The Problem
Emmett Shear founded Softmax in 2024 with a specific technical thesis about AI alignment — the problem of getting powerful AI systems to behave in ways that are actually good for humans, not just superficially compliant with instructions. His public writing and podcast appearances have described the work as focused on the fundamental research and engineering questions behind aligning frontier systems, drawing on ideas from evolutionary biology and multi-agent coordination.
The founding case, in his own framing during interviews on the Lex Fridman podcast and elsewhere, was that alignment was the most important technical problem in AI and that too little serious work was being done on it relative to capabilities work.
The Journey
Shear's earlier career was as a consumer-internet founder. He co-founded Justin.tv in 2007 with Justin Kan, Michael Seibel, and Kyle Vogt out of Y Combinator. Justin.tv began as a single-person livestream experiment and evolved into a general streaming platform. The gaming vertical, spun out as Twitch in 2011, grew into one of the largest consumer internet products of the decade. Amazon acquired Twitch in 2014 for approximately $970 million, per widely-reported coverage.
Shear served as Twitch's CEO through the acquisition and continued in the role until March 2023, when he stepped down. He remained active in the startup ecosystem as a Y Combinator visiting group partner and investor.
