Cloud simulation platform for developing and validating autonomous robots: builders spin up parallel digital instances of their hardware connected to simulated sensors that reproduce the data streams the robot's software would receive in the real world, positioning itself as the 'Cursor for physical AI'. Founded 2025 in New York by five co-founders including ex-Tesla Autopilot engineer Harry Mellsop. Prior sim-only exclusion ground (Applied Intuition analog) voided — Applied Intuition now sits on the software register.
