Why we picked it CB Insights read hundreds of real startup postmortems and found that poor product-market fit (around 43 percent) is the single biggest root cause of failure, ahead of running out of money. If you want to spot the warning signs early, start with the patterns of founders who already hit them: a market too small, a problem not painful enough, a product nobody urgently wanted. Treat it as a checklist of ways an idea can quietly go nowhere for a year.
The Top 12 Reasons Startups Fail
From CB Insights by CB Insights ~15 min read
- The top root cause of failure is building something with no real market need, not running out of cash (cash is usually where the story ends, not why).
- Weak demand often hides behind early traction, so polite interest and a few friendly users can mask an idea that never widens into a market.
- The list doubles as an early-warning checklist: if your idea already leans on bad timing, thin unit economics, or a problem people can live with, take that seriously now.
