Tony Hsieh
Tony Hsieh calls happiness a business model -- and not just because his book, Delivering Happiness, is a best seller. "There's power that comes from matching corporate values with personal values," says the Zappos CEO, whose fun, fresh employee culture helped turn the shoe commerce site into a billion-dollar brand. At the 12-year-old company's new Las Vegas HQ, for example, Hsieh plans to host indie concerts and build small crash pads -- replete with a bed and closet -- that can be rented for $100 a month. To help other firms follow suit, Hsieh in March launched a motivational consultancy, also called Delivering Happiness, that will advise on company culture (one tip: source your mission statement from a scrapbook of employee testimonials), as well as offer packaged experiences, such as pottery classes and helicopter lessons.
