The problem
Most startups fail because nobody needs them.

of tech startups scale prematurely
Startup Genome's data: hiring and spending on growth before fit is proven. Burning runway to fill a leaky bucket.

Start Tracking PMFThe methodology
We didn't invent the method.
We built its instrument.
PMFtracker didn't invent the product-market fit survey. We automated the one these operators and investors publicly champion. Here's what they say about the method behind it.
"The insights we gained from the Product Market Fit Survey in 2008 at Dropbox and Eventbrite were incredibly helpful for figuring out how to deliver the right experiences to the right customers."
"It's hard to overstate the impact of this product-market fit engine on our company. Everything we do at Superhuman, from hiring to selling and marketing to raising capital, has become significantly easier."
"The Sean Ellis score is a key element of how Nubank measures product-market fit and makes decisions about investing in new products."
"Back in April, we ran this very survey. In total, we got 138 responses. The feedback we received in the open-ended text fields has driven a lot of upcoming product features and improvements."
"I've trained 300+ startups on this exact method. PMFtracker is the tool I always wished they had."Olek Uznanski, Founder of PMFtracker

FAQ
Fair questions.
How is the PMF score calculated?
One question: "How would you feel if you could no longer use this product?" The share of engaged users answering "very disappointed" is your score. N/A answers from churned users are dropped so they never distort the result. 40% or more is the benchmark for product-market fit.
What's a good PMF score?
40% is the line, drawn from Sean Ellis's benchmarking of roughly 100 startups. Slack measured 51%. Superhuman started at 22% and worked it to 58%. Below 40% isn't a verdict, it's a baseline to improve from.
Who should I survey?
Engaged users only: people who have used the core product recently, ideally at least twice. Surveying your whole list pollutes the score with people who were never going to care. PMFtracker targets engaged users automatically.
How many responses do I need?
40 valid responses gives a directional read. 100+ makes it reliable enough for investors. The confidence band in your dashboard shows exactly how much to trust the number at every sample size.
Is it really a one-time payment?
Yes. Pay once, own it forever. No subscription, no recurring fees, and a 2-week free trial with no credit card up front.
Your score is one survey away.
