Product-Market Fit
What Is Product-Market Fit?
Product-Market Fit is the point where your product consistently solves a clear problem for a defined customer segment, resulting in repeatable usage, retention, and organic pull. In B2B, PMF is visible in behavior, not opinions.
For B2B SaaS, PMF is not a one-time milestone. It evolves with each segment you penetrate. Use these three signals:
- Retention Strength
Customers stay without being chased. - Expansion Pull
Upsell happens because customers ask for more. - Pipeline Efficiency
Deals in your core ICP close faster and with fewer objections.
PMF is fragile. Many startups “lose” PMF after scaling the wrong segment.
“PMF isn’t a survey metric. It’s a behavioral truth. When PMF is real, sales feels easier and marketing feels obvious.”
