# Quartermaster

> Quartermaster is an Arlington, Virginia maritime intelligence company turning ordinary working ships into a distributed sensing network. Its weather-hardened SmartMast hardware - cameras, radios, satellite links and onboard AI - mounts to vessel masts and streams real-time HD video, geolocation and threat alerts back to a central analytics platform. The result is a live, continuously updated picture of global ocean activity that does not depend on the easily spoofed AIS transponders ships can simply switch off. Backed by a $43M Series A co-led by First Round Capital and Quiet Capital, Quartermaster already runs on more than 600 vessels across 25 countries.

- **Headquarters:** Arlington, Virginia, United States
- **Founders:** Neil Sobin (Founder & CEO)
- **Team size:** ~51 employees
- **Products:** SmartMast, Maritime Intelligence Platform, Data & Training Feeds
- **Notable:** Raised a $43M Series A co-led by First Round Capital and Quiet Capital (May 2026)., Deployed SmartMast on 600+ active vessels across 25 countries and four continents., Covered over 10 million square miles (25.9M sq km) of ocean.

## Products & services

- **SmartMast** — A weather-hardened sensor kit mounted on a ship's mast, combining cameras, radios, radar/signal receivers, satellite connectivity and onboard (edge) AI. It turns a vessel into an intelligent data-collection node, streaming HD video, geolocation and AI-driven alerts about nearby vessels and unusual activity.
- **Maritime Intelligence Platform** — A central analytics platform that fuses data from the SmartMast network into a live, distributed picture of global ocean activity. It identifies and geolocates vessels, detects ships running without AIS, and preserves timestamped, authenticated chain-of-evidence records.
- **Data & Training Feeds** — Real-world maritime imagery and signal data used by marine autonomy companies, scientific and robotics researchers, and government intelligence customers.
