Groke Technologies

What Groke Technologies does

Groke Technologies is a Finnish maritime technology company founded in October 2019 in Turku by four former members of Rolls-Royce's ship intelligence team. The company develops situational awareness systems for commercial vessels, combining sensor fusion (4K visual camera with 225-degree field of view, 180-degree thermal camera, AIS, radar/ARPA, GNSS, IMU, and sea charts) with proprietary machine vision models trained on a multi-year in-house vessel image database. Its flagship product, Groke Pro, acts as a digital watchkeeper on the vessel bridge, detecting and classifying vessels — including non-AIS targets — in day, low-light, and night conditions, and providing real-time risk analysis with end-to-end latency under 500 milliseconds. A complementary onshore product, Groke Fleet, extends the platform to fleet managers with route playback, 4K event imagery, and automated reporting.

The company generates revenue primarily through one-time sales of the integrated Groke Pro hardware-plus-software system (installed as a 4–6 hour retrofit) to ship owners and operators, with a growing subscription component via Groke Fleet and a planned Groke Cloud offering. Pricing is not publicly disclosed; the company runs an enterprise field-sales motion built on demo-based engagement, pilot installations, and customer references, with the commercial team drawn heavily from maritime industry veterans (Wärtsilä, Sperry Marine/Northrop Grumman, Eniram, DFDS). The customer base is concentrated among Japanese enterprise shipping companies that double as strategic investors — Mitsubishi Corporation, Oldendorff Carriers, Uyeno Transtech, Tsurumi Sunmarine, Asahi Tanker, Tokyo Kisen, SMFL, K-Line, U-Ming Marine, and VG Shipping — with initial market focus on Japanese coastal shipping and international expansion underway. As of May 2026, NACOS Marine acquired Groke Technologies, which now operates as NACOS Marine Finland Oy with the technology rebranded as NACOS Vision Assist for global rollout.

Core offering

Groke Technologies develops and sells Groke Pro, a maritime situational awareness system for vessel bridges that uses sensor fusion of 4K day cameras, thermal cameras, AIS, radar, GNSS, IMU and sea charts to provide machine-vision object detection and real-time collision risk analysis with sub-500ms latency. It also offers Groke Fleet, a shore-side fleet management software that aggregates vessel data into 4K event imagery, route playback and automated reporting for fleet managers. The company sells to commercial ship owners and operators (tankers, dry bulk, ferries, tugboats) through direct enterprise sales with multi-year contracts and a regional office in Japan.

Product overview

Groke Technologies offers a portfolio of maritime situational awareness solutions centered on sensor fusion, machine vision, and machine learning technologies. The core offering consists of Groke Pro, a digital watchkeeper system for vessel bridges, and Groke Fleet, a fleet management platform for shore-side operations. These products work together: Groke Pro provides onboard situational awareness with real-time risk analysis, while Groke Fleet aggregates this data for fleet-wide monitoring. Groke Cloud is a planned add-on for office-side data utilization. The company's technology stack is built on sensor fusion combining cameras, radar, AIS, GNSS, and IMU sensors, with machine vision powering object detection and classification capabilities.

Scale indicators4 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Wärtsilä: Finnish marine technology major with smart-ship, navigation, and autonomous-vessel programs. Groke's CCO Jonas Bergring previously held senior roles at Wärtsilä, illustrating direct talent overlap and competitive adjacency in marine digitalization.
• Furuno: Established Japanese marine electronics manufacturer with dominant share in marine radar, ECDIS, sonar, and bridge systems. Groke's partner investors (Japanese shipping operators) are Furuno customers, and Furuno represents the most likely incumbent to bundle camera-based perception into integrated bridge offerings.
• Sperry Marine (Northrop Grumman): Northrop Grumman's marine navigation business offering radar, ECDIS, and integrated bridge systems globally. Groke's sales advisor Jan Thordan Hansen spent 30+ years here, underscoring how Groke competes with and sells into this incumbent's customer base.
• Kongsberg Maritime: Norwegian provider of integrated bridge systems, autonomous shipping platforms, and marine automation. NACOS Marine (which acquired Groke) operates in the Kongsberg ecosystem, making Kongsberg a natural adjacent incumbent and distribution pathway.
• Raytheon Anschütz: German manufacturer of marine navigation and bridge systems including radar, ECDIS, and integrated bridge consoles. Competes with Groke for shipowner mindshare on bridge modernization and watchkeeping upgrades.

Others

• Marlink: Global provider of maritime connectivity, digital solutions, and managed services to commercial fleets. Comparable target customer (shipowners) and complementary as a fleet-management layer where Groke Fleet could integrate or compete.
• Japan Radio Co. (JRC): Japanese marine electronics manufacturer and partner of Groke in the K-Line autonomous-ship R&D initiative. Comparable in marine radar and navigation products, and a partner/competitor depending on commercial outcome of the joint initiative.

Direct peers

• Sea Machines Robotics: Boston-based autonomous marine technology company providing computer-vision perception and autonomous command for commercial vessels. Comparable AI perception stack and autonomous-navigation positioning to Groke's roadmap.
• Avikus: HD Hyundai subsidiary commercializing autonomous navigation and situational awareness for ships, including the HiNAS control system. Directly comparable in maritime autonomy and vision-based navigation, with backing from a major shipbuilder.
• Orca AI: Israel-based maritime AI company offering computer-vision-based situational awareness and watchkeeping systems for commercial vessels. Direct overlap with Groke Pro in thermal/visual object detection, AIS fusion, and bridge augmentation.
