This sounds like a company that would have benefited from a program like YC. It would have given them a peer group of entrepreneurs that would have pressured them to keep shipping product, filled in some of the totally understandable gaps in their knowledge (for example around engineering management and best way to time their Series A), and kept their success in context (just about everyone feels like a little fish next to Dropbox and Airbnb, and little fish swim harder.) If they'd had these things two years ago they might be in a very different position today.
