For YC founders, by YC founders

The YC community is home. We invest exclusively in YC founders, because it's the most valuable startup ecosystem in the world — and there's nowhere we'd rather spend our time.

Built for the long run

Demo day is just the beginning. We try to be the kind of investors we wanted ourselves — celebrating the wins, showing up during the hard parts, and staying close through the long middle.
