Sevenstones

What Sevenstones does

Sevenstones is a Paris-headquartered boutique M&A advisory firm founded in 2007 by Élodie Le Gendre (formerly of Paribas and UBS) that exclusively serves French entrepreneurs, families, and shareholder-managers of PME and ETI companies through capital operations. The firm operates an integrated advisory practice spanning business sales (cession), acquisitions, fundraising (levée de fonds), leveraged buyouts (LBO), shareholder mediation, and governance consulting — all framed around its 'M&A for Good' philosophy and delivered through a regional network of offices in Paris, Nantes, Lyon, and a Montpellier-based business development presence covering southern France.

The firm's distinguishing operational asset is ADN Check®, a trademarked proprietary diagnostic methodology covering approximately 150 criteria across 7 thematic areas (visibility, competitive positioning, risk, organization, profitability, growth, impact) used to surface the singularity and intrinsic value of client companies. Sevenstones formalized its mission-driven positioning in 2023 by becoming an 'entreprise à mission', embedding three statutory commitments around long-term impact, team talent development, and sustainable finance promotion into its operating charter.

Sevenstones generates revenue on a bespoke, transaction-fee basis (no standardized pricing or recurring SaaS model), charging advisory fees for completed M&A mandates. The firm employs ~20 collaborators — most with prior experience at tier-1 institutions (Rothschild, Paribas, UBS, KPMG, PwC, Société Générale, Bpifrance, SODICA) — and grows through referrals, regional ecosystem participation, and content-driven marketing. There is no disclosed external investment, parent company, or public listing.
