Fiber Elements is an Austrian deep‑tech startup that develops automated, 3D basalt‑fiber reinforcement structures intended to replace steel reinforcement in concrete, offering lower weight, higher strength and much lower CO₂ intensity than conventional rebar[3][6].
High‑Level Overview
- Mission: To decarbonize and redesign concrete reinforcement by replacing steel with automated, topology‑optimised basalt‑fiber structures that reduce embodied carbon and extend durability[3][6].- Investment philosophy (for an investment firm context): N/A — Fiber Elements is a portfolio company that raised a €2.6M seed round led by LEA Partners with Amadeus APEX Technology Fund as a backer to scale industrialisation and automation[3][5].- Key sectors: Construction materials, sustainable building systems, industrial digital manufacturing and composite materials for prefabrication[3][2].- Impact on the startup ecosystem: The company is an example of university‑born deep tech (Montanuniversität Leoben ecosystem), attracting VC for hardware+AI scaling and demonstrating how materials + automation can unlock lower‑carbon building components, thereby stimulating pilot projects and supplier innovation in prefab concrete markets[1][2].
As a portfolio company:
- Product: Automated production systems and digitally optimised 3D basalt‑fiber reinforcement components (continuous basalt fiber structures / non‑crimp fabrics and novel 3D load‑path reinforcements)[1][3].- Customers served: Early customers are prefabricated concrete manufacturers in Austria, Germany and Denmark; Fiber Elements was serving about five customers at the time of its seed raise[2][3].- Problem solved: Replaces steel rebar to cut CO₂ (reported up to ~70% reduction), reduce weight, and increase durability/strength of reinforced concrete components, while enabling automated, AI‑driven production workflows[2][3].- Growth momentum: Founded in 2023, completed pilot projects, moved into pre‑industrial/serial‑scale production, and closed €2.6M seed funding in 2025 to double headcount and accelerate automation and industrial scaling[1][2][3][6].
Origin Story
- Founding year and founders: Fiber Elements was founded in Leoben, Austria, in 2023 by architect‑turned‑entrepreneur Wolfgang Fiel (Founder & CEO)[1][3][6].- Key partners and ecosystem: The company emerged from the Montanuniversität Leoben start‑up centre and collaborates with TU Wien, BOKU Vienna and academic teams including Prof. Robert Galler, leveraging university research and regional startup supports like EIT Manufacturing programmes[1][2][3].- How the idea emerged: Fiel combined architectural/materials research with digital manufacturing insights to exploit basalt — a volcanic rock that can be drawn into continuous fibers — for load‑path‑oriented reinforcement that is amenable to automated, AI‑supported production and topology optimisation[1][3][4].- Early traction / pivotal moments: Early lab work led to pilot projects and pre‑industrial production; notable milestones include participation in EIT Manufacturing Venture Building, first customer pilots with prefab concrete manufacturers, and the €2.6M seed round in mid‑2025 to scale production and AI tooling[2][3][6].
Core Differentiators
- Material advantage: Uses continuous basalt fiber — a mineral fibre with lower embodied carbon than steel and reported high specific strength (company claims composites up to ~3× stronger than steel by strength‑to‑weight)[3][5].- Digital + manufacturing integration: Seamless digital workflow from FEA (finite element analysis) to AI‑driven fibre layout optimisation, enabling bespoke, load‑path‑oriented 3D reinforcements and real‑time product health monitoring/predictive maintenance[1][3].- Automation and scale ambition: Focus on fully automated production and plans for on‑site “nano‑factories” that reduce transport and speed deployment of prefab components[3][5].- Sustainability and lifecycle focus: Emphasis on life‑cycle analysis, bio‑based resin systems research, and demonstrable CO₂ reductions in pilot cases (claims of up to ~70% reduction vs. steel reinforcement)[1][2][3].- Academic & IP foundation: University spin‑out with research collaborations, at least one granted patent and multiple applications filed by 2025[3][6].
Role in the Broader Tech Landscape
- Trend alignment: Rides two converging trends — decarbonisation of heavy industry/construction and the digitisation/automation of manufacturing (digital twins, FEA‑driven design, AI optimisation)[3][6].- Timing: Construction faces regulatory and market pressure to cut embodied carbon and improve durability; the availability of industrial automation and AI design tools makes novel, fibre‑based reinforcement commercially plausible now[2][3].- Market forces in their favour: Strong demand from prefab concrete manufacturers seeking lighter, longer‑lasting and lower‑carbon components; investor appetite for climate‑focused deep tech; and a growing ecosystem of research centres supporting scale‑up[2][3][5].- Influence on ecosystem: Demonstrates a path for materials innovation to enter mainstream construction via pilots with prefab producers, potentially shifting supply chains away from steel and encouraging modular, factory‑based construction techniques[2][3].
Quick Take & Future Outlook
- Near term (12–24 months): Focus on industrialising production, completing certification processes, scaling customer pilots into serial supply, doubling headcount and further automating the digital workflow with AI as funded by the €2.6M seed round[3][6].- Medium term (2–5 years): If technical claims and certification/standards acceptance hold, Fiber Elements could roll out nano‑factory units for regional on‑site production, expand beyond prefabrication into broader structural applications, and increase patent/IP portfolio value[3][5].- Risks and dependencies: Key challenges include regulatory certification in construction, proving long‑term durability in diverse conditions, scaling manufacturing cost‑competitively versus steel rebar, and supply chain logistics for basalt fiber and resin systems[2][3].- Why it matters: By combining materials science, FEA design and automated manufacturing, Fiber Elements offers a concrete pathway to materially lower‑carbon, higher‑performance reinforced concrete — a proposition that, if adopted at scale, could shift significant emissions in the built environment and accelerate industrial adoption of digital, modular construction methods[3][2].
Quick take: Fiber Elements is a university‑rooted deep‑tech startup with validated pilot traction and venture backing, positioned at the intersection of low‑carbon materials and automated manufacturing; its near‑term success will hinge on certification, cost parity with steel reinforcement, and the pace of prefab industry adoption[1][3][6].
