Each week, I track the most consequential startup developments across the European ecosystem to help financial professionals cut through the noise and focus on what matters for deal flow, sector positioning, and capital deployment. This week delivered a particularly rich set of signals — spanning nuclear energy, tax automation, payments infrastructure, AI governance, and deeptech — that deserve serious attention from anyone allocating capital to or around European innovation. Here is what stood out.
The headline transaction of the week belongs to Newcleo, the Italian nuclear cleantech startup that announced plans to go public on Nasdaq through a SPAC merger with NewHold Investment Corp III in a deal valued at $2.4 billion. For European deeptech watchers, this is a landmark moment — it signals that nuclear innovation emerging from Southern Europe can attract US public market appetite, and it raises important questions about whether more European cleantech assets will seek Nasdaq listings over domestic exchanges.
On the fintech side, Fonoa, the Croatian-founded, Dublin-based tax automation platform, closed a $110 million Series C and simultaneously acquired PwC’s Indirect Tax Edge platform. This is a textbook example of a growth-stage company using fresh capital not just for organic expansion but for strategic consolidation, folding in Big Four infrastructure to accelerate enterprise penetration. For investors tracking B2B fintech, Fonoa’s combined move is one of the more sophisticated capital deployment stories of the quarter.
Silverflow, the Dutch payment processor, secured a €37 million funding round as its transaction volumes approach one billion annually. The payments infrastructure layer in Europe continues to attract significant institutional interest, and Silverflow’s trajectory suggests that cloud-native processing architectures are gaining real commercial traction against legacy rails — a trend asset managers with fintech exposure should be monitoring closely.
In AI governance, UK-based Geordie AI raised $30 million in a Series A to expand its agentic AI security and governance platform. As enterprises accelerate autonomous AI deployment, the security and compliance layer is emerging as a structurally critical — and investable — category. This round reflects growing investor conviction that AI governance is not a nice-to-have but a boardroom necessity.
Orbital Industries, the London-based startup building AI-driven industrial hardware, closed a €43 million Series B. With data centre demand continuing to surge across Europe, companies operating at the intersection of AI and physical infrastructure are attracting growth-stage capital at an accelerating pace — a theme that will likely intensify through 2026.
From the Netherlands, Eddy Grid raised €7.5 million in a Series A after reporting nearly 900% revenue growth. Energy optimisation platforms are becoming critical infrastructure as grid pressure mounts across Europe, and that revenue growth rate will turn heads among growth equity investors looking for early-stage compounders in the energy transition.
Berlin-based Peec AI reached $10 million in annual recurring revenue just 16 months after launch, offering an AI visibility analytics platform for brands navigating the rise of AI-native search. The speed of this revenue ramp in a nascent but fast-moving category is precisely the kind of commercial signal that early-stage VCs and growth funds track as a leading indicator of category maturation.
On the fund side, Marvelous and the Joachim Herz Foundation launched a €20 million deeptech fund targeting early-stage innovation in Germany, specifically aimed at bridging the commercialisation gap. Germany’s deeptech pipeline remains underleveraged relative to its research base, and dedicated early-stage vehicles like this one are essential to converting lab-stage assets into investable companies.
Finally, MokN, the French cybersecurity startup, closed a €12.9 million Series A to scale its credential theft protection platform. With regulatory pressure on cyber resilience intensifying across the EU, enterprise cybersecurity remains one of the most defensible investment categories on the continent.
Taken together, this week’s activity confirms that European startup capital markets are operating with genuine momentum across multiple sectors simultaneously — from nuclear energy and payments to AI governance and deeptech manufacturing. For investors, the consistent thread is that the most compelling rounds are no longer concentrated in a single geography or vertical, but distributed across a maturing, multi-speed ecosystem that is increasingly capable of generating exits at global scale.
