Delian Advances European-Led Autonomous Defense with $14M Series A Financing
ATHENS, Greece and LONDON, UK, July 29, 2025 — Delian Alliance Industries has raised a $14m Series A to accelerate the production of affordable, autonomous systems that defend against invasion and incursion at nation scale.
The round was co-led by Air Street Capital and Marathon Venture Capital, with participation from 201 Ventures, HCVC, Entropy Industrial Capital and Nebular.
Delian seamlessly connects any sensor to any effector, enabling the autonomous detection and defeat of incoming threats across land, air, and sea. This integrated approach creates a defensive ‘dome’ that protects democratic allies. With a NATO country-wide deployment already underway, the funding will accelerate the company’s efforts to meet growing international demand.
“Our adversaries are arming themselves with emerging technologies at a rapid industrial scale,” said Dimitrios Kottas, founder and CEO of Delian. “We’re in a race against time and should measure deployments in days, not decades. We’ve proven our systems in mission critical environments and will now ramp up production internationally”.
Delian’s approach is to combine advanced AI with commercial hardware from allied nations. This builds on the recent lessons from Ukraine and the Middle East. It is not militarily or economically viable to defend against asymmetric threats and saturation attacks by relying on an ageing and expensive stockpile of weapons built for a different era.
Delian’s product suite is built for rapid integration into Europe’s evolving defense priorities, enabling swift delivery of sovereign capabilities at scale. It is split into two areas: Sense and Strike.
Sense:
LAST Autonomous Surveillance Towers – Comprising fixed surveillance towers and a communications device that fuses the feed from UAVs and other sensors to provide 24/7 monitoring of an area of interest.
JERICHO – A portable communication system featuring GSM and satellite connectivity, along with an edge computer for real-time targeting and image transmission. It supports integration with unmanned systems and offers comprehensive data management and immediate response capabilities in the field.
StrikeWeb – Autonomy and Command and Control suite enabling automated mission planning and execution across sensor and effector platforms.
Strike:
OSIRIS – A plug-and-play, GPS-denied navigation module that enables UAVs to autonomously operate with near-zero geolocation error.
Interceptigon-A – Fixed‑wing kamikaze UAV delivering covert, high-speed swarms optimized for coastal and terrain-embedded launches.
Interceptigon-N – Stealth USV designed to lie in waiting on the seabed, surfacing autonomously to neutralize maritime threats.
M4K15 – Electronic Warfare to neutralize the threat from incoming UAVs.
What Comes Next
Delian is establishing a cross-European industrial and talent footprint, expanding its engineering and field deployment teams to meet growing demand from NATO and partner democracies. The company is also scaling its engineering and deployment efforts across multiple regions while investing in R&D to enable operations in contested, GPS-denied environments.
The future of autonomous defense is being built now. Europe cannot afford to wait to be saved.
