In 1999, at the age of 24, Tony Hsieh (pronounced Shay) sold LinkExchange, the company he co-founded, to Microsoft for $265 million. He then joined Zappos.com as an advisor and investor, and eventually became CEO, where he helped Zappos.com grow from almost no sales to over $1 billion in gross merchandise sales annually, while simultaneously making Fortune magazine's annual "Best Companies to Work For" list. In November 2009, Zappos.com was acquired by Amazon.com in a deal valued at $1.2 billion on the day of closing.

Tony's first book, "Delivering Happiness", was published on June 7, 2010, and outlines his path from starting a worm farm to life at Zappos.com. Tony shows how a very different kind of corporate culture is a powerful model for achieving success and happiness. "Delivering Happiness," debuted at #1 on the New York Times Bestseller list and remained on the list for 27 consecutive weeks.
