But he said he was optimistic about the future, especially given the decade he had spent at Zappos in different roles. “The culture is not just one person or two people,” he said. ... Zappos, which derives its name from “zapatos,” the Spanish word for shoes, was an early e-commerce success story under Mr. Hsieh, who wrote a best-selling book in 2010, “Delivering Happiness: A Path to Profits, Passion, and Purpose.” It argued that a company’s top priority should be its culture and that keeping employees happy translated into success with customers.
