Jason Fried, 32

37signals builds aggressively simple Web-based collaboration tools that help people manage everything from family to-do lists to big corporate projects. Hundreds of companies are using Ruby on Rails, the open-source software toolkit that the firm created, to quickly
develop their own online applications. Jason Fried, the founder and president of the seven-person firm, is fond of saying, "It's better to tell a short story well than a long one poorly." In that spirit:

“Jason is immune to dogma and has much to teach. In 37signals, he has built an elegant company with elegant products based on the idea that less is more.” --Jeff Bezos, CEO, Amazon.com, and the first outside investor in 37signals
