MARNEXII
Mission-critical maritime AI for sea and subsea operations, surveillance, & drone control.
A sensing, predictive decision-making, and control layer.
90% of global food, goods, and medicine move by sea, and will always do so.
Yet most ports operate on lagging, incomplete, or manually "written on scratch-pads" data.
Operators and regulators are alerted, make decisions, or threat assessments, hours or even days too late.
They're managing the world's most complex, critical, and delicate logistics infrastructure,... blindfolded.
Turns out that the Oceans Run on Blind Spots
Complete maritime observability is deterrence.
A multimodal AI built to see what up until now is invisible.
Sensor Suite Across All Products
Dark Vessel Detection
Detect non-AIS and invisible-to-radar small vessels from miles away. Accurately determine threat score.
Critical Infrastructure and Subsea Protection
Safeguard subsea cables and offshore farms from sabotage, trawling, and anchor dragging. Control, deploy, and send interdiction cues to port assets.
Defense
Maritime surveillance to protect strategic maritime zones from emerging risks and intrusions.
Port and Vessel Efficiency
Port control, demurrage curtailing, harbor docking, cargo loading, unloading, scheduling, and terminal operations made optimal.
Illegal At-Sea Rendezvous
Identify calls at sanctioned ports and illegal fuel transfers in black, grey, and high-risk areas.
Fisheries Protection
Accurately determine nature of attack (swap, spoof, multi positions output) initiated by vessels engaged in illegal fishing.
AI is Only as Good as the Data It Sees
AI cannot predict what it cannot perceive.
Maritime systems lack continuous, high-fidelity ground truth.
Marnexii is rebuilding that foundation - from the edge up.
A Living Digital Twin of Ports, Ships, Sea, and Subsea
Marnexii turns real-world sensor signals into a unified maritime AI.
It serves as a sensing, predictive decision-making, and control layer.
From dock operations to fleet movements and global surveillance. One real-time view of the global maritime waterways and underneath.
Maritime's Anduril Moment
Global trade strains, emissions rules, and AI-native infrastructure are converging.
Hardware costs are down, edge compute is up.
Ports are becoming networks, not facilities.
The next decade of shipping will be defined by who controls the data layer.
Data is an evergreen part of the AI process. Big model makers are mostly set (OpenAI, Anthropic, xAI, etc), but there will always be a need for new data to train and ground AI models on.
Product Demo
Pilots and Partnerships

The System That Sees Everything
Live edge receivers. Real data. Real-time dashboards.
Operational prototypes already in use.
Geospatial awareness and capability to deploy cameras and drones allow detection of non-radio and non-vessel objects in the waterways and under them.
Station Dashboard
Real-time monitoring and analytics
Vessel Map Viewer
Live positioning and route tracking
Metrics System
Performance and efficiency tracking
A Trillion-Dollar System, Slowed by Billion-Dollar Inefficiencies
Across global trade, inefficiencies exceed $100B annually - before emissions or throughput losses.
Marnexii targets the invisible layer beneath that: the data and decision infrastructure determining how ships move and ports breathe.
By fusing real-time signals into predictive control, we unlock value across every maritime operation, from port logistics to subsea infrastructure and security.
From Signals to Systems
Signals
Continuous edge data from our receivers and integrations. Licensed as a data feed or subscription API.
Predictive Modules
Real-time analytics and anomaly detection designed to plug into * Integration Partners, ERPs, port systems, and assets under port or security operator control.
AI Control Layer
Intelligence across fleet, port, sea, and subsea operations, powering surveillance, scheduling, routing, automation, and interdiction cues for assets.
Each layer compounds. The more signals we own, the smarter every connected system becomes.
Domain Roots. Technical Precision.
