Gradiant, a Boston-based industrial water technology company, has raised a Series E funding round that values the company at $2 billion. The investment marks a major milestone for the firm as it accelerates expansion across AI infrastructure, semiconductor manufacturing, and large-scale industrial water systems. The funding round was led by Safar Partners and Hostplus Superannuation Fund, with participation from ClearVision Ventures and other global investors.
The company stated that the new capital will be used to support strategic acquisitions, strengthen research and development, and scale global operations. A key focus is preparing the business for future public listing while meeting rapidly growing demand from industries that rely heavily on advanced water treatment, particularly data centers and chip manufacturing facilities.
Gradiant has seen strong growth driven by the rapid expansion of artificial intelligence infrastructure, where water usage has become a critical constraint for cooling and operational efficiency. The company provides end-to-end water treatment and recycling solutions that help major industrial clients reduce consumption, reuse wastewater, and improve sustainability in resource-intensive sectors.
Alongside AI-driven demand, semiconductor manufacturing remains a major growth area for Gradiant, as chip fabrication requires ultra-pure water systems and highly controlled treatment processes. The company’s technologies are increasingly positioned as essential infrastructure for advanced manufacturing ecosystems, especially as global chip production expands.
The Series E financing reflects rising investor confidence in companies supporting the AI and industrial infrastructure ecosystem, where water, energy, and cooling systems are becoming as critical as compute hardware itself. With this latest round, Gradiant is positioned to further scale its global footprint and strengthen its role in enabling sustainable growth for AI and semiconductor industries.
