Interesting that you would call it the most successful, given that the general consensus on tech blogs (whatever that's worth) is that it was a talent acquisition/distress sale. I think the founder's statement came across as an unhappy ending (not what he envisioned, but that could have just been the way I read into it). It was a pretty cool interface for a photo site but unfortunately the most memorable thing I knew about the company was the drama with that teen from techcrunch trying to have the Divvyshot founder buy him a Mac to get favorable coverage on Techcrunch.com

I'm about to start work as a new employee at a YC alumni, hopefully we'll do better!
