No battery exists without electrochemistry. No satellite survives orbit without radiation-hardened substrates. No fusion reactor holds plasma without materials that can endure temperatures above 2,000 degrees Celsius. Materials are the bedrock under every deep tech vertical, yet they remain the most undervalued sector in European venture capital.

That is starting to change. The European Research Council has funded 1,503 advanced materials projects worth EUR 2.37 billion since 2014, spanning health, electronics, and energy. Brussels is preparing an Advanced Materials Act, expected in Q4 2026, to accelerate the leap from lab to industrial deployment. And a new generation of advanced materials startups is compressing discovery timelines from decades to months.

Here is what is driving the shift, and the ten European companies leading it.

Why Advanced Materials Are Deep Tech's Most Overlooked Vertical

Advanced materials underpin every industrial sector, but they have traditionally been the slowest to innovate. The average time from laboratory discovery to commercial material has been 10 to 20 years. That timeline made materials science a poor fit for venture capital's preferred return horizons, and the sector was largely left to corporate R&D labs and government research programmes.

The economics are shifting. Materials innovation is now attracting dedicated funding because three forces are converging: artificial intelligence is accelerating discovery, regulation is creating demand for new material classes, and geopolitical supply chain risks are making domestic materials capability a sovereignty priority. The ERC's EUR 2.37 billion investment is concentrated in three domains: health (36.5%), advanced electronics (36.5%), and energy (19%), all areas where Europe needs next-generation materials to compete.

AI-Driven Materials Discovery: The New Paradigm

Machine learning is the single biggest catalyst for change in materials science. AI models can now predict material properties, from thermal conductivity to mechanical strength, before a single experiment is run. Combined with high-throughput experimentation (HTE), the automated parallel testing of hundreds of compositions simultaneously, and self-driving labs (SDL), fully autonomous robotic laboratories that design, execute, and learn from experiments without human intervention, the result is radical compression of discovery cycles.

The numbers are striking. According to Forbes, AI can reduce the time to market for new materials from roughly 20 years to less than 18 months. Demand for rare earths and critical minerals is projected to increase five-fold by 2030, making alternatives discovered through AI materials discovery not just commercially attractive but strategically essential.

Three European startups are leading this wave:

• CuspAI (Cambridge, UK) has raised over $100 million in Series A funding, co-led by NEA and Hoxton Ventures, and is approaching a $1 billion valuation barely a year after founding. The company uses AI to discover novel materials for climate and energy applications, with a partnership with Hyundai already announced.

• Altrove (Paris, France) operates an AI-driven synthesis lab with automated workflows and proprietary X-ray characterisation. With $14 million raised to date, led by Alven with Contrarian Ventures and Bpifrance, Altrove is developing rare earth alternatives for automotive, defence, and electronics customers.

• Dunia (Berlin, Germany) runs IRIS, a third-generation self-driving lab combining physics-informed AI with chemical robotics. Backed by $11.5 million in Series A funding from Elaia, redalpine, and the EIC, Dunia is targeting clean energy catalyst discovery, cutting timelines from decades to days.

Circular Materials and the Regulatory Push

Technology is only half the story. Regulation is creating equally powerful demand. The EU's Packaging and Packaging Waste Regulation (PPWR) responds to a stark reality: EU packaging waste reached 178 kilograms per person in 2023, with projections showing a 19% rise by 2030 without intervention. Alongside PPWR, Extended Producer Responsibility (EPR) schemes are forcing manufacturers to fund end-of-life management of their products.

Together, these regulations are creating a structural market for recyclable composites, bio-based polymers, and circular material feedstocks. Two startups are capitalising on this shift:

• Uplift360 (Bristol, UK) has raised EUR 7.4 million in seed funding, including investment from the NATO Innovation Fund. The company chemically regenerates advanced composite materials, including carbon fibre recovered from Eurofighter components, producing high-quality recycled aerospace feedstock for customers including Rolls-Royce, Leonardo, and Babcock.

• Cellugy (Aarhus, Denmark) has raised $15.2 million to develop cellulose-based rheology modifiers, replacing petrochemical-derived thickeners in coatings, adhesives, and personal care products with bio-based alternatives.

10 Advanced Materials Startups Redefining the Space

Across 50 European deep tech startups we track, materials companies stand out for their proximity to industrial deployment. Here are ten, grouped by the shift they represent.

AI Discovery

Circular and Bio-Based

Frontier Materials

Atinary Technologies in Lausanne integrates ML, robotics, and cloud computing into a no-code platform already deployed with Chemspeed Technologies and Takeda. Materials Nexus applies AI to predict optimal compositions, targeting industrial customers seeking faster formulation cycles.

In frontier materials, HTMS in Bristol produces Ceramic Matrix Composites capable of operating at 1,400 degrees Celsius, founded by former Rolls-Royce engineers. Arceon in Delft pushes further, engineering materials for temperatures above 2,000 degrees for hypersonic flight and atmospheric re-entry, backed by the Dutch Ministry of Defence through SecFund. Space Forge in Cardiff is manufacturing advanced semiconductors in microgravity, supported by GBP 22.6 million in Series A funding from the NATO Innovation Fund, World Fund, and the British Business Bank.

Holyvolt in Sweden completed the acquisition of California-based Wildcat Discovery Technologies for EUR 63.1 million, consolidating battery materials R&D under a European roof.

DTM.Materials: Where Corporate Buyers Meet Materials Innovators

Materials startups and their industrial customers are finally in the same room. DTM.Materials runs on 20 to 21 May 2026 at Wilhelm Studios in Berlin as part of Deep Tech Momentum, Europe's largest deep tech marketplace.

It is a marketplace, not a conference. Over 800 corporate R&D buyers, procurement leads, and materials investors will source technologies across four themes:

• AI materials discovery and informatics

• Autonomous and self-driving laboratories

• Circular polymers and bio-based alternatives

• Packaging transformation and PPWR compliance

Corporate attendees already confirmed include Henkel, Novartis, Schott, Beiersdorf, Sartorius, Sika, Avery Dennison, and Westlake. For R&D directors seeking to compress their own discovery cycles, this is the most concentrated gathering of advanced materials innovators in Europe this year.
