GRANT THORNTON France

What GRANT THORNTON France does

Grant Thornton France is a member firm of Grant Thornton International Ltd, headquartered in Neuilly-sur-Seine and operating as an integrated audit, advisory, and consulting group in France since 1964. The firm employs approximately 1,600 people across 27 offices, serving four primary client segments — large groups (Grands Groupes), mid-sized companies (ETI), family businesses (Entreprises Familiales), and the public sector — with additional specializations in private equity and financial services (banking, asset management, insurance). Its offering is organized into nine core service lines: Audit, Audit & Assurance Solutions, Deal Advisory, Conseil Opérationnel, Expertise Conseil, Conseil Juridique et Fiscal, Transformation Durable, International Business Advisory, and Financial Services, supplemented by Business Process Outsourcing (BPO). The firm combines regulated statutory audit mandates (Commissariat aux Comptes) with deal advisory, operational consulting, legal services (via the Akilys brand), ESG/CSRD advisory, and international cross-border work delivered through country desks and the broader 150+ country Grant Thornton network.

Underlying the service portfolio is a portfolio of technology-enabled tools: Pulse AI (a securely deployed generative AI solution for internal and client use), the Flow business management platform, SCube (accounting consolidation), Data Privacy SandBox (GDPR testing), Génédoc (document automation, partnered with Aezan), and the MyOffice client portal. The firm has invested in Smart Automation and Data Analytics capabilities embedded in its Operational Consulting practice, and applies anomaly detection within its Forensic and Compliance (Sapin 2) engagements. These are features layered onto a professional services delivery model rather than a standalone software product business.

Revenue is generated through quote-based professional services fees determined by scope, complexity, regulatory requirements, and client size, with multi-year contract cadence typical for audit and large advisory engagements. Go-to-market is partner-led and direct, distributed across 27 French offices, supplemented by industry events, webinars, thought leadership publications (e.g., "La Lettre des Décideurs", "Leaders and Shakers"), and — for public-sector clients — the UGAP procurement framework. Pricing is not publicly disclosed. Since 2024 the firm has pursued an aggressive growth strategy, executing the Finexsi statutory audit acquisition (2024), the Akilys law firm merger (May 2025), a cross-border merger with Grant Thornton US, Spain and Belgium backed by private equity investor New Mountain Capital (Sept 2025), and the DPO Consulting acquisition (March 2026).
