It was only last year when European tech investment meant cautiously recovering from the past. Capital held up, but deal volume fell to one of the lowest levels in a decade. As a result, investors became more selective. A narrower set of companies received larger checks, leaving everyone else with less room to compete.

In Q1 of 2026, that logic has sharpened. Zubr Capital’s view is that this is not a broad reopening of the market, but a deeper concentration of capital around sectors investors now treat as strategically important. Those include AI infrastructure, defence and dual-use technology, and deep tech with industrial relevance. The difference now is that Europe’s venture market is no longer just filtering for quality — it is increasingly filtering for strategic fit.

Q1 2026 Shaped by a Selection of Mega-Rounds

The numbers for early 2026 show a clear concentration of capital. Wavve closed its €1 billion Series D. The French frontier AI lab AMI raised about €890 million, which most consider a giant Seed round with a €3 billion pre-money valuation. Nscale secured €1.1 billion in new infrastructure financing, compared with roughly €700 million from a blend of equity and debt secured by Mistral. These four companies accounted for over €3.5 billion in the quarter by themselves.

Such deals didn’t happen in a vacuum. PLD Space raised €180 million, 9fin closed €148 million, Allica Bank raised €131 million, and Wonderful hit €129.8 million (at a €1.7 billion valuation). Upvest combined €78 million in equity with a €30 million debt facility into a single package. Taken together, €100M+ rounds were a defining feature of the quarter, not a one-off spike.

The trend continues with the Dutch iron fuel company RIFT closing €113.8 million. Only a part of that funding came from private equity, with the remainder tied to EU Innovation Fund support. This points to a broader structural shift. Some of the most ambitious European bets are increasingly financed through hybrid structures rather than conventional VC alone.

So much activity in Q1 2026 was shaped less by a broad return of risk appetite and more by capital being focused on a small number of large, high-conviction financings.

The Sectors Defining Europe’s New Capital Concentration

Many of the Q1 2026 sectors attract capital and are starting to look similar from an investment perspective. When you consider how AI infrastructure, defence, dual-use technologies, and industrial deep tech look on paper, they appear sharply different. However, most share similar characteristics that the current European funding environment rewards.

These sectors are capital-intensive, often tied to real-world systems and aligned with industrial and strategic priorities. As the market seeks larger, higher-conviction bets, these characteristics make them easier to underwrite at scale. The result is that European capital isn’t spreading evenly. It’s clustering around companies that combine technological depth with infrastructure-like relevance.

AI: From Models to Infrastructure, Agents, and Physical Systems

AI in Q1 2026 is not solely based on foundation models. Most deals are flowing into companies with a stack that is deepening in both directions. It extends downward into infrastructure and outward into the physical and operational systems where AI is beginning to do real work.

The infrastructure layer includes several important areas of activity. Encord closed a €50 million Series C for physical AI data infrastructure — the pipelines and tooling that support large-scale deployment. Interloom raised €14.2 million at Seed for enterprise AI knowledge infrastructure, while Tower.dev raised €5.5 million to build infrastructure for AI-driven data engineering workflows. These deals might not be the most visible, but they reflect how investors are supporting the underlying scaffolding of the AI stack.

Where the trends are the clearest is in the agentic layer of the quarter. Nexus, backed by General Catalyst and Y Combinator, raised €3.7 million at Seed for enterprise AI agents. Flexzo AI closed €10.3 million for an agentic AI workforce platform. Riplo raised €2.6 million for an AI operating system focused on consulting. Stacks raised €19 million in Series A funding for enterprise finance AI. All these deals point to a consistent pattern, demonstrating how AI is moving from assisting human decision-making to taking on operational tasks more directly.

The most important extension of funding in Q1 is AI used in physical systems. Trener Robotics raised €26 million in Series A funding for a platform that trains robot skills. Dexory closed €9.8 million for warehouse intelligence that blends robotics with real-time data. FLEXOO added €11 million for sensor-driven physical AI in industrial settings. From a macro perspective, these rounds signal a shift from the purely software-first AI wave. Capital is now flowing into solutions that integrate AI into systems that perceive, decide, and act in the real world.

AI in Q1 2026 feels different from a year ago because of the convergence of AI in infrastructure, agentic, and physical layers. The category is growing, but is also becoming more layered, more operational, and more closely tied to industrial systems.

Where Defence and Dual-Use Tech Gain Momentum

In defence, Q1 2026 moved from a single landmark deal to activity across the full stage spectrum. For example, Harmattan AI’s nearly €200 million Series B, backed by Dassault Aviation, signals that defence-linked AI is now attracting strategic capital on a larger scale. Frankenburg Technologies raised €30 million at Series A for missile defence, further reinforcing that trend. The same is the case for a cluster of early-stage bets on Twentyfour Industries, Occam Industries, and Mutable Tactics, all focused on drone autonomy and AI-driven defence platforms across Germany and the UK.

The stage spread matters. Defence has moved from a small number of specialist bets to appearing consistently from pre-Seed through growth rounds, often at the intersection of AI, robotics, and autonomy. The entire sector has shifted from legitimization to sustained investor momentum.

Industrial Deep Tech: Hardware, Compute, and Energy Systems

The third concentration point is the least visible, but also the most foundational. Industrial deep tech — compute hardware, advanced manufacturing, and energy infrastructure — is the physical layer that the rest of Europe’s strategic technology agenda runs on.

At the compute layer, Lace Lithography raised €34.5 million for chipmaking equipment and Optalysys closed €26.6 million for photonic computing. These are not software companies with hardware components — they are capital-intensive, long-cycle hardware businesses of the kind that has often sat outside mainstream venture investment preferences.

The industrial layer follows the same logic. Isembard raised €43 million for software-defined factories, embedding intelligence into manufacturing at the process level. Additive Drives closed over €25 million for 3D-printed motor technology at the intersection of advanced manufacturing and electrification.

In energy, Terralayr’s €112 million Series A for grid-scale battery storage was one of the quarter’s largest rounds outside the AI mega-tier. Photoncycle raised €15 million for seasonal energy storage, targeting one of the harder unsolved challenges in the energy transition.

What connects these rounds across three different categories is a shared capital profile: they are large, long-horizon bets tied to physical systems that cannot be built incrementally. In a market increasingly filtering for strategic fit, that profile is attracting larger, higher-conviction rounds at scale.

Signals investors should not miss, according to Zubr Capital

All Q1 2026 data suggest that most of the significant capital is concentrated in a small set of Western European markets, but the underlying investment themes are far more geographically distributed. Defence, AI infrastructure, robotics, and deep tech companies receiving such funding come from a broad swath of the region, spanning the UK, France, and Germany to Estonia (Frankenburg Technologies), Lithuania (WhiteBridge.ai, Axiology), Poland (Nomagic), Latvia (Deep Space Energy), and Bulgaria (Mandel AI).

Zubr Capital sees this as a signal that capital is clustering around sectors and capabilities rather than following a purely geographic logic. Investors looking to take advantage of such funding should prioritize thematic alignment over geography when uncovering new opportunities.

At the same time, hybrid capital has become structurally important. Q1 2026 reinforced the patterns of 2025. European tech financing has moved beyond traditional venture equity, with more companies combining equity with debt, grants, or public funding. For investors, this makes capital structure a more important part of the underwriting equation. In many cases, companies that can coordinate multiple financing channels may be better positioned to scale in a tighter market.

One final note worth considering is how AI is moving beyond models into more operational systems. An underappreciated signal in Q1 2026 is the speed with which AI is now integrated into applied systems. Trener Robotics, Dexory, FLEXOO, Allonic, Nature Robots, and Kilter all point to growing investor interest in companies applying AI in industrial systems, physical environments, and robotics. To Zubr Capital, this demonstrates a shift beyond foundation models. Businesses applying AI directly to real-world processes could represent the next wave of value creation.
