Boston-based startup Teradar just emerged from stealth with a $150 million Series B and a bold claim: they've cracked the code on autonomous vehicle sensors. The company's breakthrough terahertz sensor promises to combine radar's all-weather reliability with lidar's high resolution at a fraction of the cost. With five major automakers already validating the tech and a 2028 vehicle launch target, Teradar could reshape how self-driving cars see the world.
Matt Carey's pitch sounds almost too good to be true. The Teradar CEO stands outside Vegas hotels, pointing his sensor at crowds while automaker executives watch skeptically. Then the magic happens - his device starts parsing the scene in real time using terahertz waves, that sweet spot between microwaves and infrared that nobody's commercialized at scale before.
"I don't believe you," they tell him. That's exactly where Carey wants them.
The Boston-based startup just pulled the curtain back on years of stealth development with a massive $150 million Series B round. Capricorn Investment Group led the funding alongside Lockheed Martin Ventures, mobility-focused IBEX Investors, and VXI Capital, a new defense fund helmed by the former CTO of the military's Defense Innovation Unit.
Carey's "modular terahertz engine" essentially cherry-picks the best features from existing sensor tech. It borrows radar's ability to slice through rain and fog without any moving parts, then adds lidar's high-definition imaging capabilities. The result is something the autonomous vehicle industry has been desperately hunting for - a sensor that actually works in all weather conditions without breaking the bank.
"How do we get the sensor on every single vehicle? I drive a Ford Focus, and there's zero chance you're putting a $1,000 lidar on that," Carey told TechCrunch. His sensors will price somewhere between radar and lidar - think hundreds of dollars instead of thousands.
The timing couldn't be better. Traditional sensors each have fatal flaws that have stalled autonomous vehicle rollouts. Cameras get blinded by sun glare and struggle in fog. Lidar costs too much and fails in harsh weather. Radar works in all conditions but lacks the resolution for precise object detection. Teradar claims its terahertz approach solves all three problems simultaneously.
The company's already working with five unnamed automakers from the US and Europe to validate the technology. They're targeting a 2028 model year vehicle launch, which means the sensors need to be production-ready by 2027. Three Tier 1 automotive suppliers are also in the mix for manufacturing partnerships.
Carey's personal motivation runs deeper than market opportunity. A close friend died in a car crash that he believes current sensor technology couldn't have prevented. "It was one of those weird corner cases where, between the sun and the fog, it couldn't have been solved by any existing sensor," he explained to TechCrunch.
That tragedy sparked conversations with Gregory Charvat, CTO of spatial intelligence company Humatics, about terahertz imaging possibilities. They launched Teradar in 2021 with MIT's The Engine nonprofit incubator leading the seed round. The third co-founder, Nick Saiz, brings what Carey calls world-class terahertz chip design expertise.
Teradar isn't the first company to experiment with terahertz technology. Academic research has explored the spectrum for years, with some commercial attempts focused on industrial and security applications. But recent silicon industry advances have finally made automotive-scale production feasible.
The defense sector interest is obvious from the investor lineup. Lockheed Martin doesn't typically back automotive startups unless they see broader applications. VXI Capital's involvement signals military and aerospace opportunities beyond passenger vehicles.
For now, Carey's keeping the focus laser-sharp on automotive applications. Getting automaker attention is brutally difficult, he admits. "It's very difficult to get their attention, it's very difficult to get their dollars, and it's very difficult to get their test track time. The fact that they've unlocked all of those things for us means a big deal."
The company's demo-heavy approach reflects the inherent skepticism around breakthrough sensor claims. The autonomous vehicle space is littered with companies that promised revolutionary detection capabilities but couldn't deliver at scale. Carey's betting that hands-on testing will convert doubters into believers.
With 2027 production deadlines looming, Teradar faces the classic startup challenge of scaling manufacturing while maintaining quality. The Tier 1 supplier partnerships suggest they're taking a pragmatic approach rather than trying to build everything in-house.
Teradar's $150 million bet on terahertz sensing could finally unlock the autonomous vehicle promise that's been perpetually two years away. By solving the weather and cost problems that have plagued existing sensors, they're positioning themselves as the missing piece in self-driving technology. The real test will be delivering production-ready hardware by 2027 while maintaining the performance that's impressed skeptical automaker executives. If Carey's demos translate to mass production, every vehicle on the road could soon see the world through terahertz eyes.
