Earlier quoted context omitted.
Sure, but this doesn't explain why most people working in startups are in their twenties.
Is that true? Or is that just what people want to see? Avg age at my company (Series A funded, 50-ish people) is >30. Founders started at 35 & 36. Now they’re not-quite-40 and 40. Your sample size may vary.
At my startup, in my late 20s, I'm one of the older employees, excluding founders & management.
