Teradar Secures $150 Million Series B to Advance All-Weather Terahertz Vision Sensors for Autonomous Vehicles
Teradar, a Boston-based startup pioneering terahertz vision sensor technology, has dramatically increased its financial backing through a $150 million Series B funding round, underscoring robust investor confidence in its mission to revolutionize automotive sensing and perception systems. The financing will help the company accelerate commercialization of its solid-state terahertz vision sensor, which combines the weather-penetrating strengths of radar with the high resolution of lidar to offer unprecedented all-weather perception for advanced driver assistance systems (ADAS) and future autonomous vehicles.
Emerging from stealth in November 2025, Teradar’s Series B was led by VXI Capital, a venture firm with defense and advanced technology expertise that supports innovation in foundational systems. Alongside VXI Capital, the round saw participation from IBEX Investors, Capricorn Investment Group, The Engine Ventures—the venture arm affiliated with MIT’s nonprofit innovation ecosystem—and Lockheed Martin Ventures, the corporate venture arm of the global aerospace and defense leader.
Teradar’s funding milestone positions it at the forefront of a new generation of sensing technologies designed to overcome fundamental limitations of existing sensors. Traditional radar systems, while robust in poor weather and visibility conditions, lack the resolution needed for fine object recognition. Lidar, meanwhile, delivers high-resolution mapping but suffers from drift in fog, rain, and snow and comes with high cost and mechanical complexity. Teradar’s terahertz (THz) vision technology operates in a frequency band between radar and infrared and is engineered to deliver up to 20 times the resolution of conventional automotive radar while maintaining reliable performance in challenging environmental conditions.
The company’s flagship hardware architecture, the Modular Terahertz Engine (MTE), is an all-solid-state, customizable chip designed to provide long-range perception without moving parts—reducing costs and mechanical complexity compared with many lidar systems. This solid-state design, which Teradar has demonstrated to representatives from multiple top automakers, aims to meet the perception needs of both production ADAS and future autonomous driving platforms.
Teradar is already collaborating with five major automakers in the United States and Europe as well as three Tier 1 automotive suppliers to validate its sensor and advance toward volume manufacturing. The company expects its terahertz vision sensor to be production-ready by 2027, with the goal of being integrated into vehicles as early as the 2028 model year.
According to company leadership, Teradar’s sensor offers a compelling value proposition that could both complement and supplant current radar and lidar solutions. By providing high-fidelity perception in all weather conditions—such as fog, rain, snow, and glare—at potentially lower costs than many lidar units, the technology could accelerate adoption of safety and automation features across a broader range of vehicle segments, not just premium models.
Beyond automotive markets, Teradar’s terahertz vision technology has broader implications for sectors including defense, industrial automation, and robotics, where resilient and high-resolution sensing is critical. The involvement of Lockheed Martin Ventures and VXI Capital underscores the potential applicability of Teradar’s sensor capabilities for defense systems that require advanced situational awareness and target detection in varied environments.
The Boston-based company was founded in 2021 by a team with deep expertise in sensor systems, electromagnetics, and chip design. Under the leadership of Matt Carey, Co-Founder and CEO, and co-founders including Gregory Charvat (CTO) and Nicholas Saiz (Chief Architect), Teradar has rapidly advanced from concept to commercialization readiness, attracting significant investment and strategic partnerships along the way.
Investor enthusiasm and Teradar’s rapid progress reflect growing demand for resilient perception systems in an era where autonomy, safety, and robustness are paramount. As legacy sensor technologies grapple with environmental limitations and cost pressures, Teradar’s terahertz vision sensor could redefine how vehicles perceive the world around them while offering a scalable path to enhanced safety and automation.
With substantial capital in hand, Teradar is poised to scale its manufacturing and commercial deployments, deepen collaborations with automakers and suppliers, and further refine its technology for broad adoption across transportation and other high-performance sensing applications. The company’s vision of delivering dependable, high-definition perception in all conditions underscores a transformative step toward safer roads and more capable autonomous systems.
