Claros Technologies has raised $55 million in Series B financing to accelerate the global commercialization of its ClarosTechUV system for permanently destroying per- and polyfluoroalkyl substances, commonly known as PFAS or forever chemicals. The total includes the company’s previously announced convertible note financing.
The funding will support expanded manufacturing capacity, additional commercial deployments across North America, Europe and Asia, continued product development and the growth of ClarosLabs, the company’s PFAS-focused analytical laboratory. Claros also plans to hire additional engineering and commercial personnel and invest in customer support and application development.
The round was led by Treehouse Family Capital, with participation from Daikin America, Veralto, Bush Foundation, Nord Asset Management, Saint Paul & Minnesota Foundation and existing investors. The financing brings together financial and strategic backers from industrial, environmental and technology markets.
PFAS are a large class of synthetic chemicals valued for their resistance to heat, oil, water and chemical degradation. They are used in applications including semiconductor manufacturing, aerospace, pharmaceuticals and healthcare, but their persistence has also resulted in widespread contamination concerns.
ClarosTechUV is designed to destroy PFAS rather than merely remove the chemicals from water and transfer them into another waste stream. Claros combines the destruction technology with laboratory services that detect, quantify, and document PFAS concentrations for industrial customers, remediation companies, utilities, and government agencies.
In December 2025, Claros and Daikin America completed a large in-field demonstration involving industrial process water and reported greater than 99.99% destruction across long-, short- and ultra-short-chain PFAS compounds. In April 2026, the company reported at least 99.99% destruction of targeted compounds in concentrate produced from approximately one million gallons of groundwater.
The financing arrives as regulators in the United States and Europe increase drinking water standards, remediation requirements, industrial discharge controls and proposed restrictions involving PFAS. These changes are increasing demand for technologies capable of permanently destroying the chemicals while generating the analytical documentation required for compliance.
KEY QUOTES:
“Over the past year, Claros has crossed the threshold from breakthrough technology to successful commercial reality. Our work with major industrial manufacturers has demonstrated that permanent destruction of all targeted PFAS species can operate reliably, efficiently and cost-effectively at commercial scale, while our recent groundwater remediation results have shown that the same technology performs exceptionally well across complex environmental applications.”
“Coupled with the rapid evolution and implementation of PFAS regulations around the world, these milestones have fundamentally expanded our opportunity. This financing gives us the resources to accelerate commercial deployments globally, continue advancing our technology, and help customers address one of the world’s most significant environmental challenges.”
Michelle Bellanca, Co-Founder and CEO of Claros Technologies
“The most exciting technology companies eventually reach an inflection point where the question is no longer whether the technology works, but how quickly it can be deployed at scale. We believe Claros has reached that point.”
“Claros has demonstrated that its technology is effective under real-world commercial conditions. Claros has built an integrated platform that combines PFAS destruction with analytical services and is scaling commercially at exactly the right time. With regulatory momentum accelerating around the world, we see an opportunity to help build one of the defining environmental technology companies of the next decade and beyond.”
