The startup myth says founders are in their twenties. The data says otherwise. If you're starting at 40+, with a family, a mortgage and a new field to learn, here is what the evidence actually shows.
The average age is 45#
- A study by Azoulay, Jones, Kim and Miranda using US Census data (NBER) found that "the mean founder age for the 1 in 1,000 fastest growing new ventures is 45.0."
- The same study found that "prior experience in the specific industry predicts much greater rates of entrepreneurial success."
- Media lists suggest otherwise: TechCrunch award winners had an average founding age of 31 (HBR).
What gets in the way#
- The OECD lists barriers for older entrepreneurs: skills gaps (including digital), outdated networks, finance, health, care responsibilities and age discrimination.
- The GEM 2025/2026 report finds fear of failure deters 2 in 5 adults, and warns of an "AI Readiness Gap".
How 40+ founders win#
- Build in the industry you know.
- Test small before you jump (see our 90-day checklist).
- Close the AI gap on purpose (see our AI tools guide).
- Rebuild your network with peers: join an Atlas Circle.
You're not late. You're equipped.
