>I'm not really sure how you solve this problem, or if sites like CoFoundersLab can solve the problem.
I think it might have to do with the approach that they're using. When someone comes here and posts an Ask HN about how to find a cofounder, people frequently mention how it's important to actually have a working relationship with the person you're starting a company with. A common piece of advice is to just start working on a side project with someone and see where it goes. CoFoundersLab profiles (and to a certain extent my interactions with people on the site) seems to focus on "here's what my background is, here's what I'm willing to invest, this is the industry I want to go in". It's less about "I have this idea, if anyone with background X thinks this is cool and wants to help me out, feel free to get in touch". Its a subtle difference, but I think it makes a big difference to not trying to 'force it'
