Emmett Shear

Emmett Shear is a technology entrepreneur best known as a co-founder and longtime CEO of the live-streaming platform Twitch (originally Justin.tv). He was part of Y Combinator's inaugural 2005 batch alongside Reddit's founders, placing him within the same early startup cohort that shaped Reddit's origins. He later became a part-time YC partner advising new startups, and in November 2023 served briefly as interim CEO of OpenAI during that company's leadership crisis. His direct, documented role in Reddit's corporate governance is limited, but he is frequently cited as a peer and contemporary of Reddit's founding circle.
