Traysar Secures $25M to Target Subterranean Military Threats
With over 10,000 hidden military facilities estimated to exist worldwide, the U.S. Army faces a growing blind spot beneath the Earth’s surface. Traysar, a new defense startup, emerged from stealth today with $25 million in seed funding to develop autonomous platforms capable of mapping and penetrating these subterranean networks.

The Detroit-based company, backed by lead investor Silent Ventures, aims to address a critical imbalance in modern defense spending. While global military investment has historically prioritized aerial and space-based assets, adversaries are increasingly turning to deep-earth bunkers and tunnel networks to shield command structures, nuclear sites, and logistics. Traysar’s engineering team—which includes alumni from SpaceX and The Boring Company—is building autonomous platforms designed for both tactical exploration and rapid subterranean access.
CEO Yadin Soffer stated that the company intends to close the long-standing capability gap that has left allied forces vulnerable to adversaries operating beneath the crust. The current technology suite includes excavator-class units for clearing contested tunnels and high-speed burrowing systems for delivering payloads or creating access points. Beyond offensive capabilities, Traysar is also marketing its technology to help secure allied manufacturing and critical infrastructure against strikes. The $25 million seed round also saw participation from Lux Capital, Ora Global, and various strategic angel investors, including Steve Blank and founders from Anduril.
