The number of European startups in the climate tech sector just hit 30,000, doubling the number of US ones, as reported by Dealroom. Munich appears to be a major hub for volume and maturity within climate resilience, with the highest number of early-stage and Series B+ companies, like Marvel Fusion and STABL Energy.
In a conversation with TFN, Flore de Durfort, CEO & Co-founder at Atmen, a RegTech company providing the data infrastructure to certify green industrial products, shares: “Munich has a high concentration of nerdiness, which is a huge advantage for us. The proximity to research institutions and large tech champions like Infineon, Google, or Airbus creates porosity, so we have access to specialised talent pools. That deep tech talent is crucial for our success”
The second city in the race is Oxford, which excels in the academic-to-startup approach. The same report from Dealroom indicates over 100 climate tech spinouts launched from the university ecosystem in recent years.
Adam Tomassi-Russell, Director of Climate, Deep Science Ventures (DSV), informs TFN: “The UK, particularly the Oxford ecosystem, is positioned to lead the charge towards a clean climate future, setting an international standard. We combine high academic standards with an inherent agility and adaptability to the global norm.”
And the last one in this race is Paris, with deals totalling over €2B in Paris-based climate tech companies announced during the previous 18 months, thanks in part to the city’s central role in policy and capital flows.
The bottleneck: scaling amidst structural challenges
Nevertheless, the landscape presents several challenges, especially for hardware startups in terms of the capital intensity of industrial innovation. As a vivid example, median late-stage round sizes in Munich exceeded €70M in 2024.
Prof. Sid Pourfalah, CEO and co-founder of Concrete4Change, an award-winning R&D company on a mission to decarbonise the concrete and construction industest, notes: “Scaling a hardware-driven solution with long testing cycles and industrial requirements is capital-intensive. We’re addressing this through blfinished finance… and by forming industrial partnerships that de-risk the commercial rollout.”
Adding more to this are regulations and adoption in the construction and chemical sectors. Tomassi-Russell explains, “the translation gap from research to scale-up remains significant amid regulatory lag and fragmented standards in new fields like green chemistest and biotechnology.”
And in energy infrastructure, being digital and innovative is a must. Taco Engelaar, SVP at Neara, adds, “Europe is home to some of the world’s most ambitious climate goals, more than 40% of the EU’s energy consumption must come from renewables by 2030… This creates a critical demand for climate tech solutions that can deliver practical, scalable impact by modernising infrastructure and enabling smarter integration of renewables.”
Customer demand, talent, and operational scale
Since 2019, the European climate tech sector has seen over €30B investment flow. Yet two challenges persisted: finding operational talent and landing first-adopter customers for large-scale solutions (in particular).
Sam Hill, an Investment Analyst with TDK Ventures, shares, “Two of the hugegest challenges climate tech start-ups face in the UK/EU right now are finding talent and acquiring early customers, especially those willing to be first adopters… The talent gap isn’t so much about technical abilities, but more about operational experience in building large companies.”
Puja Balachander, co-founder and CEO, UpGreen, a startup that creates retrofitting simple, cost-effective, and stress-free, illustrates how UpGreen addresses practical hurdles faced by the built environment: “The greatest barriers we face are primarily related to the increasing required for compliant retrofits and the inability to carry these out. Our AI-powered retrofit platform reduces management and admin costs by up to 66%, coordinates complex stakeholder interactions, and delivers immediate energy bill savings for tenants, streamlining a historically complex process
French, German, and UK ecosystems are actively tapping blfinished finance and cross-border industrial alliances to close these gaps, leaning into purposeful, impact-driven work cultures to attract and retain talent.
The next growth frontiers: What’s hot (and why)
One thing is clear: Europe’s next billion-euro opportunities are emerging at the intersection of infrastructure, digitisation, and material science. Durfort emphasises: “One major growth area is climate tech as essential infrastructure, not a nice-to-have. Grid-connected assets, reliable data layers, and climate-focutilized finance systems are coming becautilize they’re critical for business.”
Tomassi-Russell spotlights deep chemistest, diagnostics, and policy tech as critical new markets: “The scale of the problem demands urgent innovation in novel materials and green chemistest, advanced monitoring and diagnostics, bioremediation, and policy and regulatory tech… These areas are ripe for disruption, offering immense commercial potential alongside critical environmental and health benefits.”
At the same time, Engelaar calls digital optimisation foundational: “One of the most urgent growth areas is digital grid optimisation… Technologies like dynamic line rating, AI-powered infrastructure modelling, and physics-based digital twins are enabling utilities to unlock more capacity from existing grid assets safely.”
Balachander adds, “AI-powered predictive analytics, carbon savings generation, and circular economy platforms for material reutilize are critical growth verticals. These enable scalable, cost-effective decarbonization tailored to complex real estate requireds.”
And Pourfalah brings it back to material solutions and circularity: “We see four major growth areas: CO₂-utilisation in materials, material circularity and traceability, decarbonisation of construction, and localised manufacturing for net zero. Innovations like mineralising CO₂ in concrete provide measurable, permanent emissions abatement…”
It’s more than a market share
Europe’s climate tech leaders, Munich, Oxford, and Paris, aren’t racing for market share.. Their real prize is a resilient, sovereign innovation ecosystem. With founders and investors uniting market numbers and mission-driven ambition, this is Europe’s second chance, and possibly, its greatest.
