Airbnb's business allows people to rent out their homes and spare bedrooms to travelers around the world. Chesky says the company has had some notable successes lately — during the 2014 World Cup in Brazil, for instance. Chesky claimed that 20 percent of visitors to Brazil for the tournament stayed in an Airbnb, more than 120,000 people.

Airbnb also just launched in Cuba in April with a thousand listings, a number that has since doubled. Of course, Cuba was a destination off limits to American tourists just six months ago, so it's a small market for Airbnb, but it goes to show that Airbnb is (quite literally) almost everywhere.
Where else is Chesky eyeing?
"Antarctica. The North Pole, we're working on. And we'll kind of move off of Earth from there," he joked.
