What Greensea IQ does

Greensea IQ is a vertically integrated subsea robotics and autonomy company headquartered in Richmond, Vermont, formed in September 2023 through the merger of Greensea Systems, Bayonet Ocean Vehicles, and Armach Robotics. The company develops and deploys autonomous maritime robots for two primary end markets: U.S. and allied defense forces (mine countermeasures, explosive ordnance disposal, unexploded ordnance detection, and seabed/surf-zone operations) and commercial shipping operators (proactive hull biofouling management and inspection). The technology stack is anchored by OPENSEA, an open-architecture robotics software platform developed continuously since 2006 that provides robot control, navigation, sensor fusion, autonomy, perception, and modular payload integration across all Greensea IQ products. Hardware lines include the Bayonet 150/250/350 family of Autonomous Underwater Ground Vehicles (AUGVs) for surf-zone and nearshore defense operations and the EverClean Hull Service Robot and EverClean Inspection Robot for commercial maritime hull maintenance. Supporting products include the Bayonet Underwater Controller for combat-diver submerged command-and-control, IQNS edge navigation, OPENSEA Edge autonomous processing, EOD Edge and EOD Workspace defense software, and Safe C2 over-the-horizon communications.

The company generates revenue through five streams: (1) Bayonet AUGV hardware sales to U.S. and allied defense forces under multi-year IDIQ contracts and firm-fixed-price task orders (disclosed contracts totaling $19M+ in 2024–2025 across USMC LEON, Navy MESR, NAVSEA, and DIU programs); (2) EverClean recurring Robotics-as-a-Service subscriptions for proactive hull cleaning at ports across the U.S. East Coast, Gulf Coast, Bahamas, and Caribbean; (3) OPENSEA and defense software licensing (EOD Edge, EOD Workspace, Bayonet Workspace); (4) defense software development contracts including SBIR-funded R&D; and (5) direct EverClean Inspection Robot sales. Go-to-market combines direct enterprise sales for defense, owned field operations for EverClean at key U.S. ports, regional service-provider partnerships (Baker Marine Solutions in Louisiana, Executive Marine Management in the Bahamas), and seven authorized international representative partners covering Australia/NZ, Israel, France/Belgium, Japan, Italy, SE Asia, the UK, and Spain.

The company reports 51–100 employees across seven offices (Richmond VT HQ; Plymouth MA manufacturing; San Diego CA engineering/near Navy Base Point Loma; Rockledge FL; Hialeah FL; League City TX near Houston; Monroe Township NJ near Port of NY/NJ) and was recognized as a DIU A2RV program finalist (2025) and shortlisted for the Ocean Opportunity Lab Biofouling Innovation Challenge (2022). FY2025 revenue grew 26% year-over-year and doubled over 2024–2025, with cumulative EverClean performance exceeding 350 service deployments and 308,000+ square meters of hull surface cleaned since commercial launch.

Direct peers

• VideoRay (AeroVironment): VideoRay manufactures the Mission Specialist Defender ROV, which Greensea IQ equips with EOD Edge software, IQNS navigation, and Bayonet Underwater Controller under a strategic multi-million-dollar partnership. Direct competitor in small/mid-size defense ROV market and active co-development partner.
• Sonardyne: Sonardyne provides underwater acoustic positioning, navigation, and communication systems for subsea robotics and defense. Both companies supply navigation and acoustic comms hardware/software (e.g., IQNS, Safe C2) to defense and commercial operators of underwater vehicles.
• Hullbot: Hullbot develops autonomous underwater robotic hull cleaning systems for the maritime industry. Direct competitor in the autonomous hull grooming space where Greensea IQ's EverClean service competes for shipowner adoption and port operators.

Broad incumbents

• Ocean Infinity: Ocean Infinity operates a global fleet of autonomous marine robots for seabed mapping, survey, and search. Both companies pursue autonomous maritime survey at scale using underwater robotic platforms, though Ocean Infinity is much larger and focuses on deep-water vessel-based operations.
• Kongsberg Maritime: Kongsberg Maritime is a leading supplier of naval sonars, autonomous underwater vehicles (Hugin), and underwater positioning systems. It is a broad incumbent across all of Greensea IQ's defense and commercial maritime autonomy product lines, with much greater scale and incumbency in naval procurement.
• Saab (Sea Wasp / Sabertooth): Saab provides the Sea Wasp unmanned surface vehicle and Sabertooth AUV for MCM/EOD operations. Saab directly competes in the defense MCM/EOD autonomous underwater market that Greensea IQ addresses through the Bayonet AUGV line.
• Teledyne Marine: Teledyne Marine is a broad supplier of underwater imaging, instruments, vehicles, and acoustic communication systems. It supplies components and integrated platforms overlapping with Greensea IQ's sensor, navigation, and imaging product stack, with significantly greater scale.

Emerging players

• Saildrone: Saildrone builds wind- and solar-powered autonomous surface vehicles for defense, maritime security, and ocean data. While primarily a USV company, it competes in the broader autonomous maritime intelligence market with significant defense funding and a recent multi-billion-dollar valuation context.
• Sea Machines Robotics: Sea Machines develops autonomy software for marine vessels (command and control, computer vision, path planning). Greensea IQ's SVP of Technology previously served as Director of Engineering at Sea Machines, indicating direct technical overlap in marine autonomy stacks.
• Bedrock Ocean: Bedrock Ocean provides autonomous underwater survey and inspection services using AUV technology. It competes in the subsea autonomous survey market where Greensea IQ's Bayonet AUGVs and OPENSEA-powered solutions serve defense and commercial customers.
