Finnish Startup Carbonaide Raises €3.7M To Scale CO₂-Cured Concrete Production

The financing, comprising equity and supporting financial instruments, will be used to scale operations and accelerate key strategic initiatives.

The funding round was led by Carbonaide’s existing investors Vantaan Energia, Redstone, and Ihantola Invest and supported by additional private investment firms and investors, including Zero Carbon Future Group, Product Ecology Holding B.V., Helkama Kiinteistöt and Ikorni Invest.

“With a lifetime focus on decarbonizing 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,” says Panu Pasanen, CEO of One Click LCA and investor through Zero Carbon Future Group.

The new funding will enable Carbonaide to expand internationally and accelerate R&D for new applications advancing the development of profitable carbon-negative concrete solutions.

“With this momentum, we are well-positioned to scale our technology, expand our CO₂ partner network and continue turning concrete factories into carbon sinks,” says Tapio Vehmas, CEO of Carbonaide. “There is clear demand in the construction industry for solutions that reduce emissions, showing that the industry is turning towards a low-carbon built environment.”

Carbonaide offers three core solutions: the CO₂ Curing System, providing end-to-end CO₂ curing for concrete producers, from design to integration; the Carbonaide Service Platform a cloud-based tool for managing CO₂ flow, carbon measurements and carbon credit issuance; and Carbonaide Care, offering full lifecycle support from setup to maintenance.

The newly raised capital will help expand customer acquisition through a strengthened global sales and marketing effort, further develop the Service Platform, and accelerate R&D beyond precast concrete.

The company plans to advance next-generation CO₂ curing for concrete elements with future applications expected for ready-mix and other concrete types.
