I checked with him and he's fine, but I think probably also in shock. In case it helps, I haven't seen any signs of blame; everyone knows we could easily have done it ourselves. The general feeling seems to be that it motivated us to do something that we wanted to do in the first place, but thought we couldn't.
Yea, it's a shitty position to be in but it could happen to any of us. Hope he won't be too hard on himself. With that being said, we were one of the originally rejected and then accepted startups. I guess that means we're part of the advisory track. I just hope that YC can still dedicate the originally-intended resources to the advisory group.
