Visibuilt, a Danish biotech company, has raised 3.34 million euros in seed funding to advance its mycelium-based binder technology, visiBINDER. The binder is designed to replace carbon-intensive materials like cement and bitumen in paving and infrastructure projects. The round was co-led by EIFO and Unconventional Ventures, with participation from Proptechfonden and EMDFonden. The company plans to use the funds to move from lab-scale pilots to larger production trials with industry partners, including a concrete paver manufacturer and Copenhagen Municipality. Concrete and asphalt production are major sources of global CO2 emissions. Visibuilt's approach uses the root structure of fungi to create a binder that can displace fossil-based alternatives in paving applications. The company claims each tonne of its binder used in paving replaces a tonne of fossil binder and generates royalty revenue while reducing embedded carbon. The seed round will support larger scale testing, production design validation, and team expansion as the company works toward market introduction.

Danish startup Visibuilt just closed a 3.34 million euro seed round for mycelium based binders meant to replace cement and bitumen in paving. They already have testing relationships with a concrete paver manufacturer and Copenhagen Municipality. Worth a read if you follow low carbon construction materials.

The bit about every tonne of visiBINDER displacing a tonne of fossil binder and generating royalty revenue is interesting. If the unit economics hold at scale, that is a rare case where the climate impact and the business model are the same thing.

I want to see the durability data for outdoor paving. Mycelium based materials have had trouble with moisture and freeze thaw cycles in the past. If they can prove it holds up in a Danish winter, that is a real signal.

They mention testing with a concrete paver manufacturer and Copenhagen Municipality. That suggests they are already doing real world trials. The next step is larger scale production validation. If the unit economics work, this could be a meaningful shift for infrastructure emissions.

The key question is whether procurement rules in municipalities will actually favor biobased binders over conventional ones. Even if the tech works, public tenders often default to the cheapest option. Carbon pricing or embodied carbon requirements in public works contracts would help here.
