The last truly in-person YC batch, W20, ended abruptly in March 2020. Everyone was told to go home, and we all left thinking we'd do a belated demo day party sometime in the summer. Of course, it never happened and a lot of us never even returned to the city. Three years later, YC is somewhat IRL again, but there's still no official alumni demo day. I figured I'd at least host something small and Brex graciously offered to sponsor. We were able to gather forty folks across thirteen years of YC, from batches S10 all the way to W23. It's clear that everyone missed the in person stuff, and below are some small moments from the afternoon. I'm optimistic that we'll be seeing more of these gatherings soon :)
