Delivering Happiness was co-founded by Tony Hsieh (CEO of Zappos.com) and Jenn Lim (CEO of Delivering Happiness). In 2010, the book Delivering Happiness: A Path to Passion, Profits, and Purpose became a top bestseller, sharing the belief that happiness can be used as a model both in business and in life. After the book launch, there was a bus tour that solidified people were making happiness a priority in their own lives. Now, Delivering Happiness is a company and a movement. Backed by studies within the science of happiness and positive psychology, as well as best practices from Zappos and other successful companies, Delivering Happiness has developed frameworks that universally apply to businesses that create sustainable culture change.
