London has reclaimed its position as Europe’s top tech ecosystem, overtaking Paris in the latest Dealroom Global Tech Ecosystem Index 2026. Ranked fourth globally, the city remains one of the world’s top hubs as competition intensifies in the race to secure the next wave of AI and deep tech innovation.
The UK capital’s return to the top spot is driven by stronger venture capital investment, continued unicorn creation and its depth across sectors, reinforcing its position as Europe’s most established startup ecosystem. Last year, London tech companies raised £13.2 billion, whilst the city is now home to 138 unicorns, including Wayve, Granola, OLIX and ElevenLabs.
The UK ecosystem continues to show particular strength across AI, FinTech and life sciences, with London topping investment and scale of companies, while Cambridge and Oxford remain globally recognised centres for research-led innovation and university spinouts. Alongside AI firms such as Wayve and ElevenLabs, the UK has produced globally recognised FinTech companies including Monzo, Revolut and Wise, reinforcing its position as Europe’s top ecosystem.
Beyond London and Paris, Europe’s tech landscape is becoming more competitive and distributed. Munich is emerging as one of the continent’s top-performing ecosystems, underlining Germany’s growing influence in deep tech and industrial innovation. In particular, the city has become central to the boom in Europe’s defence tech ecosystem, with companies such as Helsing and ARX Robotics raising £569 million last year.
The continent dominates the global Density Leaders rankings, with 45 European cities featured in the global top 100, ahead of North America’s 40. The rankings measure innovation output per capita, including startup activity, enterprise value creation, unicorns and university linkages.
Cambridge is the third-highest Density Leader in the world, behind only the Bay Area and Boston, and number one in Europe, due to its combination of startup activity, research intensity and strong university partnerships. Oxford also continues to perform strongly as a global deep tech and life sciences hub.
Yoram Wijngaarde, founder & CEO of Dealroom.co, said: “London reclaiming the top spot in Europe reflects the maturity and resilience of the UK’s tech ecosystem. The city continues to attract global investment while producing internationally significant companies across AI, fintech and life sciences. At the same time, hubs like Cambridge and Oxford continue to punch above their weight through research and deep tech innovation, demonstrating the rise of high-performing smaller ecosystems that are shaping the future of technology.
“Our Index provides a transparent, data-driven benchmark to help leaders understand and accelerate that growth.”
