D6D

What D6D does

D6D (SAS D6D) is a privately held French management consulting firm founded in 2000 and headquartered in Sète, France, that advises liberal healthcare professionals — primarily dental surgeons and pharmacists, with selected services for architects, notaries, nurses, and other regulated professions — on legal architecture, fiscal optimization, and practice management. The firm's core offerings address decisions over the SELARL, SELAS, and SPFPL structures, including setup, holding creation, associate integration, and ongoing SEL management, alongside fiscal strategy (IS vs. IR, salary vs. dividend, Madelin contracts, depreciation planning) and management consulting (profitability analysis, ratio benchmarking, business plans). Services are organized around five pillars: Strategy, Legal Architecture, Fiscal Optimization, Management, and Personalized Accompaniment.

The firm combines senior consulting expertise with a recurring technology-enabled subscription. Since December 2023, D6D has offered the Offre de Suivi D6D x Masterdoc, a 490 EUR TTC/month subscription (no commitment) that integrates Masterdoc's automated data-retrieval dashboard with bi-annual advisory sessions, continuous remote support, SEL and associate management, annual legal document drafting, and access to the annual seminar at the Grand Hôtel de Sète. The firm's core technology is human expertise in French liberal profession law rather than proprietary software; Masterdoc is the only integrated technology and is positioned as a partnership rather than in-house product.

D6D acquires and retains clients through an event-driven, consultative sales model. The firm runs a dense calendar of in-person conferences and seminars across France (Toulouse, Lyon, Marseille, Bordeaux, Paris, Strasbourg, Avignon), often co-organized with dental industry partners (Henry Schein, La Medicale, Weclever Dental, Gorriz, ADPG Provence). Customer testimonials are published via Opinion System (ISO 20252 certified). The firm states it has accompanied more than 1,200 liberal professionals and supported more than 1,200 SELARL and SPFPL structures since 2000. Ownership is founder/associate-led with three principal associates (Yorick Chauviere, Cyrille Agot, Laurent Rodier) and founder Stephane Vial; no external investors, M&A, or funding rounds are reported.
