pg says in the application page: "The ideal company would have two or three founders. We'll consider those with four or five. We're reluctant to accept one-person companies, though we have funded a couple." so I hope that wasn't the reason why we got discarded. But if it really is a hard rule it'd be a strange rule, any 4 person team would pretend to be a 3 person team and include the "extra person" immediately after getting in...
