Position at Uber: Head of Global Customer Support Operations

Where she is now: Geidt started at Uber as an overdressed intern and employee number four; she says she struggled for the first months. At first, her job wasn’t well defined, and saw her moving from handing out flyers to passersby to cold-calling drivers.

In the past, she has also been open about her history with drug addiction and recovery.

Geidt has moved up as Uber has grown, and this week was promoted to head of global customer support operations.

Where he is now: Whelan was Uber’s first engineer and worked on “everything and the kitchen sink” after moving to San Francisco from his native Calgary, Canada. He built the sign-up flows that allowed Uber to actually have any users.

"Right now I'm focused on not focusing, but I am always looking for opportunities," he writes on his LinkedIn.

Position at Uber: Regional General Manager, US & Canada

Where she is now: After getting an MBA from Stanford, Holt decided to move across the country to DC to be with her boyfriend (now husband). She answered a job listing to launch Uber in DC and, 10 days later, Uber did its first DC ride. The market turned out to be one of Uber’s most combative and the first where it had regulatory issues. But Holt has stayed, and is now the regional general manager for Uber in the US and Canada.
