What SePRO Corporation does

SePRO Corporation, founded in 1994 and headquartered in Carmel, Indiana, is a privately held environmental solutions company that develops and commercializes science-based plant protection and water resource management products across six verticals: Pro Aquatics, Agriculture, Golf, Landscape, Ornamental, and DIY Aquatics. The company's technology foundation rests on a 410-acre SePRO Research & Technology Campus (SRTC) in Whitakers, North Carolina, where it conducts water quality diagnostics, algae research, and product development across herbicides, plant growth regulators, fungicides, insecticides, and algaecides. Flagship intellectual property includes ProcellaCOR, an EPA Reduced Risk aquatic herbicide using a novel mechanism of action requiring 40x-100x less active ingredient than conventional treatments, alongside proprietary PGR brands (Cutless, Musketeer, Legacy, Edgeless, Profile 2SC), the Prescription Dose Unit (PDU) dosing system, and the SeSCRIPT/FasTEST/GenTEST laboratory services delivered through the SYNC digital platform. April 2026 acquisitions of Earth Science Laboratories, Resolve Hydro, Arietta.ai, and Green Eyes LLC extend the portfolio into industrial water treatment, digital diagnostics, and environmental monitoring.

The business model is built on one-time product sales through a multi-channel go-to-market: direct sales supported by regional Technical Specialists, a PRO Certified ProcellaCOR Specialist applicator network that is the exclusive channel authorized to apply flagship aquatic products, agricultural and turf distributors serving golf and landscape professionals, and a DIY Aquatics e-commerce storefront. Auxiliary revenue derives from professional laboratory and diagnostic services (water quality prescription, rapid water analysis, plant population assessment) accessed through the SRTC campus and SYNC platform. Distribution is geographically U.S.-centric with limited Canadian operations. In July 2024, Stanley Capital Partners acquired a majority stake with Goldman Sachs Alternatives as a minority co-investor to underwrite continued technological and operational growth in water management solutions.
