Actually, I just looked at the "famous alumni" lists on Wikipedia and filtered for a.) companies that we've heard of where b.) the founder's MIT degree was somewhat relevant to the company. There was some fascinating...TIL that Campbell Soup took off through the skills of an MIT-trained chemist who invented condensed soup, and that the National Enquirer was turned into a tabloid by an MIT-trained engineer who had worked for the CIA's psychological warfare unit. I can just see the conspiracy theories fly on that one.
