Skild AI is a Pittsburgh-based robotics company building the Skild Brain, a single general-purpose foundation model designed to control any robot - quadrupeds, humanoids, tabletop arms, mobile manipulators - across many tasks without bespoke retraining. Founded in 2023 by former Carnegie Mellon professors Deepak Pathak and Abhinav Gupta, the company trains on a mix of large-scale simulation, internet video, teleoperation and real-world deployment data. After a $1.4B Series C in January 2026, Skild AI is valued at over $14 billion.
