CEO of Getaround

Getaround is one of the startups everyone is talking about in Silicon Valley. Its CEO Sam Zaid is one of the most hard-working CEOs in the business and also made a very risky, but highly rewarding, early decision at Getaround: building all the hardware in-house.

Getaround is a car-sharing program which uses cars that are already on the road that owners are willing to share. The company has proved that people are certainly willing to share their cars in order to make some extra money, and the company just raised an extra $13.9 million.
