A reference you can use while doing the work
We went through the pain of this so you don’t have to. Here is the plain-English version, with a practical example for every term.
A new idea brings unfamiliar language along with it. You do not need an investor’s vocabulary to make progress. You need to know what you are testing, what customers actually do, and whether the business can keep delivering value. This guide turns the most useful terms into decisions you can practice.
About the numbers: these are hypothetical teaching examples, not business results or recommended targets. Dollar amounts use USD for illustration.
1. Turn an idea into a testable offer
ICP — ideal customer profile
The customer situation most likely to fit the problem you solve, including constraints and buying context.
Example: Your scheduling tool starts with mobile dog groomers managing repeat clients, rather than every business with a calendar.
Customer problem
A specific difficulty or unmet goal, grounded in observation rather than your preferred solution.
Example: Three groomers describe losing bookings when appointments change. That is clearer evidence than saying they “need AI.”
Value proposition
The useful change a particular customer can expect, and why your approach is relevant.
Example: “Keep repeat grooming appointments organized in one place” explains a benefit; “an innovative platform” does not.
Hypothesis
A claim you can test through observable evidence.
Example: “At least three of ten relevant owners will pay for a manually delivered scheduling cleanup” can be tested; “everyone will love it” cannot.
MVP — minimum viable product
The smallest usable offer that tests an important assumption. It still needs to deliver what you promise.
Example: A paid, manually prepared weekly schedule can test the need before you build a complete scheduling app.
Validation
Evidence that reduces uncertainty about a specific assumption. It is not a permanent stamp of success.
Example: Three buyers paying for a pilot support willingness to pay in that small group; they do not prove national demand.
Product-market fit
A strong match between an offer and a market, evidenced through sustained demand and value. No single survey or ratio proves it.
Example: Repeated use, renewals and unsolicited referrals across several cohorts are stronger signals than launch-day curiosity.
Opportunity cost
The value of the best alternative you give up by choosing an activity.
Example: Ten hours polishing a logo means ten hours unavailable for buyer interviews or paid delivery. Compare the likely learning and value.
2. Follow people from signup to value
Funnel
A defined sequence of customer actions with counts at each stage. State eligibility and time windows.
Example: Of 100 eligible signups, 40 publish a first useful schedule and 24 of those return the next week.
Conversion rate
The share of a defined eligible group completing a specified action in a period.
Example: Eight purchases ÷ 200 eligible visits = 4% visit-to-purchase conversion. Account conversion would use a different denominator.
Activation
A first meaningful behavior that indicates the customer experienced value. A signup alone may not do that.
Example: For a scheduling tool, activation could mean creating and using a first schedule within seven days.
Time to value
Elapsed time from a defined starting point to a first useful outcome.
Example: A new user signs up Monday at noon and shares a usable schedule Tuesday at noon: 24 hours to first value.
Cohort
A group sharing a starting event or trait, tracked consistently over time.
Example: Compare October signups at 30 days with November signups once they also reach 30 days—not while they are only five days old.
Retention
The share of a starting cohort that returns or remains active under a defined rule.
Example: Twenty-four of 40 activated users use the schedule during week two: 60% week-two retention among activated users.
Churn
The loss of customers or recurring revenue over a stated period. Customer churn and revenue churn are different.
Example: Five of 100 starting subscribers cancel in a month: 5% customer churn, excluding new subscribers.
North Star metric
A central measure intended to represent recurring customer value. It needs supporting measures and guardrails.
Example: Weekly schedules actually used by customers is closer to value than total accounts, but errors and cancellation rates still matter.
3. Understand the economics and the cash
Revenue
Income earned from the offer, distinct from cash collected, transaction volume or signed commitments.
Example: Ten delivered $100 service packages generate $1,000 revenue; an unpaid invoice affects collection timing.
Gross margin
Revenue less cost of goods or services, divided by revenue. Define your accounting cost categories.
Example: $1,000 revenue minus $400 cost of delivery leaves $600 gross profit: 60% gross margin.
Contribution margin
Revenue less costs that vary with serving the customer. Label whether acquisition is included.
Example: $100 subscription revenue less $30 variable service and payment costs leaves $70 contribution before acquisition and fixed costs.
CAC — customer acquisition cost
Sales and marketing acquisition costs divided by new customers, with a consistent cost scope and period.
Example: $900 of acquisition effort and spending ÷ 15 new customers = $60 CAC.
LTV — customer lifetime value
An estimate of revenue or contribution over a customer relationship. Name the version, horizon and assumptions.
Example: $100 average order × three orders a year × two assumed years = $600 revenue LTV. At 40% contribution, modeled contribution LTV is $240.
LTV:CAC and payback
LTV:CAC compares modeled customer value with acquisition cost; payback asks when cumulative contribution covers that cost.
Example: $240 contribution LTV ÷ $60 CAC = 4×. If each order contributes $40, acquisition is covered during the second order—not automatically after one month.
MRR and ARR
MRR is normalized monthly recurring revenue; ARR annualizes eligible recurring revenue. Exclude one-off sales.
Example: Twenty subscribers paying $25 monthly = $500 MRR and $6,000 annualized ARR, before churn and changes.
Net burn and cash runway
Net burn is monthly cash outflow above cash inflow. Runway estimates how long available cash lasts at that burn.
Example: $30,000 available cash ÷ $5,000 monthly net burn = six months, assuming the burn stays constant and all cash is available.
4. Choose tools that support the work
CRM
A customer-record system and operating process for managing conversations, ownership and follow-up.
Example: A pilot buyer has one record containing their need, trial notes, payment status and next check-in.
Integration
A connection that moves or coordinates information between tools. Compatibility includes the specific action, not just two familiar logos.
Example: Your booking form creates one CRM record with the requested service and source, and updates it when the booking changes.
API and webhook
An API lets software request an action or data; a webhook notifies another system that an event happened.
Example: A payment event triggers a webhook; your workflow checks it and calls an API to grant the purchased access once.
Automation
A configured process that runs when defined conditions are met.
Example: After a confirmed purchase, a workflow creates a delivery task. A failed payment does not trigger that task.
AI agent
An AI system that can choose and perform steps with permitted tools toward a goal. Define its permissions and completion check.
Example: An agent compares three app listings and drafts a recommendation. You verify fit and authorize any installation.
TCO — total cost of ownership
Fees plus setup, usage, training, maintenance and exit costs over a chosen period.
Example: A $20 monthly app with $180 setup costs $420 over the first year before usage fees, rather than just $240.

Use an app marketplace to fill one real gap
An app marketplace is a directory of extensions for a particular platform. It can help you add a missing capability to your current site or workflow. Start with the customer’s stuck step and the metric you expect to change, then search for the capability.
| Need | What to investigate |
|---|---|
| A paid pilot needs booking, payment and delivery to connect | Search for the missing step before commissioning a rebuild. Confirm that the connector supports the exact event, fields and plan you use. |
| Where to look | Start with your platform’s own marketplace: WordPress plugins, the Shopify App Store, or your CRM’s integration directory. Use Zapier’s app directory to investigate cross-tool workflows. |
- Name the job. Write one sentence: “When this event happens, this person needs this useful next step.” Check whether your current plan already supports it.
- Compare two or three candidates. Check the required plan, current fees and usage limits, recent maintenance, support, permissions, supported data fields and cancellation terms.
- Calculate the full cost. Include setup and maintenance. A $60 monthly app needs three genuinely additional sales at $20 contribution per sale to cover its fee. With $120 setup, the first month needs nine such sales. Sales merely credited to the app are not necessarily additional.
- Test a complete journey. Use a safe test account or draft environment. Check success, failure, cancellation and duplicate events; verify mobile behavior and what happens after uninstalling.
- Keep or remove it on evidence. Record a baseline, an owner and a review date. Measure contribution, reliability or usable time saved. Hours freed are capacity until you actually turn them into value.
Directory links are ordinary official links. Availability, compatibility and pricing can change; verify the listing before installing. An app recommendation should explain fit and trade-offs rather than treating every popular extension as essential.
Give an AI agent a useful, reviewable job
Ask an agent to reconcile definitions, check arithmetic, research app capabilities, classify anonymized feedback or draft a weekly review. Provide the source records and your cost definitions. Keep purchases, live installations, customer messages and budget changes subject to the permissions you explicitly grant.
Using only the evidence I supply, create a one-page founder scorecard. Define the customer, first-value event, activation window, cohort, acquisition cost and contribution calculation. Mark unknown values as unknown. Suggest the smallest test of the weakest assumption and explain what result would change the decision. Do not invent customer demand.
Check the result against the original records. A polished explanation is not proof that the data is complete or that the proposed change will work.
Put five terms to work this week
- Choose one decision. What are you trying to improve or learn?
- Select five measures at most. Define the event, denominator, time window, costs and source for each.
- Calculate one real example. Reconcile it with an order, customer, invoice or observed task.
- Make one bounded change. Record the hypothesis, owner, cost limit and review date.
- Review the evidence. Continue, revise or stop. Record uncertainty and customer feedback alongside the numbers.
Choose one assumption, one customer group, and one observable next step. Bring that brief into Waymaker, or use the free First Experiment Planner to turn it into a small test. For a real enquiry, continue with scoping the next step.
