>and who's a former co-founder of a co. with a billion-dollar exit

I know your point wasn't entirely literal but it made me curious as to how many YC founders are in this position...Kyle with Twitch and then Cruise is the only one that comes to mind.

Suhail from Mixpanel (S19) and Laks from Zenefits (W19, my batch) were both in recent batches! So they definitely exist. Much more common is the non-huge-exit but still successful second-time founders

Mixpanel got acquired? I don't think Suhail had an exit (yet).
