Uber announced Tuesday that it has added three new top executives to its ranks by combing the employee lists at Google, Facebook and Klout.

In a company blog post, Uber said that it has made three major hires: Former Google treasurer and chief accountant Brent Callinicos will now be the firm’s chief financial officer; Emil Michael, former chief operating officer of Klout, will join as its senior vice president of business; and Ed Baker, formerly head of international growth at Facebook, will become the car service’s head of growth. Michael and Baker will start in their positions immediately. Callinicos starts Monday.

The app-based car service is now in more than 40 cities worldwide, including the D.C. area.

Of course, it hasn’t been a completely smooth ride for Uber, which has run into its fair share of pushback from taxicab commissions, as well as local governments who have been wrestling with how to adjust or interpret their local rules to work with the car service.

That’s certainly been the case in D.C., where Uber and the D.C. Taxi Commission have had multiple disagreements, most recently about new restrictions on what counts as a “sedan.”

Regulation spats aside, the company recently announced that it had raised $258 million in funding from Google Ventures and TPG Capital, according to TechCrunch. Today’s hires show that the service — problems and all — has gained enough attention to attract talent from some of the industry’s most notable firms and that it’s not stopping its push for expansion any time soon.
