## About

Quartermaster AI Inc., based in the US, specializes in maritime domain awareness by utilizing advanced AI and HD video technology to enhance safety and operational efficiency across global maritime operations. Quartermaster AI Inc. was founded in 2023 in Arlington, US, focusing on maritime domain awareness solutions. The company was founded by Neil Sobin (CEO). In September 2026, Quartermaster AI Inc. raised USD 140 million in series B and venture debt funding co-led by Insight Partners and Overmatch, with participation from First Round Capital, Quiet Capital, Steel Atlas, TMV, BoxGroup, Multiple Management Company, and Stifel. Quartermaster's core offering is a comprehensive maritime domain awareness system that transforms civilian and commercial fleets into a robust, distributed maritime sensing network. This system integrates vessel-mounted HD video, geolocation, and advanced artificial intelligence to provide real-time visibility of maritime activities. The solution enables users to monitor vessel movements, identify unusual activities, and respond proactively to incidents, enhancing safety and operational efficiency. The technology is particularly valuable for maritime security agencies, commercial shipping companies, and other stakeholders involved in maritime operations across various global markets, including North America, Europe, and parts of Asia-Pacific. By deploying over 600 sensors across more than 25 countries, Quartermaster facilitates access to HD video feeds and location data, thereby extending the operational reach of its clients beyond their immediate fleets and routes. Quartermaster generates revenue primarily through a subscription-based model, whereby clients pay for access to its maritime awareness platform and associated services. This structure allows organizations to maintain real-time monitoring capabilities while leveraging the extensive data provided by the company’s SmartMast™ fleet. Transactions typically involve long-term partnerships with commercial shipping lines, maritime security firms, and governmental agencies that require comprehensive surveillance and tracking solutions. While specific pricing details for the services are proprietary, clients engage with Quartermaster’s platform through tiered subscription plans, which may include various levels of access to video feeds, geolocation data, and AI-driven alerts. The company’s business model emphasizes reliability and real-time data, positioning it as a critical partner for organizations aiming to enhance maritime safety and operational effectiveness.

The company will use the September 2026 funding to expand SmartMast production capacity and increase adoption across international shipping fleets.
