PwC vs ML6: 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.

ML6

ML6 has been building AI in Ghent since 2013 and employs 140+ people in Belgium, Germany, and the Netherlands. Its strategy work covers ambition-setting workshops, use-case discovery, and EU AI Act questions, and OpenAI named it a services partner in June 2025. Most clients go on to build with ML6, so the advice is grounded in engineering reality but not neutral about who builds.
