As the global economy grapples with worsening water scarcity and rising environmental scrutiny, one MIT-born startup founded by Anurag Bajpayee is scaling up its ambitions—and its footprint—by turning wastewater into opportunity.
Gradiant Corp., a Boston-based water technology company founded in 2013, is rapidly becoming a key player in the industrial water treatment market. The company has developed a suite of proprietary technologies that help manufacturers reduce freshwater use, recycle wastewater, and meet tightening environmental regulations. Backed by more than 280 patents and a growing roster of Fortune 500 clients, Gradiant is now plotting its next phase: a deeper push into Asia and Europe, and a potential public offering.
Gradiant’s rise comes at a time when multinational corporations face unprecedented pressure to cut their environmental footprints. Water, once taken for granted in industrial planning, is now a boardroom-level concern. Whether in chip fabrication or pharmaceuticals, clean water is critical—and increasingly scarce.
Gradiant’s origins lie in research conducted at the Massachusetts Institute of Technology. Anurag Bajpayee, who holds a Ph.D. in mechanical engineering from MIT, developed a novel desalination technique called Carrier Gas Extraction (CGE) during his doctoral studies. The technology mimics the natural rain cycle to purify water with lower energy inputs than traditional membrane-based systems.
Together with fellow researcher Prakash Govindan, Bajpayee co-founded Gradiant in 2013 to commercialize that innovation. The company’s early focus was on industrial water reuse, particularly for clients in water-stressed regions or with stringent discharge requirements.
Today, Gradiant offers a broader suite of solutions, including Selective Contaminant Extraction, advanced brine concentration, and digital monitoring platforms. Its end-to-end systems are now deployed in more than 2,500 facilities across 25 countries.
Bajpayee’s leadership at Gradiant reflects a blend of technical depth and business strategy. “Our mission is to enable industrial facilities to treat and reuse water sustainably, reducing their environmental footprint and operational costs,” he told MIT News earlier this year. He has consistently emphasized that Gradiant is not simply a technology licensor, but a full-scope solutions provider—designing, building, and in many cases operating systems on behalf of clients.
As climate challenges mount, Bajpayee believes companies will need to treat water not as a utility, but as a strategic resource. “The world is starting to act like it understands that,” he said in a 2024 industry panel discussion. “And we’re here to help industries move faster.”
Among its marquee clients are Micron Technology, Coca-Cola, Nestlé, and STMicroelectronics. Gradiant designs, builds, and operates water recycling plants on behalf of its customers—a full-stack approach that offers both flexibility and long-term performance guarantees.
“Gradiant is one of the few companies in the water space that’s figured out how to scale technology profitably,” said one investor familiar with the firm. “They’re solving a problem that’s only getting worse.”
While Gradiant’s headquarters remain in Boston, its operational strategy is increasingly international. With a historical presence in Asia, the company has also expanded its footprint in the Middle East, Southeast Asia, and Europe—regions facing severe water stress and tightening environmental policies.
In 2023, Gradiant was named “Water Company of the Year” by Global Water Intelligence. The following year, it was awarded “Water Technology Idol,” further solidifying its reputation as a leader in innovation.
