London has reclaimed its position as Europe’s leading 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 lead 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.
