Antioch Raises $32 Million Series A to Expand Physical AI Simulation

Physical AI simulation company Antioch said it has raised $32 million in a Series A round led by Greylock, with participation from A* Capital, Category Ventures, BoxGroup, Icehouse Ventures, and angel investors. According to ChainCatcher, the company provides simulation tools for physical AI teams to build, test, and validate systems. Antioch said AI has accelerated software development, but physical autonomous systems remain constrained by slow and costly hardware development. The company said its customers and partners include Amazon Ring, NVIDIA Robotics, and Nebius. Antioch also said it is expanding rapidly and is hiring for roles in simulation, infrastructure, machine learning, 3D graphics, market, and operations.
