Startup Idea : Group dating in Paris

When I had this idea, I was thinking that people would definitely love something like grouper in Paris (France) area. I tried to join grouper with some of my friends but I couldn't. Grouper is not available on Paris yet.I was very enthusiastic about the concept and everything, but I noticed that all their matching work was done manually. I started thinking wtf?, is this the only way to do this ? And then I saw many other things that made me think that a way better product could be done. If this appeals you and that you are a dev or a graphist, please join !
