Ten years ago, the idea of getting into a stranger's car, or walking into a stranger's home, would have seemed bizarre and dangerous, but today it's as common as ordering a book online. Uber and Airbnb are household names: redefining neighbourhoods, challenging the way governments regulate business and changing the way we travel.

In the spirit of iconic Silicon Valley renegades like Steve Jobs and Bill Gates, a new generation of entrepreneurs is sparking yet another cultural upheaval through technology. They are among the Upstarts, idiosyncratic founders with limitless drive and an abundance of self-confidence. Young, hungry and brilliant, they are rewriting the traditional rules of business, changing our day-to-day lives and often sidestepping serious ethical and legal obstacles in the process.

The Upstarts is the definitive account of a dawning age of tenacity, creativity, conflict and wealth. In Brad Stone's highly anticipated and riveting account of the most radical companies of the new Silicon Valley, we find out how it all started, and how the world is wildly different than it was ten years ago.
