#1 Mark Bao, 19

Mark Bao had his first encounter with entrepreneurship in the fifth grade. He used Visual Basic 6.0 to write a simple computer application that managed his homework assignments and helped him write school papers. Then he copied the program onto floppy discs and sold them to his friends.

His first start-up came in his first year of high school. Debateware.com was an event management system for debate organizations. Eventually, Mark and his business partner sold it to the largest debate organization in the United States.

Mark at the age of 17, a high school senior, launched 11 web-based companies (and sold three of them) along with three non-profit foundations.
