find a cofounder! yc generally funds teams and isn't in the business of matchmaking.

("find a cofounder" is what pg will probably tell you; it's what he told me repeatedly before my interview. it was a big time investment to find the right one, but completely worthwhile. couldn't imagine going through this alone, and it only gets harder to get a cofounder the longer you put it off -- it no longer feels like 'their' idea.)
