Product-Market Fit Measurement

Systematically measure, diagnose, and improve product-market fit using quantitative metrics and qualitative signals.

When to Use

• Wondering if you've achieved product-market fit
• Preparing for fundraising (investors will ask about PMF)
• Deciding whether to scale or pivot
• Diagnosing why growth has stalled
• Prioritizing feature work (fix retention vs. add features)
• Setting team goals and OKRs around PMF

Core Concept

PMF is not binary - it's a spectrum from "no PMF" to "strong PMF". Most products exist somewhere in between.

Key Insight: PMF is dynamic, not static. You can lose it as markets shift, competitors emerge, or user expectations evolve.
