What's the Latest Development?

When Michael Simmons made $40,000 his senior year of high school working 10 hours per week, it completely changed his paradigm of what was possible as a young person, he says. Just a few years later, he and his girlfriend, Sheena Lindahl, launched their company. "The couple began speaking about entrepreneurship—at college campuses, high school groups, and other organizations, and they built a website to promote themselves. In 2006, their start-up became Extreme Entrepreneurship Tour."

What's the Big Idea?

Selling the idea of entrepreneurship has become a lucrative market in its own right: "Extreme Entrepreneurship Tour now organizes 100 entrepreneur events, conferences, and panels a year. Speakers include Ryan Allis, 27, who leads iContact, a $50 million e-mail marketing company, and Scott Becker, who sold his InviteMedia ad firm to Google for an estimated $80 million last year, when he was just 23. Lindahl, who handles operations, is president, and Simmons, the big-idea person, is chief executive at Extreme Entrepreneurship Tour."
