EY Law Firm

What EY Law Firm does

EY Société d'Avocats is the French law firm entity of the global EY professional services organization, providing integrated legal and tax advisory services to enterprises, startups, and high net worth individuals. Founded in 2003 and headquartered at Tour First in Paris La Défense, the firm operates from 11 offices across France and leverages EY's international network spanning more than 150 countries to serve multinational clients on cross-border matters. Its primary customer base consists of large enterprises and multinational corporations requiring support for M&A, regulatory compliance, tax optimization, and corporate governance, with secondary segments covering startups through the EY Ventury Avocats sub-brand, high net worth individuals, and digital asset platforms.

The firm delivers services across three core practice areas: Fiscalité (Tax Services) covering tax strategy, compliance, disputes, and international trade tax; Droit des affaires (Business Law) covering M&A, real estate, intellectual property, data protection, energy, structured finance, and environmental law; and Capital humain (Human Capital) covering labor law, international mobility, compensation policy, and social aspects of M&A. Its proprietary technology includes the eTaxLawServices digital platform, which provides rapid online resolution of practical tax and legal questions, plus a dedicated legal function digital transformation service. AI capabilities are primarily inherited from the parent EY organization, including the EY.ai platform launched following a US$1.4 billion investment and an NVIDIA AI partnership, with conversational AI applications used within the French practice in healthcare advisory contexts.

Revenue is generated through professional services fees structured as hourly rates, fixed fees, or project-based arrangements, with no public pricing disclosed. The go-to-market motion relies on partner-led direct enterprise engagement across the firm's national office network, supported by international referrals through the EY global network. Marketing channels include webcasts, white papers, press releases, professional training programs, and the long-running annual "Best Young Tax Specialist" trophy co-organized with Aix-Marseille University and Editions Francis Lefebvre since 1995. Recent operational signals include a new Managing Partner (Matthieu Autret, January 2026), a lateral partner hire (Yordan Nenkov, January 2025), a deal with Servier (September 2025), and a Crypto Compliance & Legal Roundtable co-organized with Solidus Labs (May 2026).
