European Deep Tech in 2025: Why the Continent's Moment Has Arrived

For most of the past two decades, the standard narrative about European technology has been one of unfulfilled potential. Europe has world-class universities, deep pools of technical talent, and sophisticated industrial customers. And yet, the continent has consistently failed to produce the breakout technology companies that define the global landscape. The reasons cited are familiar: fragmented markets, conservative capital, risk-averse culture, and an inability to attract and retain the best talent when Silicon Valley and New York offer higher compensation and more dynamic environments.

That narrative is changing. At KnownWeil Capital, we have spent the past year conducting a systematic review of the European technology ecosystem to update our own investment thesis and assess whether the structural shifts we are observing are durable or transitory. Our conclusion: 2025 represents an inflection point for European deep tech, and the factors driving this change are more structural than cyclical.

The Talent Equation Has Shifted

The most important structural change in the European ecosystem is the talent equation. Over the past five years, a generation of European engineers, product managers, and operators who built their careers at companies like Spotify, Adyen, Klarna, Deliveroo, and N26 have begun founding their own companies. This is the same talent cycle that Silicon Valley has benefited from for decades — the diffusion of experience, networks, and capital from one generation of successful companies into the next — and it is now happening at meaningful scale in London, Berlin, Stockholm, Paris, and Amsterdam.

This generation of founders is different in important ways from the European founders of a decade ago. They have operated inside companies that scaled from seed to IPO. They understand how to build globally from the beginning, because the companies they worked for were global from the beginning. They have extensive networks in the US, because their employers competed there. And many of them are returning to Europe after stints in Silicon Valley with a more sophisticated understanding of how the best technology companies are built.

The talent pool is also being replenished by a sustained increase in the quality of European technical education. Imperial College London, ETH Zurich, Ecole Polytechnique, TU Berlin, and KTH Stockholm are producing engineering graduates who compete for roles at the best US companies and win them. Increasingly, these graduates are also founding companies in Europe rather than emigrating. The data on this is compelling: the number of PhD-founded deep tech startups in Europe has increased by over 40 percent in the past three years, with the highest concentrations in computational biology, quantum computing, and materials science.

Capital Is Arriving in Larger Quantities

The European venture capital ecosystem has historically been criticized for a shortage of capital at the growth stage — seed rounds were available but growth-stage companies were forced to rely on US investors who often imposed American norms on European businesses. That constraint is loosening materially.

Several dynamics are driving this. First, the success of the previous generation of European technology companies has created a new class of European technology billionaires who are deploying capital into new ventures. The founders of Adyen, Skype, Supercell, and Klarna have collectively invested in hundreds of new companies and created new funds that deploy with a distinctly European perspective. Second, major US venture funds have opened European offices at unprecedented rates, providing local coverage and the possibility of larger rounds. Third, the sovereign wealth funds and family offices of European financial institutions have dramatically increased their allocations to technology investing, both directly and through fund-of-funds commitments.

The result is that European technology companies today face a meaningfully different financing landscape than their predecessors. Seed rounds are larger, follow-on financing is more reliable, and the path to a US-standard Series B or C is less dependent on the decisions of a handful of Sand Hill Road partnerships.

Regulatory Clarity as a Competitive Advantage

The most surprising element of the European deep tech thesis — and the one that most distinguishes our current view from the consensus — is the role of regulation. For most of the past decade, European regulation has been characterized as a burden: GDPR compliance costs, AI Act uncertainty, and financial services licensing requirements have all been cited as factors that disadvantage European startups relative to their American or Asian counterparts who operate in more permissive environments.

We see this dynamic reversing. The countries and companies that have invested heavily in regulatory compliance infrastructure are positioned to win in a world where regulatory requirements are proliferating globally, not just in Europe. A European company that has built GDPR-compliant data architecture from the beginning, that has a track record of working constructively with regulators, and that understands how to operate within a complex multi-jurisdictional framework has a genuine competitive advantage in selling to large enterprise customers worldwide who face similar regulatory requirements in their own markets.

The AI Act, initially viewed as a constraint on European AI development, is producing a new generation of "AI assurance" companies that help organizations document, test, and audit the AI systems deployed in their operations. These companies are building products that will be essential for compliance not just in Europe but in any jurisdiction where AI regulation is enacted — and AI regulation is coming to most major economies. European companies have a 24-to-36 month head start on building the expertise and the products that this wave of regulation will require.

The Sectors We Find Most Compelling

Based on our analysis of the ecosystem, we are most actively investing in three areas within European deep tech. First, industrial software: Europe's industrial base is vast, deeply underdigitized, and increasingly under pressure from geopolitical factors that favor reshoring and supply chain resilience. The market for software that improves the efficiency, flexibility, and visibility of industrial operations is enormous, the incumbents are weak, and European founders have structural advantages in understanding the customer.

Second, fintech infrastructure: European financial services is one of the most complex regulatory environments in the world, and the companies building infrastructure to help financial institutions navigate it are building moats that are genuinely difficult to replicate. The continued fragmentation of European banking across national systems creates persistent demand for cross-border payment, compliance, and treasury management solutions that companies like our portfolio company Fenix Finance are addressing.

Third, AI for science: the intersection of machine learning and natural sciences — computational biology, materials discovery, climate modeling — is producing a wave of companies that have the potential to be among the most impactful technology companies of the next decade. European research institutions are disproportionately strong in these areas, and the founding teams emerging from ETH, EMBL, and Cambridge are among the most compelling we have seen anywhere in the world.

What Has Not Changed

A balanced assessment of the European opportunity requires acknowledging what remains structurally challenging. Enterprise sales cycles in Europe remain long and relationship-intensive. The talent market for senior commercial executives — specifically VP Sales and CRO candidates with a track record of scaling B2B SaaS businesses — remains thin outside London. Access to the US market requires deliberate investment in distribution that European founders sometimes underestimate.

And the cultural dynamics around risk and failure have improved but not been transformed. The stigma of a failed startup is lower than it was a decade ago, and the ecosystem has developed enough role models of second-time founders who succeeded after an initial failure. But the tolerance for prolonged uncertainty and the appetite for high-risk, high-conviction bets that characterize the best Silicon Valley investors and founders has not fully diffused into the European mainstream.

These structural challenges are real and deserve consideration. But they do not change our fundamental assessment: Europe's moment in deep technology has arrived. The companies being founded today by the continent's best technical minds, backed by increasingly sophisticated capital, competing in categories where European characteristics are advantages rather than handicaps, represent some of the most compelling seed-stage investment opportunities we have seen in our careers.

KnownWeil Capital is investing with conviction into this moment. Our portfolio reflects our belief that the next generation of defining technology companies will be built in Paris, Berlin, London, Stockholm, and Amsterdam as readily as in San Francisco. We are looking for the founders who share that conviction and are building accordingly.

The Role of European Culture in Deep Tech

One underappreciated dimension of the European deep tech advantage is cultural. European engineering culture has historically placed a premium on precision, depth of expertise, and technical rigor that aligns particularly well with the demands of deep technology development. The shortcuts and speed-to-market optimizations that work well in consumer internet — where speed of iteration often matters more than depth of technical foundation — can be actively harmful in deep tech categories where the wrong architecture or the wrong approach to a fundamental scientific problem can set a company back years.

This cultural premium on rigor manifests in several observable patterns. European deep tech founders tend to have longer educational backgrounds and deeper domain expertise at founding than their consumer internet counterparts. They are more likely to have published research, to hold patents, or to have built their expertise through decade-long careers in specialized industrial or scientific domains. These characteristics create a different starting point for company-building — less speed in early iterations, more durability in the core technical assets that determine long-run competitive position.

The European relationship with failure has also shifted in ways that enable deep tech company-building. Deep tech companies characteristically fail slowly — the scientific hypothesis that underpins the business may take three to five years to validate or refute. European investors and founders who have become more comfortable with prolonged uncertainty are better positioned to support deep tech ventures that require patient capital and extended development timelines before commercial traction is achievable.

The government and institutional support environment for European deep tech has also improved meaningfully. European research councils, national innovation agencies, and pan-European programs like EIC Accelerator have become more sophisticated in how they identify and support commercially-oriented deep tech ventures. The integration between academic research institutions and the commercial venture ecosystem — facilitated by dedicated technology transfer offices, proof-of-concept funding, and entrepreneur-in-residence programs — is more developed than at any previous point in European history.

Looking Forward

Our conviction about the European deep tech opportunity is not a claim that every sector or every company will succeed. Venture capital in deep technology carries substantial risk, and the long development cycles of deep tech ventures mean that the full consequences of today's investment decisions may not be known for five to ten years. Many of the companies that appear promising today will encounter scientific or commercial obstacles that prove insurmountable.

What we do believe is that the structural conditions for European deep tech success have improved more significantly in the past three years than at any previous point in the history of the European technology ecosystem. The talent is deeper, the capital is more available, the regulatory environment is becoming a competitive advantage, and the cultural conditions for patient, high-conviction company building are more favorable. These conditions will not persist indefinitely — capital cycles and talent availability fluctuate — but they are sufficiently strong today to justify concentrated, high-conviction investment in European deep technology companies at the seed stage.

A Note on Geographic Concentration

One practical implication of our thesis for founders is the question of where to build. We are frequently asked whether European deep tech companies should move to the United States at the seed stage to access deeper capital markets, larger talent pools, and proximity to the largest enterprise buyers. Our view is nuanced. For the first three to four years of a deep tech company's life — the period during which core technology is validated and initial product-market fit is established — there is limited benefit to being based in the US and potentially significant benefit to being close to European research institutions, industrial partners, and the talent that has built careers at European deep tech companies.

The calculus begins to shift as companies approach Series A. Enterprise sales into large US accounts requires a US presence. Access to the larger pool of Series A and growth capital in the US requires familiarity and relationships with US investors. And the talent required to scale commercial teams — experienced VP Sales candidates, enterprise marketing professionals with specific domain expertise — is more readily available in major US technology hubs than in most European cities.

Our portfolio companies have generally followed a model of building core technology and initial commercial traction in Europe, then establishing a US commercial presence when they are ready to begin a US enterprise sales motion. This sequence has worked well for the three companies in our portfolio that have completed the transition. It allows founders to preserve their ties to the European technical and research ecosystem — which often remain valuable even as the commercial focus shifts westward — while building the US relationships and capabilities required to access the world's largest enterprise technology market.
