Is anyone aware of a similar thing for the US? I've been using Kiva for years with monthly injections of more money and "reinvesting" everything I get paid back. It's a little different as I'm not exactly looking for profits. I don't think you really get more/interest back on Kiva but I could be wrong since I've had a few loans default so that might have just wiped any meager gains.
