Sea Machines Robotics

What Sea Machines Robotics does

Sea Machines Robotics, founded in 2015 and headquartered in Boston, Massachusetts, builds autonomous command-and-control systems and unmanned surface vessels (USVs) for commercial maritime and defense customers. Its core product stack centers on the SM300 and SM300-SP autonomy systems, the proprietary TALOS software for autonomous navigation and vessel control, the AI-ris 4K computer vision module, and the JETsense family of intelligent voyage control products, supported by the FleetViewer fleet management interface and the SMLink APIs. Hardware platforms include the SELKIE and STORMRUNNER USVs, and the company also offers the SM200 wireless helm. Underlying technology relies on an in-house maritime perception model trained on SeaSAW, claimed as one of the largest maritime perception datasets, and the systems carry ABS, Bureau Veritas, and U.S. Coast Guard certifications for safety-critical marine use.

The company makes money by selling and integrating autonomy kits and USV platforms directly to commercial fleet operators (workboats, shipping, passenger ferries) and to government/defense agencies and prime contractors. Pricing ranges from lower-ticket perception products (AI-ris listed at $27,900) to multi-hundred-thousand-dollar autonomy installations and USV platforms priced at the high six to low seven figures. Go-to-market combines direct sales for U.S. defense and commercial accounts with a global channel of OEM and integrator partners, including St. Johns Ship Building, HamiltonJet, Leonardo DRS, Scientific Systems, and Shintoa Corporation. Cumulative deliveries exceed 200 systems across more than 20 countries, and the company is scaling to 100+ units/month of production capacity.

Customer concentration is balanced between defense (U.S. Navy, U.S. Marine Corps, U.S. Army via Leonardo DRS, NOAA) and commercial (Maersk, Foss Maritime), and the investor base includes strategic backers such as Toyota Ventures, Huntington Ingalls, Brunswick, Emerald Technology Ventures, and Nabtesco Technology Ventures, alongside Accomplice, with cumulative funding above $55M. The company reported 10x year-over-year booking growth, 80% higher deal volume, and 100% higher average deal size through mid-2026, indicating a sharp growth inflection driven primarily by defense program wins.

Core offering

Sea Machines Robotics builds autonomous command and control systems for commercial marine and boating industries. The company's flagship SM300 hardware-software system (available in SM300-SP and SM300-NG variants) powers vessel-agnostic autonomy for vessels from 10 to 300 feet, integrating radar, AIS, GNSS, IMU, depth sensors, weather data, and proprietary AI-ris computer vision. Sea Machines also produces two purpose-built unmanned surface vessels — SELKIE (7m survey vessel) and STORMRUNNER (8m tactical AUSV) — along with SMLink APIs, the FleetViewer cloud platform, and AI-ris 4K vision sensors for both commercial and defense customers.

Product overview

Sea Machines Robotics offers a comprehensive maritime autonomy portfolio comprising two hardware-based autonomy systems (SM300-SP and SM300-NG) that serve as the core command and control platforms for vessels ranging from 10ft RHIBs to 300ft workboats. The company also manufactures two purpose-built USV platforms: SELKIE (7m versatile modular vessel) and STORMRUNNER (8m tactical contested-environment vessel). Supporting software includes SMLink Streaming-API and SMLink Control-API for third-party integration, FleetViewer for fleet monitoring, and AI-ris for computer vision enhancement. The SM200 wireless helm system provides remote vessel control capability. All products are powered by the TALOS software interface and share common autonomy behaviors including transit autonomy, pattern autonomy, collaborative autonomy, collision avoidance, and remote command and control.
