I applied to the GSB deferred program the spring of my Senior year at Brown and didn't even get an interview :,(
Around the same time I got rejected from GSB, I also interviewed at Y Combinator for the S20 batch with Artistprof. We were told that this was a "new grad" idea.
With an awesome team, I tried to build a personal relationship manager, Anchor. Monetization in the PRM space proved too difficult.
