Subsea Cloud Inc.

What Subsea Cloud Inc. does

Subsea Cloud Inc. is a deep-technology company founded in 2021 and headquartered in Houston, USA, with offices in the UK and Norway. It designs, builds, deploys, and maintains subsea data centers that sit on the seafloor and use passive immersion cooling — servers are submerged in non-conductive dielectric fluid and cooled through the surrounding seawater, eliminating electrically driven cooling. The company's core product is a modular 20ft x 8.5ft container housing 16 racks (approximately 826 servers), rated at 0.5-1.5MW per unit with 125kW per-rack density, deployable at depths from 10ft to 9,500ft (3,000M) with a 25-30 year design lifespan and a 3-5 year server refresh cadence. Each unit integrates with existing subsea telecom cables and offshore power infrastructure, including co-location with offshore renewable generation. Reported performance metrics include a Power Usage Effectiveness of 1.01, claimed 50% greater efficiency vs. land-based facilities, ~$1M CAPEX per 1MW vs. ~$7M on land, up to 80% TCO improvement, and up to 40% OPEX reduction when co-located with renewable power.

The go-to-market is a direct enterprise sales motion targeting eight named vertical segments: AI start-ups, independent and national ISPs, LEO satellite operators, neo-cloud providers, cloud providers, legacy offshore asset owners, offshore renewables operators, and subsea cable owners. Pricing is quote-based and not publicly disclosed. Revenue is generated through multi-year subscription leases of data center units, one-time outright purchases of modular units (treated as amortized capex with residual value), and managed power-and-connectivity services where clients bring their own servers. Project OTTO, launched in October 2024 in South-West Norway, is a rolling 30/60/90-day trial program billed for space and power with cooling, security, and backup/recovery provided at no charge, serving as the company's primary customer-acquisition mechanism.

The company is privately held with 11-50 employees and no disclosed venture capital funding rounds. The ownership structure is not publicly disclosed. Distribution is global in principle (any location with water, power, and subsea telecom infrastructure), but disclosed operational footprint is limited to the USA, UK, and Norway. Strategic partnerships have been formed across cable owners, renewables operators, cloud providers, and legacy offshore asset owners to anchor site and power access for future deployments. As of 2022, the company had transitioned from initial testing to a commercial testing phase with both non-commercial private deployments and commercial trials in operation.

Revenue model

1. Data Center Unit Leasing: Lease terms with shorter base terms compared to traditional 7-10 year terms, with ramp rights, renewal options, and portfolio portability. Includes space, power, cooling, and in some instances servers.
2. Data Center Unit Sales/Purchasing: Buying modular units outright lowers long-run TCO by turning monthly fees into amortized capex with residual value. Factory-built units deploy fast and scale predictably.
3. Power and Connectivity Services: Clients can bring their own servers and rent power, space and connectivity. Subsea Cloud provides the infrastructure while clients manage their own hardware.
4. Project OTTO Trial Program: Rolling trial program where participants are billed for key components such as space and power. No charges for cooling costs, security or backup and recovery.

Core offering

Subsea Cloud Inc. designs, builds, deploys, and maintains modular subsea data center pods placed on the seafloor. Servers are submerged in non-conductive fluid with passive cooling provided by surrounding ocean water, eliminating electrically driven cooling. The company offers these units via outright purchase or multi-year lease, bundled with lifecycle services including assessment, design and engineering, deployment, remote monitoring, and retrieval.

Product overview

Subsea Cloud Inc. offers a unified subsea data center platform consisting of modular DC units (pods) deployed on the seafloor and a comprehensive lifecycle management platform. The core offering is the Subsea Data Center Units—standardized containers designed for 25+ years of service with passive immersion cooling, zero water use, and AI/ML-ready compute. The Subsea Data Centers Platform supports the full deployment lifecycle from assessment through retrieval. Project OTTO serves as a pilot trial program allowing prospective clients to test the technology before committing to full-scale commercial deployments. All products leverage natural seawater cooling to eliminate electrically driven cooling, achieving PUE of 1.01 and reducing carbon emissions by 40% compared to traditional data centers.

Others

• SubCom: Leading subsea cable installation and maintenance provider. Functions as both a potential deployment and maintenance partner for Subsea Cloud and an adjacent infrastructure player serving the same subsea ecosystem.
• Green Revolution Cooling: Provider of single-phase immersion cooling solutions for high-density data centers. A technology enabler in the same cooling-adjacent space as Subsea Cloud, and a potential component supplier or design partner rather than a direct competitor.

Emerging players

• CoreWeave: AI-focused neocloud built on GPU infrastructure, representing both a key customer segment for Subsea Cloud and a potential competitor for AI compute workloads. CoreWeave's land-based scale and rapid growth set the benchmark Subsea Cloud must beat on time-to-deploy.
• Lambda: GPU cloud provider serving AI developers and enterprises. Lambda overlaps with Subsea Cloud's AI startup and neo-cloud customer segments and is a potential partner or competitor for high-density compute capacity.
• Crusoe Energy: Sustainable cloud computing provider that pairs AI compute with stranded and renewable energy. Competes for the same sustainability-led AI customer base and shares Subsea Cloud's positioning around ESG-friendly infrastructure.

Broad incumbents

• Equinix: Global colocation and interconnection leader operating hundreds of IBX data centers worldwide. Equinix is the dominant incumbent for the AI, cloud, and enterprise workloads that Subsea Cloud targets, though it builds on land rather than subsea.
• Digital Realty: Major global data center REIT operating hyperscale and colocation facilities across the Americas, EMEA, and APAC. Represents a large, well-capitalized incumbent competing for the same AI and cloud customer wallet.
• EdgeConneX: Specialist in edge data centers, deploying capacity close to end users. EdgeConneX addresses the same latency-sensitive, coastal-deployment use cases that Subsea Cloud targets, and represents an incumbent alternative for ISP and edge customers.

Direct peers

• Nautilus Data Technologies: Developed water-cooled data center solutions using a barge-mounted design, directly competing in the water-based cooling space. Though Nautilus eventually pivoted away from the offshore approach, it is the closest historical competitor to Subsea Cloud's model.
• Microsoft (Project Natick): Microsoft's Project Natick (2014-2020) deployed and operated a subsea data center off the coast of Scotland, validating the core technical premise of Subsea Cloud. While Microsoft wound down the program, the engineering learnings and operational data are the most direct precedent for Subsea Cloud's approach.
