The Sean Ellis Product-Market Fit Survey (40% Test)
From Startup Marketing / GrowthHackers by Sean Ellis ~10 min read
Why we picked it
The original, still-used test for whether you have product-market fit, from the person who coined 'growth hacking' and grew Dropbox and others.
- Ask users how they'd feel if they could no longer use your product.
- If 40%+ say 'very disappointed', you likely have fit worth scaling.
- Below 40%, growth spend accelerates churn instead of revenue.
