Uber will invest $400 million into Aurora, and Uber's CEO Dara Khosrowshahi will join Aurora's board of directors, the companies said. After the transaction, Aurora will be worth $10 billion and Uber will hold a 26% stake in the company, Chris Urmson, CEO of Aurora, said in an interview. "Our first product will be in trucking and freight, but we look forward to taking this great team that we have and accelerating that while continuing working on light vehicles and ride-haling, and we'll ultimately see our vehicles deploying on the Uber network," Urmson said. Aurora, based in Mountain View, Calif., is led by former Google, Tesla and Uber executives. Aurora also has partnerships with delivery giant Amazon and auto companies Hyundai and Kia, among others, but its partnership with Uber is its first official relationship with a ride-hailing company.
