What A:GAIN does
a:gain ApS is a Danish circular building products company founded in 2021 as a spinout from Lendager Group. The company remanufactures discarded materials — production offcuts, demolition glass, industrial side streams, and post-consumer PET — into certified building products that meet the same performance, fire, and CE compliance requirements as conventional alternatives. The commercial product portfolio spans building envelope (Bronsø thermowood cladding, Viddø window elements), floors and walls (Funderø parquet, Hjælmø end-grain flooring, Tystø glass wall partitioning), and acoustics (Dybø acoustic batts), with three additional products (Nærø, Flarø FR, Ebbø) in active development. All SKUs carry EPD-verified LCA data, EU Taxonomy M5.1 documentation, and DGNB compliance evidence, with quantified CO2e outcomes such as 69% reduction for Bronsø versus virgin alternatives.
The business sells primarily through direct enterprise field sales to building owners, architects, and contractors, supported by a download center for specification documentation, price lists, and tender descriptions. Revenue is generated via project-based hardware sales priced by unit/format, with the largest disclosed customers including IKANO Bolig, Søren Jensen, Jeudan, NREP/Skanska, and Danica Ejendomme. Distribution is direct in Denmark and via a channel partnership with Green Square in Austria, the company's first international market. Strategic partners DEKO (manufacturing), Tscherning (demolition glass supply), and Junckers (installation guidance) anchor the production and supply chain. The company closed a €4 million seed round in March 2025 and employs a small team led by CEO Thomas Nygaard Hamann, with a leadership transition announced in May 2025.

A:GAIN product offering
Product offeringCore offering
A:GAIN designs, manufactures, and supplies circular building products made from secondary and waste material streams for use in construction and interior fit-out. Its product portfolio includes thermowood cladding, window elements, parquet and end-grain flooring, glass wall partitioning, and acoustic batts, all EPD-verified and CE-marked for use by professional builders and developers.
Product overview
A:GAIN operates as a circular building products company that remanufactures certified building products from secondary (waste) material streams. The product portfolio spans three main categories: Building Envelope (Bronsø thermowood cladding, Viddø window elements), Floors and Walls (Funderø parquet flooring, Hjælmø end-grain flooring, Tystø glass wall partitioning), and Acoustics (Dybø acoustic batts). All products are designed for professional construction with full EPD verification, CE certification, and compliance documentation. The company operates a take-back system for selected products (Fusø, Marø, Nærø) to ensure circularity. Several products are in development including Nærø acoustic batt, Flarø FR fire-retardant acoustic panel, and Ebbø acoustic panel. The portfolio demonstrates measurable CO₂e reductions (69% for Bronsø) compared to virgin material alternatives while meeting the same performance and compliance requirements as conventional building products.

A:GAIN competitors and assessment
Company assessmentDirect peers
- Durat: A Finnish manufacturer of recycled solid surface materials with a take-back programme. Durat's model of upcycling post-consumer plastic into certified architectural surfaces with circular lifecycle services mirrors a:gain's positioning and customer profile.
- StoneCycling: A Netherlands-based producer of bricks, tiles, and facade products manufactured from construction and demolition waste. Directly comparable to a:gain's Bronsø cladding in addressing building-envelope applications with documented circular content and architectural-grade certification.
- Plasticiet: A Netherlands-based manufacturer of recycled plastic building panels and interior products for commercial architecture. Closely comparable to a:gain's Tystø glass partitioning and acoustic product lines in using waste streams as feedstock for specification-grade architectural materials.
- Mater Design: A Danish circular design brand producing furniture and architectural products from waste and surplus materials. Mater shares a:gain's Danish heritage, sustainability positioning, and professional specification channel, making it a strong regional peer.
- Smile Plastics: A UK manufacturer of 100% recycled plastic panels for architecture and interior design. Like a:gain's Dybø acoustic batts and discontinued Fusø/Marø plastic boards, Smile Plastics upcycles waste plastic streams into certified architectural panels, serving the same specifier-driven customer base.
- Lendager Group: The Danish architecture and circular construction practice from which a:gain was spun out in 2021. Lendager continues to drive circular building materials and methods, sharing a:gain's design DNA, target customers (DGNB-focused developers), and materials philosophy. It is the closest comparable in category and geography.
Broad incumbents
- Interface: A global modular flooring leader with the well-known "Mission Zero" sustainability programme, recycled-content products, and ReEntry take-back service. Competes with a:gain for sustainability-driven commercial flooring specification while operating at far larger scale.
- Tarkett: A global flooring incumbent with explicit circular-economy programmes (recycled content, take-back/ReStart, EPDs). Tarkett overlaps directly with a:gain's Funderø parquet and Hjælmø end-grain flooring in product category, while its scale and broad portfolio make it a strategic competitor rather than a niche peer.
- Forbo Flooring Systems: A leading European manufacturer of resilient and bio-based flooring (including Marmoleum, linoleum-based products with high biobased and recycled content). Overlaps with a:gain's flooring portfolio in commercial specification settings and competes on documented environmental credentials.
Emerging players
- EcoCocon: A Lithuania-based manufacturer of straw bale wall systems for low-impact construction. A complementary emerging player in the European circular/natural building materials space, addressing the same sustainability-driven specification segment as a:gain but in a different building-envelope niche.
