Product-User Fit Comes Before Product-Market Fit

Peter Lauten and David Ulevitch · Andreessen Horowitz (a16z) Free Intermediate

A useful correction for founders chasing a market-wide 40 percent before a single cohort loves the product. The authors argue you first need a small group of power users who genuinely pull the product out of your hands, then expand outward. It sharpens the difference between broad lukewarm interest and the intense fit that actually compounds.

  • Win one delighted user segment before chasing the whole market
  • Intense love from a few beats mild interest from many
  • Expand outward from a strong core, not from a broad thin base
