What Diagma does

Diagma is an international consulting firm founded in 1973 in Paris by Jean-Patrice Netter, specializing exclusively in Supply Chain Management across strategy, design, planning, operations, and transport. The firm serves large enterprise clients in eight vertical segments — Distribution, Assembly Industry, Process Industry, Luxury & Fashion, CPG & Agri-food, Health & Pharma, Services, and Technology — with named customers including LVMH, Carrefour, Groupe Renault, Saint-Gobain, Pierre Fabre, Bonduelle, DHL, and Evian-Volvic. Headquartered in Paris at 103 rue la Boétie with offices in São Paulo, Rio de Janeiro, Seattle, and Danvers (Massachusetts), the firm operates across EMEA, LATAM, and North America.

Diagma's intellectual property centers on two proprietary assets: Dialog, a registered network design and optimization software (with a 2025 version integrating global transport, labor, and carbon balance databases), and Onde Verte (Green Wave), a registered-trademark production-planning methodology that synchronizes workstations into virtual production lines, claiming lead-time and work-in-process reductions of 3x to 12x. Service lines include Supply Chain Strategy, Network Design, S&OP/IBP, Logistics Operations, Transport Performance, APS consulting across vendor platforms (Blue Yonder, Kinaxis, Relex, Azap), and the APPEL D'AIR modal-shift program partnered with the AI Cargo Foundation for transport decarbonization.

The business model is project-based, bespoke B2B consulting sold directly by partners and senior managers to client decision-makers — Directeur Supply Chain, Directions des Opérations, DG — with no channel intermediaries. Pricing is quote-based and non-public. The firm is independent, founder-controlled, and self-financed (no disclosed funding rounds, no parent company), executing 15-20 logistics network redesign projects per year with a partner-led delivery model that places associates directly on client missions.
