Drummond's departure ends a three-year stint with the company that began in 2013, when Google invested 360 million in Uber. Both companies released statements attesting to their continued collaborative spirit. "I wish David and Alphabet the best, and look forward to continued cooperation and partnership," Uber CEO Travis Kalanick said. Drummond said that Google Ventures "remains an enthusiastic investor and Google will continue to partner with Uber."
