It goes without saying that if you've ever met these two, you know they're in a league of their own. They have the same kind of unstoppable, world-be-damned nature that I've seen in the Justin.tv and Airbnb teams, which is inspiring and humbling at the same time. And as Prayag mentioned, they've both extremely nice and down to earth.
They deserve nothing but success - best of luck to both of them.
