viz. Bill Gates, who is changing the world and doing good in more tangible ways than almost any startup, despite having built up Microsoft with the clear focus of make money and dominate the market first, change the world later.
Let's be fair to Microsoft--their mission statement was "a computer on every desk and in every home, all running Microsoft software". By the time Gates stepped down as CEO, they achieved that. For all its flaws and the sorry state it finds itself in today, Microsoft was more worldchanging than most startups.
