Teradar raises $150M for a sensor it says beats lidar and radar

Teradar, a Boston-based startup led by CEO Matt Carey, has developed a novel solid-state sensor that operates in the terahertz band of the electromagnetic spectrum, positioned between microwaves and infrared. This sensor aims to combine the advantages of radar—such as no moving parts and effective operation in adverse weather conditions—with the high resolution typically associated with lidar. Teradar claims its sensor offers long-range, high-resolution detection at a price point between radar and lidar, making it more affordable for widespread automotive use. The company has demonstrated the technology publicly, including at CES, where it impressed major automakers with real-time scene parsing. The startup recently secured $150 million in Series B funding from investors including Capricorn Investment Group, Lockheed Martin’s venture arm, IBEX Investors, and VXI Capital. Teradar is collaborating with five leading U.S. and European automakers and three Tier 1 suppliers, targeting sensor integration in 2028-model vehicles, with production readiness expected by 2027. The
