Oxford-based StirlingX has raised a $20 million Series A round, the company announced on 2 July 2026, with backing from Ventura Capital and RCM Private Markets Master Fund managed by Rokos Capital Management US (LP).

The British data intelligence company develops drone operations and analytics technology that combines automated drone platforms, resilient communications and AI-driven software to turn aerial and sensor data into actionable insights. Its products are used in critical national infrastructure and defence settings, including surveying and monitoring infrastructure as well as detecting and countering hostile drones.

StirlingX said the new funding will be used to accelerate growth and product development as it expands support for customers operating in complex and difficult environments. The company was founded and incubated within GALLOS Technologies.

The raise comes shortly after StirlingX's seed round and follows what the company described as strong commercial traction, underscoring investor interest in sovereign, security-focused data and autonomy platforms.
