Entrepreneur and startup advisor Sean Ellis discovered a leading indicator of product/market fit: Just ask users “how would you feel if you could no longer use the product?” and measure the percent who answer “very disappointed.”

After benchmarking nearly a hundred startups, Sean Ellis found that the magic number for product/market fit was 40%. Companies that struggled to find growth almost always had less than 40% of users respond “very disappointed” in the survey, whereas companies with strong traction almost always exceeded that threshold.
