Q: What is the 40% PMF threshold?

Analysis of hundreds of startups found that companies with 40% or more of users saying they would be "very disappointed" without the product reliably achieve sustainable growth. Below 40%, word-of-mouth rarely compounds. Above it, acquisition costs tend to fall and retention improves. Superhuman famously used this threshold to guide their early product decisions.

Q: Can AI agents deploy Canviq PMF surveys?

Yes. Canviq exposes an MCP (Model Context Protocol) server that enables Claude, ChatGPT, and other AI agents to deploy surveys, query PMF scores, and trigger workflows programmatically using natural language — without opening a UI.

Question 1

What is PMF survey software?

Accepted Answer

PMF survey software helps SaaS founders measure product-market fit by deploying the PMF survey question ("How would you feel if you could no longer use this product?") to active users and tracking the percentage who answer "very disappointed." A score above 40% is the widely accepted PMF threshold.

Question 2

What is the PMF survey?

Accepted Answer

The PMF survey is a 4-question instrument that asks users how disappointed they would be if the product disappeared, what kind of person the product is built for, what the main benefit is, and what could be improved. The percentage who answer "very disappointed" to the first question is your PMF score. Companies above 40% have reliably found product-market fit.

Question 3

How does Canviq deploy PMF surveys?

Accepted Answer

Canviq deploys surveys via a JavaScript SDK (<50KB) embedded in your web or mobile app, an in-app widget, or an email link. Smart targeting ensures only users who have engaged with the product at least twice in the last 14 days receive the survey — the engagement threshold the PMF survey methodology recommends for valid signal.
