Airbnb's genius was moving into cities and recognizing that millennials would want to go and maybe spend a vacation or visit some friends in an urban center.
Airbnb is a company with values around hospitality.
I'm not saying the whole world will work this way, but with Airbnb, people are sleeping in other people's homes and other people's beds. So there's a level of trust necessary to participate that's different from an eBay or Facebook.
People don't use Airbnb overtly to trust people more. They use it because they want to get a better sense of the culture and to save money. A by-product was that they live in someone else's shoes.
I think the key that makes Airbnb is the fact that we're a community, not just a series of commodities.
Airbnb is different from most brands. We're a community of individuals, and yet there's a consistency holding us together through the values we share. We have a common belief in belonging, but everyone's expression of it will naturally always be a little different.
In June 2010, I moved out of my apartment and I have been mostly homeless ever since, off and on. I just live in Airbnb apartments and I check in every week in different homes in San Francisco.
What I've been surprised by is not how different people are, but how similar they are. There are certain types of Airbnb people, and they are in every city in the world - it's just that in some cultures, there is more of a generational divide.
