- Quartermaster raised a $140M Series B, with $100M in equity, to scale its SmartMast hardware for relaying real-time maritime data from ships.
- Quartermaster closed a $43M Series A earlier in May before quickly following up with the larger Series B, underscoring rapid investor momentum for the Arlington, Virginia-based startup.
Why it matters: Quartermaster went from a $43M Series A to a $140M Series B within months, a fundraising pace that signals defense-tech investors are racing to back startups building real-time sensor and data infrastructure for maritime operations.
