Vateris, the company formerly known as Concrete4Change, today announces the successful close of its latest funding round, bringing total capital raised to date to $10 million USD.
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.
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.
“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. 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.”
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.
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.
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.
“What makes Vateris powerful is not just decarbonisation — it's economics. We are building a platform that converts CO₂ into performance-enhancing minerals that improve margins, strengthen end-products, and reduce embodied carbon simultaneously. We are not participating in this transition — we intend to lead it.”
