Shaun Maguire is Partner at Sequoia Capital. Formerly, Partner at GV. Growing up, I had a cousin who studied computer science at UCLA, who made a huge impact on me. When I was 7 years old, he helped me build my first computer. From the time I was 9, I’ve been obsessed with space. For months, when I was 13, I couldn’t sleep at night because there was a thought experiment I couldn’t understand. (It turns out space is curved.) I did horribly in high school. Bored out of my mind. I didn’t even go to class most of the time—1.8 GPA in 10th grade and an F in algebra II. I was doing projects on the computer, hanging out in hacker forums for 10 hours a day in IRC. I’ve started five companies. The first one was a failure, three of them have been successful, and one is too early to call. I started the second company with two friends and I got to know a lot of VCs raising money for it. I pitched everyone—except Sequoia, because they had a conflict. Fast forward a few years, and Google Ventures offered me a job that gave me the flexibility to stay in LA and finish my Ph.D. in quantum gravity. This wasn’t necessarily what I thought I would do long term. Then another fund that was trying to recruit me did a reference call with my friend Patrick Collison. Patrick called Sequoia and told them they should hire me instead.
