StageBio

StageBio is an international leader in GLP-compliant necropsy, histology, pathology, image analysis, and specimen archiving services. The company serves biopharmaceuticals, medical device firms, academic institutions, and contract research organizations by providing critical laboratory support from discovery through clinical development. Formed via the merger of several respected pathology labs—including HSRL and VPS—and expanded with acquisitions like TPL Path Labs in Germany in 2020. Backed by Ampersand Capital Partners since at least 2019. Employs over 25 board-certified veterinary pathologists and more than 100 laboratory staff across multiple US sites and one European facility. No internal drug pipeline or direct clinical results—their work underpins client R&D programs globally.
