Chris is CTO and Founding Engineer of Reddit. Though a software engineer by vocation, his first attempt at a career started with his finishing a PhD in experimental physics at Harvard where he learned about the importance of modeling, critical thinking, statistics, and (honestly) welding. He uses the first three skills regularly. The final years of his PhD were concurrent with him breaking into startups and getting accepted to the first YCombinator class, where he subsequently met Steve and Alexis and became Reddit's first employee five months into the company. After five years at Reddit, he left with Steve to work on Hipmunk as Chief Scientist. He's been back at Reddit for 18 months and has just transitioned to CTO after a year as Director of Engineering.

Torsten Reil is the founder and former CEO of NaturalMotion, a UK-based games and technology company spun out of Oxford University. NaturalMotion's AI-based animation technology powers some of the biggest blockbuster movies (e.g. Lord of the Rings) and video games (such as GTA IV and V). In 2011, the company started developing its own game IP, resulting in the largest racing franchise on mobile (the 200m-user CSR Racing) and the award-winning Clumsy Ninja. In 2014 NaturalMotion was acquired by Zynga for $527m.
