Quartermaster builds SmartMast, a network of vessel-mounted sensors and AI that gives maritime, commercial, and government operators real-time visibility into ocean activity.
Quartermaster is addressing sparse, delayed, fragmented, and spoofable maritime data by turning existing commercial fleets into a persistent sensing network; the latest report says more than 650 vessels in 25 countries use SmartMast and that more than 800 units have shipped to customers. Its current $140 million Series B, including about $100 million of equity led by Insight Partners and Overmatch Ventures and a $40 million Stifel debt facility, follows the $43 million Series A and funds a bet that distributed vessel-based intelligence can become core infrastructure for shipping, government, and insurance.
