Quartermaster, a provider of SmartMast systems for ships, secured $140M in Series B funding, including $100M in equity. The round follows a $43M Series A completed in May.

Quartermaster's SmartMast technology enables real-time data relay from vessels, addressing what the company describes as the largest information gap in global shipping operations. The Series B funding brings total capital raised to $183M. The equity component of the latest round reflects strong investor confidence in the maritime data market, which has historically lacked standardized monitoring infrastructure. SmartMast systems provide ships with continuous environmental and operational awareness, improving safety and efficiency across maritime logistics. The technology targets a sector that relies heavily on fragmented communication systems and delayed data reporting. The rapid funding cycles—Series A to Series B in roughly six months—indicate accelerating market demand and validation of Quartermaster's approach to digitizing maritime operations. The company plans to scale its deployment across commercial and industrial shipping fleets.
