Quartermaster, an Arlington, Virginia-based maritime data analytics company, has raised $43 million in Series A funding.

The round was co-led by First Round Capital and Quiet Capital. TMV Logistics, Steel Atlas, BoxGroup, Operator Partners, Shorewind Capital, and David Adelman also participated.

What the company plans to do with the funding

Quartermaster said it will use the capital to expand its onboard sensor network into new regions and vessel categories. It also plans to strengthen its core analytics platform and add to its engineering, product, and go-to-market teams.

What Quartermaster builds

Led by Neil Sobin, Quartermaster develops SmartMast, a hardware and software platform for commercial vessels. The system turns ships into data collection points by capturing environmental data, vessel activity, video feeds, and radio anomalies.

The company combines that data into a structured maritime awareness network. Its customers include insurers, logistics companies, and maritime agencies.

Current network scale

Quartermaster said its active tracking network now covers more than 10 million square miles of ocean. The network includes more than 600 active commercial vessels across 25 countries and four continents.
