In 2009, Garrett Camp, a co-founder of StumbleUpon, came up with the idea to create Uber to make it easier and cheaper to procure direct transportation. Camp and Travis Kalanick had spent $800 hiring a private driver on New Year's Eve, which they deemed excessive, and Camp was also inspired by his difficulty in finding a taxi on a snowy night in Paris.[6][7] The prototype of the mobile app was built by Camp and his friends, Oscar Salazar and Conrad Whelan, with Kalanick as the "mega advisor" to the company.[7]

In February 2010, Ryan Graves became the first Uber employee; he was named chief executive officer (CEO) in May 2010. In December 2010, Kalanick succeeded Graves as CEO and Graves became the chief operating officer.[8]

Following a beta launch in May 2010, Uber's services and mobile app launched publicly in San Francisco in 2011.[9][10] Originally, the application only allowed users to hail a black luxury car and the price was approximately 1.5 times that of a taxi.[11] In 2011, the company changed its name from UberCab to Uber after complaints from San Francisco taxicab operators.[12]

The company's early hires included a nuclear physicist, a computational neuroscientist, and a machinery expert who worked on predicting arrival times for Uber's cars more accurately than Google APIs.[6][13] In April 2012, Uber launched a service in Chicago, whereby users were able to request a regular taxi or an Uber driver via its mobile app.[14][15]
