What Greensea Systems, Inc. does
Greensea Systems, Inc., doing business as Greensea IQ, is a privately held maritime robotics and software company founded in 2006 and headquartered in Richmond, Vermont. It develops intelligent robot software and unmanned systems for defense, commercial maritime, and scientific research customers, organized around two product lines. Bayonet is a seabed and surfzone autonomous robotics platform offered in defense and maritime variants (including the Bayonet 350 model) and complemented by software modules for combat diver navigation and multi-platform command and control, plus an operator training simulator launched in March 2026. EverClean is a recurring underwater hull management service delivered via six U.S. coastal offices (Richmond VT, Plymouth MA, San Diego CA, Houston TX, Rockledge FL, Miami FL) that provides hull cleaning, inspection, and readiness support for both defense and commercial fleets, with a Post-Mission Analysis Toolset introduced in March 2026 to convert mission data into customer-facing analytics.
The company monetizes through a mix of robotics hardware sales (Bayonet), recurring service revenue (EverClean hull maintenance contracts), and software/subscription products (command and control, combat diver navigation, post-mission analytics). Its go-to-market is enterprise-direct, with dedicated Defense and Maritime product tracks, industry-event presence, and a content-driven website funnel. Customer mix is concentrated in naval and defense buyers plus commercial fleet operators, with academic and oceanographic institutions served through a Science Partnerships program.
The company does not disclose funding rounds, investors, or absolute revenue figures, though it reported 26% year-over-year growth to a record 2025 revenue base in February 2026. It targets a structurally growing category — autonomous offshore platform cleaning robots projected to reach $2.47 billion by 2030 at a 12.6% CAGR. With 11-50 employees and leadership that includes Chelsea Allen as Vice President of Operations, Greensea IQ positions itself as a specialist in maritime autonomy rather than a broad-based undersea vehicle manufacturer, relying on 20 years of accumulated software and domain IP as its principal defensible asset.

Greensea Systems, Inc. product offering
Product offeringCore offering
Greensea IQ designs intelligent robot software and builds high-impact autonomous robotics for maritime applications. It sells the Bayonet autonomous seabed and surfzone robotics platform (with defense and maritime survey variants, the Bayonet 350 model, a training simulator, combat diver navigation, and command-and-control software) and operates the EverClean underwater hull management service for defense and commercial fleets. Offerings target defense organizations, commercial maritime fleet operators, and academic/research institutions across multiple U.S. coastal locations.
Product overview
Greensea IQ operates a platform-plus-products architecture built around two primary product lines: Bayonet (autonomous seabed and surfzone robotics) and EverClean (underwater hull management). The Bayonet platform includes defense and maritime variants, specialized models like Bayonet 350, a training simulator, and associated software modules for combat diver navigation and command and control. EverClean provides hull cleaning and maintenance services for both commercial maritime and defense fleet applications. Both platforms leverage the company's core intelligent robot software technology developed since 2006, with applications spanning defense, transportation, energy, and science.
