London has overtaken Paris and reclaimed its position as Europe’s leading tech ecosystem, according to the latest Dealroom Global Tech Ecosystem Index 2026.
Ranked fourth globally, London remains one of the world’s top hubs as competition intensifies in the race to lead the next wave of AI and deep tech innovation.
The capital’s return to the top spot is driven by stronger venture capital investment, continued unicorn creation and its depth across sectors.
Last year, London tech companies raised $17.7bn (£13.2bn) and is 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 leading in investment and scale of companies, and Cambridge and Oxford remaining globally recognised centres for research-led innovation and university spinouts.
Alongside AI leaders such as Wayve and ElevenLabs, the UK has produced globally recognised fintech companies including Monzo, Revolut and Wise.
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.
Europe 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 is 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.
“London reclaiming the top spot in Europe reflects the maturity and resilience of the UK’s tech ecosystem,” says Yoram Wijngaarde, founder and CEO at Dealroom.co. “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.”
