Measuring Product Market Fit
refoundai/lenny-skillsEvery product founder wants to know if their product truly fits the market. Product-market fit is the moment when customers really want what you built. This skill helps you measure that fit using proven methods from top product leaders.
You can use the Sean Ellis survey to ask customers how they would feel if your product disappeared. If 40% say they would be very disappointed, you are on the right track. Retention is another key sign. If users keep coming back, you are creating real value.
The skill guides you through different stages of fit. It helps you decide whether to scale or keep improving. You will learn to look for customer pull and avoid confusing vanity metrics with real signals.
