About

Claros Technologies develops proprietary PFAS destruction, detection, and analytical technologies that permanently eliminate per- and polyfluoroalkyl substances (forever chemicals) from water and industrial processes. The company operates two core product lines: ClarosTechUV, a PFAS destruction system that destroys 99.99% of long, short, and ultra-short chain PFAS (C2 to C14) at the source, adaptable to both batch and high-flow configurations with a small footprint and cost-effective scaling; and ClarosLabs, an ISO/IEC 17025 accredited laboratory offering superior PFAS analytical capabilities ranging from combustion ion chromatography (CIC) for total organofluorine to high-resolution mass spectrometry. The company also provides PFAS regulatory compliance services, including Attorney-Client Privileged Analytical Assessment (ACPAA) to help manufacturers assess potential PFAS liabilities in a privileged legal setting, and develops advanced materials with antiviral, antifungal, UV-resistant, odor-resistant, and moisture-wicking properties. Claros has treated over 3.8 million liters of water and serves both private and public sector clients across municipal water treatment, manufacturing, and environmental remediation. Founded in 2015 and headquartered in Saint Paul, Minnesota, Claros Technologies has raised approximately $104.6 million in a Series B round backed by 3x5 Partners, Discovery Capital, TechFounders, Ecosystem Integrity Fund, American Century Investments, the United States Department of Agriculture, Capita3, University of Minnesota, F. R. Bigelow Foundation, and Groundswell Ventures.
