Nautilus Data Technologies is a California-based data center operator that pioneered waterborne, water-cooled facilities as a lower-PUE alternative to conventional inland builds. Founded in 2013, it spent nearly a decade developing its patented Total Treated Water Cooling System before commissioning Stockton One, a 7 MW barge-mounted colocation facility in the Port of Stockton, California, which came online in 2021 and remains its flagship reference site. The company reports Stockton One operates at a PUE of roughly 1.05, well below the industry average, by drawing river or seawater through a closed heat exchange loop rather than running mechanical chillers. The business has pivoted to the AI infrastructure wave, positioning its EcoCore liquid cooling product line (in-row, facility-wide, and containerized CDU variants scaling to 10 MW per module) as a retrofit path for AI factories. In 2026 NVIDIA named Nautilus a certified AI Factory Infrastructure Partner, and the company has publicly discussed expansion sites in Ireland and Maine, though capacity and timing for those projects have not been disclosed. Nautilus remains privately held, with historical backing tied to founder Arnold Magcale and a series of undisclosed strategic and infrastructure investors.
