Vateris secures strategic investment from Holcim and Kiilto

The round includes new strategic investment from Holcim MaQer Ventures, the venture capital arm of the world’s leading cement and concrete producer, and Kiilto Ventures, alongside continued support from existing investors.

The raise marks a pivotal moment in the company’s evolution: the transition from pilot validation to industrial scale-up, and from a breakthrough start-up to a strategically backed materials platform.

Alongside this investment, Vateris has significantly strengthened its commercial team with senior talent from the global building materials and fertiliser industries – executives who have successfully industrialised and commercialised breakthrough technologies at scale. This expansion marks a deliberate shift from technology validation to industrial execution.

Global strategic investors join cap table

The round introduces two new major industrial investors:

• Holcim MaQer Ventures, the venture arm of Holcim, the world’s leading cement and concrete producer
• Kiilto Ventures, the investment arm of Kiilto, a leading European construction chemicals company headquartered in Finland.

They join existing strategic and industry-aligned investors Goldbeck and Zacua Ventures, significantly strengthening Vateris’ position within global construction value chains.

Holcim’s participation provides strong validation of Vateris’ ability to integrate into mainstream cement and concrete production at global scale. Kiilto brings complementary expertise in performance materials and route-to-market across European construction chemicals markets.

Together with Goldbeck and Zacua Ventures, Vateris now has a shareholder base deeply aligned with industrial deployment – signalling a clear shift from early-stage validation to strategic scale-up.

From Concrete4Change to Vateris

The company is also announcing a change of name from Concrete4Change to Vateris. It is part of a broader rebrand which reflects the maturation of the company’s technology and ambition. What began as an innovative CO₂ mineralisation concept has evolved into a precision carbon-to-materials platform built around the engineering of vaterite, a carbon-negative high-performance polymorph of calcium carbonate. Added to concrete, it delivers higher performance, lower cost and reduced carbon intensity.

Vateris’ proprietary process converts industrial flue gas CO₂ into GypCarb^™, a high-performance vaterite-based mineral additive for cement and concrete, while co-producing high-purity, high value SOP mineral fertiliser. The result is permanent mineral carbon storage embedded directly into best-in-class mineral products.

GypCarbTM is designed as a drop-in solution delivering superior performance in cementitious systems – simultaneously delivering better economics and carbon reduction, requiring no redesign of cement or concrete production infrastructure or changes to regulatory standards – all critical factors for rapid market adoption.

Having successfully commissioned its pilot plant, Vateris is now scaling its process towards realising a first-of-a-kind commercial plant, co-located on a major industrial partner site, directly off-taking flue gas CO2 to produce Vateris’ GypCarb and SOP fertiliser products. Vateris’ approach reframes CO2 from a compliance liability into a performance-enhancing input. This approach creates a new industrial equation: carbon becomes a feedstock that enables best-in-class performance while delivering permanent mineral storage.

Prof. Sid Pourfalah, Founder & CEO of Vateris, said: “Vateris is not a solely single-product company – we are building a carbon-to-materials platform. Our core breakthrough is the ability to precisely engineer mineral phases from industrial CO2 streams and tune them for performance, with our GypCarb product for cement and concrete being the core novelty. What we have developed around this is a scalable process pathway that allows us to transform waste carbon into best-in-class materials.

That platform unlocks a new industrial model – one where carbon becomes a feedstock for high-performance, lower-cost, lower-carbon materials across construction, chemicals, and fertilisers.

The science has reached maturity and the economics are compelling. With strategic industrial investors now aligned with our vision, we are moving decisively from validation to scale.
