Antioch has raised $32M in a recent Series A led by Greylock, with A*, Category Ventures, BoxGroup, and Icehouse Ventures participating.

The company runs a cloud simulation platform that allows developers to turn robot testing from physical hardware into software.

The platform includes:

> Running NVIDIA's Isaac Sim and Isaac Lab code inside a local machine with no GPU, and then sending it to the cloud for processing as thousands of parallel replicas.

> An off-the-shelf module library covering 140+ robot models, 86 sensor models carrying noise and dropout, and 12 physics solvers that can be swapped per scenario.

> An agent layer that can onboard a robot from a CAD file, design the scenario suite, test it, and iterate on the failures.
