Interesting idea and I hope it works out.

The problem I see is that you can't exactly apply the online dating model to finding a co-founder. With online dating, you presumably date a number of people before finding someone acceptable/awesome. Sometimes it takes multiple dates to figure things out for sure.

But for a start-up founder, you can't go start multiple companies just to be sure they are the one. You need a level of trust and an ability to work together that you just can't get from a couple of lunch meetings.

I do hope they can prove me wrong though, because that would be awesome.
