Corridian, a Boston defence company building very large autonomous underwater vehicles, came out of stealth on 3 November 2026 with a $38m seed round led by Point72 Ventures.
Balerion Space Ventures, Harpoon Ventures, DCVC and Marlinspike joined the round with other defence and deep-tech investors. The company did not disclose its valuation. Law firm Fenwick said it advised Corridian on the financing.
The company was founded in September 2025 and is based in Boston. VC News Daily also reported the round.
“America's dependence on the surface and air domains to move mass at scale is an acute vulnerability,”Mike Guay, co-founder and CEO, Corridian
What Corridian is building
Corridian is developing what it calls ultra-large autonomous underwater vehicles. They are designed to carry standard ISO containerised payloads for thousands of nautical miles with no crew on board. The company calls the idea stealth logistics: moving military cargo below the surface, where it is harder to detect than on ships or aircraft.
Its first planned missions are delivering payloads and effects, intelligence, surveillance and reconnaissance, and resupplying forces in contested areas. Corridian said it will build its vehicles using aerospace-style manufacturing and a supply chain that does not depend on the shipyards that build US submarines. It plans to unveil its flagship vehicle in 2027.
Chief executive Mike Guay told Axios, as reported by The Next Web, that the platform would carry whatever payloads its customers chose.
The team
Guay founded the company with president Greg Barrow, chief technology officer Kyle Arace and chief operating officer Mark Bodnar. The four previously led one of the largest undersea autonomy portfolios in the United States at General Dynamics, with programmes in service with the US Navy and the Royal Australian Navy, the company said.
Retired Admiral Lisa Franchetti, the 33rd US Chief of Naval Operations, is the company's senior military adviser. Other advisers include Jason Potter, a former acting Assistant Secretary of the Navy for research, development and acquisition, retired Vice Admiral Jeff Trussler, retired Rear Admiral Milton "Jamie" Sands III and Stephen Rodriguez.
Chris Morales, a partner at Point72 Ventures and a former naval officer, said in the announcement that the founders had the knowledge and experience to pursue the opportunity.
Fenwick said its lawyer David T. Horne advised Corridian on the deal.
What the money is for
Corridian said it will spend the seed money on developing its flagship vehicle, building a research and development facility and hiring undersea engineers. The Next Web reported that it expects to double its workforce over the next year. It has not said how many people it employs now.
Franchetti said in the announcement that Corridian was addressing a real operational gap in a way that was both technically credible and scalable.
Rodriguez told Axios, as quoted by The Next Web, that he had backed the founders from the start because anything that can be observed is lost once fighting begins. The Next Web described him as a DCVC investor.
