What Exponens does

Exponens is a French multidisciplinary professional services group providing accounting, statutory audit, financial consulting, transformation advisory, compliance and internal control, risk and insurance, wealth management, employment/HR, legal/tax, and corporate social responsibility (CSR) advisory services. The firm operates as a SAS (Société par Actions Simplifiée) under the legal name EXPONENS Conseil & Expertise, founded in 1988 and headquartered at 201-203 rue de Bercy, 75012 Paris, with 9 offices across the Paris Île-de-France region and an international delivery network through BKR International and the Eurus Alliance.

The group serves roughly 7,800 clients worldwide across 11 dedicated industry verticals — including associations and foundations, banking and insurance, real estate and investment funds (with OPCIs specialization), hospitality and Michelin-starred restaurants, luxury, industry, healthcare, energy/cleantech, notaries, public sector, and digital/startup companies — delivering services through 33-36 specialist partners and approximately 500 expert collaborators. Notable sector specialization includes OPCI (real estate investment fund) accounting led by Sophie Breton since 2008, hospitality accounting for Michelin-starred restaurants under Emmanuel Maugé, luxury and Italian-desk international work under David Dana, and CSE (works council) expertise reinforced by the 2022 acquisition of Volentis and the 2024 merger with Groupe Legrand.

Revenue is generated through professional service fees billed on quote-based engagement terms, with no public pricing list and no proprietary software platform. The go-to-market is enterprise field sales, delivered via dedicated partners managing key accounts through direct office visits rather than intermediated channels. Disclosed revenue is €60M, described as 'in constant progression,' and the firm has pursued continuous inorganic expansion — subsidiaries include Exponens Avocats (legal), Exponens Croissance (growth advisory), Exponens Retraite (retirement planning), Exponens Assurances (insurance), Exponens Formations (training), Volentis (HR/payroll), Groupe Legrand (CSE), and ARPEGE (audit and accounting). Leadership is held by President Jean-Pierre Bourgin and CEO Anne Barraud, with COO Thierry Legrand overseeing operations, supported by an Executive Committee and an active Quality & Ethics Committee structure.
