Claros Raises $55M for PFAS Destruction Expansion

Claros Technologies has closed a $55 million Series B financing to expand commercialization of its ClarosTechUV PFAS destruction system and ClarosLabs analytical services. The round includes previously announced convertible note financing and will fund manufacturing, commercial deployments and hiring. Claros reported greater than 99.99% PFAS destruction in industrial process water and at least 99.99% destruction of targeted PFAS in groundwater remediation applications. The company plans to add deployments across North America, Europe and Asia for industrial manufacturers, remediation firms, utilities and government agencies.

Investors Back Commercial Expansion

Treehouse Family Capital LLC led the financing, joined by Daikin America, Inc., Veralto, Bush Foundation, Nord Asset Management and Saint Paul & Minnesota Foundation, alongside existing investors. Claros will use the capital to expand manufacturing capacity, product development, customer support and application development.

The company’s platform combines PFAS destruction technology with laboratory services for detection, quantification and exposure assessment. ClarosLabs is accredited to ISO/IEC 17025:2017, according to the release.

Michelle Bellanca, Chief Executive Officer and Co-Founder at Claros Technologies, said:

“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.”

Groundwater And Process Water Results

In December 2025, Claros and Daikin America completed an in-field PFAS destruction demonstration for industrial process water. Claros 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 PFAS compounds in a groundwater remediation application. The test used concentrate derived from about 1 million gallons, or 3.8 million liters, of groundwater.

Jack Cogen, Manager at Treehouse Family Capital LLC, said:

“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.”

Services For Compliance Needs

Claros expects demand for destruction and analytical services as PFAS requirements develop in Europe and the United States. The release cites broad PFAS restrictions under the European Union’s proposed REACH Regulation framework, along with expanding US drinking water standards, industrial discharge requirements and remediation programs.

The company was founded in 2018 and is based in Minneapolis, Minnesota. Its technology supports the continued use of PFAS in critical applications across industries including semiconductor manufacturing, aerospace, pharmaceuticals and healthcare. Its commercial expansion is aimed at industrial manufacturing, environmental remediation and regulatory compliance markets.
