According to statistics I recently heard, you'd be twice as likely to have a successful exit if you were 50 than 30 when founding, but you'd also find getting investment more difficult because investors prefer younger founders. (I guess that means investors must not be particularly data-driven.) Those stats might reflect that 50 year old founders might not be on their first attempt, so perhaps it doesn't apply to you as a first time founder. But still, 30 does not sound too old. All those people around you on their 2nd/4th company: They indicate a culture, but it doesn't mean their current companies are going to be particularly successful if that's measured by a large exit. Perhaps they will get that by their 6th company which they start at age 40, if they aren't burned out by then.
