Greek Defense Tech Startup Delian Alliance Industries Raises $14 Million Series A Financing

Delian Alliance Industries, a Greek Defence Tech Startup building autonomous systems for defence, led by Dimitrios Kottas(Founder and CEO), Ioannis Souriadakis(Co-Founder and Lead Hardware Engineer), and Matthew Wright(VP of Operations), Delian has raised a $14m Series A co-led by Air Street Capital and Marathon Venture Capital, with participation from 201 Ventures, HCVC, Entropy Industrial Capital and Nebular.

Delian enables autonomous threat detection and response by connecting any sensor to any effector across land, air, and sea. This integrated system forms a defensive "dome" to protect democratic allies. With a NATO-wide deployment already in progress, the new funding will accelerate efforts to meet rising global demand.

Delian combines advanced AI with commercial hardware from allied nations—an approach shaped by recent lessons from Ukraine and the Middle East. Defending against asymmetric threats and saturation attacks requires a shift from legacy, expensive weapons systems toward scalable, modern solutions designed for today’s battlefield realities.

Delian’s suite enables fast deployment of sovereign defense capabilities across two areas: Sense and Strike. Sense includes LAST towers for 24/7 surveillance, JERICHO for real-time targeting and field comms, and StrikeWeb for autonomous mission control. Strike features OSIRIS for GPS-free UAV navigation, Interceptigon-A and -N for air and sea threat neutralization, and M4K15 for electronic counter-UAV warfare.
