Measuring Product-Market Fit

The Product-Market Fit (PMF) survey is one of Formbricks' most popular templates. Based on Sean Ellis' methodology, it measures how essential your product is to your users by asking a single core question: "How disappointed would you be if you could no longer use [product]?"

The PMF Framework

The survey asks users to choose from three responses:

• Very disappointed — These are your power users who depend on your product
• Somewhat disappointed — Users who see value but could find alternatives
• Not disappointed — Users who have not found meaningful value

The benchmark for product-market fit is when 40% or more of respondents say they would be "very disappointed." Below that threshold, your product likely needs further iteration to find its core value proposition.

Using the Template

Click Try this template [1] on the best practices page to preview the survey and see the question flow. The right panel shows a live preview of how the survey appears to users — click Restart [2] to replay the survey experience.

The template includes:

• The core PMF question
• A follow-up asking what the primary benefit of the product is
• An open-ended question about how the product could be improved
• A classification question about the user's role or use case

When to Deploy

Send the PMF survey to users who have had meaningful exposure to your product — typically after 2-4 weeks of active use. Avoid surveying users who signed up recently, as they have not had enough time to form a genuine assessment.

Analyzing Results

Formbricks aggregates responses into a dashboard showing the percentage breakdown across the three categories. Track this metric over time to measure whether product changes are moving the needle toward the 40% threshold.
