What started as a niche academic research project has become a deep tech startup operating across Europe and Latin America, with millions raised in private funding and grants. Strong by Form developed Woodflow, a technology that turns natural timber fibers into 3D-formed structural materials, enabling strong, lightweight, and carbon-reducing alternatives to concrete, aluminum, and even steel.

Their design-driven approach doesn’t just replicate wood planks—it reimagines wood as a high-performance composite, shaped by nature's logic and modern computational design.

Though most of the founding team hails from Chile, the company was strategically incorporated in Spain to operate within Europe’s innovation and regulation ecosystem. Today, the team is 27 people strong and split across Chile, Germany, and Spain.

“Europe is tough on regulation—but it’s also where real scale is possible,” Andres explains.

Yes, their iconic waveform-style logo was sketched in five minutes. Yes, it was inspired by Joy Division. But that aesthetic also represents the undulating structural logic behind their composite designs. Andres’ co-founder Jorge, an architect-turned-engineer, originally developed the idea while studying at ETH Zurich. His mission? Create the lightest, most material-efficient structural slab possible—starting with carbon fiber but pivoting to wood for scalability and sustainability.

Strong by Form’s founding trio came together through long-standing friendships and complementary skill sets—engineering, digital fabrication, and startup acceleration. When Jorge and Daniel realized they had a revolutionary process but no path to market, they called Andres, who had just left venture capital. He joined to build the business—and soon they were securing grants, awards, and investor interest from forestry giants and mobility leaders alike.

At JEC 2025, Strong by Form unveiled a bike frame prototype made entirely from Woodflow, designed using composite logic rather than milled timber. It's a visual and functional proof that their stamped biocomposites can handle form, function, and strength—without carbon-intensive inputs.

“This bike isn’t a gimmick—it’s a signal. We’re building with wood the way carbon fiber is used in aerospace,” says Andres.

While construction remains their core focus, Strong by Form is expanding into automotive and micromobility. BMW was one of the first to express interest back in 2019—and is now working with the startup on large-scale, interior and exterior vehicle components. A million-euro grant is fueling development of their advanced pressing process, and they’re now actively engaging new partners in bikes, transportation, and e-mobility.

Strong by Form’s investor cap table is as unconventional as their tech: four corporate investors (including Europe’s top timber producers and construction leaders) and a mix of impact-oriented VCs. Andres admits they had to throw out the startup rulebook.

“The first thing you're told is to avoid corporates. Well, our first investor was a corporate,” he laughs.

The result is a founder journey that doesn’t follow Silicon Valley tropes—but proves that material science innovation can (and must) be funded differently.

What started as a DIY surfboard made from recycled cardboard quickly turned into a deep-tech material startup. François initially entered—and won—an innovation competition in California. But the surf industry was too niche, so he pivoted to a broader mission: replace carbon-intensive materials in furniture, mobility, and industrial design.

Airboard transforms recycled cardboard into composite sandwich panels, competing directly with wood, aluminum, and even honeycomb cores. Their breakthrough lies not just in the material—but in the machinery they’ve developed to treat and mold the waste without water or high energy use. The result: lightweight, strong, and fully moldable bio-based composites.

Unlike traditional manufacturers, Airboard isn’t building one big factory. Instead, they’re creating a scalable machinery platform, inspired by models like Tetra Pak, to enable local production at the source of waste. This distributed approach is designed to keep emissions low and business margins healthy.

Developing novel materials is hard. Developing machines to produce those materials is even harder. François shares how most of Airboard’s progress has been self-funded or bootstrapped—and why fundraising is now critical to accelerate R&D and scale production. The team is currently raising €2 million to build next-generation machines and meet growing demand.

Airboard’s journey was accelerated by attending JEC World 2024 as a visitor. There, François connected with Techstars, joined their sustainability accelerator, and gained exposure to investors and industrial partners. A year later, Airboard returned as an exhibitor—now part of JEC Startup Booster, the Innovation Planet, and the bio-based materials showcase.

• Bio-based & circular: They reuse waste without water or chemicals.
• Low-energy manufacturing: Their machines are analog, efficient, and easy to deploy.
• Custom shaping: Thanks to composites, the material can be molded into complex designs.
• No sanding: Their process eliminates time-consuming post-processing steps.

François isn’t chasing headcount or mass centralization. His vision is a network of local microfactories, embedded in places where cardboard waste is abundant. From automotive OEMs to IKEA-style furniture producers, he believes Airboard machines could sit within customer facilities, enabling on-demand, sustainable material production.

When asked what’s most needed for real sustainability in the composites industry, François doesn’t cite regulation or capital. He says: time. Time to think differently, to explore outside the box, and to develop better systems. “The most valuable thing in the world is time,” he says—something big manufacturers often lack.
