Quartermaster AI Inc. builds a distributed maritime sensor network that uses vessel-mounted sensor arrays with HD video, geolocation, and edge compute transponders to create a real-time picture of global ocean activity. Its AI models analyze video and sensor data to detect suspicious at-sea activities and threats, delivering visuals and insights through a hardened satellite link. The system turns civilian and commercial ships into persistent sensing nodes that collectively provide continuous maritime domain awareness for coast guards, navies, insurers, and researchers. The goal is to improve safety, security, and environmental oversight by providing timely, verifiable intelligence that supports rapid, coordinated responses.
