GateHouse Maritime

What GateHouse Maritime does

GateHouse Maritime A/S, founded in 1992 and headquartered in Nørresundby, Denmark, with a US subsidiary (GateHouse USA Corp.) in Tampa, Florida, develops maritime domain awareness (MDA) software that integrates terrestrial and satellite-based AIS, radar, LRIT, and other geospatial data sources into a unified web-based platform called the Maritime Domain Monitor (MDM). The platform processes approximately 150 million daily vessel movements and is complemented by modular add-on products including Event Alerting, Advanced Analytics (machine learning-driven ETA and next-port prediction), AIS Network Monitoring, Aids to Navigation, Dark Ship Detection, Extended Vessel Information, Replay & Reporting, and Data Mediation. The company also operates OceanIO, a sub-brand providing container and vessel tracking for the logistics and freight market, aggregating over 350 billion data points.

GateHouse Maritime sells primarily through enterprise field sales via dedicated Commercial Directors covering the US and EMEA+ROW, supported by an API-first distribution model that enables integration into existing customer systems. Revenue derives from platform subscriptions with modular add-ons, multi-year monitoring contracts (e.g., a 5-year GAZ-SYSTEM contract for Baltic Sea pipeline surveillance), data mediation/managed services, and professional services for implementation and training. Pricing is quote-based with no publicly disclosed tiers. The company holds ISO 9001:2015 certification and is aligned with IALA A-124 AIS Service Management standards.

The customer base spans maritime authorities and coast guards (Irish Coast Guard, Danish Maritime Authority, DanPilot, Marine Exchange of Alaska), defense and intelligence agencies (US Army Corps of Engineers), subsea cable and pipeline operators (Tusass/Tele Greenland, GAZ-SYSTEM), offshore energy operators, environmental agencies (NOAA), and logistics customers via OceanIO. In 2026, the company transitioned to operating as an independent maritime data technology company under new CEO Thomas Scott Jensen, and in late 2025 expanded into port airspace security with Drone Detection for Ports. The company reports 51-100 employees and an 80%+ customer retention rate over 6+ years.

Core offering

Gatehouse Maritime develops and sells a web-based maritime domain awareness software platform called Maritime Domain Monitor (MDM) that combines AIS, radar, LRIT, and other geospatial data for real-time and historical vessel tracking. Around MDM, the company offers modular add-on products for event alerting, AIS network monitoring, aids-to-navigation management, advanced analytics, extended vessel information, dark ship detection, and data mediation, sold to maritime authorities, coast guards, defense organizations, subsea cable and pipeline operators, offshore energy operators, and logistics customers (via the OceanIO sub-brand).

Product overview

GateHouse Maritime delivers maritime domain awareness and critical infrastructure protection through a modular platform architecture. The core platform, Maritime Domain Monitor (MDM), is a web-based solution integrating real-time and historical data from AIS (terrestrial and satellite-based), radar, LRIT, and other geospatial sources into a unified interface. The MDM platform serves as the central hub, with modular add-on products that can be added based on operational needs: Replay and Reporting for historical analysis and incident reconstruction; Event Alerting for real-time geofencing and threat detection; AIS Network Monitoring for infrastructure management; Aids to Navigation for navigational aid control; Advanced Analytics for machine learning-powered predictions; Extended Vessel Information for comprehensive vessel data; Dark Ship Detection for identifying vessels operating without AIS; and Data Mediation for AIS data processing and distribution. A sub-brand, OceanIO, provides container tracking for logistics and supply chain visibility. The platform tracks and analyzes 150 million daily vessel movements, serving maritime authorities, coast guards, navies, subsea cable operators, and offshore asset owners worldwide.
