2013: garry tan builds bookface, a literal book of faces for YC founders
2026: 4m lines running applications, interviews, startup school, cofounder matching, work at a startup, launch yc, and 350+ internal AI tools on one postgres
over 2m of those lines showed up since march.
they also got the whole thing onto the latest rails and react, first time since 2013.
YC still isn't a software company.
it just happens to run on 4m lines of its own, and that's the direction every company is walking in, whether or not they sell any.
