Elon Musk, 2007

Inc. Magazine named Elon Musk Entrepreneur of the Year way back in 2007 when he was best known as the co-founder of PayPal--but it is clear the South-African entrepreneur has moved on to bigger things since. Today, the CEO of SpaceX and Tesla Motors is one of the most talked about names in the start-up world from his work with NASA to his latest big idea he unveiled this August, the "hyperloop"--a high speed train that would take passengers from San Francisco to Los Angeles in 35 minutes.
