a phone spreadsheet and notices by week two that gas is costing twice his estimate.

Cost-Plus Pricing¶

Setting a price by starting from what an offer costs to deliver and adding a fixed margin, which secures profit on paper but ignores what customers would actually pay.

Example: Priya's ingredients and packaging cost $15 per meal, so she adds 50 percent and charges $22.50.

Contrast with: Value-Based Pricing

Costs Block¶

The final section of the CO.STARTERS Canvas, listing the recurring expenses a venture incurs for as long as it keeps operating.

Example: Priya's entry includes weekly groceries, packaging, delivery fuel, and a monthly commercial-kitchen rental.

Contrast with: Startup Needs Block

Current Workaround¶

Any informal, imperfect method a customer has put together to cope with a difficulty in the absence of a satisfying solution.

Example: A dog owner bathes her dog in the backyard with a garden hose because the salon has no weekend openings.

Customer Acquisition Path¶

The actual sequence of steps a real buyer follows from first encountering a venture to becoming a paying one, as observed in practice rather than imagined.

Example: For Jordan: a neighbor sees an app post, texts a question, books a time slot, and pays at the door.

Customer Assumption¶

An unverified belief about who a venture's buyer is and what that person wants, held until field evidence confirms or contradicts it.

Example: "Busy dog owners will pay $40 for driveway grooming" was this kind of belief before Jordan tested it with neighbors.

Customer Avatar¶

A single, vivid individual, illustrated or described in detail, who stands in for an entire target group and is used mainly in marketing and messaging work to keep wording aimed at one real-feeling person.

Example: A bakery owner pins a sketch of "Maria, 34, who orders birthday cakes for her office" above her desk while writing social posts.

Customer Behavior¶

The observable actions, habits, and choices a buyer makes today, which are often a more reliable signal than what that person says they would do.

Example: A parent who says home cooking matters but orders pizza four nights a week is showing a pattern that outweighs the statement.

See also: Customer Motivation

Customer Benefit¶

The value a buyer gains from an offer, expressed as an outcome in their own life rather than as a property of the product.

Example: "Get your Saturday back" rather than "fully equipped mobile grooming unit."

Customer Block¶

The first section of the CO.STARTERS Canvas, identifying the specific group of people a venture intends to serve and who will pay for its offer.

Example: Priya's entry reads, "Dual-income parents of school-age kids who get home after 6 p.m."

See also: Target Customer, Who You Serve

Customer Conversation¶

Any dialogue with a buyer or prospective buyer that produces information useful to a venture, whether structured like an interview or casual like a chat at a store counter.

See also: Customer Interview

Customer Definition¶

The practice of describing, in clear and specific terms, who a venture serves; the umbrella activity that produces the answer recorded in the Customer block.

Example: Moving from "people who like dogs" to "dual-income households with large dogs and no weekday free time" is this practice at work.

Customer Empathy¶

The effort to understand a buyer's situation, frustrations, and priorities from that person's own point of view rather than through the founder's assumptions about them.

Example: Instead of asking parents whether they like healthy food, Priya asks them to walk her through last Tuesday's dinner step by step.

Customer Fit¶

How well a specific buyer description matches what a venture can realistically deliver, regardless of how much that buyer wants the offer.

Example: A customer who needs same-day delivery is a poor match for a founder who can deliver only on weekends.

Customer Identification¶

The research process of determining, through evidence rather than guesswork, which real people actually match a founder's intended description of the buyer.

Example: Jordan reads neighborhood app threads and talks with owners at the dog park to find people who actually complain about grooming logistics.

Customer Interview¶

Any one-on-one research conversation with a current or prospective buyer, of which the early, problem-focused discovery interview is one specific type.

See also: Discovery Interview

Customer Journey¶

The sequence of steps a buyer moves through from first becoming aware of a difficulty to deciding whether to purchase a solution for it.

See also: Customer Acquisition Path

Customer Motivation¶

The underlying emotional or practical reason that drives a buyer's observable actions and choices; the "why" beneath what a person actually does about a difficulty.

See also: Customer Behavior, Emotional Benefit

Customer Needs¶

The specific outcomes or resources a buyer requires to resolve a difficulty, whether or not that person can clearly put them into words.

Example: Busy parents may say they want "healthier food," but what they actually require is a dinner that is ready within 15 minutes of walking in the door.

Customer Pain¶

The negative experience, such as frustration, cost, wasted time, embarrassment, or risk, that a buyer feels as a direct result of an unsolved difficulty.

See also: Pain Point, Problem Severity

Customer Payment Signal¶

An actual transfer of money from a buyer, even a small deposit, which is far harder to fake or misread than a verbal expression of interest.

Example: Three neighbors each send Jordan a $10 deposit through a payment app to reserve a Saturday slot.

Customer Persona¶

A semi-fictional but research-grounded character representing a group of target buyers, given a name, backstory, goals, and frustrations so a founder can reason about decisions from one person's viewpoint.

Example: Priya's "Dana, a nurse working 12-hour shifts with two kids" lets her ask, "Would Dana have time to pick this up on a Tuesday?"

See also: Customer Avatar

Customer Prioritization¶

The act of ranking several candidate buyer groups and choosing which one to pursue first, based on how urgently they feel the problem, how easily they can be reached, and how many of them exist.

Example: Jordan ranks seniors with limited mobility above apartment renters because they feel the problem more urgently and are easy to reach through a local senior center.

See also: Problem Prioritization

Customer Segment¶

A subgroup of a venture's prospective buyers who share meaningful characteristics, such as age, location, behavior, or need, that make them likely to respond to a similar offer in a similar way.

Example: Within "dog owners," Jordan separates apartment dwellers without a car from seniors with limited mobility, since each group has different needs.

See also: Market Segment, Niche Market

Customer-Facing Message¶

Any piece of language a real buyer actually encounters, including flyers, posts, texts, and order forms, as opposed to internal notes, canvas entries, or planning documents.

See also: Messaging Framework

Differentiation¶

What makes an offer meaningfully different from every mapped alternative, grounded in a specific gap found through research rather than a vague claim of being better.

Example: Priya's meals arrive on Sunday afternoon, ready for the whole week, which no competitor in her area offers.

Direct Competitor¶

A business offering essentially the same kind of solution to the same target customer through a similar approach, so customers compare the two side by side.

Example: Another mobile grooming van serving the same suburbs is this for Jordan.

Contrast with: Indirect Competitor

Direct Post Test¶

A lower-commitment lean experiment in which a founder posts an offer directly to a real audience, such as a neighborhood app or community group, and measures genuine responses without one-on-one outreach.

Example: Jordan posts "Driveway dog grooming, Saturdays, $40, reply to book" in a neighborhood app and counts replies over three days.

Direct Sales Channel¶

A route to customers in which the founder personally reaches out to and closes individual buyers one at a time, without an intermediary.

See also: In-Person Distribution

Discovery Interview¶

A structured conversation with a real prospective customer, designed to learn about their difficulty, current behavior, and unmet needs, without pitching or selling anything.

Example: Priya asks a parent, "Walk me through what dinner looked like last Tuesday," and listens for twenty minutes without mentioning her business.

See also: Asking Not Selling, Open-Ended Question

Distribution Block¶

The section of the CO.STARTERS Canvas that identifies how a venture will reach its target customers and get its offer into their hands.

Example: A tutoring founder lists "school parent newsletter, referrals from two teachers, and a neighborhood app."

Distribution Channel¶

Any specific path or method through which a customer discovers, learns about, and ultimately accesses a venture's offer, whether online, in person, or through another business.

See also: Distribution Block, Channel Selection

Do-Nothing Alternative¶

The option of a customer simply continuing to tolerate a difficulty, unsolved, rather than adopting any solution; for most problems it is the default rival a venture has to beat.

Example: Many dog owners just wait two extra months between grooms instead of paying anyone.

See also: Status Quo

Domain Expertise¶

Direct knowledge or experience in a specific problem area, gained through work, study, or lived experience, that helps a founder understand customers and deliver a solution better than an outsider could.

Example: A former accountant starting a bookkeeping service for freelancers brings years of tax-season experience.

Draft Business Idea¶

A rough, unpolished first written pass at what a venture's solution might be, recorded specifically so it can be tested and changed rather than kept vague and unfalsifiable.

Example: Priya's first note read, "Healthy family dinners, delivered, weekly subscription, maybe $120?"

See also: Unrefined Concept

Early Adopter¶

A buyer who actively seeks new solutions to a problem they already recognize, tolerates an imperfect first version, and often recommends it to others if it works.

Example: A parent who has already tried three meal kits and still complains about weeknight dinners is likely to try Priya's rough first version.

Contrast with: Mainstream Customer

Early-Stage Venture¶

A new business effort that has not yet proven it has paying customers or a repeatable way to reach them, typically run by one founder or a small team with limited money and time.

Example: Jordan's mobile dog-grooming idea, with no van, no bookings, and one practice groom in a neighbor's driveway, fits this description.

Elevator Pitch¶

A brief spoken version of a value proposition, typically 30 to 60 seconds long, designed for delivery in a chance encounter.

Example: At a school event, Priya explains who she serves, the 6 p.m. problem, and her Sunday delivery in under a minute.

Emotional Benefit¶

A feeling a customer gains from an offer, such as relief, confidence, pride, or reduced guilt, often as important to the buying decision as any practical gain.

Example: Parents using Priya's service say they feel less guilty about feeding their kids takeout.

Contrast with: Functional Benefit

Entrepreneurship¶

The practice of identifying a problem people have, designing a way to address it, and organizing time, money, and effort to deliver that solution in exchange for payment, while accepting uncertainty about whether it will work.

This course treats it as a learnable set of habits rather than a personality trait.

Example: A parent who notices neighbors struggling with weekday dinners, tests a small meal-prep service, and begins charging for it is practicing this.

See also: Early-Stage Venture, Founder Mindset

Essential Bills Priority¶

The tendency of customers to direct limited money first toward non-negotiable obligations such as rent, groceries, utilities, and debt before spending on any discretionary problem, however real it is.

Example: A family that loves Priya's meals but is behind on rent will pay the rent first, no matter how much they want the service.

Evidence Of Demand¶

Any signal that real customers actually want a solution, such as expressed interest, engagement, sign-ups, or requests for more information.

See also: Customer Payment Signal

Evidence-Based Decision Making¶

Choosing what to do next with a venture based on what real customers actually said, did, or paid for, rather than on the founder's hopes, opinions, or the enthusiasm of friends and family.

Example: Priya changed her delivery schedule because interviews showed timing was the barrier, even though she had planned to spend the week improving recipes.

Existing Solution¶

Any product, service, or method, commercial or not, currently available to a customer for addressing a difficulty, whether or not the customer actually uses it today.

See also: Status Quo

Feature Vs Benefit¶

The distinction between what a solution technically does or includes and the positive outcome a customer actually experiences as a result of it.

Example: "Text-message booking" describes a capability; "book a groom in 30 seconds without a phone call" describes the outcome the customer cares about.

See also: Customer Benefit

Field Discovery Window¶

The seven-day interval between each of the four live sessions, during which participants leave the cohort to test their assumptions with real people rather than continuing to plan inside the group.

Example: Between Sessions 1 and 2, Priya used her week to interview six parents at school pickup about weeknight dinners.

See also: Field Research, Real-World Customer Friction

Field Research¶

Evidence gathered directly from real people in their own context, through conversations, observation, and small experiments, as opposed to information collected at a desk.

See also: Qualitative Research, Field Discovery Window

Financial Baseline¶

The starting monetary position of a venture, established through realistic estimates and a lean budget, against which every future month can be measured.

Example: Jordan's shows $450 spent to start, $110 in monthly fixed costs, and zero revenue on day one.

Five-Second Test¶

Showing a message for exactly five seconds and then asking the reader to describe, from memory, what the business offers; the most common version of an outsider comprehension check.

Example: If a reader of Priya's post can recall only "something about food," the post needs simplifying.

Fixed Costs¶

Recurring expenses that stay the same each period regardless of how much a venture sells, such as insurance, a phone plan, or a storage-unit rental.

Example: Jordan's monthly insurance premium stays the same whether he grooms five dogs or fifty.

Contrast with: Variable Costs

Founder Advantage¶

The combination of experience, relationships, skills, timing, or circumstance that makes a particular person unusually well suited to address a particular difficulty for a particular customer.

Example: Jordan's three years as a veterinary technician and his existing relationships with local dog owners.

See also: Domain Expertise

Founder Credibility¶

The evidence a person can point to, such as a track record, relevant background, or direct proof, that makes a claim of advantage believable to customers.

Example: Jordan's three successful driveway sessions and the positive comments neighbors posted afterward.

Founder Mindset¶

The cluster of thinking habits and attitudes toward risk, failure, and evidence that let a person behave like a business builder before anything has launched; it is treated as learnable rather than innate.

Example: Treating a rejected pre-sale offer as useful data instead of a personal defeat reflects this set of habits.

See also: Growth Mindset, Founder Resilience

Founder Narrative¶

An expanded, messaging-ready version of a founder's personal account of why they are pursuing a venture, shaped for use in customer-facing language.

Example: Jordan's flyer describes how his own dog's car-ride anxiety led him to start grooming in driveways.

See also: Founder Story

Founder Resilience¶

The capacity to keep taking constructive action on a venture despite setbacks, rejections, or failed tests, by treating each one as information rather than as a verdict on personal worth.

Example: After five parents decline her first offer, a tutor revises the price and schedule and runs a second test the following week.

See also: Setback Normalization, Growth Mindset

Founder Story¶

A short personal account explaining why a particular person is pursuing a particular venture, connecting their own experience or motivation to the problem they chose to address.

It is shared early in Session 1 as a trust-building exercise.

Example: Priya opens hers with, "For two years I was the parent eating drive-through dinners in the car three nights a week."

See also: Founder Narrative

Freemium Model¶

A pricing arrangement that offers a basic version of a solution for free while charging for a premium version with extra features, best suited to offers where serving one more user costs very little.

Example: A budgeting app gives away expense tracking but charges $5 a month for tax-ready reports.

See also: Tiered Pricing

Functional Benefit¶

A practical, measurable outcome a customer gains from an offer, such as time saved, money saved, or a task completed.

Contrast with: Emotional Benefit

Go-To-Market Approach¶

The overall strategy for reaching and acquiring customers, combining one or more routes to market with a venture's messaging into a coherent plan.

Example: Priya's plan pairs posts in two school parent groups with a referral discount for existing customers.

Growth Mindset¶

The belief, popularized by psychologist Carol Dweck, that abilities can improve through effort, practice, and feedback, which leads a person to treat mistakes and failed tests as chances to get better.

Example: A founder who has never written sales copy drafts three versions, studies which one gets replies, and applies the lesson to the next draft.

Headline Writing¶

Crafting the very first line a reader sees, which does most of the work of earning attention for the rest of a message.

Example: "Your dog, groomed in your driveway" instead of "Welcome to Jordan's Grooming."

High-Conversion Copy¶

Persuasive wording that actual testing has shown to produce a meaningfully higher rate of customer action than alternative wording, rather than wording merely believed to work.

Example: Priya's "Dinner's done before homework starts" drew noticeably more replies than "Healthy meal prep for families" when she posted both.

How To Reach Them¶

The element of the 30-day plan that restates the chosen distribution channels as the actual methods that will be used, not every method that was considered.

Example: Priya's: "Two school parent groups online and a referral discount for current families."

Idea Trap¶

The pattern in which a founder responds to the discomfort of an untested concept by retreating into more private planning, such as polishing pitches, logos, or spreadsheets, instead of testing it with real customers.

The course's four-session structure is designed to pull participants out of this pattern early.

Example: Spending three weekends designing a logo and website for a tutoring service before asking a single parent whether they would pay is a classic case.

See also: Lean Startup Philosophy, Messy Idea Normalization

Ideal Customer Profile¶

A description of the specific combination of demographic or organizational traits, such as household type, income, location, industry, or company size, that marks someone as the best possible fit for a venture's offer.

Example: A freelance bookkeeping service might describe "solo creative professionals earning $60,000 to $150,000 who pay quarterly estimated taxes."

Contrast with: Customer Persona

In-Person Distribution¶

Reaching customers through physical presence, such as a booth at a local event, a flyer on a community board, or a conversation at the dog park.

Example: Jordan hands out cards at a Saturday dog-adoption event.

Contrast with: Online Distribution

Indirect Competitor¶

A business that addresses the same underlying customer need through a different kind of solution or approach, so it competes for the same money without looking similar.

Example: A grocery store's prepared-meal counter competes this way with Priya's delivered family dinners.

Contrast with: Direct Competitor

Initial Offer¶

The specific, concrete version of the smallest workable solution that a founder first presents to real customers during the opening round of field testing.

Example: Jordan's first: "A single dog wash and brush-out, at your home, for $40, this Saturday."

Interview Bias¶

Systematic distortion of what a customer actually believes, caused by how a question was asked or by the researcher's behavior rather than by the customer's genuine views.

Example: Interviewing only friends, who want to be supportive, makes Jordan's idea look more popular than it really is.

Interview Debrief¶

The short reflection a founder does immediately after each customer conversation, ideally within minutes, capturing what was actually said before memory blurs it with what was expected.

Example: Priya sits in her car after each school-pickup conversation and types five bullet points into her phone.

See also: Interview Finding

Interview Finding¶

A specific, factual takeaway from a single customer conversation, recorded as what the person actually said or did rather than as the founder's interpretation.

Example: "Parent said she orders pizza on Tuesdays and Thursdays because of soccer practice."

Interview Question¶

Any single prompt a founder poses during a research conversation with a prospective buyer, worded either to invite honest, open answers or, less usefully, to nudge the person toward a particular response.

See also: Interview Script

Interview Recruitment¶

The process of finding and inviting real prospective customers to take part in a discovery conversation, through personal networks, neighborhood apps, online communities, or direct outreach.

Example: Priya posts in her school's parent group asking for fifteen minutes with anyone who "dreads 6 p.m. on weeknights."

Interview Sample Size¶

The number of customer conversations needed before treating a pattern as meaningful rather than coincidence; for early qualitative research, three to five is often enough to spot a real pattern.

See also: Pattern Recognition

Interview Scheduling¶

The logistical work of actually setting a time for a customer conversation that happens, a step where many good intentions quietly fail.

See also: Interview Recruitment

Interview Script¶

The prepared, written set of questions a founder plans to ask in a discovery conversation, kept short enough to leave room for follow-up and listening.

Example: Jordan's has six questions, starting with "How do you currently get your dog groomed?"

Interview Surprise¶

Anything a customer said or did during a conversation that contradicted what the founder expected going in; often the most valuable kind of research takeaway.

Example: Priya expected parents to complain about taste, but they kept saying timing was the real barrier.

Interview Synthesis¶

Pulling the findings from a full round of customer conversations into a short written summary of what they showed, ready to update the canvas.

Example: Jordan's one-paragraph summary: "Owners value convenience over price; weekends matter most; car anxiety is common."

Invalid Concept¶

A venture idea for which the evidence consistently contradicts the original hypothesis, regardless of how appealing the idea still feels to its founder.

Contrast with: Validated Concept

Job To Be Done¶

The underlying task or outcome a customer is fundamentally trying to accomplish, independent of any particular product or feature used to accomplish it; a framing associated with Clayton Christensen.

Example: "Get a nutritious dinner on the table with zero advance planning" is the task behind a parent's interest in meal prep.

Kill Decision¶

The deliberate choice to stop pursuing a specific venture idea, or one version of it, because accumulated results consistently fail to clear the threshold set in advance.

The course treats it as a sound use of evidence, not a personal failure.

Example: After three rounds with zero deposits, a founder stops pursuing a dog-walking app and redirects her time to a different idea.

See also: Pivot Decision, Persevere Decision

Launch¶

The fourth phase of the course cycle: committing to a first real version of the business and putting it in front of actual customers, even though it is still incomplete.

An incomplete offer in the real world produces more useful evidence than a perfect one that never leaves the notebook.

Example: A home baker who begins taking weekly pre-orders from a neighborhood group, with only three items on the menu, has reached this phase.

See also: Thirty-Day Launch Plan, Launch Readiness

Launch Confidence¶

A founder's grounded, evidence-based belief that a venture is ready to continue past the course, based on real test results rather than optimism alone.

See also: Launch Readiness

Launch Readiness¶

An evaluated state confirming that a venture has enough demand evidence, a workable offer, and a functioning way to reach customers to keep operating beyond its first 30 days.

It means enough real evidence to continue, not perfection.

Example: At day 30, Jordan has twelve repeat customers, a stable $40 price, and steady bookings from the neighborhood app.

See also: Launch Confidence

Launch Roadmap¶

The overall structure that organizes 30 days of post-course action into a sequence, replacing a long theoretical business plan with something short enough to follow and revise.

Example: Jordan's is a single page with four weekly columns and three rows: what to sell, who to sell to, and how to reach them.

Leading Question¶

A prompt worded in a way that suggests the desired answer, nudging a person toward agreement rather than an honest response.

Example: "Wouldn't it be great if grooming came to your house?"

Contrast with: Open-Ended Question

Lean Startup Philosophy¶

An approach to building new ventures, popularized by Eric Ries, that treats a business idea as a set of testable beliefs and favors small, fast, cheap experiments and customer feedback over detailed long-range planning.

It is the philosophy underneath every exercise in this course.

Example: Instead of writing a five-year business plan, a founder runs a one-week pre-sale test to see whether anyone pays.

See also: Build-Measure-Learn, Validated Learning

Lean Test¶

One specific, bounded real-world trial designed to produce evidence about a single belief, run cheaply enough that a negative result does no real harm.

Example: A tutor offers five $20 trial sessions to parents in one school group to see whether any of them book.

Lean Validation¶

The overall practice of checking a venture's key beliefs through small, fast, low-cost real-world experiments before committing significant time or money to building anything at full scale.

See also: Lean Test, Lean Startup Philosophy

Low-Capital Testing¶

Running experiments with as little money as possible, so a negative result costs almost nothing and more trials fit within a limited budget.

Example: Jordan's driveway sessions cost only shampoo and gas, which let him run three of them in one week.

See also: Bootstrapped Funding

Mainstream Customer¶

A buyer who waits until a solution is proven, polished, and recommended by others before trying it, relying on evidence that earlier buyers have already gathered.

Contrast with: Early Adopter

Manual Before Automated¶

The lean principle of doing work by hand, such as a spreadsheet instead of software or a text message instead of an app, until the underlying idea has been shown to work.

Example: Jordan tracks bookings in a notebook and confirms appointments by text rather than paying for scheduling software.

Manual Service Delivery¶

A lean experiment in which the founder personally performs the work by hand for a real customer, combining the service-first and hand-done principles in a single trial.

Example: Jordan's $40 driveway grooming sessions using a borrowed car and his own clippers.

Market Gap¶

A genuine, customer-confirmed shortfall shared by every current alternative: something the existing options consistently fail to deliver that a target customer actually wants.

Example: No groomer in Jordan's area offers at-home appointments on weekday evenings.

Market Segment¶

The general marketing term for a portion of a larger population of buyers whose members share characteristics that make them respond similarly to an offer; the same idea as a customer segment, applied at a wider scale.

See also: Customer Segment, Broad Market

Marketplace Channel¶

A route to customers through a third-party platform that lists many similar offers together, trading some independence and fees for built-in customer traffic.

Example: A tutor lists her sessions on an online tutoring marketplace that takes a commission on each booking.

Message Block¶

The section of the CO.STARTERS Canvas that records the short, plain-language wording a venture uses to tell target customers what it offers and why they should care.

Example: "Grooming in your driveway: no car ride, no crate, no lost afternoon."

See also: One-Sentence Value Proposition

Message Clarity¶

The property of customer-facing language being understandable on a single read, with no jargon the target customer would not use themselves.

Example: "We groom your dog in your driveway" works; "mobile pet aesthetic solutions" does not.

See also: Message Simplicity

Message Simplicity¶

Stripping customer-facing language down to only what is essential for a reader to understand an offer and act on it.

Example: Priya cuts her flyer from five benefits to one: "Dinner ready in 15 minutes, all week."

Message Testing¶

The general practice of checking customer-facing language against real outside readers, using methods such as comprehension checks or side-by-side posts, before relying on it.

See also: Five-Second Test, Messaging Iteration

Messaging Framework¶

The structured, repeatable process the course uses to turn a tested value proposition into finished customer-facing language, moving from one core sentence to longer formats such as pitches, flyers, and posts.

See also: Message Block

Messaging Iteration¶

The ongoing process of revising customer-facing language based on test results, so the wording gets sharper as more real reactions come in.

Example: Priya changes "meal prep" to "Sunday dinner delivery" after several parents said "meal prep" sounded like more work.

Messaging Workshop¶

A focused working session, often with cohort peers, in which a founder drafts and pressure-tests customer-facing language the same way earlier sessions challenged canvas assumptions.

Example: Cohort members swap headlines, and each reads a partner's aloud to find where listeners get confused.

Messy Idea Normalization¶

The cohort norm of treating incomplete, contradictory, or unpolished venture concepts as an expected stage of building a business, rather than something to hide until it looks ready.

Example: The Session 1 "three-word pitch" asks everyone to describe their venture in exactly three words, so no one can hide behind polish.

See also: Idea Trap, Psychological Safety

Milestone-Driven Plan¶

A roadmap organized around specific, checkable checkpoints with dates and numbers attached, rather than around vague intentions or ongoing effort.

Example: "Week 3: eight paying families" instead of "keep working on marketing."

Mini Pitch¶

The course's closing exercise: a short, structured presentation of a founder's tested concept, canvas, and 30-day launch plan, delivered to the cohort as the capstone deliverable.

Example: In Session 4, Priya presents her Sunday dinner service, her deposit results, and her four weekly milestones.

See also: Two-Minute Pitch, Capstone Presentation

Minimal Viable Budget¶

The smallest spending plan that still covers every genuine need identified through a needs-versus-wants review, with no padding or just-in-case purchases.

Example: Priya drops a designed logo and a new stand mixer, keeping only containers, groceries, and a food-handler certificate.

See also: Needs Vs Wants Assessment

Minimum Testable Iteration¶

The smallest possible version of an offer capable of producing a real yes-or-no signal from a real customer, scoped around what one experiment needs to reveal rather than around a general first offering.

Example: Priya cooks one Sunday batch for four families to learn whether they will pay upfront, with no menu, website, or packaging design.

See also: Minimum Viable Offer, Smallest Testable Version

Minimum Viable Offer¶

The smallest, simplest version of a solution capable of genuinely resolving a customer's core difficulty, containing only what is essential to check whether the underlying idea works.

Example: For a meal-prep service, three family dinners delivered once a week, with no app, no menu choices, and no custom diets.

See also: Minimum Testable Iteration, Solution Simplicity

Momentum Building¶

The deliberate practice of stacking small, visible wins across the 30 days, such as a first booking or first referral, so progress stays motivating before the venture is fully proven.

Example: Priya posts each new sign-up in the cohort's online community, and each post draws encouragement from peers.

Money-Saving Pivot¶

A small adjustment to a launch plan that reduces what a step costs, without changing the venture's customer, problem, or core offer.

Example: Priya switches to a cheaper container supplier and delays buying a second freezer.

Multi-Channel Strategy¶

Deliberately using more than one route to customers at once, chosen because the routes reach different, complementary parts of the target customer base.

Example: A bakery uses a farmers market for walk-up buyers and an online pre-order form for regulars.

Needs Vs Wants Assessment¶

The practice of examining every item on a founder's resource list and asking whether the venture can launch and run its first lean test without it, separating genuine necessities from items that only feel urgent.

Example: Jordan keeps clippers and a license but moves a custom-wrapped van to the "later" list.

Niche Market¶

A segment small and specific enough that a single small venture could realistically become the obvious choice for everyone in it, rather than one option among hundreds.

Example: "Large-breed dog owners in three suburbs without a nearby groomer" is small enough for one grooming van to become the go-to choice.

Contrast with: Broad Market

Offer Clarity¶

The property of a proposal to customers being stated so plainly and specifically that a buyer immediately understands what they would get and for how much, with no follow-up questions required.

Example: "A single dog wash and brush-out, at your home, for $40" leaves nothing to guess.

See also: Message Clarity

Offer Design¶

The overall process of shaping which features, format, and terms make up a solution, guided by which outcomes matter to the target customer rather than which features are easiest to build.

Example: Priya drops menu customization and adds a guaranteed Sunday 4 p.m. delivery window because timing mattered more to parents than choice.

One-Sentence Value Proposition¶

A benefit-and-advantage statement compressed into a single sentence that a customer could read in under ten seconds and immediately understand.

Example: "Healthy family dinners, delivered Sunday, ready in 15 minutes all week."

See also: Elevator Pitch

One-Time Needs¶

Individual items purchased or acquired a single time to start a venture, such as a piece of equipment or a certification, with no expectation of repeating that expense regularly.

See also: Startup Needs

One-Time Pricing¶

Charging a customer a single amount for a single transaction, with no ongoing commitment from either the customer or the venture after the purchase.

Example: Jordan's $40 per groom, paid at the door.

Contrast with: Subscription Pricing

Ongoing Costs¶

Expenses that recur regularly for as long as a venture keeps operating, recorded in the final block of the CO.STARTERS Canvas.

Example: Priya's weekly groceries, packaging, delivery fuel, and monthly kitchen rental.

Contrast with: Startup Needs

Online Distribution¶

Reaching customers through internet-based platforms such as websites, apps, search, or online marketplaces, where a customer can often discover and buy without in-person contact.

Contrast with: In-Person Distribution

Open-Ended Question¶

A prompt that invites a person to answer in their own words and cannot be answered with a simple yes or no.

Example: "Tell me about the last time getting dinner on the table was hard."

Contrast with: Leading Question

Operational Roadmap¶

The 30-day post-course plan once it serves as a founder's actual working guide for running the business each day, rather than an assignment completed for the course.

Example: Jordan checks his roadmap each morning to decide which neighborhood to post in and which bookings to confirm.

Outsider Comprehension Test¶

Showing a message to someone with no prior context about a venture and checking whether they can accurately repeat back what the business does.

Example: Jordan shows his flyer to a coworker who knows nothing about his plans and asks, "What am I selling?"

See also: Five-Second Test

Pain Point¶

One specific, nameable instance of the frustration, cost, or wasted time a customer experiences, concrete enough to describe in a single sentence rather than as a general complaint.

Example: Not "grooming is a hassle" but "I have to take an unpaid afternoon off work to drive forty minutes each way."

See also: Customer Pain

Partnership Channel¶

A route to customers through an agreement with another business that already has access to the same target customer, often with referrals or benefits flowing both ways.

Example: A veterinary clinic hands out Jordan's cards to clients, and he sends grooming customers who need checkups back to the clinic.

Pattern Recognition¶

The act of noticing which findings repeat across multiple independent customer conversations rather than appearing in just one, separating real signals from one-off comments.

Example: Four of five dog owners separately mention car-ride anxiety, turning a single comment into a meaningful signal.

See also: Interview Synthesis

Peer Accountability¶

Cohort members regularly checking in on each other's progress toward stated commitments, extending the course's peer learning beyond its live sessions.

See also: Accountability Network

Peer Feedback¶

Specific, evidence-based reactions from fellow founders responding to a pitch or plan, following the cohort's constructive, non-judgmental norms and naming something concrete the presenter can act on.

Example: "Your price looks solid, but which channel brought in your first three customers?" names something concrete to act on.

Peer Learning Community¶

A group of fellow founders who exchange feedback, share field results, and gain from one another's successes and mistakes, both during and after formal instruction.

Example: A cohort member posts her direct post test results, and three peers suggest ways to sharpen her headline before she tries again.

People Resource Needs¶

Any labor, skill, or assistance a venture requires beyond the founder's own effort, including occasional or part-time help during busy periods.

See also: Resource Needs

Perceived Problem¶

A difficulty a founder believes customers have, based on logic, outside research, or personal experience, that has not yet been confirmed by talking with the actual target customer.

Example: A founder assumes pet owners worry about grooming-product ingredients, but no one she interviews ever mentions it.

Contrast with: Real Problem

Persevere Decision¶

The choice to continue with the current concept largely as designed because test evidence consistently supports it, moving on to the next or larger trial rather than making major changes.

Example: Jordan's driveway sessions meet his booking target three weeks in a row, so he continues as planned.

Persuasive Writing¶

The craft of using structure, word choice, and emphasis to make a true claim land with maximum impact on a reader.

See also: Sales Copy

Pivot Decision¶

The choice to change one significant element of a concept, such as the customer, problem framing, solution, or pricing, while keeping the parts that evidence has supported, rather than starting over.

Example: Priya keeps her customers and her meals but moves delivery to Sunday after interviews reveal that timing was the real barrier.

Post-Course Support¶

Any continued access to coaching, community, or resources available to a founder after the live sessions end, so progress and confidence do not rest on the founder alone.

See also: Coaching Handoff

Pre-Sale Offer¶

A lean experiment in which a founder asks a customer to pay, in full or as a deposit, for something before it is fully created or delivered.

Example: A baker takes $15 prepayments for holiday pies two weeks before baking them.

Pre-Selling Before Building¶

The lean principle of asking customers to actually pay, even a deposit, before an offer fully exists, because stated interest costs a customer nothing while real payment costs something.

Example: Priya collects $20 deposits for a first week of meals before renting any kitchen time.

See also: Pre-Sale Offer

Pressure Test¶

The general practice of deliberately trying to break a venture idea by exposing it to hard questions before the market does so less kindly.

Example: A bakery founder asks a peer to argue why no one would pre-order bread, then checks each argument against her own data.

Price Point Testing¶

A lean experiment in which the same or similar offer is presented at different prices to different customers to observe how buying behavior changes.

Example: A tutor quotes $40 to one parent group and $55 to another and compares how many book.

Pricing Communication¶

How a price is presented to a customer, clearly, honestly, and without hidden terms, using the same clarity and simplicity principles as any other customer-facing language.

Example: "$40 per groom, all-inclusive, no travel fee" instead of "Starting at $30*."

Pricing Model¶

The specific structure by which a charge is set and collected from a customer, narrower than a venture's overall pattern of income.

Example: Jordan charges a flat $40 per session regardless of dog size, while a competitor charges by the dog's weight.

Pricing Strategy¶

The reasoning behind why a particular way of charging was chosen, tied back to the target customer, the value proposition, and the alternatives available.

Example: Priya sets her price just below what a family of four spends on a week of takeout, because takeout is what parents compare her to.

See also: Value-Based Pricing

Pricing Validation¶

Confirming, through real transactions rather than opinions, that a chosen price produces enough paying customers, often enough, to sustain a venture over time.

Example: Jordan confirms $40 works after fifteen paid bookings in one month with few complaints about cost.

See also: Price Point Testing

Problem Block¶

The section of the CO.STARTERS Canvas that states the specific, confirmed difficulty or unmet need the target customer experiences and that a venture intends to address.

Example: "Parents run out of time between after-school pickup and bedtime to put a healthy dinner on the table."

Problem Definition¶

The practice of stating, in specific and falsifiable terms, the difficulty a target customer experiences that a venture intends to address, precise enough that evidence could show the statement true or false.

Example: "Parents struggle to cook" becomes "Dual-income parents who get home after 6 p.m. rely on takeout three or more nights a week and feel guilty about it."

See also: Problem Statement, Problem Framing

Problem Discovery¶

The ongoing process of finding and sharpening statements of customer difficulty through direct contact with customers, continuing whenever new field evidence complicates earlier conclusions.

See also: Discovery Interview, Field Research

Problem Framing¶

The choice of how to word a customer's difficulty, including which details to include, which customer language to borrow, and which angle to emphasize, knowing each wording steers the solution in a different direction.

Example: Wording Priya's issue as "parents lack cooking skills" points toward classes, while "dinner help arrives at the wrong time" points toward scheduled delivery.

Problem Frequency¶

A measure of how often a customer's difficulty recurs, whether daily, weekly, or rarely, independent of how painful any single occurrence is or how soon a fix is wanted.

Example: Deciding what to make for dinner comes up every day, so it rates high on this measure even when each instance is only mildly annoying.

See also: Problem Severity, Problem Urgency

Problem Prioritization¶

The act of ranking several candidate customer difficulties and choosing which one to pursue first, using evidence about severity, frequency, and urgency rather than personal preference.

Example: A tutor chooses "failing math grades right before finals" over "general homework stress" because parents act on the first one immediately.

Problem Severity¶

A measure of how painful, costly, or disruptive a customer's difficulty is on any single occurrence, independent of how often it happens or how soon the customer wants it fixed.

Example: A flooded basement rates high on this measure even though it may happen only once a decade.

See also: Problem Frequency, Problem Urgency

Problem Statement¶

The specific written sentence describing a customer's difficulty that goes into the Problem block, often following a pattern such as "[customer] struggles with [pain], caused by [root cause], which matters because [impact]."

Example: "Working parents struggle to serve healthy weeknight dinners because they get home after 6 p.m., which leads to takeout four nights a week."

Problem Urgency¶

A measure of how soon a customer wants a difficulty resolved, whether this week, this year, or someday, independent of how severe or how frequent that difficulty is.

Example: A parent whose child has a math final in two weeks feels far more of it than one who vaguely wants better grades someday.

Problem Validation¶

The process of confirming, through direct evidence from target customers, that a believed difficulty actually exists and matters enough to them to act on.

See also: Perceived Problem, Discovery Interview

Problem-Solution Fit¶

The degree to which a proposed offer actually addresses the confirmed root cause of a customer's difficulty, rather than only its surface symptom.

Example: A faster-to-cook meal kit scores poorly on this if the real issue is that deliveries arrive on the wrong day.

Product Offering¶

A solution delivered as a tangible or standardized item that the customer owns or consumes, produced once and sold repeatedly with little variation from one buyer to the next.

Contrast with: Service Offering

Psychological Safety¶

A shared group condition in which participants feel free to share rough ideas, admit mistakes, and ask questions without fear of embarrassment or judgment from peers or facilitators.

The cohort depends on it so that members bring honest, unfinished work instead of polished versions.

Example: A cohort member admits her tutoring post got zero responses, and peers reply with questions about her headline rather than criticism.

Public Commitment¶

A specific, witnessed promise a founder makes to the cohort about what they will do in the next 30 days, drawn directly from their launch roadmap.

Example: Jordan tells the group, "By the end of next month, I will have twelve paying grooming customers."

See also: Accountability Network

Qualitative Research¶

Evidence that captures opinions, motivations, and experiences in people's own words, as distinct from quantitative evidence that measures how many or how much.

See also: Field Research

Rapid Experimentation¶

Running cycles of trial and feedback quickly, in days rather than months, so a wrong direction is corrected cheaply and early.

See also: Build-Measure-Learn

Real Problem¶

A difficulty that customers actually experience and can describe from their own frustration when asked, confirmed through evidence rather than founder intuition.

Example: Seven of ten parents independently described scrambling for dinner after late pickup, confirming the difficulty existed beyond Priya's own experience.

Contrast with: Perceived Problem

Real-World Customer Friction¶

The resistance, indifference, confusion, or outright rejection a founder meets when testing a venture with actual people outside the cohort, in contrast to the supportive environment inside it.

Example: Jordan's flyer drew no replies in one apartment complex, and two dog owners told him they already had a groomer they liked.

Reality Check Exercise¶

The course's signature structured challenge session, usually done with cohort peers, in which a founder's canvas assumptions are tested directly against the interview evidence gathered rather than against opinion.

Example: A peer asks Jordan, "Which of your five interviews supports the $40 price?" and he realizes only one did.

See also: Pressure Test, Assumption Testing

Recurring Revenue¶

Income collected repeatedly from the same customer on an ongoing basis, such as a subscription that renews each week or month without a new sales effort.

Contrast with: Transaction Revenue

Referral Channel¶

A deliberate system that encourages and rewards existing customers for bringing in new ones, turning the natural habit of recommending into a designed route to new business.

Example: Jordan gives $10 off the next groom for every new neighbor a customer sends his way.

Contrast with: Word Of Mouth

Resource Needs¶

The umbrella category for anything a venture requires to operate, divided into three kinds: people (help and skills), technology (tools and equipment), and activities (steps completed before launch).

Example: A tutoring service requires a backup tutor, a video-call account, and a completed background check.

See also: People Resource Needs, Technology Resource Needs, Activity Resource Needs

Revenue Assumption¶

An unverified belief about what a customer will pay for an offer and how often they will buy, held until real transactions confirm or contradict it.

See also: Willingness To Pay

Revenue Block¶

The section of the CO.STARTERS Canvas that describes how a venture earns money, including what customers pay, how often, and through which payment arrangement.

Example: "$120 per week subscription, billed every Friday for the following week's meals."

Revenue Model¶

The overall structure describing how a venture generates income from its offer; not a specific dollar amount, but the pattern by which money flows in.

Example: Priya's is a weekly subscription, while Jordan's is pay-per-session.

See also: Revenue Stream, Pricing Model

Revenue Projection¶

An estimate of future income built from real evidence, such as actual prices and test results, rather than optimistic guessing.

Example: Jordan estimates $640 a month from 16 bookings at $40, based on his actual first-month booking rate.

See also: Sales Conversion

Revenue Stream¶

A distinct source of income within a venture, which may come from a different offer, customer segment, or payment arrangement than the venture's other sources.

See also: Revenue Model

Root Cause¶

The underlying condition actually producing a customer's complaint, often several layers beneath the first explanation anyone gives when asked why the difficulty happens.

Example: Parents first told Priya they disliked meal-kit recipes, but repeated "why" questions revealed the real source: kits arrived midweek, after the busiest nights had already passed.

See also: Symptom Vs Root Cause

Sales Conversion¶

The rate at which people who show interest actually become paying customers, measured directly from field test results rather than estimated.

Example: If 20 parents reply to Priya's post and 5 of them pay, her rate is one in four.

Sales Copy¶

Any written or spoken language intended to persuade a customer to take action, as distinct from purely informational language such as a price list or FAQ.

Example: "Book your Saturday driveway groom; only six slots left this month" persuades, while a price list only informs.

See also: Call To Action

Service Before Product¶

The lean principle of trying out an idea by delivering it as hands-on, personally performed work first, even if the eventual vision is a packaged item.

Example: A founder who dreams of a meal-planning app first plans meals personally for five families by text message.

See also: Manual Before Automated

Service Offering¶

A solution delivered as a performed activity, adjusted in the moment to a specific customer's situation and consumed as it is delivered rather than owned afterward.

Example: Jordan's driveway grooming session, tailored to each dog's coat and temperament.

Contrast with: Product Offering

Serviceable Market¶

The portion of a niche or segment that a specific venture, with its actual resources and location, could realistically reach and deliver to, as opposed to a theoretical total with unlimited resources.

Example: Jordan's is not every frustrated dog owner in the country but the ones within a 20-minute drive of his home.

Setback Normalization¶

Treating a missed weekly target or a failed test as an expected, ordinary part of a plan rather than a sign that something has gone wrong.

Example: When only two of five planned families sign up in week one, Priya adjusts her outreach instead of questioning the whole venture.

Slack Community¶

The specific messaging platform, Slack, that hosts the course's ongoing online space, where founders keep posting updates and asking for input after the final session.

See also: Community Hub

Smallest Testable Version¶

The minimum amount of evidence needed to judge a single hypothesis, sized so the result is neither too small to mean anything nor so large that the trial stops being cheap and fast.

Example: Five direct asks to neighbors is enough to judge Jordan's price; one ask is too few, and a hundred is more than he needs.

A route to customers through content posted on social platforms, whether through regular posts, community groups, or paid promotion, relying on customers already spending time there.

See also: Social Media Copy

A short adaptation of a venture's customer-facing language built for the constraints and conventions of social platforms, such as character limits, images, and fast-scrolling audiences.

Example: A bakery's post reads, "Sourdough Saturdays are back. Pre-order by Thursday; link in bio."

Solution Assumption¶

An unverified belief that a specific offer will resolve a customer's confirmed difficulty well enough that the customer will choose it over the alternatives.

Example: "Parents will prefer fully cooked meals over meal kits" stays an untested belief until Priya sees which option people actually buy.

Solution Block¶

The section of the CO.STARTERS Canvas that describes the offer, whether a product, a service, or both, that a venture provides to address the need recorded in the Problem block.

Example: "Five prepared family dinners delivered Sunday afternoon, each ready to heat in 15 minutes."

See also: What You Offer

Solution Definition¶

The practice of describing, in specific terms, what a venture will actually provide to address a confirmed customer difficulty; the work that fills the third block of the canvas.

Example: "A single dog wash and brush-out in your driveway, Saturday mornings, $40" replaces the vague "mobile grooming."

See also: Solution Block

Solution Fit¶

How well a designed offer matches the confirmed customer difficulty and target customer, rather than what a founder personally finds exciting to build.

Example: A founder excited about a recipe app learns that parents want ready-made food, not more recipes, revealing a poor match.

Solution Iteration¶

The repeated cycle of adjusting an offer based on field evidence and then testing the adjusted version again, applying evidence-based decision making to the Solution block over several rounds.

Example: A tutor tries one-hour sessions, learns students lose focus, tests 40-minute sessions, and adjusts again based on the results.

See also: Build-Measure-Learn

Solution Pivot¶

Abandoning a current offer approach entirely in favor of a substantially different one, made when evidence shows the current direction cannot be adjusted into something that works.

Example: A founder testing a recipe app switches to delivering cooked meals after parents consistently say they have no time to cook at all.

Contrast with: Solution Refinement

Small, incremental adjustments to an offer within a cycle of changes, such as tightening scope, clarifying wording, or adding back one feature that evidence supports.

Example: After three customers ask about nail trims, Jordan adds them as a $10 add-on without changing his main service.

Contrast with: Solution Pivot

Solution Scope¶

The deliberate boundary a founder draws around what an offer will and will not include, such as which services, customers, days, or locations the first version covers.

Example: Jordan covers baths and brush-outs only, leaving haircuts and nail trims out until demand is proven.

Solution Simplicity¶

The discipline of keeping an offer's boundaries as narrow as possible without breaking its ability to resolve the customer's core difficulty.

Example: A bookkeeper launches with one package at one price instead of five tiers of services.

Solution Testing¶

The process of exposing a belief about an offer to real customer behavior to find out whether customers actually choose it, use it, and come back for more.

See also: Solution Assumption, Lean Test

Startup Budget¶

The complete financial plan listing every one-time need and its estimated price, checked against the money a founder actually has available.

Example: Priya's lists $180 for containers, $120 for kitchen time, and $50 for a food-handler certificate, against $500 in savings.

Startup Capital¶

Whatever funds a founder can access to cover one-time needs before a venture generates its own income, such as personal savings or money from a side job.

See also: Bootstrapped Funding

Startup Needs¶

The one-time resources a venture has to acquire before it can begin operating at all, such as equipment, a license, or an initial batch of supplies.

Example: Jordan's include clippers, a portable tub, and a local business license.

Contrast with: Ongoing Costs

Startup Needs Block¶

The second-to-last section of the CO.STARTERS Canvas, listing the one-time resources a venture has to acquire before it can begin operating.

Example: Jordan's entry includes clippers, a portable tub, a business license, and a pet first-aid certification.

Contrast with: Costs Block

Status Quo¶

How a customer currently lives with a difficulty overall, encompassing every option they use, ignore, or tolerate; the combined baseline any new offer has to improve on.

Example: For Jordan's customer, it is a booked-solid salon, a bottle of dry shampoo, and waiting longer between grooms.

Story-Based Messaging¶

Weaving a concrete, specific story, often the founder's own, directly into customer-facing language to make a claim memorable and believable.

Example: Jordan's post opens with his forty-minute drive to the groomer with a panting dog in the back seat.

Subscription Pricing¶

Charging a customer a fixed amount on a recurring schedule, such as weekly or monthly, in exchange for ongoing access to an offer until the customer cancels.

Example: $120 per week for five family dinners, renewing automatically each Friday.

Contrast with: One-Time Pricing

Substitute Solution¶

An option that does not resolve the exact same difficulty but satisfies enough of the same underlying need that a customer might choose it anyway.

Example: A self-service dog-wash station at the pet store plays this role against Jordan's mobile grooming.

Symptom Vs Root Cause¶

The discipline of not stopping at the first explanation a customer offers, and instead separating the visible complaint from the deeper condition producing it, since an offer aimed at the complaint alone often leaves the difficulty in place.

Example: A bakery owner hears "your bread goes stale" and learns the deeper issue is that customers shop once a week and need loaves that keep for five days.

Target Customer¶

The specific group of people a venture intends to serve first and who are most likely to buy its offer, described precisely enough that a founder could find and contact them.

Example: "Working parents at Lincoln Elementary who get home after 6 p.m." is far more useful than "families."

See also: Customer Segment, Who To Sell To

Target Market Definition¶

The finished, written sentence describing a venture's intended buyers that goes into the Customer block, produced after research has sharpened the founder's first description.

Example: "Dual-income parents at two local elementary schools who get home after 6 p.m. at least three nights a week."

Technology Resource Needs¶

Any tools, software, or equipment a venture requires to deliver its offer or run its operations, from a booking app to physical tools like clippers or a commercial oven.

Example: Priya needs insulated delivery bags and a simple online order form.

Test Hypothesis¶

The specific, falsifiable prediction a lean experiment is designed to check, stated precisely enough that the result clearly confirms or contradicts it.

Example: "At least 2 of 5 neighbors will pay a $40 deposit for a driveway session" qualifies; "people will like it" does not.

Test Result¶

The actual, factual outcome of a lean experiment, such as how many people said yes, paid, or ignored it, kept separate from any interpretation of what that outcome means.

See also: Test Result Debrief

Test Result Debrief¶

The structured reflection in which a founder reviews an experiment's outcome against the threshold set in advance and decides what it means for the canvas.

Example: Jordan sees that two of five neighbors paid, which met his threshold, so he keeps his price and plans a larger trial.

Thirty-Day Launch Plan¶

A concrete, week-by-week schedule covering the 30 days immediately after the course, translating a completed canvas into specific, dated actions rather than leaving tested ideas on a page.

Example: Priya's: week one, sign 5 families; week two, deliver the first batch; week three, collect feedback; week four, reach 10 paying families.

See also: Launch Roadmap

Tiered Pricing¶

Offering the same core solution at several price and feature levels, letting customers choose based on their own needs and budget.

Example: A tutor offers one session a week for $50, two for $90, or three for $120.

Time-Saving Pivot¶

A small adjustment to a launch plan that reduces how much founder time a step requires, without changing the venture's customer, problem, or core offer.

Example: Jordan batches driveway appointments by neighborhood to cut his driving time.

See also: Money-Saving Pivot

Transaction Revenue¶

Income collected once per discrete purchase, with no ongoing commitment from the customer to buy again, so each sale has to be earned separately.

Contrast with: Recurring Revenue

Two-Minute Pitch¶

The specific time-boxed format of the course's closing presentation, requiring a founder to distill eleven canvas blocks and a full launch plan into 120 seconds.

Example: Jordan spends 20 seconds on the problem, 30 on his offer and evidence, and the rest on his 30-day plan.

Unfair Advantage¶

A strong, hard-to-replicate edge that a rival genuinely cannot easily copy, such as an existing relationship, a proprietary process, or credibility built over years.

Example: A former school counselor starting a tutoring service already has trusted relationships with dozens of local families.

Unique Selling Point¶

The single most compelling piece of a venture's distinct value, chosen for use in marketing messages because it is both important to customers and unavailable from any alternative.

Example: Jordan's is "We come to your driveway, so there's no crate and no car ride."

Unique Value¶

The part of a venture's combined benefit-and-advantage claim that no mapped alternative can currently offer, giving customers a reason to choose it over every other option.

See also: Unique Selling Point, Differentiation

Unmet Need¶

A customer requirement that no current option, including doing nothing, adequately satisfies, whether or not the customer has ever put it into words.

Example: No local groomer offered weekend appointments at the customer's home, leaving working dog owners with nothing that fit their schedules.

See also: Market Gap

Unrefined Concept¶

A business idea that exists only as a general direction, with none of its key details, such as the specific customer, the exact offer, or the way it earns money, worked out yet.

Most participants arrive in the course with one, and that is treated as a normal starting point.

Example: "Something with mobile dog grooming" names a direction but not who pays, what they get, or how much it costs.

See also: Business Idea, Messy Idea Normalization, Draft Business Idea

Validated Concept¶

A venture idea for which accumulated evidence, especially customer payments, consistently supports the original hypothesis, giving the founder reasonable grounds to keep investing time and money in it.

Example: Priya's meal service after twelve families paid deposits and nine reordered the following week.

Contrast with: Invalid Concept

Validated Learning¶

Knowledge about a venture that a real-world test has confirmed or disproven, so it is now known with reasonable confidence, regardless of whether the result was the one the founder hoped for.

Example: If Jordan calls five neighbors and none will pay for driveway grooming, that finding still counts, because it prevents him from buying a van nobody needs.

Validation¶

The second phase of the course cycle: checking a founder's stated guesses against reality by talking to, and eventually transacting with, real people instead of assuming the guesses are correct because they feel right.

Example: Priya interviewing parents about their weeknight dinner routine before cooking a single meal for sale is this phase in practice.

See also: Clarity, Action, Lean Validation

Validation Milestone¶

A specific, predefined point at which enough evidence has accumulated to make a confident call about a venture idea, rather than continuing to test indefinitely out of hesitation.

Example: Priya sets hers at "ten paying families for two consecutive weeks."

Validation Test Design¶

The advance planning of exactly what a lean experiment will measure and what result will count as a "yes" or a "no," decided beforehand so the outcome cannot be reinterpreted afterward.

Example: Before posting, Priya decides that at least three paid deposits from 20 responses will count as success.

See also: Test Hypothesis

Value Clarity¶

The property of a benefit-and-advantage statement being understandable on a single read, with no jargon a target customer would not use themselves.

See also: Message Clarity

Value Delivery¶

The mechanism by which a customer actually receives the outcome an offer promises, meaning how, when, and where it is concretely handed over, not just what is described in marketing.

See also: Offer Design

Value Differentiation¶

How clearly a benefit-and-advantage statement sets an offer apart from every mapped alternative, so it could not just as easily describe a rival.

Example: "Quality grooming you can trust" fails because any groomer could say it; "grooming in your driveway on Saturday mornings" passes.

Value Proposition¶

The combined, specific answer to two questions, why the customer wants this solution and why this founder is the right one to deliver it, stated together as a single coherent claim.

Example: "Working parents get a week of healthy dinners delivered Sunday, from a mom who has lived the 6 p.m. scramble herself."

See also: Value Statement, One-Sentence Value Proposition

The ongoing process of tightening a benefit-and-advantage statement as new field evidence arrives, such as adopting customers' own words or strengthening the stated advantage.

Example: After hearing parents say "the 6 p.m. scramble" again and again, Priya puts that exact phrase into her statement.

Value Statement¶

A single concise sentence combining a venture's benefit and advantage into one claim, often in the pattern "[customer] gets [core benefit] because [founder advantage], unlike [main alternative]."

Example: "Busy dog owners get a clean, calm dog without leaving home, because a former vet tech comes to them, unlike salons with two-week waits."

Value-Based Pricing¶

Setting a price according to how much value the customer believes they receive, rather than according to what the offer costs to deliver.

Example: A bookkeeper charges $200 a month because clients avoid late-filing penalties and hours of stress that are worth far more to them.

Contrast with: Cost-Plus Pricing

Variable Costs¶

Expenses that rise and fall directly with how much a venture sells, such as supplies used per sale, packaging per order, or fuel per delivery.

Example: Every additional family Priya serves adds groceries and containers to her weekly bill.

Contrast with: Fixed Costs

Virtual Learning Lab¶

A course format delivered entirely online that keeps the behavior of a hands-on workshop, combining live, synchronous instruction with structured group exercises over video conferencing rather than recorded lectures.

See also: Cohort-Based Learning, Canvas Sprint

Weak Assumption¶

A canvas belief that interview evidence only partially supports, or supports inconsistently across different customers; not disproven outright, but not solid either.

Example: Two of five owners would pay $40, but three said $30 was their limit.

Weekly Milestone¶

A specific, meaningful checkpoint a plan aims to reach by the end of a given seven-day period, stated as a concrete marker rather than a vague hope.

Example: "Ten households contacted" for week one and "first paid booking confirmed" for week two.

See also: Weekly Target

Weekly Target¶

The specific number attached to a checkpoint for a given seven-day period, set in advance so progress can be checked objectively rather than by feeling.

See also: Weekly Milestone

What To Sell¶

The element of the 30-day plan that restates the minimum testable iteration as a concrete, purchasable offer for the next 30 days, rather than the eventual full vision.

Example: Priya's: "Five family dinners delivered Sunday, $120 per week."

See also: Who To Sell To, How To Reach Them

What You Offer¶

The plain-language question the Solution block of the CO.STARTERS Canvas asks a founder to answer: the specific product or service a customer actually receives.

See also: Solution Block

Who To Sell To¶

The element of the 30-day plan that restates the target customer as a specific, findable group of people to pursue during those 30 days.

Example: Jordan's: "Dog owners in the Maple Grove neighborhood app group."

Who You Serve¶

The plain-language question the Customer block of the CO.STARTERS Canvas asks a founder to answer, naming the specific people a venture exists to help.

See also: Customer Block, Customer Definition

Why Customer Wants It¶

The question the Benefit block asks: what specific positive outcome a target customer experiences by choosing an offer, expressed in terms of their life rather than product features.

See also: Benefit Block, Customer Benefit

Why You Solve The Problem¶

The question the Advantage block asks: why this specific founder, rather than anyone else, is positioned to deliver a solution well, as distinct from why the solution itself is good.

See also: Advantage Block, Founder Advantage

Willingness To Pay¶

The actual maximum amount a specific customer would hand over for a specific offer, discoverable through real buying behavior rather than survey answers.

Example: Parents who say they would pay $150 a week may, in practice, stop ordering once the price goes above $110.

Willingness To Solve¶

Whether a customer is actually motivated to spend money, time, or effort addressing a difficulty, as distinct from merely being bothered by it.

Many real problems are quietly tolerated for years.

Example: Asked "What have you already tried or paid for to fix this?", a dog owner who answers "nothing" may be irritated but not motivated to act.

See also: Essential Bills Priority, Willingness To Pay

Wins And Lessons Review¶

A structured weekly reflection, ideally shared with cohort peers, that names what worked, what did not, and what changes for the next week.

Example: Jordan's Friday note: "Win: three bookings. Lesson: flyers got zero replies. Change: drop flyers and post twice in the app."

See also: Setback Normalization

Word Of Mouth¶

The route by which satisfied customers tell others about a venture without being deliberately prompted or rewarded to do so.

Example: A parent mentions Priya's meals to two friends at soccer practice, and both sign up.

Contrast with: Referral Channel
