Travis Kalanick has resigned as CEO of Uber after shareholders of the ride-hailing service demanded his ouster, The New York Times reports. Investors reportedly delivered a letter to Kalanick on Tuesday titled “Moving Uber Forward” in which they demanded an immediate change in leadership. Kalanick, who helped found the company in 2009, will remain on the board of directors but has agreed to resign as CEO. “I love Uber more than anything in the world and at this difficult moment in my personal life I have accepted the investors’ request to step aside so that Uber can go back to building rather than be distracted with another fight,” he said in a statement. The shakeup comes after a turbulent year for Uber, with the company hit by sexual-harassment allegations and a federal inquiry into its use of software to allegedly sidestep law enforcement.
