Jobs had to persuade him to leave HP, and do all the selling and marketing, those are also important parts of building a business. In my view it was a partnership and you're ignoring a huge part of what made Apple Apple. That leaves you with Google, which also had two very early significant players.

I'm not arguing against single founders, it's perfectly possible, but most companies are not started by a single founder, they are collaborations and are all the better for it.
