GoKawiilQuartermaster closes $140M Series B for maritime sensor network
Arlington-based Quartermaster raised a $140 million Series B just months after closing a $43 million Series A in May, according to CEO Neil Sobin. Roughly $100 million came from equity investors led by Insight Partners, with new backer Overmatch Ventures and existing investor First Round Capital, while the remaining $40 million came as debt financing from Stifel. The startup builds weather-hardened camera and radio hardware called SmartMast that mounts on ship masts to deliver real-time maritime data beyond basic AIS location pings.
