KPMG vs Thoughtworks: overview

KPMG

KPMG was formed in 1987 through the merger of Peat Marwick International and Klynveld Main Goerdeler, and its member firms employ around 275,000 people. In December 2025 KPMG International announced ISO/IEC 42001 certification for its own AI management system, audited by Schellman; member firms in Australia, Spain, India, and the US had certified earlier. Its Trusted AI approach covers governance design, risk classification under the EU AI Act, controls testing, and assurance. For a CFO or chief risk officer who needs advice that an audit committee will accept, few firms have a larger bench. Auditor-independence rules can bar it from advising its own audit clients. Check that first.

Thoughtworks

Thoughtworks has around 10,000 people and has been based in Chicago since 1993. Apax took it private in a deal announced in August 2024, and a 2026 joint venture with New York advisory firm Teneo aims to strengthen its business advice. Its own advice is strongest on software and data foundations, and its public Technology Radar shows how it judges tools before you hire it.
