Ryan Graves was the first employee hired at Uber, the ride-hailing service now valued at $41.2 billion. Uber is competing with taxi services across the U.S. and in 53 other countries around the world. The often-controversial company is banned in several countries including Spain and was temporarily banned in India as it battles regulators and safety concerns. In early 2015 the company said it would step up its cooperation with city governments in Europe, where it plans to grow. Graves joined Uber in 2010 when Travis Kalanick, Uber’s cofounder and current CEO, tweeted that he was looking for a product manager.
