I believe that doing /something/ with someone over and over again is the best way to meet a cofounder. When I get enough people (6-20) in a given city, I will organize an event along the lines of playing board games, going to a driving range, or volunteering in some way. The main point is that it's not just people drinking or standing around, they have to be active participants in the activity.
The goal is for you to go to a number of these events, see how others behave and start to build relationships with them. Then you go off and build something with them.
Would love to hear your feedback.
