Joining the ride-hailing startup after battling a drug addiction, Geidt was the fourth hire at Uber and has been with the company ever since.
"I'm so proud of the work my team has done at Uber and the work I've done at Uber. But it's not the proudest thing I've done, right? I'm more proud of being sober," she said at a Fortune conference. "I just have perspective."
As Head of Global Expansion, she's taken Uber from one city to more than 100 and plots on a map where Uber is going next. If that wasn't enough of a job, she also oversees the PRO team, Uber's equivalent to business ops, that's in charge of streamlining the company. One of her special projects is Uber's 1 Million Women initiative to sign up one million women to the platform by 2020.
