Traysar, an Austin, Texas-based subterra defense tech company, has raised $25 million in a Seed funding round led by Silent Ventures.

The round also saw Lux Capital, Ora Global, NeverLift VC, Mana, Impatient Ventures, New Vista, Entree Capital, and angel investors, including Steve Blank and founders from Anduril and Erebor, among others.

The company plans to use the funding to expand its operations and support further product development.

Traysar’s engineering team, which includes former engineers from SpaceX and The Boring Company, is developing autonomous underground systems designed for navigation and operation in challenging environments.

Its first platform is an excavator-sized autonomous vehicle that can quickly move through, map, and clear underground tunnel networks while supporting tactical exploration missions.

Underground infrastructure is often used to protect critical assets such as missiles, leadership facilities, and command centers. The same underground environment can also help allied forces strengthen military bases, secure manufacturing operations, and maintain supply chains during attacks. Traysar develops technologies designed to support both underground defense and infrastructure protection.

Underground threats are becoming a growing concern around the world. According to a 2023 report to Congress, China has invested heavily in underground facilities to protect key military assets. Other countries, and groups have also built deep underground networks making them difficult to monitor or target. Cross border tunnels have become a security challenge in several regions including the United States.

At the same time, much of global defense spending is focused on air and missile systems, drones, and counter-drone technologies. As adversaries continue to expand underground infrastructure, there is increasing recognition that underground environments are becoming an important strategic area for defense and security.

"For decades, we have allowed a massive capability gap to widen beneath our feet," said Yadin Soffer, Co-Founder and CEO of Traysar. "Our message to adversaries is clear: there is no place to hide. Traysar's mission is to expose every subterranean threat and equip the armies of the free world to fight in this new-yet-ancient dimension."

"Traysar is pioneering the doctrine and developing the technology required for U.S. military supremacy across the subterranean domain, a war-fighting realm steeped in history dating back to WWI, through the Vietnam Conflict, and is now quickly emerging as the defining 21st century battlefield," said Jackson Moses, GP at Silent Ventures, whose seed investments include Saronic and Castelion.
