Validation framework
How to validate a startup idea before you build
Most failed products were never tested against the market. This five-step process replaces gut feel with evidence — and it takes days, not months.
1. Prove the problem exists
An idea is only as strong as the pain it solves. Look for evidence that people already spend money or time on workarounds: forum threads, support tickets, spreadsheet hacks, expensive consultants. If nobody is struggling visibly, the problem may be too mild to build a business on.
2. Size the market honestly
Estimate how many buyers exist and what they spend today. Combine top-down sources (census data, industry reports) with a bottom-up count (number of target customers × realistic price). A market that is too small caps your ceiling; one that is huge but crowded raises the bar for differentiation.
3. Map the competitors — including "doing nothing"
List direct competitors, indirect alternatives, and the status quo. For each, note pricing, target customer, and the complaint their users repeat in reviews. Your edge usually lives in those repeated complaints. No competitors at all is a warning sign, not a green light.
4. Test willingness to pay
Interest is free; payment is evidence. Run a pricing-lab test: ask target customers what they would consider cheap, expensive, and too expensive for the outcome you promise, or try to pre-sell before building. The spread between "cheap" and "too expensive" is your pricing corridor.
5. Make a verdict — and write it down
Score each dimension, then decide: build, validate more, reposition, or drop. Writing the verdict down forces honesty and gives you a baseline to compare against when new evidence arrives. Marketproof automates exactly this loop: guided scorecard, live competitor research, cited market data, and a pricing lab in one report.
