June 2025's top 10 European tech deals you need to know about

In June, European tech companies raised a total of €6.5 billion across 323 deals, an 18 per cent increase from May’s €5.5 billion and 341 deals. 
The UK continued to lead the charge, raising €1.8 billion in June, up from €1.4 billion in May. By consistently raising the highest funding volumes, the UK is poised to remain a central hub for tech investment, particularly in fintech and AI.

June saw fintech take centre stage, though with a lower total of €957.1 million, suggesting a broader but slightly shallower interest in the sector.

Jon Ferguson, Partner at AshGrove Capital, commented on the June numbers within the European tech investment landscape in our June Tech.eu Pulse, a compact version of the monthly report:

While conditions remain selective, capital is still flowing to companies with strong fundamentals and a clear path to profitability.
