The 4 Stages of PMF Journey

Where are you on the path to product-market fit?

Stage 1

Pre-PMF

You're still searching. Users churn quickly, no organic growth.

Focus on talking to users, not building features
Stage 2

Early PMF

A small group loves your product. Retention is improving.

Double down on what works for that group
Stage 3

Strong PMF

40%+ would be very disappointed. Organic referrals happening.

Time to scale marketing and sales
Stage 4

Scaling

PMF proven. Focus shifts to growth and unit economics.

Optimize CAC/LTV, hire team, raise funding

Common PMF Mistakes

Confusing early traction with PMF
Scaling before achieving PMF
Building features instead of talking to users
Ignoring churn signals
Measuring vanity metrics (downloads, signups)
Not segmenting user feedback by persona
