What Kalliope does

Kalliope is an independent French law firm structured as a SELARL (Société d'Exercice Libéral à Responsabilité Limitée), founded in 2008 and headquartered in Paris (98 boulevard Malesherbes, 75017) with a secondary office in Valence/Cléon d'Andran in the Drôme region, opened in 2022. The firm employs 11-50 staff and is co-led by partners including Jocelyn Duval, Nicolas Contis, and Tanguy d'Everlange. It is organised around eleven practice areas spanning both private and public business law: Energy & Infrastructure, Environment & Industry, Corporate – M&A – Private Equity, Real Estate – Construction – Urban Planning, Public Services, Compliance – RSE (Corporate Social Responsibility), Employment – Social Security, Intellectual Property (launched May 2024), Contract Drafting & Negotiation, Banking – Finance – Regulated Funds, and Litigation – Arbitration – Mediation.

The firm's offering is built on a transversal model that combines private law advisory (M&A, financing, contracts) with public law expertise (public procurement, PPPs (public-private partnerships), administrative litigation), particularly for clients in regulated sectors such as renewable energy, environment, infrastructure, and real estate. Its client base spans enterprise and mid-market buyers across energy (Neoen, EDF Renouvelables, IDEX, Green Neon), banking/insurance (Banque des Territoires, April), aerospace (Safran Aerosystems), consumer (METRO AG, StaffMe), luxury (Dreyfuss), and engineering (Assystem), as well as public sector entities (collectivités territoriales, établissements publics). The firm has cross-border reach via membership in the IUROPE European alliance and a partnership with Orko Avocats (Nantes Bar).

Kalliope operates a sales-led, relationship-driven go-to-market in which client acquisition is driven primarily by directory rankings (Legal 500, Chambers, Best Lawyers, Leaders League/Décideurs), transaction press releases, and referrals rather than outbound selling. Revenue is generated through professional service fees for advisory, transactional, and litigation mandates, with pricing structured per matter (hourly, fixed, or success-based) but not publicly disclosed. Marketing channels include the firm's bilingual website (kalliope-law.com), a newsletter, LinkedIn presence, training/conferences, and an annual artistic sponsorship programme. The firm holds no patents, no proprietary technology, and no AI/ML capability — it is a pure professional services business with standard web infrastructure.
