# TrustBridge Compliance

> Specialist advisory practice for validating AI in GxP environments, CSV to CSA transformation, and digital quality in pharmaceutical manufacturing. Led by Sachin Bhandari: 25+ years leading quality IT and digitalization in global pharma, author of "Validating AI in GxP: A Practitioner's Guide", 300+ regulatory inspections supported, and AI validated in live GxP quality systems then taken through Health Authority inspections with zero compliance observations.

TrustBridge Compliance helps mid-size pharma, biotech and CDMO organisations answer one question: when an inspector asks how you validated your AI, can you show a defensible answer? The practice covers AI governance aligned to the draft EU GMP Annex 22, the transition from Computer System Validation (CSV) to Computer Software Assurance (CSA) under FDA guidance and GAMP 5 second edition, digital validation, GxP cloud qualification, and quality management system modernisation.
