1. Apple: Steve Jobs & Steve Wozniak
Steve Jobs, a dropout of Reed College in Portland, Ore., and Steve Wozniak, a dropout of the University of California, Berkeley, joined forces and founded Apple Computer in 1976. The two became friends when Jobs worked for a summer at HP, where Wozniak was working on a mainframe computer.
Thirty-seven years later, the company they built is valued at a whopping $600 billion.
