RadixArk is an AI infrastructure company spun out of the team behind SGLang, the open-source inference engine that serves trillions of tokens a day for the likes of Google, Microsoft, NVIDIA, Oracle and xAI. Founded by Ying Sheng and Banghua Zhu, RadixArk keeps SGLang and its reinforcement-learning framework Miles free and open while selling managed hosting and tooling on top, aiming to make building, training and running frontier models at least 10x cheaper and 10x more accessible. It launched publicly in May 2026 with a $100M seed round led by Accel and Spark Capital at a $400M valuation.
Genvid Holdings Inc. is a New York media-technology company that invented the Massively Interactive Live Event (MILE) - part TV show, part video game, where thousands of viewers vote on what happens next in real time. Founded in 2016 by Square Enix cloud-gaming veterans, Genvid has produced the Emmy-winning SILENT HILL: Ascension, the Webby-winning The Walking Dead: Last Mile, Rival Peak, and DC Heroes United. Backed by $166M in funding, the company is now extending its production infrastructure into studio-grade generative AI tooling for professional creators.
