I really like this concept OP. I think your biggest non-technical hurdle is going to be dealing with the classic issue of there simply being significantly less women than men. I'm curious to know how you plan to approach that after you introduce a proper business model.

Former speed dating entrepreneur here. In person, at least, women are much more open to the idea of speed dating than men. Much of our marketing revolved around how to appeal to and attract men to our events.

Interesting, I'm curious to know what kind of speeddating events/services/apps are out there. I've never used any.

I'd focus heavily on hotdog detection, lewd language detection, and other ways of terminating calls (and banning users) that break a code of conduct in the calls.
