Carbonaide Closes New Investment Round to Accelerate Growth

Carbonaide, turning building materials from a large emission source into a carbon sink with the help of technology, led by Tapio Vehmas, Jonne Hirvonen, Matias Impivaara, and others, has raised €3.7 million on its latest funding round, led by Carbonaide’s existing owners, Vantaan Energia, Redstone, and Ihantola Invest, and joined by a group of private investment companies and investors, including Zero Carbon Future Group, Product Ecology Holding B.V., Helkama Kiinteistöt, and Ikorni Invest.

The investment marks a major milestone in transforming the concrete industry through carbon dioxide curing and permanent CO₂ storage, enabling scaled operations and accelerated strategic initiatives.

Carbonaide’s scalable decarbonization technology is positioned for growth, with support to expand operations and supply carbon data for low-carbon construction products, according to investor Panu Pasanen of One Click LCA.

The funding will support international expansion, increased R&D, and progress toward profitable carbon-negative concrete. Key priorities include strengthening global sales and marketing, advancing the Carbonaide Service Platform for CO₂ management and carbon credit issuance, and accelerating R&D beyond precast concrete, including next-generation CO₂ curing for broader concrete applications.

Carbonaide is positioned to scale its technology, expand its CO₂ partner network, and convert concrete factories into carbon sinks, with growing demand from the construction industry for low-emission solutions and a shift toward a low-carbon built environment.

Carbonaide’s technology has been commercially deployed since 2024, with agreements signed in 2025 to install systems at Lakan Betoni and Lipa-Betoni, with production starting in early 2026. In January 2026, the company sold its first certified carbon credits generated through mineralization.
