This simulation startup wants to be the Cursor for physical AI

Antioch, a robotics simulation startup, has raised $8.5 million in seed funding at a $60 million valuation led by A* and Category Ventures. The company builds simulation tools to help roboticists train autonomous systems by bridging the 'sim-to-real gap'—the challenge of making virtual training environments realistic enough that robots operate reliably in the physical world. Founded by Transpose/Chainalysis veterans, Antioch aims to make simulation a scalable alternative to building physical test facilities.
