Corridian debuts with $38 million seed round for underwater vehicle

Corridian debuted Nov. 3, 2026, with a $38 million seed round led by Point72 Ventures. The New England startup plans to unveil an ultra-large crewless underwater vehicle in 2027, designed to carry containerized payloads thousands of nautical miles. That range is a design goal, not a demonstrated result. Co-founder Mike Guay cited threats to ships and aircraft but did not disclose how the vehicle would launch.
