Since 2021 to date, the European AI tech ecosystem has experienced strong growth, particularly in funding volume. According to the Tech.eu database, after a significant drop in investment activity in 2022, the market saw a notable recovery in 2023, followed by continuous year-over-year growth in funding.
Over the five-year period, the total amount of investment nearly doubled (from €2.2 billion in 2021 to €4.6 billion in the first ten months of 2025), while the number of deals remained relatively stable. The average deal size more than doubled, indicating growing investor confidence in scaling existing companies rather than supporting early-stage startups, a shift aimed at ensuring sustainable growth.
In this period, European AI startups had collectively raised around €13.2 billion in funding, with France, Germany, and the UK emerging as key development hubs. French AI companies alone raised over €4.1 billion, followed by Germany with €3.4 billion and the UK with €2.5 billion. This influx of capital has fueled a new generation of European AI “unicorns” and even “decacorns,” showing that Europe’s AI scene is maturing rapidly and becoming globally competitive.
Looking at the 2025 data (first ten months), investments in AI companies amounted to €4.6 billion. This year was particularly marked by mega funding rounds, such as the €1.7 billion investment in France’s Mistral AI in the third quarter of 2025, led by corporate giants ASML and Nvidia. That single deal alone drove a significant growth (approximately 37 per cent) in European AI funding in 2025.
The most highly funded European AI companies between 2021 and 2025 span a broad range of applications, from generative AI content creation to enterprise automation and defence technology. These companies illustrate how Europe’s AI strengths have diversified and deepened, confirming that Europe now has its own major AI technology players.
