Seasats develops autonomous surface vessels that can operate for weeks or months, tackling the “dull” but mission-critical tasks of persistent maritime surveillance, port security, and coastal patrol. Its flagship long-endurance craft has completed both trans-Pacific and trans-Atlantic crossings, while its interceptor platform has run continuous week-long operations, validating reliability and range. The company combines commercial manufacturing agility with defense-grade robustness to deliver cost-effective, scalable maritime autonomy. Demand is accelerating: Seasats has landed more than $100 million in U.S. government contracts, including awards from the U.S. Navy, U.S. Marine Corps, and the Department of War’s APFIT program. To date, the firm has raised over $40 million in venture funding. Fresh capital will expand production capacity, open new facilities, launch additional product lines, and grow the team to meet surging domestic and international interest. Headquartered in San Diego, Seasats positions itself as a key enabler of maritime domain awareness and risk reduction for both military and commercial customers.
