The programmers I know are pretty good but they also have PHB (pointy haired bosses) and also hate some things of working in a big corporate.
Learn to develop one. It doesn't need to be as good as Steve Job's, but being able to persuade people that you're onto something is a pretty essential skill as a start-up founder. In fact, I wouldn't start up unless you are able to convince a few people that your proposed business is really good and worth backing. Consider it a first hurdle.
If you can't convince people to join up with you, either your pitching skills are not good enough (so improve them) or your idea sucks (so iterate through that).
And, as others have said, if that person is not really interested in the start-up life, don't push them... find someone else (unless that person is a genius).
