StirlingX, the data intelligence company building a sovereign intelligence and autonomy platform, has raised an oversubscribed £4 million second close of its Series A. That brings the 2026 round to £19 million. The new funding comes mainly from existing investors GALLOS Technologies and Ventura Capital, alongside individual investors.
StirlingX helps customers capture, secure, fuse, analyse and act on data from complex and contested environments. Its products are MAYNE, a data analytics product, and LEWES, a connected autonomy product. StirlingX runs one sovereign technology base across two markets: the capability that surveys, maps and monitors critical infrastructure also gives defence customers sovereign situational awareness, fusing data from drones, sensors and autonomous systems so commanders can act on it at speed.
StirlingX has activated its dual-use strategy, with 35 customers now operating across critical national infrastructure and defence, and has won its first multi-million dollar international contract. Each deployment in one market strengthens what StirlingX delivers in the other.
StirlingX has also appointed Magnus Grimeland, Founder and CEO of Antler, to its Board as Board Director, Global Scale & Capital. The capital will fund continued development of MAYNE and LEWES, alongside StirlingX's growth across defence and critical national infrastructure.
Our existing investors have seen how we work up close and chose to put more in, and we're grateful for that. Magnus joins us as we move from proving dual-use to scaling it. We've shown that the same sovereign technology can serve a utilities company and a defence ministry, and that each makes the other stronger. Magnus has built and backed companies across dozens of markets. He knows what it takes to turn early traction into global scale, and his experience will help us bring MAYNE and LEWES to allied governments and infrastructure operators who need to own and control their data.
Europe and its allies need to own the technology that protects its infrastructure and its people, and StirlingX is building exactly that: a sovereign control layer that lets drones, sensors and autonomous systems work together under human command. What drew me in was the combination of a team that has operated at the sharp end and a platform already working with the UK Ministry of Defence and critical infrastructure operators. This round gives Dean and the team the capital to take that from proven to scaled, and I am proud to be part of it.
