6. Steve Wozniak

Vision: Advent of Personal computing

Achievement: Macintosh

Teamed up with Steve Jobs, Wozniak compromised many things in his life to build the first personal computer. To raise the first funds for designing the prototypes of the Mac, Wozniak had to sacrifice his HP scientific calculator. Though, Steve Jobs would forever remain the face of Apple Inc, Wozniaks contribution to build the Apple empire cannot be forgotten.

7. Mark Zuckerberg

Vision: Know what your friends are up to.

Achievement: Facebook

The Harvard drop out had barely any experience in business and hardly any money to start his entrepreneurial venture. In those times he relied completely on his gut and believed in the people around him. Now with a multi billion tech IPO, Zuckerberg stands to be one of the youngest successful entrepreneurs ever. Shot with many controversies all the time the leader of Facebook never gives up on the fighting spirit and keeps going forward.
