Parallel Domain

Parallel Domain develops AI-powered simulation software that generates photorealistic neural reconstructions from real-world capture data for testing autonomous systems. The company offers two core products: PD Replica, which creates near pixel-perfect 3D reconstructions from drive or flight logs, and PD Sim, which provides deterministic sensor simulation across camera, lidar, and radar modalities. The platform enables teams to close the sim-to-real gap with measurable, auditable validation reports for regulatory readiness, and supports scenario variation across lighting, traffic, and weather conditions. Parallel Domain serves the automotive, drone, robotics, agriculture, trucking, and defense industries, integrating with existing autonomy stacks via API for closed-loop and open-loop testing. Founded in 2017 and headquartered in Palo Alto, California, the company has raised approximately $44.3 million in Series B funding from investors including Toyota Ventures, RRE Ventures, March Capital, and Foundry.
