Elon Musk has had his hands in several different companies over the years. Originally enrolled at Stanford University, Musk deferred his attendance to launch Zip2, one of the earliest online navigation services. A portion of the proceeds from this endeavor was then reinvested to create X.com, an online payment system that later became PayPal.
