About
About Antioch
Antioch creates calibrated digital environments from customer assets and operating conditions, then runs robot or autonomy software against them through cloud infrastructure. Teams can execute many scenarios in parallel, inspect failures and vary environmental or behavioural conditions without occupying the physical machine.
Its 3D-aware agents are intended to generate and interact with realistic test situations rather than replay only fixed scripted scenes. Antioch remains an early-stage platform serving robotics and autonomy development teams, with its value centred on accelerating validation before field deployment rather than replacing final hardware testing.

Timeline
Events
- 2026-09-08 - Funding - Antioch raises $32M Series A led by Greylock
Greylock partner Saam Motamedi joined the board. Antioch identified Amazon Ring and Launchpad Build AI as users of its simulation platform. The company is hiring across simulation, machine learning, infrastructure, graphics, go-to-market and operations.
Source - 2026-04-16 - Funding - Antioch closes $8.5 million seed round to expand simulation platform for autonomous systems
Antioch raised $8.5 million in seed funding to expand its cloud-based simulation platform for robotics and autonomous systems. The company said the platform lets autonomy teams create digital twins, run large-scale simulated validation, and reduce dependence on expensive real-world testing environments. Antioch positioned the round around accelerating software-native testing and deployment workflows for physical AI systems.

Antioch emerged publicly as a New York startup building cloud simulation infrastructure for robotics and autonomous systems teams. The company was founded in early 2025 by former autonomy engineers and positioned around software-native validation, digital twins, and large-scale simulated testing. Antioch framed its platform around reducing the cost and operational burden of real-world robot testing.

Antioch raised a $4.25 million pre-seed round to build cloud simulation infrastructure for robotics development. The company said its platform allows autonomy teams to define robot stacks in software, validate them in high-fidelity simulation, and carry those workflows into deployment. Antioch said it had integrated with NVIDIA Omniverse, NVIDIA Cosmos, and Foxglove as part of its simulation and observability stack.
