## About

Founded in 2018 and based in Finland, Carbonaide Oy is a spin-out of VTT Technical Research Centre of Finland and operates as a technology company that offers carbonization technology to precast concrete manufacturers. In March 2023, Carbonaide Oy raised EUR 1.8 million in seed funding co-led by Lakan Betoni and Vantaa Energy. As of March 2023, the company is led by its CEO Tapio Vehmas. In January 2026, Carbonaide Oy raised EUR 3.7 million in venture funding co-led by Vantaan Energia, Redstone, and Ihantola Invest, with participation from  Ikorni Invest, Zero Carbon Capital, Product Ecology Holding B.V., and Helkama Kiinteistöt.

Carbonaide Oy offers carbonization technology that uses industrial side streams and carbon dioxide (CO2) capture, utilization, and storage technology to manufacture carbon-negative concrete. The company's technology is fully compatible with Portland cement mixtures and aims to reduce cement consumption in daily production and decrease the carbon footprint of the products further by mineralizing CO2 into concrete.

The company will use the January 2026 funding to scale its concrete production process that stores carbon, strengthen its sales efforts, build its software for managing carbon flow and measurements, and expand research to apply its technology to more types of concrete.
