What Subsea Data Systems does

Subsea Data Systems, Inc. is a U.S. privately held deep-technology company founded in 2021 as a partnership between Samara/Data and Ocean Specialists, Inc., with headquarters in Washington, D.C. and additional offices in Florida and Silicon Valley. The company designs and deploys the Universal SMART (Sensor Monitoring And Reliable Telecommunications) Cable platform — a low-power, modular sensing system that embeds research-grade environmental sensors (3-axis accelerometer, Paroscientific absolute pressure gauge, Sea-Bird glass-coated thermistor) inside subsea cable repeaters or in standalone pressure housings, and that works across repeatered, unrepeatered, and purpose-built submarine cable architectures. Its first universal sensor system was deployed at Ocean Networks Canada's NEPTUNE Observatory Cascadia node in September 2025 and announced as operational in February 2026, transmitting real-time seismic, pressure, and temperature data to the NSF National Geophysical Facility and ONC's Oceans 3.0 open-access portal.

The product portfolio spans SMART Repeater and SMART Sensor System hardware, paired with the STRATA Observer data management and alerting platform and STRATA Relay API-driven integration layer. The company monetizes through hardware sales to telecom operators and cable owner/operators, project-based custom integration services, and recurring STRATA Observer subscriptions; it is also supported by grant-funded R&D from NSF SBIR, Schmidt Marine Technology Partners, and the Gordon and Betty Moore Foundation. Customers and collaborators span U.S. and international federal science agencies (NSF, NOAA, NASA, DoD, ITU/WMO/UNESCO-IOC), ocean research institutions (Ocean Networks Canada, University of Hawai'i at Mānoa), defense and critical infrastructure stakeholders, and telecom operators, with active geographic engagement across North America, Europe, the Asia-Pacific, and polar regions.

Leadership comprises President and Co-Founder Matt Fouch, Ph.D., a former tenured geophysicist and Presidential Early Career Award recipient who serves on the ITU/WMO/UNESCO SMART Cables Joint Task Force, and CTO and Co-Founder Stephen Lentz, a 25-year submarine cable systems veteran. The company markets primarily through direct enterprise and government sales supported by heavy conference-circuit presence (SubOptic, Subsea NEXUS, PTC, Submarine Networks EMEA/World, AGU, Arctic Circle Assembly) and standards-body engagement rather than paid digital channels. Pricing is project-based for hardware and tier-based subscription for software, with no publicly disclosed list prices.

Core offering

Subsea Data Systems designs, builds, and deploys the Universal SMART (Sensor Monitoring And Reliable Telecommunications) Cable sensor platform — research-grade environmental sensors (3-axis accelerometer, absolute pressure gauge, glass-coated thermistor) embedded inside subsea cable repeaters or deployed as standalone units on repeatered, unrepeatered, and purpose-built submarine cable systems. The hardware feeds the STRATA Observer and STRATA Relay data management software stack, which delivers live visualization, alerting, and API-driven integration of seismic, pressure, and temperature data to telecom operators, federal agencies, and research institutions.

Product overview

Subsea Data Systems delivers the full SMART Cable stack end-to-end, organized as a platform-plus-modules architecture. The hardware layer consists of the SMART Repeater (sensors embedded inside subsea cable repeaters for telecommunications cable systems) and the SMART Sensor System (a standalone universal platform deployable on repeatered, unrepeatered, and purpose-built cable systems, currently operational in prototype on Ocean Networks Canada's NEPTUNE Observatory). The data/software layer is the SMART Data Management line, comprising STRATA Observer (live SMART Cable data management, visualization, and alerting) and STRATA Relay (custom-configured data integration and active response pipelines for customer operational workflows). The two layers fit together as full-stack sensing: seafloor hardware (SMART Repeater / SMART Sensor System) feeds continuous, real-time seismic, pressure, and temperature data to surface-level intelligence (STRATA Observer / STRATA Relay), available either as a standalone system or via API-driven integrations into customer platforms.

It is comparable as a broad incumbent capable of entering or partnering in the SMART Cable sensor market.
• Teledyne Marine: Teledyne Marine is a diversified supplier of subsea imaging, sonar, and sensor systems used across oceanographic, defense, and infrastructure-monitoring applications. It is comparable as a broad incumbent in the deep-ocean sensing market that SDS addresses.

Direct peers

• AP Sensing: AP Sensing provides distributed fiber optic sensing (DTS/DAS) for cable health and environmental monitoring along terrestrial and submarine infrastructure. It addresses the same buyer need (continuous cable monitoring and threat detection) with a competing technology approach.
• OptaSense (Luna Innovations): OptaSense, a Luna Innovations company, is a leading provider of distributed acoustic sensing (DAS) used for pipeline, perimeter, and submarine cable monitoring. It competes for the same cable-health and domain-awareness budgets that drive demand for SMART Cable sensor packages.
• Ocean Specialists, Inc. Ocean Specialists, Inc. is a submarine cable engineering consultancy that is both a founding partner of Subsea Data Systems (joint venture with Samara Data) and a comparable independent integrator of subsea cable programs. It is comparable because it operates in the same project delivery layer for submarine cable deployments.

Others

• Battelle: Battelle is a major science and technology R&D organization that jointly showcased SMART Cable sensor system developments with SDS at the 2024 Arctic Circle Assembly. It is comparable as an adjacent ecosystem participant and collaborator in subsea environmental monitoring.
