PMF Survey (Product-Market Fit Survey)

What It Is

The PMF Survey is a method to measure and systematically improve product-market fit. The core insight: you can put a number on product-market fit, and you can use that number to write your roadmap.

The key question: "How would you feel if you could no longer use this product?"

Very disappointed - "I'd be devastated. I need this."
Somewhat disappointed - "I'd be bummed but I'd find something else."
Not disappointed - "I wouldn't really care."

Sean Ellis discovered that companies with 40% or more "very disappointed" responses almost always grew successfully, while those under 40% struggled. This benchmark has held across thousands of companies.

Rahul Vohra at Superhuman took this further: he built an engine that uses survey responses to algorithmically generate a roadmap guaranteed to increase PMF score.

When to Use It

Use the PMF Survey when you need to:

Quantify product-market fit before making major investment decisions
Decide whether to pivot or double down
Prioritize your roadmap based on what will actually move the needle
Identify your best customer segment (who loves you most)
Track PMF over time as you iterate
Make the case to investors with data, not gut feeling

When Not to Use It

You have fewer than 30 active users (sample too small)
Users haven't had enough time to experience value (survey too early)
The product is employer-mandated (users had no choice)
You want to validate a hypothesis without building (use JTBD instead)
