How to Measure Product-Market Fit
Combine customer survey evidence with retention and usage to assess whether a product serves a durable need.
The Short Version
Combine customer survey evidence with retention and usage to assess whether a product serves a durable need. A practical way to begin is to define the target user and core use case, then survey active and recently inactive users separately. Finish by making sure you treat the result as a body of evidence rather than one threshold score. The full walkthrough below explains each part in order.
