StirlingX has raised £15 million in a Series A round led by Ventura Capital and RCM Private Markets Master Fund managed by Rokos Capital Management US (LP), just months after its seed round, in response to significant commercial traction. Building a sovereign intelligence and autonomy platform, StirlingX helps customers capture, secure, fuse, analyse and act on data from complex and contested environments. The capital will accelerate company growth and product development to support customers delivering complex missions in the hardest of operating environments.
StirlingX addresses one of the most consequential challenges in modern national security: the secure capture of, and ability to act upon, high-value data at speed and scale in complex, sensitive and contested environments. Operating across critical national infrastructure and defence environments, its current use cases range from surveying, mapping and monitoring critical infrastructure to detecting and countering hostile drones.
StirlingX is chaired by the former Director of GCHQ, Sir Jeremy Fleming. Founded and incubated within GALLOS Technologies, a venture studio and investor that builds and invests in cutting-edge security technology companies, StirlingX draws on decades' worth of nation-state-level security, intelligence and defence experience.
We are building a category-defining sovereign data intelligence company. This Series A will drive our business forward as we scale with new and existing partners across critical national infrastructure and defence ministries and agencies.
In an increasingly contested world, the ability to securely capture, fuse and act upon data is becoming a critical strategic advantage. This investment in StirlingX will accelerate the development of a uniquely British capability with significant national and international potential.
StirlingX represents a unique combination of establishment trust, technical expertise and execution excellence. The utilisation of powerful data intelligence has become a must for Government and corporates, and increasingly so within a sovereign-secure framework. StirlingX is the trusted solution for Five Eyes and beyond. We are delighted to lead this Series A and we are looking forward to supporting the business as it scales against its huge opportunity set.
As an existing shareholder we have seen firsthand the quality of the team and scale of their ambition. We are proud to grow our investment in StirlingX as it moves into this next phase.
