After spending months going deep on startup postmortems, I noticed the same 3 patterns showing up again and again across 127 failed companies.
Not the ones people usually cite. The real patterns:
1. Premature scaling killed more startups than competition did
51 of 127 companies I studied had this as a primary failure factor. They scaled marketing, headcount, or infrastructure before confirming unit economics actually worked. By the time it was obvious something was wrong, the runway was gone.
Quibi had 12 million downloads. They still burned through $1.75B and shut down in 6 months.
2. Founder-market fit > product-market fit
The product was fine. The market existed. But the founder didn't have the domain expertise, network, or distribution edge to win in THAT specific market.
Color.com raised $41M in 2011 for photo sharing. Same week Instagram launched. They had the money. Instagram had the founder who understood mobile social natively.
3. Most startups don't die from one big mistake
They die from 3-4 small, compounding mistakes happening simultaneously — while the team still thinks each one is fixable. By the time they realize the compound effect, it's too late.
I built a structured database of all 127: failure type, funding raised, years active, and the extracted lesson from each.

What patterns have you seen in companies you've watched fail? Curious if this matches what others have noticed.
