Visibuilt

Visibuilt, a Danish biotech firm established in early 2023, is targeting the global road construction industry with a bio-based alternative to bitumen, the fossil-fuel-derived binder in asphalt. The company was founded by CEO Line Kloster Pedersen, a biotechnologist and serial entrepreneur who previously co-founded a fungi company in the food industry. Her inspiration came from observing how mycelium, the root-like structure of fungi, naturally binds soil together, leading to the concept of using it as a binder for asphalt.

The company's core product is visiBIT, a fermentation-based binder developed from mycelium. This technology aims to replace bitumen, which constitutes about 5% of asphalt but is a major contributor to the industry's carbon footprint and energy consumption due to the high temperatures required for production. By contrast, visiBIT is produced through an energy-efficient fermentation process and can be applied at room temperature, which could reduce CO2 emissions from asphalt production by an estimated 80%. Furthermore, the process utilizes waste materials, positioning it as a circular economy solution. Visibuilt's business model is B2B, focusing on supplying visiBIT to asphalt producers. A key selling point is that the technology is compatible with existing asphalt infrastructure, eliminating the need for clients to invest in new plants or factories.

Since its founding, Visibuilt has achieved significant milestones. The company secured a total of €4.4 million in funding, including a €1.1 million pre-seed round in early 2025 led by EMDFonden and a consortium of experienced biotech investors. A major technical achievement was the successful testing of visiBIT at the Fehmarnbelt Tunnel construction site, one of Northern Europe's largest infrastructure projects. The company has established its headquarters and labs at the Danish Technological Institute and has grown its team to over a dozen employees. Collaborations with partners across the asphalt value chain, such as Munck Asfalt, have been central to its development and testing processes. The funding is being used to expand the team, advance R&D, and conduct more outdoor pilot tests, with the initial focus on applications like bike paths before scaling to broader road construction.
