Book excerpt: When Peter Thiel and Max Levchin launched an online payment website in 1999, they hoped their service could improve the lives of millions around the globe. But when their start-up, PayPal, survived the dot.com crash only to find itself besieged by unimaginable challenges, that dream threatened to become a nightmare. PayPal's history as told by former insider Eric Jackson is an engrossing study of human struggle and perseverance against overwhelming odds. The entrepreneurs that Thiel and Levchin recruited to overhaul world currency markets first had to face some of the greatest trials ever thrown at a Silicon Valley company before they could make internet history. Revised and updated, this narrative is an adventure in capitalism. Reveals how PayPal went from bleeding $10 million per month to becoming a financial powerhouse. Sheds light on eBay's current woes, and PayPal's pending showdown with Google. -- Publisher.
