Fungi funds: Visibuilt raises $3.8M for mycelium-based binders

July 13, 2026 |

In Denmark, biotech startup developing mycelium-based construction binders has raised €3.34 million (US$3.82 million) in seed funding to support scale-up and market development. Dubbed Visibuilt, the company was founded in 2022 by Line Kloster Pedersen and Oleksii Rebrov. They call the product visiBINDER. 

The round was co-led by EIFO and Unconventional Ventures.  Proptechfonden also participated, as did earlier investor EMDFonden. According to EU Startups, the company has raised €32 million to date. 

“Concrete and asphalt production are among the largest sources of CO₂ emissions globally. If we are to truly reduce emissions, it requires new solutions in heavy industries. Visibuilt has an approach that could become an important piece of that transition,” says Sara Sande, Managing Director, Partner and Head of Direct Thematic Venture at EIFO.
