Bloomberg's Brad Stone on the Rise and Impact of Uber and Airbnb

Few companies have altered city life as deeply and swiftly as Airbnb and Uber, writes Bloomberg technology editor Brad Stone. The two companies, which together are now worth $99 billion, have generated controversy in every urban center they’ve entered, outpacing regulation and agitating entire industries. We speak with Stone about the people behind the rise of Airbnb and Uber, and about the “nonstarters” — those who had similar ideas but whose businesses failed. Stone’s new book is “The Upstarts: How Uber, Airbnb and the Killer Companies of the New Silicon Valley Are Changing the World.”
