Antioch announced a $32M Series A led by Greylock, with A, Category Ventures, BoxGroup, Icehouse Ventures and angels participating.

Its pitch: AI has accelerated software development, but physical AI is still constrained by slow, expensive hardware-based testing. Antioch lets teams build, test, and validate embodied systems in scaled, high-fidelity simulation at the speed of software. Customers already include Amazon Ring, NVIDIA Robotics, and Nebius.
