My personal opinion is that by the time you have a business you want to build, you should already be close to several people who you'd like to work with. The feeling should be mutual. That means building a relationship -- trust, rapport, history, etc. -- before there is any extrinsically motivated need to find and know someone, whether they are technical or otherwise. I'm sure some people can make things work with a team that is in essence a group of mutually hired guns [1]. I don't think I can succeed in that kind of relationship, and so I actively shun it. [1] admittedly, I can see how such an arrangement can at times be valuable.
