How to Measure Product Market Fit
First Round Review Free Intermediate
The practical guide to telling real fit apart from polite interest, which is the exact skill a first-time student founder lacks. It walks through behavioural signals (repeat use, willingness to pay, the Sean Ellis survey) so you do not mistake friends being nice for a market that truly needs you. Use it to keep yourself honest about whether your access to a market is turning into real demand.
- Real fit shows up as behaviour, retention, and payment, not applause.
- The 'how disappointed if you lost this' survey is a usable early gauge.
- External hype is not evidence of fit, buying and returning is.
