Congruent builds AI-native radar sensors designed for autonomous vehicle systems. The company develops both hardware that exposes raw radar data and a world-model-based simulator for driving scenarios. Its technology enables end-to-end neural network training for self-driving cars, addressing the gap where existing automotive radars output heavily processed data without simulation capabilities. Congruent was founded in 2025 and is a Y Combinator Winter 2026 company based in San Francisco.
