What Parthema does
Parthema is an independent, partner-owned French business law firm (SELARL — Selarl Parthema Avocats, RCS Nantes 440 495 992), founded in 2011 from the merger of two Nantes-based firms established in 1936 and 1991. It is headquartered in Nantes with regional offices in Paris and Rennes, and operates with 14 partners and approximately 60 legal professionals organised across 11 disciplines: commercial and contracts, tax, real estate, social/employment, corporate, public, international, heritage/estate, intellectual property and digital, business difficulties, and health law. In November 2020 the firm extended its offering through Parthema Notaires, an interprofessional lawyers-notaries partnership — the first such structure in France's Grand Ouest region — covering authentic notarial acts, heritage planning, and real estate transactions.
The firm generates revenue through professional service fees for advisory engagements, litigation, and notarial work, serving primarily French PME (small and medium enterprises), ETI (mid-sized enterprises), and corporate groups, with a secondary segment of business leaders and family offices seeking integrated legal and notarial services. Its go-to-market is enterprise field sales via direct partner-led consulting across its three offices, supplemented by thought-leadership content (white papers, webinars, conference participation with bodies such as REPI, INPI, EDAGO, and Datamaniaques), an SEO-driven website, and a LinkedIn presence. There is no proprietary technology platform; the firm operates a third-party secure client extranet (parthema.secibonline.fr) for document exchange. The firm does not disclose revenue and is not publicly traded; ownership sits with the 14 partners and there is no institutional investor or parent company on the record.
The client base is diversified across software/technology (RCA, Zetaly, Kaemo), energy (Energies de Loire), audiovisual (Main Avenue Group), manufacturing (Groupe CPL-OP Emballages), and ESG/startup advisory (Good Steps, Imagination Machine). Engagements visible in the record span €700K to €15M+ deal values, with no single customer disclosed as accounting for a disproportionate share of revenue.
