StirlingX

London-headquartered defence intelligence startup StirlingX has successfully raised $20 million (£15 million) in a Series A funding round co-led by Ventura Capital and RCM Private Markets Master Fund (managed by Rokos Capital Management US).

Summary of transaction details:

• Value: $20 million (£15 million) Series A (closed just eight months post-Seed capitalization).
• Sector: DeepTech & AI / DefenceTech / Critical Infrastructure Security.
• Advisor / Corporate Board Updates: Sir Jeremy Fleming, former Director of GCHQ and MI5 officer, serves as corporate Chairman. Special security venture builder GALLOS Technologies assisted as an early advisory partner.
• Key Entities: Target: StirlingX Limited; Lead Investors: Ventura Capital, RCM Private Markets Master Fund; Participating Investors: GALLOS Technologies; Key Founder: Dean Jones (CEO & Founder).
• Location: London, UK.

Note: Founded by special operations veteran Dean Jones alongside security specialists from UK military and intelligence units, StirlingX operates as a advanced data intelligence provider utilizing proprietary unmanned aerial hardware as its edge capture nodes. The platform addresses a critical gap within the "Five Eyes" intelligence network and Western critical infrastructure security: the ability to safely capture, end-to-end encrypt, fuse, and parse real-time sensor streams within highly contested or electronically jammed operational theaters. Its dual-use spectrum-resilient framework allows commercial operators like National Grid to automate complex pipeline surveys, mapping, and construction-phase oversight, while simultaneously serving defense agencies via autonomous counter-UAS (unmanned aerial systems) and hostile drone interception tracking. This oversubscribed $20m round—closing on the back of rapid commercial procurement traction following an initial $11 million seed stage—will fund core international hiring, support localized sovereign data storage expansion, and accelerate product pipelines across foreign ministries of defence.
