Chaintrier Avocats

What Chaintrier Avocats does

Chaintrier Avocats is a Paris-based French law firm (operating as Chaintrier Avocats by Cogep, a société d'exercice libéral par action simplifiée) that provides integrated legal advisory and litigation services across seven practice areas: Corporate (M&A, private equity, LBO, governance), Tax Law, Business Litigation & Criminal Law, Press Law, Compliance, Economic Law (competition and distribution), and Labor/Employment Law, plus specialized commercial lease advisory. The firm serves French and international companies — both listed and unlisted — investment funds, and corporate executives, with a client roster that includes Ipsos, COGEP, Tata Consumer Products (via Artal Asia), Seafrigo, AssoConnect, and the Eddia group. Disclosed mandates range from mid-cap M&A transactions (e.g., the €200M COGEP/Waterland minority-stake deal and the Ipsos/Omédia cross-border acquisition) to compliance, employment, and white-collar litigation matters.

The firm employs approximately twenty lawyers, the majority of whom are partners recruited from leading international and domestic firms (McDermott Will & Emery, White & Case, Linklaters, CMS, De Pardieu Brocas Maffei, Mayer Brown, EY, Dentons, DS Avocats, Oxynomia). It operates without any proprietary technology platform, software product, or API — legal services are delivered through traditional partner-led engagement models. Chaintrier monetizes exclusively through professional service fees negotiated on a per-engagement basis, with multi-year client relationships in some cases. The firm is structurally affiliated with COGEP, an accounting and advisory group, and leverages the HLB International network of ~40,000 professionals across 150+ countries to serve cross-border mandates. Its go-to-market relies on thought leadership (bilingual monthly labor law newsletters, partner press features in Décideurs and Option Droit & Affaires), LinkedIn presence, and selective event participation, supported by independent rankings in Décideurs Magazine (M&A, Private Equity LBO, Transactional Tax, Compliance) and Best Lawyers 2024.
