PwC vs EY: overview
PwC
PwC's network took its current form through a 1998 merger and today employs roughly 370,000 people. Its Responsible AI practice, led in Germany by partner Hendrik Reese, helps clients inventory and classify AI systems, run gap analyses, and plan compliance across the EU AI Act, DORA, GDPR, and NIS2. Standards work covers ISO/IEC 42001 and the NIST AI Risk Management Framework. PwC also tests client chatbots for accuracy and bias, an early step toward formal AI assurance. Like the other Big Four, it sells delivery as well as advice.
EY
EY was formed by the 1989 merger of Ernst & Whinney and Arthur Young and employs about 400,000 people. Its advisory teams cover responsible AI, AI risk, and compliance programs, and its technology risk leaders have spoken publicly about how far real AI assurance still has to go. That candor is useful for buyers who want an honest view of what can be certified today. Like the rest of the Big Four, it sells implementation as well.
