Quartermaster is building a maritime hive mind

Quartermaster raised a $43 million Series A led by First Round Capital and Quiet Capital.

The company will use the funding to scale SmartMast, a mast-mounted sensing and analytics network.

SmartMast is already installed on more than 600 ships and collects real-time ocean data.

The platform can support ship identification, rescue operations, and broader maritime intelligence.

It aims to reduce reliance on AIS, which can be spoofed or evaded.
