# Teradar

> Teradar is a Boston deep-tech company building the first commercial sensor that sees using the terahertz band of the electromagnetic spectrum - the slice between microwave and infrared. Its solid-state Modular Terahertz Engine combines radar's ability to punch through rain, fog and snow with resolution approaching that of lidar, claiming up to 20x the detail of today's automotive radar with no moving parts. Founded in 2020 and out of stealth in November 2025 with a $150M Series B, Teradar is working with eight global automakers and Tier-1 suppliers and aims to put its sensor in a production vehicle by 2028.

- **Founded:** 2020
- **Headquarters:** Boston, Massachusetts, United States
- **Founders:** Matthew Carey (Co-founder & CEO), Gregory Charvat (Co-founder & CTO), Nicholas Saiz (Co-founder & Chief Chip Architect)
- **Team size:** ~70 employees
- **Products:** Modular Terahertz Engine (MTE), Teradar Summit
- **Notable:** Built the first commercial sensing technology to image in the terahertz band of the electromagnetic spectrum., Exited stealth in November 2025 with a $150M Series B led by VXI Capital., Demonstrated native angular resolution as fine as 0.13 degrees - about 20x leading automotive imaging radar.

## Products & services

- **Modular Terahertz Engine (MTE)** — An all solid-state, customizable chip architecture - a set of proprietary chips that transmit, receive and process terahertz waves - that can be tuned to the range and resolution needs of any ADAS (L1-L2) or autonomous driving (L3-L5) system.
- **Teradar Summit** — Teradar's first terahertz vision sensor for vehicles, delivering native angular resolution as fine as 0.13 degrees - roughly 20x better than leading automotive imaging radar - with reliable, high-resolution 4D imaging in rain, fog and snow.
