NEW DELHI: London has oႈcially reclaimed its position as Europe’s leading technology centre, overtaking Paris, according to the Dealroom Global Tech Ecosystem Index. In a social media post, London Mayor Sadiq Khan said, “London has reclaimed its position as Europe’s top tech hub, driven by investment in AI, ¿ntech and innovation”.
“This is a vote of confidence in our city, our talent and our businesses. We’ll continue to back growth, help create jobs and build a more prosperous London for everyone”, he added.
In 2024, London lost its position as the top tech ecosystem to Paris, but in 2025 it has reclaimed the top spot, powered by a record $7bn in AI investment, up from $3.9bn in 2024, the creation of new unicorns, and its depth across sectors, according to the new data.
In 2025, London tech companies raised $17.8 billion, up 45 per cent from 2024, with the city now home to 138 unicorns, including the likes of Wayve, Granola and ElevenLabs.
ChatGPT developer OpenAI is to make London its largest research hub outside of its San Francisco headquarters, while Anthropic recently announced plans for a major new London with capacity for 800 staႇ. London, ranked fourth globally, came in ahead of Paris, Stockholm, Berlin and then Munich across Europe.
Paris, home to AI startups like Mistral and the newer AMI Labs, raised $5bn in VC funding in 2025. The data shows that AI now accounts for around 30 per cent of VC investment in Europe, underlining the region’s focus on next-generation technologies.
The data also shows that Europe dominates the global Density Leaders rankings, with 45 European cities featured in the global top 100, ahead of North America’s 40. Cambridge ranks as the world’s third-highest Density Leader behind only the Bay Area and Boston.
The Density Leader rankings measure innovation output per capita, including startup activity, enterprise value creation, unicorns and university linkages. Yoram Wijngaarde, founder & CEO, Dealroom.co, said: “What stands out is not just the strength of leading hubs like London and Paris, but the rise of high-performing smaller ecosystems often built around leading research and academic institutions.”
