A lot of people regard being 14 years old as a valid excuse for not starting your own company. Not Ben Casnocha, though.

I think Ben started his first company with 12, at least that's what I got from the Amazon page of his book.

Edit: From his personal webpage: http://bigben.blogs.com/website/personal.html

"Not counting gumball or pen businesses, I started my first company when I was 12, and my first "real" company (Comcate) at age 14, an e-government software company which serves cities and counties throughout America."
