Defence investor GALLOS has secured £35 million in new funding, highlighting a significant surge in investment for security and defence technology startups. The firm distinguishes itself by operating as a company builder rather than a traditional venture capital entity, focusing on nurturing mission-driven companies from Series Seed to Series B stages.
GALLOS concentrates its investments on breakthrough technologies across key security and resilience sectors, including Cyber Security, AI/Data Analytics, Defence Technologies, Resilience Solutions, and Autonomous Systems & Sensors. The company leverages an extensive network of over 100 CISOs and risk experts from Global 2000 companies, alongside senior security and national security leaders, to provide strategic insights, industry access, and growth opportunities to its portfolio companies.
Further underscoring the robust investor appetite for sovereign UK security technology, StirlingX, a company incubated by GALLOS, recently raised £15 million in a Series A funding round. StirlingX is developing a sovereign intelligence and autonomy platform for capturing, securing, and acting on data, with applications in defence, including counter-drone functions, and commercial uses such as surveying critical national infrastructure. The company's acquisition of drone-survey firm Hexcam in February 2025 and the appointment of former GCHQ Director Sir Jeremy Fleming as chairman in October 2025 further bolster its position in the market.
