Arlington, Virginia-based maritime technology startup Quartermaster has secured $43 million in Series A funding to accelerate deployment of its AI-powered ocean sensing and maritime intelligence platform. The round was co-led by First Round Capital and Quiet Capital, with participation from TMV Logistics, Steel Atlas, BoxGroup, Operator Partners, Shorewind Capital, and investor David Adelman. Founded by Neil Sobin, Quartermaster is building a distributed maritime sensing network through its “SmartMast” platform - a rugged onboard system combining cameras, radios, geolocation sensors, and edge AI computing installed on commercial and civilian vessels. The company describes the system as a “continuous distributed sensing network” capable of delivering real-time maritime intelligence across millions of square miles of ocean. Quartermaster aims to modernize maritime monitoring infrastructure beyond the traditional AIS (Automatic Identification System), which the company says is vulnerable to spoofing, manipulation, and operational blind spots. Its AI-powered sensing network is designed for applications including shipping intelligence, sanctions monitoring, maritime safety, autonomous navigation, defense operations, logistics visibility, and environmental monitoring. According to the company, SmartMast systems are already deployed across more than 600 vessels covering over 10 million square miles of ocean. Quartermaster also stated that its network has assisted in more than 20 maritime rescue operations to date. The fresh capital will support engineering expansion, product development, and global scaling of Quartermaster’s edge AI maritime infrastructure as governments, logistics firms, insurers, and defense operators increasingly seek real-time ocean intelligence systems.
