Hey, I started Tennis Buddy, thought I'd chip in what we had in mind. Everything we built upon is what what Matt Cohler said last year at TC disrupt to the question that the next big thing in mobile is gonna be that you just "push a button and something amazing happens in the user’s world.". http://techcrunch.com/2012/09/21/great-mobile-apps-are-remot...

That's what the Uber for X is, it doesn't matter if it is cars, services or in our case - people. If you need something, just let everyone know in your area by simply pressing one button and they'll come to you.

So for now, you can find someone nearby to play tennis with you, whenever, wherever you want to :)
