4 Critical PMF Validation Pitfalls to Avoid

Learn from common mistakes that prevent startups from achieving true product-market fit.

Vanity Metrics Focus

Focusing on metrics that look good but don't indicate real PMF

Warning:
Downloads, signups, and page views don't equal product-market fit
Solution:
Focus on engagement, retention, and revenue metrics instead

Confirmation Bias

Only seeking feedback that confirms your assumptions

Warning:
Asking leading questions or only talking to supporters
Solution:
Actively seek disconfirming evidence and critical feedback

Premature Scaling

Scaling marketing and sales before achieving PMF

Warning:
Burning cash on customer acquisition for a product people don't love
Solution:
Achieve clear PMF signals before investing in growth

Feature Creep

Adding features instead of improving core value proposition

Warning:
More features won't fix a fundamental product-market mismatch
Solution:
Double down on core value and perfect the main use case
