Why Study Startup Failures?

93%

of startups eventually fail. Understanding patterns gives you an unfair advantage over founders who only study success stories.

42%

fail because they build something nobody wants. The most expensive mistake is not running out of money — it is building the wrong product.

29%

run out of cash before reaching profitability. Every case study in this database shows exactly where the money went and why it was not enough.

23%

fail due to wrong team dynamics. Co-founder conflict, missing expertise, and governance failures destroy more startups than bad markets.

Sources include SEC filings, TechCrunch, Bloomberg, The Information, and founder interviews. Funding data reflects publicly reported figures. Estimated values are marked accordingly.
