Visibuilt, founded in 2023, develops visiBINDER, a fermentation-produced mycelium binder designed as an alternative to fossil-derived bitumen and cement for paving and infrastructure. The company says its process can bind aggregate at near-room temperature, potentially reducing energy use and manufacturing emissions versus conventional asphalt production. Visibuilt has moved beyond the lab with industrial testing partnerships with NCC and Munck Asfalt, a strategic development partnership with Denmark’s leading concrete paver manufacturer IBF to create visiPAVER, and trials with Copenhagen Municipality. The startup is headquartered at the Alfa Laval Innovation House near Copenhagen and runs labs and pilot facilities at the Danish Technological Institute, employing roughly 18 people. Its near-term plans, supported by the €3.34 million seed raise, are to scale production capacity, validate the solution at larger scale, and expand its technical and commercial team. Visibuilt still faces regulatory hurdles, including the lack of an EU standard for non-oil asphalt binders and the need for CE marking before broader road deployment.

Founded in Copenhagen in 2019, Oktogrid builds a patented magnetic-adhesion sensor and an AI-driven software platform to monitor transformer condition, predict faults, recommend maintenance, optimise capacity and estimate remaining life. Its sensor installs in under 15 minutes and collects acoustic and operational signatures fed into the company’s analytics platform. The company reports more than 45 customers, including 12 utilities added in the last 24 months, deployments across three continents, monitoring of over 1 GW of critical infrastructure and over 5 million hours of transformer data in production. Oktogrid says its technology has detected 26 early faults, freed more than 8,600 hours of technical work, unlocked 198 MVA of additional capacity and extended monitored asset life by an average of 15 years. With the new €4 million round, Oktogrid intends to scale internationally, expand its fleet-management product capabilities and enter low-voltage distribution grid markets to broaden its addressable market.
