Green concrete startup Carbonaide has raised €3.7 million to transform the concrete industest through carbon dioxide curing and permanent CO₂ storage. Carbonaide’s technology has been in commercial production since 2024.
In 2025, Carbonaide entered into agreements with two Finnish companies, concrete producer Lakan Betoni and concrete element manufacturer Lipa-Betoni, to install its technology in their factories. Production with the Carbonaide systems launchs in both facilities in early 2026.
In January 2026, Carbonaide also sold the first certified carbon credits created through its mineralisation.
The round was 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.
“With a lifetime focus on decarbonising construction, I am very excited by Carbonaide’s potential. Now that the technology is ready to scale, we are thrilled to support the growth of the company and also to partner with Carbonaide to supply carbon data for low-carbon products,” declares Panu Pasanen, CEO of One Click LCA and investor through Zero Carbon Future Group.
The new funding will support Carbonaide’s international expansion and boost R&D activity towards new applications, building carbon-negative concrete profitable.
The funding will be utilized to drive progress across three core areas:
- Expansion of customer acquisition by strengthening the company’s global sales organisation and marketing efforts.
- Further development of the Carbonaide Service Platform – a cloud-based software platform for managing CO₂ flow, carbon measurements and carbon credit issuance that will serve as the backbone of our solution.
- Accelerated R&D beyond precast concrete – quick-tracking the development of Carbonaide’s roadmap extension, starting with next-generation carbon dioxide curing for concrete element production. This will pave the way for applications in ready-mix and other concrete types.
“With this momentum, we are well-positioned to scale our technology, expand our CO₂ partner network, and continue turning concrete factories into carbon sinks,” declares Tapio Vehmas, CEO of Carbonaide.
“There is clear demand in the construction industest for solutions that reduce emissions, displaying that the industest is turning towards a low-carbon built environment.”
