Airbnb puts the “unique” into travel by connecting private owners renting out a room, apartment, castle, or villa to travelers staying a night, a week, or a month. This community marketplace of accommodations spans 34,000 cities and 190 countries. More than 17 million guests have over 800,000 listings to choose from. People can book accommodations or monetize extra space through the web or their mobile phone. THE CHALLENGE Trust is foundational to the sharing economy. There is no place for anonymity in a community based on trust. That’s why Airbnb is dedicated to providing their users with the best decision-making tools possible.
