The famous account of Airbnb’s origins—how Chesky and Gebbia stumbled upon the idea to rent out space in their apartment when a design conference came to town and maxed out San Francisco’s hotel supply—has been told thousands of times. But the real story is more complicated. The founders didn’t think AirBed & Breakfast was going to be anything at all; they thought it was a creative way to pay the bills while they thought of their really big idea. Once they decided to make a go of it, they were confronted with rejection and failure over and over again. But through hustle, tenaciousness and creativity--plus a few key assists--they got it off the ground, and then saw their company soar to a size and significance they never imagined. That to me is the most captivating part of the story: How these three guys with unconventional backgrounds and an unorthodox idea proved so many people so wrong.
