Well it seems you have an unfair advantage here :). You have been watching him go through it and taking notes. He is also going to advise you on product, growth, etc. I hope you win this bet, however you must win it by at least 3 folds (maybe 3 times the number of users, or 3 times the revenue) to be able to call it a clean win. Good luck and congrats to you guys (it wasn't just him, obviously. I am sure your support tremendously helped).
