Tesla has added Airbnb co-founder, designer and billionaire Joe Gebbia as an independent member to its board of directors according to a regulatory filing out Wednesday. Gebbia left his operating role at Airbnb in July this year but remains a board member there and chairs the Airbnb.org nonprofit, which helps people displaced during times of crisis to find at least temporary housing. Gebbia’s addition to the Tesla board follows the departure of Oracle CTO and chair Larry Ellison.
