& Product-Market
Fit
Find the customers worth pursuing. Size the opportunity you can serve. Test whether your solution delivers a benefit they will pay for and keep choosing.
01 / Find the opportunity
Before you ship it, will someone buy it?
Engineering hours add up. Technical debt grows. The launch date gets closer.
What evidence shows customers need what you’re building enough to pay for it?
Internal enthusiasm can move a product onto the roadmap before anyone validates the problem, buyer, or market fit.
Work backward from the customer:
- Understand the need: What problem matters enough to change behavior and fund a solution?
- Size the opportunity: Who can you serve, reach, and realistically win? Use TAM → SAM → SOM.
- Test the fit: Do customers choose your solution, experience meaningful value, and keep choosing it?
Use this playbook to connect customer research, ICP development, and market evidence to your next product or growth decision.
The evidence / Capacity · Adoption · Buying progress
Three reasons to validate the next commitment.
Separate studies highlight pressure on development time, concentration of feature use, and friction in business buying. AMG’s application: investigate customer priorities and buying conditions before expanding a product or growth commitment.
50% lose 10+ hours a week
In Atlassian’s 2025 research, half of developers reported losing at least 10 hours weekly to inefficiencies, largely organizational.
Decision to support: Prioritize work against a documented customer problem and intended outcome before committing scarce engineering capacity.
Atlassian, State of Developer Experience, 2025. Survey of 3,500 developers and managers across six countries. This measures broader inefficiency, not time spent specifically building unwanted products.
6.4% drive 80% of clicks
Pendo’s 2024 feature-adoption benchmark reported that, at the median, 6.4% of features generated 80% of click volume.
Decision to support: Combine usage patterns with customer interviews and outcomes to understand which capabilities deserve investment.
Pendo, feature-adoption benchmarking, July 1, 2024. A click-concentration measure within its benchmarked products. Lower click frequency alone does not establish that a feature lacks value or that a product lacks market fit.
86% of purchases stall
Forrester’s 2024 research reported that 86% of B2B purchases stalled during the buying process.
Decision to support: Research the buying group, business priority, approval path and evidence customers need to progress.
Forrester, The State of Business Buying, December 4, 2024. Covers B2B buying broadly. A stall is not necessarily a lost purchase, and the finding does not identify lack of product-market fit as the cause of every delay.
Read each finding in its own context; the studies use different populations and methods. The decision guidance above is AMG’s interpretation. These figures establish neither an AMG performance claim nor a guaranteed result from customer research. Sources reviewed October 23, 2026.
02 / Size the opportunity
TAM → SAM → SOM: make each boundary defensible.
| Layer | The decision it supports | How to build the estimate |
|---|---|---|
| TAM · Total Addressable Market | How much demand could exist for this defined category of solution? | Estimate all potential purchasing accounts with the relevant need × plausible annual spend per account. Define the category and problem before counting companies. |
| SAM · Serviceable Available Market | Which portion can our current offer and operating model actually serve? | Filter TAM by use case, geography, company conditions, technical requirements, language, delivery and purchasing constraints. |
| SOM · Serviceable Obtainable Market | What portion can we realistically capture within a stated timeframe? | Constrain SAM by customer demand, competitive alternatives, account access, conversion evidence, sales-cycle timing and delivery capacity. |
Count distinct purchasing entities, not every employee, contact or location as a separate customer unless each is a distinct buying unit. For multi-location or seat-based pricing, separate the account count from the pricing driver. Avoid overlapping segments and double counting.
Build from the bottom up: document account counts and filters using dated sources such as official business statistics, industry directories and your own customer records. Use category reports as a reasonableness check. Record coverage gaps and pricing uncertainty rather than converting an industry headline into your revenue forecast.
Do not choose SOM as an arbitrary market-share percentage. A reachable account list still needs a credible path to paid customers. Calculate low, base and high scenarios, state what would change them, and distinguish new annual bookings from year-end recurring revenue or revenue recognized during the year.
03 / Connect market sizing to ICP research
Use evidence to decide where you have the strongest right to win.
Your ideal customer profile describes company conditions associated with a strong match. It is more useful than a broad industry label or an executive job title. Compare segments on problem urgency, ability to benefit, budget access, buying friction, implementation fit and the ability to reach them.
| Research layer | Questions to investigate | Evidence to record |
|---|---|---|
| Company fit | Which operating conditions make the problem costly and our solution deliverable? What excludes an account? | Recent customer outcomes, failed implementations, company conditions, observed constraints and contrary examples. |
| User | What job needs to get easier? What workflow change or adoption burden does the solution introduce? | Observed use, time to first value, workflow interviews, repeated use and support needs. |
| Buyer / evaluation owner | What must the solution satisfy to be selected and implemented? | Evaluation criteria, alternatives, integration requirements, purchasing process and implementation effort. |
| KDM / approval authority | Who can authorize the spend or accept the risk? What outcome makes that decision defensible? | Confirmed decision rights, budget ownership, business case, evidence standards and approval conditions. |
One person may hold several roles. A title does not confirm authority. Include champions, procurement and implementation owners where relevant. Ask about recent real decisions: “What happened last time?”, “What did the delay cost?”, “What alternative did you choose?” and “Who had to agree?”
Keep the research honest: include won, lost, retained, churned and no-decision accounts where available. Separate customer statements from observed behavior and analyst assumptions. Record disagreements, missing voices and evidence that would disprove your preferred segment.
Turn the strongest recurring patterns into a dated ICP hypothesis and a role-specific benefit and proof brief. Use the ICP, Positioning & Messaging Playbook to develop it with Marketing, Sales, Product and Customer Success.
04 / Worked example
Show the market math, then test the assumptions.
Illustrative B2B software scenario. All counts, prices, rates and customer observations below are invented to demonstrate the method. They are not market research, benchmarks or AMG client results.
A workflow platform hypothesizes that multi-location service businesses need fewer delays in location-opening approvals. Assume one annual buying account per company and an annual contract value of $12,000.
- TAM: 20,000 potentially relevant purchasing companies × $12,000 = $240 million in annual contract-value potential.
- SAM: 2,000 of those companies meet the present territory, workflow, technical and support constraints × $12,000 = $24 million.
- 12-month new-business SOM scenario: the team can meaningfully work 240 distinct accounts. Assume 25% become accepted opportunities and 20% of those win: 240 × 25% × 20% = 12 new customers.
- Capacity and timing: implementation can support 15 new customers, so the modeled 12 fit that ceiling. Confirm enough time remains for evaluation, procurement and onboarding.
- Modeled capture: 12 × $12,000 = $144,000 in new annual contract bookings, or 0.6% of the illustrated SAM. The percentage follows the operating assumptions; it does not justify them.
| Opportunity win rate | Modeled new customers | Annual contract bookings |
|---|---|---|
| 10% | 6 | $72,000 |
| 20% | 12 | $144,000 |
| 25% | 15 | $180,000 |
These are planning scenarios, not commitments. The example still needs verified account counts, price validation, representative opportunity cohorts and delivery evidence. Annual bookings do not equal cash collected or revenue recognized in that year. Use the Pipeline Planner to translate the chosen scenario into meetings, accepted opportunities, timing and investment.
05 / Evaluate product-market fit
Look for a segment that gets value and keeps choosing you.
Product-market fit concerns the match between an offer and meaningful demand in a specific market. Evaluate whether customers obtain the promised improvement, choose the offer at workable pricing, and continue using, renewing or repurchasing it in a way appropriate to the product. An enthusiastic interview, funding round, large TAM or one successful launch does not establish fit.
| Evidence dimension | Useful signal | What may mislead you |
|---|---|---|
| Problem urgency | Customers describe a recurring costly problem and take action to resolve it. | Polite interest, hypothetical purchase intent or feedback only from friendly contacts. |
| Payment and choice | Comparable buyers choose and pay for the offer, with a documented reason to switch. | Free trials, heavy discounts or bespoke founder effort mistaken for repeatable demand. |
| Customer outcome | Users reach the intended benefit; the baseline, timeframe and conditions are recorded. | Feature clicks without evidence that the customer’s job improves. |
| Continued value | Cohorts retain, renew, expand or repurchase at the expected usage or purchase interval. | Aggregate growth masking churn, or annual contracts too young to show renewal behavior. |
| Repeatable delivery | The team can reproduce the result for similar customers with understood effort and economics. | A few unusually supported accounts treated as evidence that every segment will work. |
Return to the illustrative platform: suppose eight customers run a pilot and five continue paying. That is useful evidence to examine, but a small selected cohort cannot establish market-wide PMF. Which five continued, what outcome did they achieve, what happened to the other three, and can the team repeat delivery without exceptional support? A renewed contract may support the business case while user-level adoption remains weak; investigate both.
Use comparable cohorts and adequate observation time. Durable equipment and one-time services need evidence of successful outcomes, recommendation and repeat choice where applicable; daily engagement is not the right test for every business. Select success measures and a decision date before the test. Reassess fit when pricing, product, customer segment or market conditions change.
06 / Make the next decision
Let the weak assumption determine the next move.
The market is large, but demand is unclear
Narrow the segment and investigate recent buying behavior, alternatives and problem urgency. Run a bounded offer test before expanding spend.
Customers buy, but do not experience value
Examine expectation, implementation, activation and product capability. Use the Launch & Adoption Playbook to define first value and who owns it.
One segment retains; another churns
Separate the evidence by segment. Update the ICP, exclusions and serviceable market instead of blending the results into a reassuring average.
Value is repeatable, but capacity limits growth
Model acquisition and delivery capacity, then fund the constraint. If entering a new territory, revalidate local SAM and fit using the Regional GTM Playbook.

08 / Research notes
Separate external guidance from your own evidence.
This page combines AMG’s planning method with established customer-research and PMF principles. The U.S. Small Business Administration’s market research guidance outlines questions about demand, market size, location, alternatives and pricing. Y Combinator’s “The Real Product Market Fit” emphasizes meaningful customer problems, customer conversations and iteration. Neither source supplies the figures in our illustrative example.
Sources reviewed October 23, 2026. Market-sizing estimates and PMF assessments require evidence specific to your offer and segment. No universal percentage, survey score or checklist result establishes fit for every business.
