Designer, entrepreneur, and Airbnb co-founder, Joe Gebbia, was known as the “art guy” in grade school when he started his first business selling illustrations of Ninja Turtles. Then, while pursuing dual design degrees, he founded his first legit startup with RISD’s basketball team, The Balls. Now as the leader of innovation and ideation at Airbnb he’s focused on exploring new attitudes of sharing and trust. Oh, and don’t tell him he can’t do something. He will go to extremes to prove you wrong. Isn’t that so, Professor Jones?
