crownbio

Crown Bioscience (CrownBio) is a global contract research organization (CRO) specializing in translational oncology and immuno-oncology drug discovery. It provides preclinical and translational services to biotech and pharmaceutical companies, including in vitro drug screening (cell lines, organoids, panels), in vivo studies (PDX, CDX, syngeneic and humanized models), DMPK/toxicology, preclinical imaging, and biomarker analysis spanning genomics (NGS, single-cell sequencing), proteomics, spatial biology, and flow cytometry. CrownBio also operates public web-browsable cancer-model databases — a PDX Model Database (2,500+ models), an Organoid Models Database (600+ models), an IO Murine Models Database, and a Cell Line / CDX Database — searchable through a Multi-Model Search interface. There is no public developer API or programmatic data access; the databases are web interfaces. This profile was surfaced as a portfolio company of Qiming Venture Partners and enriched by the API Evangelist pipeline.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
