53Biologics is a Spanish contract development and manufacturing organization (CDMO) based in Valladolid specializing in biologics production, from plasmid DNA and mRNA components to recombinant proteins, offering cell line development, analytical and process development, and GMP manufacturing from preclinical through commercial stages. Founded in 2017 as a biopharmaceutical subsidiary of the BDi Biotechnology Group, it has raised venture funding from Inveready and GAEA Inversión and in 2026 took on a majority-stake investment from European private equity firm Ren Life Sciences to expand its GMP biomanufacturing capacity.
