Mineral Minds is a market-neutral technology platform that digitizes material flow management across the German construction and waste management sectors. By connecting construction sites with a nationwide network of 4,500+ supply and disposal partners, the platform enables companies to find economically and ecologically optimal routes for excavated soil, aggregates, and mineral waste in real time. Founded in Stuttgart in 2019 with a "Stoffstrom as a Service" model, Mineral Minds acts purely as an independent matchmaker — it does not buy, sell, or trade materials or data. The platform supports the full lifecycle from cost calculation through operational execution to CO2 and waste reporting, helping close material loops and drive circularity at scale across the built environment.
