PositiveReutersElon Musk can be a vulnerable person. That’s one of the surprising insights from a new book about the founding of PayPal ... It’s a dramatic business story about the payments company’s rise. But it’s also a human tale about Musk, Peter Thiel, and Max Levchin ... Soni captures the heady days of the dot-com bubble in 1999 ... The Founders also gives due recognition to Levchin, who is often overshadowed by his more controversial colleagues ... The author had impressive access to the key players, including Musk, Thiel and Levchin, along with those who were closest to them in those early years. It would’ve been enlightening to hear more from them about how they applied their PayPal experiences. Still, the book is rich enough that readers can infer the lessons the founders learned in a more innocent time.
