Company Performance Metrics
Rui A. Sousa: CEO
Stemmatters is an integrated, science-driven CDMO focused on early clinical translation in advanced therapies and complex biologics. We support clients across the critical stages where risk is highest and resources are most constrained, providing: • Product and process development - designing, optimising and scaling manufacturing processes under
GMP principles, from feasibility through to clinical readiness. • Analytical method development and validation - building robust, regulator-ready analytical packages encompassing both compendial and non-compendial QC methods, to demonstrate product quality, consistency and control across product and process characterisation. • GMP manufacturing and clinical batch release - delivering GMP-compliant manufacturing, aseptic processing, fill & finish, storage and Qualified Person (QP) oversight for early clinical supply. Alongside these highly customised services, we also develop and manufacture high-quality raw and starting materials for the cell and gene therapy supply chain - an increasingly critical and often fragile component of advanced therapy development.
