Surtr Defense Systems
Surtr Defense Systems builds ParallaxOS, an open counter-UAS operating system for sensor fusion, C2 and human-authorized effector tasking. The San Francisco company raised a $4.8M seed in July 2026 and has tested acoustic and visual FPV-drone tracking with military operators in Ukraine.
Market context
Robotic defence systems only become useful at scale when sensors, unmanned systems, operators, and decision tools can work together. Surtr matters as a software layer focused on interoperability rather than a single platform.

Partner-neutral defence C2 and data fusion
Surtr is building a defence software layer for integrating Western hardware, live operations, and AI decision support.
- Target environment: Defence operations involving sensors, unmanned systems, operators, and multi-vendor hardware networks.
- Deployment model: Software platform sold into defence and partner ecosystems as command-and-control and data-fusion infrastructure.
- Customer context: Military units, defence integrators, and hardware vendors that need trusted interoperability across operational systems.
- Workflow context: Connects platform data, operator workflows, and AI-assisted decisions in environments where proprietary hardware silos slow integration.
- Commercial maturity: Early defence-software company developing command-and-control, data-fusion, and AI decision infrastructure for multi-vendor operational systems.
- Market position: Infrastructure provider for defence autonomy and robotic-system interoperability.
- Adoption constraints: Adoption depends on procurement access, partner trust, cyber/security assurance, and integration with operational hardware.
- Adjacent context: Adjacent context includes defence autonomy software, command-and-control platforms, sensor-fusion systems, and mission-software companies.
- Source confidence: high
