Robotics simulation startup Antioch announced a $32 million Series A led by Greylock, with A Capital, Category VC, BoxGroup and Icehouse Ventures participating.

Antioch argues physical AI development has been constrained by slow, expensive hardware-based testing, and enables teams to build, test and validate systems at software speed. Customers include Amazon, Ring, NVIDIA Robotics and Nebius. The company is hiring across simulation, infrastructure, ML and 3D graphics.
