Pmf Strategy

Guides you through validating product-market fit before you scale, covering the Sean Ellis 40% test (measuring how many users would be "very disappointed" without your product), the painkiller vs vitamin framework, and retention signals. Use this when you're trying to figure out if you actually have PMF or just polite feedback, when planning measurement surveys, or diagnosing why traction isn't happening. The core insight here is solid: 99% of startups fail from PMF issues, usually by solving nice-to-haves instead of urgent pain or by scaling acquisition too early. It treats PMF as continuous validation rather than a one-time milestone, which reflects how markets actually work.
