ORSEU

What ORSEU does

ORSEU, operating under the legal entity GROUPE ORSEU ETHIX, is a French professional services firm founded in 1992 that supports employee representative bodies (CSE — Comité Social et Économique) in French enterprises. Through its core brand ORSEU ETHIX, the firm delivers expert consulting mandated by CSE votes: economic and financial analysis of the employer, support during salary/bonus negotiations (NAO), assessment of restructuring plans (PSE), collective redundancy agreements (RCC), workplace health and safety expertise (SSCT), and handling of urgent situations such as harassment or economic alerts. The firm combines accounting and workplace-health expertise in a single multidisciplinary team, a positioning that allows a CSE to engage one contact point for both financial and SSCT mandates.

The group has expanded into adjacent services via three additional sub-brands. ORSEU CONCOURS sells EU civil service exam preparation courses (EPSO AD5) directly to individual candidates, with course pricing ranging from €65 to €625 and documented user outcomes of a 40% higher pass rate and a 9-point average score improvement. ORSEU RECHERCHES & ÉTUDES is a research and studies arm, and MYCSE is a digital platform providing tools and resources to CSE representatives. Distribution is direct: enterprise mandates follow a structured three-step engagement (initial contact, CSE designation vote, expert report and ongoing accompaniment), while Concours sells directly to candidates online.

The business is privately held with no disclosed parent company, institutional investors, or funding rounds. Headcount sits in the 11-50 band, the firm is headquartered in Paris (37 rue de la Rochefoucauld, 75009), with a listed presence in Lille and a French-only consulting footprint. Revenue derives from professional services fees on CSE mandates and one-time course fees from Concours; no public revenue, ARR, or pricing for consulting mandates is disclosed. Go-to-market relies on a content-rich website, newsletters, webinars (including a partnership with URSSAF dated 2026-06-22), and direct outreach to CSE members, with no disclosed technology stack, AI capabilities, or software-as-a-service product.
