Lassen Peak: Over $10 Million Raised To Bring Handheld Terahertz Radar Concealed-Weapon Detection To Market

By Amit Chowdhry • Jan 29, 2026

Lassen Peak announced it has completed a mix of debt and equity financings totaling more than $10 million to fund product completion and prepare for market introduction of what it describes as the world’s first fully integrated handheld radar system for concealed weapon detection.

The Bellevue, Washington-based company said the financings were led by Structural Capital, a Menlo Park firm focused on growth-stage venture and private credit. Lassen Peak said the package included venture debt from Structural Capital, along with additional capital from existing shareholders to support the company’s initial product launch.

Lassen Peak said other participating investors included AI Capital Partners, Lauder Partners, LionCrest Ventures, Madrona Ventures, Octave Ventures, and other strategic investors. The company also highlighted participation from Axon Enterprises, which it described as a leader in public safety technologies.

The company is developing a handheld system that applies submillimeter-wave terahertz imaging radar technology to detect concealed weapons in the field. Lassen Peak positioned the technology as an alternative to physical weapon searches, arguing that pat-downs can be dangerous and emotionally charged interactions that may escalate and result in injury or death, whether a weapon is present or not.

Lassen Peak said its solution is intended for use across law enforcement, military, and private venue security settings, and framed its mission around reducing the use of force while improving safety and trust in public safety interactions. The company described its team as bringing experience in ultra-high-speed wireless, imaging radar, artificial intelligence, and geolocation, and said it has assembled advisors and committee leadership with backgrounds in senior roles at law enforcement and civil rights organizations.
