Frameworks

Product-market fit frameworks

A working library of the thinking tools that get startups to product-market fit. Not academic summaries, each one covers what it is, when to reach for it, and how to actually apply it, then connects back to the one number that tells you if it worked. Start with your PMF score, or measure it free with the PMF calculator.
