The idea for Uber came about after Camp and Kalanick spent a pricey $800 hiring a private driver on New Year’s Eve, and Camp needed help finding a taxi on a snowy night in Paris. Camp, Oscar Salazar and Conrad Whelan built the prototype for Uber’s mobile app, with Kalanick as the chief advisor to the company. Ryan Graves became the first Uber employee in February 2010 and was named CEO in May 2010. In December 2010, Kalanick succeeded Graves as CEO, and Graves became the chief operating officer. Uber’s current CEO is Dara Khosrowshahi, who replaced co-founder Travis Kalanick of Uber in August 2017.
In August 2016, DiDi acquired Uber’s business operations in China, and in exchange, Uber obtained an 18% equity stake in DiDi. DiDi also pledged to invest $1 billion in Uber as part of the agreement. Later that year, Uber purchased Ottomotto, a startup specializing in developing autonomous trucks. The acquisition was valued at $625 million, and the founder of Ottomotto, Anthony Levandowski, was previously accused of stealing trade secrets from his former employer, Waymo, to establish the company.
