Skreenhouse Ventures by SigmaRoc Leads Investment in Koncrete
to Advance Digital and Low-Carbon Logistics

Skreenhouse Ventures ('Skreenhouse'), the innovation and investment arm of SigmaRoc focused on advancing technology across the raw materials and construction value chains, has led a €1 million seed funding round in Koncrete, a French construction technology startup. The investment supports efforts to digitise procurement and logistics in the building materials sector and reflects Skreenhouse's focus on scalable, data-driven infrastructure solution.

The Investment

Founded in 2023, Koncrete enables construction professionals to obtain real-time quotes, compare supplier pricing, and coordinate logistics through a unified digital platform. In its first year of operation, the startup has referenced over 2,800 suppliers, delivered to more than 10,000 construction sites, and facilitated the transport of hundreds of thousands of tonnes of materials.

The funding will be used to support Koncrete's continued growth in France, with a focus on improving operational efficiency and data-driven logistics.

Focus on Operational Efficiency and Emissions Reduction

Koncrete is also advancing a set of environmental initiatives aimed at reducing the carbon impact of building materials logistics. These include:

·      Integrating recycled materials from demolition into supply chains

·      Minimising empty return trips through freight optimisation

·      Reducing average transport distances (currently 26 km, below the 32 km national average)

Fons Vermorken, Group ExCo Member - Innovate, SigmaRoc, commented:

"Koncrete is building essential infrastructure for the future of building materials logistics-efficient, data-driven, and lower carbon. We are pleased to support the team in scaling a solution that aligns with our commitment to industrial innovation and sustainability."
