This is the inside, behind-the-scenes story of Airbnb - the company reshaping how we travel. Two broke art school graduates set up a platform that - in six short years - became the largest provider of accommodation in the world. Now valued at $25.5 billion, it is in the very top tier of Silicon Valley 'unicorn' startups. Yet Airbnb has been controversial. This is the first, definitive book to tell the remarkable story behind Airbnb in all its forms - cultural zeitgeist, hotel disruptor, enemy to regulators - and the first in-depth character study of its leader Brian Chesky, the thoughtful, curious 34-year old founder and CEO, by the journalist who knows him best.
