A quick, periodic reminder of what we do @ridgevc: Invest $2-7M in $3-12M rounds (large Seed or early Series A) backing enterprise founders with deep domain expertise. Think @LoopReturns, @outlierai, or @Braze. We can lead or follow, flex on ownership, and bring F500 customers.

In the context of the national discourse, Stanford unequivocally condemns calls for the genocide of Jews or any peoples. That statement would clearly violate Stanford’s Fundamental Standard, the code of conduct for all students at the university.
