Company Description
Founded in 2018 and based in the United States in Minneapolis, Minnesota, Claros Technologies is a global leader in PFAS mitigation, with two core divisions. The ClarosTech™ division focuses exclusively on the permanent destruction of PFAS, offering affordable, high-flow, scalable, and field-ready systems that destroy long, short, and ultra-short chain PFAS compounds. ClarosLabs™, the company's ISO/IEC 17025:2017 accredited analytical division, is a leading commercial laboratory dedicated solely to PFAS detection, quantification, and exposure assessment.
We are a diverse team of scientists, engineers, business builders, and impact-driven leaders dedicated to solving critical environmental problems. In 2026, Claros closed a $55 million financing round, positioning us to fulfill commercial adoption and expand globally. If you're a mission-driven and highly motivated individual looking to solve problems without creating new ones, join our team in accomplishing our mission to take the ‘forever’ out of “forever chemicals” and destroy PFAS for good.
