Remember that most startups don't have a "single founder" and the founder who becomes the "face" of the startup if it goes big is not necessary the only contributor to the success.

Older partners may have less time to dedicate to the startup, or have other reasons to hold back.

It may also indicate that a percentage of startup success is attributable to networking effects, which mostly grow with age.

I think the biggest thing to start a successful business is to not start a startup.
