FenX Secures CHF 8.2 Million, Revolutionizing Sustainable Construction with Mineral Foam
October 3, 2025, 9:37 am
FenX, an ETH spin-off, secured CHF 8.2 million in Series A funding. This investment industrializes their groundbreaking mineral foam insulation. The technology offers a sustainable, non-combustible, high-performance, and cost-competitive alternative to conventional building materials. Made from circular inputs via a low-energy process, its lightweight panels are "stones made of ~98% air." FenX leverages an asset-light model, licensing technology and supplying additives. Key partnerships, including Çimsa commissioning a Spanish production line for late 2025 output, enable rapid global expansion. The funding fuels product line development, strategic alliances, and broader applications like carbon sequestration, targeting critical decarbonization of the global construction industry. This positions FenX as a cleantech leader.
The future of construction is here. FenX, an innovative ETH spin-off, just closed a CHF 8.2 million Series A funding round. This significant capital injection propels its groundbreaking mineral foam technology to industrial scale. FenX is poised to transform the global building materials market. Its sustainable solutions are critically needed.
Building insulation demands innovation. Traditional materials often fall short. They can be heavy, combustible, or environmentally taxing. FenX challenges this status quo. Their mineral foam offers a stark contrast. It promises superior performance with minimal environmental impact.
Imagine insulation panels that are mostly air. FenX calls them "stones made of ~98% air." This description highlights their incredible lightness. Yet, these panels deliver robust performance. They stand as a testament to material science ingenuity.
The technology's core benefits are compelling. FenX panels are non-combustible. They achieve an A1 fire rating. This offers unparalleled safety in buildings. They are lightweight, simplifying transport and installation. Their high performance ensures energy efficiency. Buildings stay warmer in winter, cooler in summer.
Sustainability drives FenX’s mission. The mineral foam uses circular inputs. This means waste materials are repurposed. The production process itself consumes minimal energy. This dramatically reduces its carbon footprint. It is a win-win for builders and the planet.
Cost-competitiveness remains crucial. FenX ensures its sustainable panels are affordable. They are designed to rival conventional options. This accelerates market adoption. Green building should not be a premium luxury. FenX makes it accessible.
FenX employs an asset-light business model. This strategy fosters rapid scaling. The company does not build massive production plants itself. Instead, it licenses its technology. It supplies specialized foaming additives to manufacturers. This empowers existing industry players. They can adopt FenX’s innovation efficiently.
Strategic partnerships are central to this model. FenX collaborates with machinery partners. MASA WhiteHub is a key ally. Together, they engineer production units. These units integrate FenX technology seamlessly. This ensures consistent quality and performance.
International expansion is already underway. Çimsa, a leading construction materials company, is FenX’s first customer. Çimsa is commissioning an industrial production line in Spain. This factory represents a major milestone. It will produce FenX-based mineral insulation panels.
Initial output from the Spanish plant is targeted for late 2025. This shows tangible progress. It validates FenX’s technology at full industrial scale. The Çimsa collaboration lays the groundwork for global growth. More partnerships with leading companies are expected.
The CHF 8.2 million funding round saw strong investor confidence. Supernova Invest led the round. Move Energy also played a significant role. Other participants included Zürcher Kantonalbank, Cimsa, 4see Ventures, buildify.earth, and various Swiss and French family offices. Their collective support underscores FenX’s market potential.
This capital injection serves multiple purposes. It enables FenX to further industrialize its mineral foam technology. This means refining processes and optimizing production. It accelerates strategic partnerships. New collaborations will expand FenX’s reach across geographies and applications.
Furthermore, FenX plans to launch additional product lines. The mineral foam platform is versatile. It extends beyond traditional insulation panels. The company actively explores broader applications. This foresight broadens FenX’s market opportunities.
Future applications include semi-structural materials. These could offer lightweight strength for various building components. Carbon sequestration is another exciting avenue. FenX aims to embed carbon capture capabilities within its materials. This would directly remove CO2 from the atmosphere.
FenX’s guiding principle remains clear. Maximize performance with minimal resources. This philosophy drives all their technology development. It positions FenX at the forefront of sustainable innovation.
The construction industry faces immense pressure. It accounts for over 30% of global CO2 emissions. Decarbonizing this sector is critical. FenX offers a powerful tool for this transformation. Its technology directly addresses this urgent environmental challenge.
FenX has already gained significant recognition. It consistently ranks among the Top100 Swiss Startups. It won Venture Kick. The company also participated in Venture Leaders Cleantech. These accolades highlight its innovative strength and potential.
The market demands better solutions. Fire safety is paramount. Energy efficiency is non-negotiable. Environmental responsibility is a societal imperative. FenX delivers on all fronts. Its mineral foam insulation stands ready to meet these challenges.
This Swiss-born cleantech startup is making waves. Its industrialization in Spain signals global ambition. FenX is not just selling a product. It is offering a paradigm shift. It is redefining what sustainable construction means. The built environment will be safer, greener, and more efficient. FenX leads this charge.
