Schlesinger Group

Schlesinger Group is an established market research and data collection company that now operates under the Sago brand. The business provides qualitative and quantitative research services, participant recruitment, panels, in-person research facilities, and technology-enabled insight solutions for corporate clients across multiple industries. It has historically included healthcare and clinical research capabilities, but it is not a drug-development biotech or pharmaceutical company and does not have a therapeutic pipeline. The company was founded in 1966, expanded through acquisitions, and is backed by private equity owner Gauge Capital. For biotech and healthcare customers, its relevance is as a research services and healthcare insights vendor rather than a therapeutics developer.
