Corridian has emerged from stealth with $38 million in seed funding to develop large autonomous underwater vehicles capable of transporting military cargo and other payloads across thousands of nautical miles without a crew. The round was led by Point72 Ventures, with participation from Balerion Space Ventures, Harpoon Ventures, DCVC, Marlinspike and other defense and technology investors. The funding will support development of Corridian’s first autonomous underwater vehicle, expansion of its research and development facility and hiring for its undersea engineering team, with a flagship model planned for unveiling in 2027. The New England defense technology company is designing vehicles to carry large payloads in standard shipping containers through contested waters while remaining difficult to detect, with initial development efforts focused on military cargo delivery, intelligence gathering, surveillance and reconnaissance. Corridian plans to use suppliers outside the traditional submarine industrial base. Founded in September 2025 by former General Dynamics executives Mike Guay, Greg Barrow, Kyle Arace and Mark Bodnar, the company is led by Guay as CEO, Barrow as president, Arace as chief technology officer and Bodnar as chief operating officer.
