culture as strategy / *Delivering Happiness*

Tony Hsieh served as CEO of Zappos for over two decades, growing it from a small online shoe retailer into a billion-dollar business acquired by Amazon in 2009. He staked Zappos's success on radical customer service and a codified set of core values, arguing that culture is a company's ultimate competitive moat. His memoir *Delivering Happiness* (2010) became a New York Times bestseller and a touchstone text for purpose-driven business.
