BOSTON-- May 18, 2023 -- Gradiant, a global end-to-end solutions provider of advanced water and wastewater treatment, today announced it has raised $225 million in its first close of Series D financing. The round was led by BoltRock Holdings and Centaurus Capital, bringing Gradiant’s total funding to date to over $400 million and its valuation to $1 billion.

Gradiant is one of the fastest-growing companies in the water industry achieving over 100% YOY top-line growth for four consecutive years. The company will use the new financing to continue its expansion into strategic markets to make Gradiant the preferred water partner of the world’s essential industries.

Gradiant designs, builds, and operates end-to-end water treatment solutions for the world’s most important industries, including semiconductors, pharmaceuticals, food & beverage, lithium and critical minerals, and renewable energy. The company’s proprietary technologies and integrated digital solutions reduce water usage, reclaim valuable resources, and renew wastewater into freshwater for some of the world’s largest companies, including Micron, TSMC, GSK, Pfizer, SLB, Rio Tinto, AB InBev, and Coca-Cola.

“This investment is a testament to Gradiant’s proven track record of rapidly inventing and commercializing water technologies to make a real difference in the economic and environmental footprints of our industrial customers,” said Anurag Bajpayee, Co-Founder and CEO of Gradiant. “BoltRock and Centaurus share our vision and bring smart, long-term capital that will help Gradiant grow into the world’s most impactful water company.”
