ReSim
US virtual testing platform that runs parallel simulation, log replay, and hardware tests in the cloud for autonomous robots and vehicles.
ReSim is a simulation-based testing and evaluation platform for autonomous systems, founded in 2022 and led by CEO and founder Simon Box. The company is based in the United States with the CEO located in the San Francisco Bay Area. ReSim's core product allows robotics and autonomous vehicle development teams to run large numbers of virtual test scenarios spanning hardware tests, simulation runs, and log replays in parallel in the cloud, triggered on every code change and integrated with continuous integration and continuous deployment pipelines.
The platform supports three primary testing modalities: replay of recorded sensor logs from physical robots or vehicles with user-defined metrics attached; abstract simulation to evaluate behavioral logic; and rendering of realistic 3D environments to stress-test perception systems. Each test run automatically produces structured metrics output, giving engineers quantified visibility into how software changes affect system performance across a defined test suite. ReSim positions itself as infrastructure for safety validation and regression testing of autonomy stacks, replacing manual or ad hoc test processes with a scalable automated workflow.
The company has published integration documentation for NVIDIA Isaac Sim, describing how ReSim can orchestrate and analyze Isaac Sim-based tests at scale. Documented customers include Dexterity AI, a warehouse robotics company that used ReSim to accelerate development and gain visibility into robot performance across varied picking scenarios. ReSim has raised approximately $10.3 million in total disclosed funding from investors including A*, ANIM Fund, Five Two Five, Flybridge, and Fortitude Ventures among 11 total reported investors.
The platform is relevant across autonomous mobile robots, autonomous vehicles, drones, and other embodied AI systems where systematic regression testing against a large scenario library is required to reach reliability thresholds for commercial or safety-critical deployment.
