Travis Kalanick, the pugnacious co-founder of Uber, has severed his last ties with the ride-services company, resigning from the board and selling all his shares as he turns his focus to a new venture creating "ghost kitchens" for food delivery services.
Kalanick, who helped found Uber in 2009 and once exerted nearly complete control, stepped down as chief executive in June 2017 under pressure from investors after a string of setbacks.
He will depart Uber's board of directors by the end of the year, the company said on Tuesday.
