How do you decide if another person would be a good co-founder?
mixmax: I talked to an old guy that ran a large trucking company some years back, and based on his own experience he gave me the following advice: Never start a business with people that have the same qualifications and interests as yourself. He had once started an unsuccessful trucking company with three other trucking people. The result was that they had amazing trucks that were always in perfect shape, but sales, marketing, finance, and all sorts of other things didn't get done. And they failed. His current company was started with an accountant. So try to find a partner that finds the stuff you're uninterested in interesting.That said, finding a co-founder is hard - you don't know whether it'll work out before you'e tried it. So the best advice is probably to test each other out, maybe by doing a small project first, and seeing how it goes. Additionally you should have a written agrement on what happens if it doesn't work out.And most important of all: Don't take it personally.
