Grant Thornton France Acquires Data Privacy Firm

Grant Thornton France has significantly expanded its advisory capabilities by acquiring DPO Consulting, a specialized firm dedicated to personal data protection and GDPR adherence. This strategic move marks the first acquisition for Grant Thornton France since its integration into the Grant Thornton Advisors structure, which is overseen by a consortium led by New Mountain Capital, in September 2025. The integration of DPO Consulting's 43-strong team of data protection specialists is set to enhance Grant Thornton's offerings in data governance, privacy compliance, and technology regulation advisory.

The acquisition addresses a rapidly escalating demand for expert guidance on data privacy and emerging AI governance frameworks across the European market. As regulatory obligations intensify under frameworks like the EU's General Data Protection Regulation (GDPR), the forthcoming EU AI Act, and the NIS2 Directive for cybersecurity, businesses are increasingly seeking specialized consulting services to navigate this complex environment. The market for such advisory services is experiencing robust growth, driven by the critical need for compliance and risk mitigation.

DPO Consulting, established in 2015 by Marine Brogli, brings a wealth of experience advising over 800 clients. Their expertise spans a range of critical regulations, including the EU GDPR, Singapore's PDPA, and Switzerland's nLPD, alongside proactive engagement with new rules governing artificial intelligence and cybersecurity. Following the transaction, Marine Brogli will join Grant Thornton as an Associate, contributing her deep knowledge to the expanded advisory practice.

This strategic integration is particularly timely given the evolving digital economy. The global data privacy management market is projected to reach significant figures in the coming years, underscoring the strategic importance of this acquisition for Grant Thornton France. By incorporating DPO Consulting's specialized talent and client base, the firm solidifies its position as a key player in the burgeoning field of digital regulation and data protection advisory services.

The move by Grant Thornton France, a firm already recognized for its audit, tax, advisory, and outsourcing services to mid-market enterprises, signals a clear commitment to deepening its expertise in areas critical to modern business operations. The addition of DPO Consulting's specialized knowledge is expected to create significant synergies, enabling Grant Thornton to offer more comprehensive solutions to its clients facing complex data protection challenges.

This transaction was facilitated with legal counsel provided to Grant Thornton by Osborne Clarke. The successful integration is anticipated to provide a competitive edge for Grant Thornton France in a market where regulatory compliance and data security are paramount concerns for businesses of all sizes.
