Physical AI simulation startup Antioch raises $32M, ships browser-based robot eval suite
testingcatalog · x · 2026-09-08
Antioch has raised $32 million to bring software-speed iteration to physical AI development.
Its Antioch Agent, shipped in June, runs the full workflow in the browser: import a robot, build the scene, generate the test suite, and read pass rates. The platform offers cloud-scale, high-fidelity simulation across the physical AI lifecycle:
- Development: digital twins with interactive simulation
- Evaluation: thousands of simulated scenarios (e.g., quadrotor shipyard landings under 8-18 m/s crosswinds)
- Synthetic data generation
A sample dispatch runs 2,048 replicas for an estimated $4.10 and integrates with CI/CD for full test coverage per release. Use cases span aerial, industrial, and ground autonomy.
