We all know that artificial intelligence has moved beyond the hype phase and is now reshaping nearly every industry, from healthcare and finance to logistics, retail, and defence. Across Europe, this technology is here to stay, with billions flowing into platforms, applications, and infrastructure that power the next wave of intelligent systems.
Initiatives such as the EU AI Act and national strategies continue to promote ethical innovation, balancing technological progress with a commitment to trust, transparency, and safety. According to a recent study by Dealroom, Paris ranked as the world’s third most important hub for AI in 2025, behind only the Bay Area and New York. This marks a major milestone for Europe’s innovation landscape.
On that note, we have curated a list of 10 standout European startups that raised the largest AI funding rounds in 2025. From frontier model developers and AI cloud infrastructure providers to defence, biotech, and creative tech pioneers, these companies are defining the continent’s AI future while setting new records in investment and ambition.
First place
