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

Matt Carey, co-founder and CEO of Boston-based startup Teradar, thrives on skepticism. Recently, he shared that he welcomes the doubters, as they often lead to his most impactful demonstrations. After years of development, Carey has crafted a groundbreaking solid-state sensor that utilizes the terahertz band of the electromagnetic spectrum, positioned between microwaves and infrared light. This innovative sensor combines the advantages of traditional radar systems, such as durability and the ability to function in poor weather conditions, with the high-resolution imaging capabilities of lidar. Given that this technology is unprecedented at this scale, it's no surprise that potential customers express skepticism when they hear about it. However, demonstrations, such as those conducted at the Consumer Electronics Show in Las Vegas, have helped assuage doubts. There, Carey showcased an early version of the Teradar sensor, impressing representatives from major automotive manufacturers as it effortlessly analyzed crowds in real time. The successful demonstrations have propelled Teradar into the spotlight, culminating in a substantial $150 million Series B funding round. Investors include Capricorn Investment Group, Lockheed Martin’s venture arm, mobility-focused IBEX Investors, and VXI Capital, a newly established defense-focused fund led by a former CTO of the U.S. military’s Defense Innovation Unit. Teradar is currently collaborating with five leading automakers from the U.S. and Europe to validate its technology and aims to secure a contract for its sensors to be integrated into vehicles produced in 2028, necessitating readiness by 2027. In addition, Teradar is partnering with three Tier 1 suppliers for manufacturing support. The immediate objective is for automotive manufacturers to leverage these sensors for advanced driver-assistance systems and autonomous driving applications. Officially termed the “modular terahertz engine,” the sensor can be tailored for various uses, with pricing expected to be competitive—anticipated to be in the range of a few hundred dollars rather than the thousands typically associated with lidar systems. Carey’s motivation for founding Teradar stemmed from a personal tragedy; he lost a friend in a car accident that involved challenging environmental conditions—sun glare and fog—where existing sensors fell short. He recognized a gap in the market for a sensor that could effectively navigate these conditions, leading to discussions with Gregory Charvat, CTO of spatial sensor company Humatics, about leveraging terahertz technology. With Teradar's inception in 2021, supported by MIT’s The Engine incubation program, the company has made significant strides. While past efforts to exploit terahertz technology have primarily focused on industrial or security applications, Teradar aims to make its mark in the automotive sector. Recent advancements in silicon technology, combined with a dedicated team including co-founder Nick Saiz, a top terahertz chip designer, have accelerated their progress and attracted the attention of major automakers. Despite the challenges of engaging with the automotive industry, including securing funding and access to test tracks, Carey is optimistic. The company's recent successes in overcoming these hurdles signify a significant turning point—one that validates their ambitious vision for the future of automotive sensors.
