Product-Market Fit

Product-market fit (PMF) is the point where your retention curve flattens, word-of-mouth grows faster than your CAC, and pipeline starts generating itself. Finding product market fit isn't a single moment. It's a series of signals that tighten or loosen as you move from early adopters into a broader market. Measuring PMF is where most teams go fuzzy: they lean on NPS or survey responses instead of cohort retention, revenue expansion, and real pull from the market.

The posts here get specific about how to find PMF, how to tell when you have it versus when you're fooling yourself with enthusiast adoption, and what it takes to hold onto it as you scale. You'll find frameworks for measuring PMF with actual data, teardowns of companies that had it and lost it by moving upmarket too fast, and analysis of what real retention curves look like when PMF is present. Treat it as a diagnostic toolkit, not a checklist.
