Antioch Raises $32 Million Series A for Physical AI Simulation Used by Amazon and Nvidia

Greylock recently spearheaded a new investment into Antioch to expand the reach of simulation tools for robotics and autonomous systems. The $32 million Series A round will help the company scale its cloud scale infrastructure, which allows developers to create digital twins and generate synthetic data. Amazon Ring, Nvidia Robotics, and Nebius currently utilize the platform to run thousands of parallel tests before deploying code to physical hardware.

The software connects directly to CI/CD pipelines to act as a release gate for new robotics updates. Amazon says the results from these simulations closely match physical test data, including scenarios intentionally excluded from calibration, which allows teams to reproduce deployment failures in virtual environments to reduce the cost of hardware based development.
