What Strong by Form does
Strong by Form (legal entity: Woodflow Technologies S.L.) is a privately held biomaterials company founded in 2018 and headquartered in Spain, with engineering operations in Stuttgart, Germany, and an office in Santiago, Chile. The company develops Woodflow®, a proprietary biomimetic engineered wood technology that uses fiber-steering software, computational design, and industrial additive manufacturing to transform timber into high-performance 3D components. Its core technology replicates nature's growth patterns by aligning wood fibers along specific stress lines, enabling complex double-curved geometries previously impossible with conventional timber processing. Strong by Form has two product lines: Woodflow-core, a prefabricated structural slab system targeting long-span construction as a 90%-lighter, cost-competitive alternative to reinforced concrete; and Woodflow-skin, a freeform interior cladding and architectural surface product composed of 88% natural wood at 6.9 kg/m². The company also develops mobility applications, including a stamped wood bicycle and components for automotive and mass-transit OEMs.
Strong by Form monetizes through a hybrid model combining direct hardware sales of Woodflow-skin, licensing and joint-development of Woodflow-core technology with mass timber manufacturers (Finsa, Pfeifer, CMPC), and exclusive distribution partnerships such as with The Wood Veneer Hub for the U.S. and U.K. Pricing is project-based and not publicly disclosed, though Woodflow-core is positioned as cost-competitive with reinforced concrete at scale. The company targets enterprise customers across construction (mass timber manufacturers, builders, architects, interior designers), mobility (BMW, Talgo, Alstom, NS rail, Deutsche Bahn for station infrastructure), and premium interiors (Bang & Olufsen, VINCI/Leonard, Giò Forma, Corporación Quiport for Quito airport).
The company has raised approximately $6.2M in disclosed funding across a 2018 friends-and-family round, a 2020 pre-seed, a 2021 round, and a €4.82M (~$5.2M) seed in December 2023 led by CMPC Ventures with participation from CiRio Ventures, Teampact.ventures, MAIF Avenir, VX Ventures, Climate Insiders, COREangels Climate, YAKU Partners, Symbia VC, Finsa, and Leonard (VINCI). It is preparing a €10M Series A in 2025 to support the Spanish pilot plant and European commercialization. Strong by Form has received over 20 industry awards, including the JEC Composites Startup Booster 2025 Sustainability Prize, the Cleantech Open Global Forum Award, the TechCrunch Disrupt Top 20 (2025), and inclusion in the SET100 List 2026.

Revenue model
- Woodflow-core product sales: Sale of Woodflow-core structural slabs to mass timber manufacturers and construction companies. The system enables prefabrication and green construction at the same cost as concrete, targeting the mass timber industry's expansion into a market 80x larger than its current addressable market.
- Woodflow-skin product sales: Sale of Woodflow-skin panels (both catalogue products and custom designs) for interior cladding applications. Distributed through The Wood Veneer Hub in U.S. and U.K. markets, with direct sales in Europe. Panels are priced per project based on custom specifications.
- Licensing of Woodflow technology: The company pursues a technology-led commercial model, partnering with established mass timber manufacturers and leveraging existing industrial capacity. Strong by Form provides technology licensing and co-development to enable mass timber producers to manufacture Woodflow-core components.
- Technology licensing and joint ventures: By working with the mass timber industry as a whole through joint ventures or assembly partnerships, the company can scale rapidly at a global level, empowering the industry to take wood to the next level with technology licensing.

Strong by Form product offering
Product offeringCore offering
Strong by Form develops Woodflow®, a proprietary biomimetic engineered wood technology that combines computational design, fiber-steering software, and industrial additive manufacturing to produce high-performance timber-based biocomposites. The company sells two main product lines: Woodflow-core, a prefabricated structural slab system that replaces reinforced concrete at 90% lighter weight, and Woodflow-skin, freeform interior cladding and architectural surface panels made from 88% natural wood. Products serve construction, mobility, and interior design customers including mass timber manufacturers, rail operators, and automotive OEMs.
Product overview
Strong by Form offers Woodflow®, a proprietary biomimetic technology platform that creates lighter, stronger, and more sustainable wood-based materials inspired by the structural efficiency of trees. The portfolio comprises two distinct product lines: Woodflow-core — a structural slab system for construction that replaces reinforced concrete at 90% lighter weight and cost competitiveness at scale — and Woodflow-skin — a freeform interior cladding and architectural surface material for interior design and cladding applications. Both products share the same underlying Woodflow® technology, which uses computational design and industrial additive manufacturing to optimize wood fiber architecture.
