A good way to increase your chances of finding one is to do a lot of small projects with different people who complement your skills. You have to work with someone first to know if you are a good fit for something bigger (think of it as dating before marriage).

We created http://www.doerhub.com as a free tool to fix that. People from different disciplines (from surgery, to hacking, AI, business, law, 3d printing and human rights ) post what they are working on/passionate about and anyone who likes their project can contribute by joining, advising, becoming a beta user, doing a task etc. They collaborate right on the site or outside of it. You can share areas you are advanced in and learning in so you can discover complementary people easily http://peoplesearch-doerhub.herokuapp.com/viz/ and do private or public projects.
Other than individual SV doers, UChicago was first full organization in our beta http://www.doerhub.com/at/uchicago (1/3rd of the finalists and both winners of their New Venture Challenge and Social New Venture Challenge were using the site). And now we are opening it for free to other universities, hackathons, hack clubs and organizations who want people to get stuff done with others, instead of just talking about it.
