In February 2026, Dealroom and the NATO Innovation Fund published a finding that would have been unthinkable five years earlier: European defence, security and resilience startups raised $8.7 billion in venture capital in 2025, up 55 per cent year on year. But for anyone thinking about where to actually work in this industry, the more interesting question is where it landed.
It did not land evenly or randomly. The funding, the talent and the government contracts are concentrating in a handful of cities, each developing a distinct specialisation. This matters if you are planning a career in European defence tech, because the city you choose will shape what sector you work in, how portable your skills are and how many options you have if your first employer does not work out.
We track over 430 defence technology companies across 31 European countries on our interactive map. Plotting them reveals something that spreadsheets miss: the clustering is sharp. Some cities have dozens of companies within commuting distance. Others have one or two isolated outposts. That difference determines whether you are joining an ecosystem or betting everything on a single firm.
Where the money and the missions meet
The six cities pulling in most of Europe's defence tech activity fall into two broad patterns. Some grew around venture capital and an existing deep-tech talent pool. Others grew because a government made itself unusually easy to sell to.
Munich is the clearest example of the first pattern. The city and its surroundings now host 42 VC-backed defence startups, according to Dealroom and the NATO Innovation Fund. They raised $1.7 billion in 2025 alone, an 18-fold increase since 2020, and carry a collective valuation of $22.7 billion. Germany overall attracted $2.1 billion in defence tech funding last year, with Munich accounting for the vast majority of it.
Munich has reached a density where career portability is real. Helsing, which builds AI for fighter jets and autonomous drones, currently lists 27 open roles. Quantum Systems, a tactical drone manufacturer, has 11. Isar Aerospace, which is developing launch vehicles, has 21. ARX Robotics, which builds autonomous ground platforms, has two. If you are an AI or robotics engineer in Munich and your startup runs out of runway, you can walk into interviews across the city without packing a single box. That mobility does not exist in most European defence hubs, which changes how much risk you can afford to take on an early-stage company.
Munich's specialisation runs deep into AI, autonomy and the air domain. It is where Germany's defence AI capability is being built, and where the largest share of national VC funding (over 15 per cent of all German venture capital) now flows toward defence, security and resilience companies.
Tallinn exemplifies the second pattern. Estonia's defence tech scene did not grow from a VC cluster. It grew because the government became the industry's first customer. The country's defence budget is set to reach 5.4 per cent of GDP from 2026, roughly triple the NATO target, and the Ministry of Economic Affairs launched a €100 million Defence Fund managed by SmartCap to invest directly in defence startups and funds. The procurement pipeline from idea to contract is shorter in Estonia than almost anywhere else in Europe.
Milrem Robotics, which builds the THeMIS unmanned ground vehicle, has 10 open roles and is one of the few European firms with combat-proven autonomous platforms. Frankenburg Technologies, working on air defence and missile systems, has three open roles. KrattWorks, which won DefenceTech of the Year at the 2025 Estonian Startup Awards, scaled from $728,000 in revenue in 2024 to $22.2 million in 2025 and grew from 22 to 68 employees. Cybernetica, the cybersecurity firm behind much of Estonia's secure digital infrastructure, has eight open roles.
Tallinn's specialisation is ground robotics, drones and the kind of software that runs on austere, contested networks. For engineers who want to build things that get fielded quickly, with a government willing to buy version one rather than waiting for version five, no other European capital comes close.
The prime-startup bridge and the procurement pipeline
Paris has something most European defence hubs lack: a direct bridge between the continent's large defence primes and its startups. In January 2026, Harmattan AI raised a $200 million Series B led by Dassault Aviation, the maker of the Rafale fighter jet. The round valued Harmattan at $1.4 billion, making it France's first defence unicorn. As part of the deal, Dassault will embed Harmattan's autonomy software into its combat aviation systems.
That kind of integration between incumbent and startup is rare in European defence. It is enabled partly by France's Agence Innovation Defence (AID), which acts as a structured on-ramp for startups into the French military procurement system. AID runs competitive grants, prototype contracts and testing programmes that give small companies a path to their first military customer without requiring them to navigate defence procurement alone. Across the broader ecosystem, French defence startups collectively raised more than €200 million in 2025.
Paris specialises in autonomy software, electronic warfare, ISR (intelligence, surveillance and reconnaissance) and the intersection of defence AI with legacy platforms. Exail, which builds maritime autonomous systems, has eight open roles. Stormshield, which provides military-grade cybersecurity, has 10. Harmattan AI, the new unicorn, has 23. For engineers interested in making AI work on existing military hardware rather than clean-sheet platforms, Paris is where that work is happening.
London leads Europe in raw defence tech investment: $2.9 billion in 2025 and $9.9 billion cumulative since 2020. The UK government consolidated its innovation apparatus in July 2025 by launching UK Defence Innovation (UKDI) with a ringfenced annual budget of at least £400 million, merging DASA, the Defence Innovation Unit, Command Innovation Hubs and DE&S Future Capability Innovation under one roof. Full operating capability is expected by July 2026.
US defence startups are also choosing London as their European beachhead. Second Front Systems opened its first overseas office there in 2023. Applied Intuition announced a UK expansion with a £50 million commitment in May 2025. The NATO DIANA Janus Accelerator, based in London's White City Innovation District, is running eight companies through its 2026 contested electromagnetic environments programme.
London's specialisation is AI simulation, defence software and the dual-use technologies that sit between commercial AI and military applications. It is also the strongest city for defence tech professionals who want optionality between the defence and commercial tech sectors, because London's broader tech economy means defence experience translates into adjacent roles more easily than in smaller, more specialised hubs.
The emerging contenders
Helsinki punches above its weight through a single company that has become one of Europe's most important defence assets. ICEYE, which operates the world's largest synthetic aperture radar (SAR) satellite constellation, launched an investment programme exceeding €250 million in 2025 to expand satellite manufacturing and develop optical and passive RF sensing capabilities. It raised €150 million in a Series E led by General Catalyst, with a further €50 million in secondary sales, at a $2.8 billion valuation. ICEYE plans to produce one satellite per week by mid-2026 and has 14 open roles in our database.
Helsinki's broader defence ecosystem includes Nokia (secure military communications), Bittium (tactical IT) and Patria's eALLIANCE programme for digital military capabilities. Finland's NATO membership since 2023 shifted the country's defence market from self-reliance toward interoperability, creating new demand for companies that can build systems working across alliance networks. Helsinki's specialisation is space-based intelligence and secure communications, a narrower niche than Munich or London but one with growing strategic importance.
Berlin is the most recent entrant. In late 2025, the Berlin Senate tasked Berlin Partner with building a DefTech ecosystem to connect research institutions, startups and policymakers. The city and its surrounding region have more than 400 companies active in dual-use technology according to Berlin Partner, and the Bundeswehr Cyber Innovation Hub (CIHBw), based in Berlin since 2017, runs innovation projects pairing startups with soldiers.
STARK Defence, a Berlin-based combat drone startup, has 13 open roles. But Berlin's real strength lies in the overlap between defence and the city's large civilian tech sector in cybersecurity, AI and cloud infrastructure. Berlin had 218 financing rounds across all sectors in 2025, more than any other German city. For engineers working in cyber, cloud security or dual-use AI who want to move toward defence without leaving behind their commercial experience, Berlin offers a transition path that more specialised hubs do not.
Choosing a city, choosing a career
For anyone evaluating a career in European defence tech, the right question is not which city has the most jobs today but which city fits the career you want to build.
If you want deep AI and autonomy work with maximum career portability, Munich has the density. If you want to build hardware that gets into soldiers' hands fast, with a government willing to take risks on startups, Tallinn offers something no other European capital does. If you want to work at the boundary between legacy defence primes and new technology, Paris is where that bridge is being built. London gives you the broadest optionality and the largest pool of capital. Helsinki is the place for space and secure communications. Berlin is where defence meets dual-use, with the easiest on-ramp from commercial tech.
