The book is about “a massive failure in Silicon Valley,” that had “all the best investors” and “all the best executives,” Gurley said.

“And it’s just spectacular, because on the way home from work every day he had a tape recorder and he left himself notes, so it’s remarkably detailed,” Gurley said. “We spend so much time analyzing success, and sometimes it’s just good to read how hard it can be. And why it can be so hard. So that one’s a real world account that I love.”
