British data intelligence startup StirlingX Ltd. has raised $20 million in an early-stage round to accelerate product development and push into new markets.

StirlingX describes itself as a data intelligence company built inside a drone maker. Its platform is designed to capture, secure, fuse, analyze and act on data pulled from complex and contested settings.

The company designs and manufactures its drones, autonomous systems and analytics software in Britain, with sites in Cambridge and Oxford. Customers span critical national infrastructure and defense and current work runs from surveying and monitoring infrastructure to detecting and countering hostile drones. Named clients include utility National Grid plc and engineering group Murphy.

StirlingX was built and incubated inside GALLOS Technologies Ltd., a venture studio that creates security companies staffed by veterans of national intelligence and defense work. It spun out as a standalone business today and named Sir Jeremy Fleming chairman. Fleming ran the U.K.’s Government Communications Headquarters, the signals intelligence agency known as GCHQ, and his appointment hands the young company boardroom experience from one of the Five Eyes’ core agencies.

Dean Jones, founder and Chief Executive of StirlingX, said that the Series A round positions the company to compete for larger government contracts. “We are building a category-defining sovereign data intelligence company,” Jones said. “This Series A will drive our business forward as we scale with new and existing partners across critical national infrastructure and defense ministries and agencies.”

Fleming said the ability to securely capture, fuse and act on data has become a strategic advantage in an increasingly contested world, and that the funding would accelerate a “uniquely British capability” with national and export potential.

The Series A follows what StirlingX describes as significant commercial traction since its seed raise, as government agencies and infrastructure operators look for sovereign alternatives to foreign-owned data platforms.

Ventura Capital led the round alongside RCM Private Markets Master Fund, managed by Rokos Capital Management US LP. Mo El Husseiny, managing partner at Ventura Capital, called StirlingX a combination of establishment trust and technical execution and “the trusted solution for Five Eyes and beyond.” Jonathan Ross, who leads Rokos Capital Management’s private markets team and is an existing shareholder, said the firm was growing its stake as the company enters its next phase.

StirlingX will use the capital to grow its security software engineering team and fund product work for military and civilian customers operating in high-risk environments.

The starup previously closed an $11 million extended seed round in November 2025 while still incubated within GALLOS Technologies, taking its total funding to $31 million with the Series A included.
