GALLOS Technologies has secured $50 million (£35 million), giving the London-based investor new capacity as capital flows into security and defence technology. Jointly led by Ventura Capital and Aberdeen Investments, the round reflects confidence in businesses tackling security challenges. For GALLOS, the funding expands its capacity to build and back companies positioned at the intersection of national security, advanced technology, and commercial demand.
Key Takeaways
GALLOS Technologies has secured £35 million in a funding round led by Ventura Capital and Aberdeen Investments, underscoring a significant surge in European investment within the security and defence technology sector.
- The £35 million raised by GALLOS Technologies will be used to expand its capacity to support start-ups at the intersection of national security, advanced technology, and commercial demand, combining capital with security expertise and strategic support.
- This funding round reflects a broader trend of increasing venture capital investment in European defence, security, and resilience start-ups, which saw an 8.7 billion dollar increase in 2025.
- The success of GALLOS’s model, which offers specialist guidance alongside capital, is crucial for the growth of European defence start-ups, particularly those developing dual-use technologies, and could accelerate the innovation pipeline from concept to market.
GALLOS puts £35 million behind security innovation
Its leadership combines national security expertise with defence technology experience. Josh Burch brings a background in national security, while Dean Jones leads StirlingX. Former GCHQ director Sir Jeremy Fleming is among the company’s advisers.
The funding will support more start-ups and GALLOS’s platform. Its portfolio includes StirlingX, focused on drone operations and data intelligence, and AI Score, an enterprise platform for AI compliance, governance and optimisation.
Those investments illustrate GALLOS’s company-building approach. Rather than supplying finance alone, it combines capital, security expertise and strategic support, strengthening its position within defence venture capital as founders move towards government and commercial markets.
GALLOS deal reflects Europe’s defence funding surge
This funding arrives amid a sharp expansion in European security investment. According to Dealroom and the NATO innovation fund, venture backing for Europe’s defence, security, and resilience start-ups reached $8.7 billion in 2025, a 55% increase from the previous year.
That momentum has continued. Munich-based Helsing has attracted substantial new backing, reinforcing investor appetite for advanced defence technology. For European defence startups, that interest highlights demand for AI, autonomous systems and technologies with clear security applications.
It operates earlier in the funding cycle, helping companies develop technology and routes to adoption. That gives it a role within European defence tech, where founders need specialist guidance alongside capital. The model also suits dual-use technology defence, where innovations may serve security and civilian needs. As defence venture capital expands, that mix of funding and operational expertise could become valuable.
Why the GALLOS raise matters next
The next test for European defence startups is whether rising investment can translate into lasting capability. Growth will depend on credible technology, customer access and clear routes into government and commercial markets.
GALLOS’s £35 million raise therefore matters beyond one deal. By helping promising technologies move faster from concept to market, the firm can strengthen Britain’s innovation pipeline. If specialist expertise keeps pace with capital, Europe could build more scalable defence-tech companies, attract further investment and accelerate security-technology growth.
