Meet the European companies that raised the top 10 funding rounds in H1 2025; 6 are currently hiring

European technology companies are commanding attention on the global stage, with several securing massive funding rounds that place them among the world’s largest deals in 2025. This surge reflects a startup ecosystem that continues to attract investor confidence despite broader economic uncertainties.

According to Dealroom, European startups have raised nearly $28.9B (nearly €24.53B) across 3,600 funding rounds in the first half of 2025. The top 10 funding rounds alone accounted for over €3.8B, spanning sectors including artificial intelligence, defence technology, and pharmaceutical research.

This level of investment activity shows that investors are increasingly viewing European startups as companies capable of addressing worldwide challenges that are scaling to match their ambitions.

Munich-based Helsing exemplifies this trend, securing €600M to advance its AI-powered defence systems. The company’s success reflects growing recognition that European firms can compete directly with Silicon Valley counterparts in technology sectors. Similarly, London’s Isomorphic Labs, a DeepMind spinoff, raised an equivalent amount to support its approach to pharmaceutical development using AI.

These deals signal a shift in how investors perceive European tech capabilities.

The Global Startup Ecosystem Report 2025, however, reveals changes in European startup ecosystem rankings. London, despite its continued strength, slipped from second to third place globally for the first time since 2019. This shift doesn’t necessarily indicate decline, but rather reflects the competitive nature of global startup ecosystems and the rapid rise of other regions. Conversely, Paris has climbed to 12th position. This improvement stems from an increase in both large private companies and early-stage deals.

Meanwhile, the Ukrainian startup ecosystem has showcased remarkable resilience. Despite the war and economic uncertainty, the country’s venture landscape grew to include over 2,600 companies by the end of 2024. More than 18 per cent of these startups began after the conflict started, indicating continued activity and effort. Ukrainian startups collectively secured $462M in funding during 2024, with the top ten rounds accounting for $324.4M of this total. 

The companies driving these funding rounds are not simply accumulating capital—they’re actively expanding their operations and building teams across diverse skill sets. This expansion creates opportunities for professionals ranging from AI researchers and defence specialists to business development experts and operations managers.

For those looking to join Europe’s well-funded startups, understanding which companies secured the largest investments provides valuable insight into where the most dynamic growth opportunities may lie.

Below, we have compiled a list of the top 10 European companies that secured the largest funding rounds as of 2025, many of which are actively expanding their teams.
