I believe it depends on the personality of the entrepreneur. For some, working together with others is much more likely to produce success. Richard Branson seems to be in this category, and it sounds like you are too. At the other extreme, some founders' personalities are such that they almost have no choice but to build it completely on their own - a "lone ranger", as a investor I once knew put it. My favorite example of this is Felix Dennis, founder of Dennis Publishing (which publishes Maxim, and many other magazines). (That's not to say lone rangers build their company alone; if that's ever been done, I don't know about it! But the additional key people are employees, not founders, and may not even get equity.)
