What makes you think you NEED to stay in control and "provide vision"? I started alone and within a month realized that I was going crazy. Then I teamed up with my long-time dev. partner and he not only provided some initial funding, but introduced us to a few very interesting people, then we got a 3rd guy who's like Linux God, who I keep learning new things from every day, now we're about to add a kick-ass marketing muscle - the dude keeps impressing us with his ideas and suggestions.
Right now, at this moment, if I pretend I am dead for a day, I still know the gears will keep rolling and the engine will keep accelerating. This is an enormously helpful feeling: stop being greedy and give your company a chance to survive.
That's my 2c.
