The long term answer is to build a hacker network. That's going to be hard.

There is no good short-term answer but here's the only way: asking in the right places (like here) and getting very lucky. Being specific will help:

Do you have actual ideas? Do you bring domain knowledge to the table? Are your ideas niche to that domain? Do you know what type of business you'd want to run (bootstrapped/VC)? How are you going to get funding?

As a programmer, I know several hackers who are looking to start a business in the next year or so. If you had good answers to the above questions, I'd consider putting you in touch with them. Regardless, though, you are going to want to be specific as possible when asking. It's the only way of even having a chance.

Bonus tip: Put your email address in your profile before asking questions like this. You never know who might email you out of the blue.
