Founder Dating claims to do that to an extent, but you have to apply and be accepted to one of their events.

As a non-tech looking for a technical co-founder, I got fed up with this search and decided I'd be better off just learning to build and code my idea(s) myself. It was actually the questions on the Y combinator app that made me realize that once you push out past the second or third degree of separation in your social network ("oh yeah the friend of my friend of a guy I used to work with can code") you're too far removed from this person, and a co-founder you don't know or can't trust seems like far greater a risk than investing the time to learn to do it yourself. Plus once you build your first project, I suspect it gets exponentially easier to make the next and the next thereafter!
