What Nautilus Data Technologies does
Nautilus Data Technologies is a private, venture-backed designer and manufacturer of liquid cooling infrastructure for high-density, AI-oriented data centers. Founded in 2013 and headquartered in San Ramon, California, the company sells a product family branded EcoCore that includes the XCD ultra-capacity containerized cooling distribution unit (up to 15MW of heat rejection per module), the FCD facility-wide CDU (up to 4.1MW), the RCD in-row CDU (up to 3.9MW in 1.2 m²), and EcoCore Infrastructure — prefabricated modular data center blocks of 2.5MW or 4MW that integrate mechanical, electrical, plumbing, structural, and data hall components. Its proprietary water-based heat sink approach is paired with a patented vacuum-based Leak Prevention System (LPS), produces a power usage effectiveness of approximately 1.15, and is compatible with freshwater, saltwater, graywater, and industrial water sources, allowing deployments to draw on natural water bodies without chillers or cooling towers.
The company has historically operated its own floating data centers, most notably a 7MW facility at the Port of Stockton, California, commissioned in 2021, which has accumulated more than 500,000 unit hours of fully liquid-cooled operational experience. In 2024 Nautilus pivoted from building its own data centers to selling modular cooling infrastructure to third-party developers, launching the EcoCore product line and beginning deployments such as a 12MW installation at Start Campus's SINES facility in Portugal. Revenue is generated primarily through direct enterprise sales of CDU hardware and prefabricated infrastructure blocks, supplemented by colocation services at Stockton, channel sales via a partnership with LNPG, and a co-development relationship with Hitachi for floating data center designs. Customers are predominantly AI companies, hyperscalers, neoclouds, colocation operators, and large enterprises with HPC workloads, and the company cites multi-year enterprise contracts, ISO 27001, SOC 2 Type II, HIPAA, and NIST 800-171 attestations, and a portfolio of 15+ US patents plus international filings in GB and SG.
