Bill Ackman is the founder and CEO of Pershing Square Capital Management, one of the most closely watched investment firms in the world. In this conversation, he breaks down how he tells the difference between real innovation from hype, what he looks for before making a billion-dollar investment, and why he sold Netflix—and later bought it back. He also shares the mistakes that reshaped his investment process and his plan to build a modern-day Berkshire Hathaway. Bill also opens up about something far more personal: his daughter Lucy’s sudden brain hemorrhage, the hours before surgery, and her ongoing recovery. He describes running his business from a hospital room and the institute he and his wife are building to help other families facing similar challenges.
