CITADIA

What CITADIA does

CITADIA is a French consulting firm specializing in urban planning, territorial development, and project strategy, founded in 1997 and operating as a wholly-owned subsidiary of Groupe SCET (the consulting arm of Caisse des Dépôts, a French state-owned investment institution) since 2017. The firm employs approximately 120 staff across five agencies in France and serves French public-sector clients including local authorities (collectivités territoriales), intermunicipal cooperation establishments (EPCI), and metropolitan areas. Activity has extended into French overseas territories including Polynesia. CITADIA operates through five complementary brands — Citadia Conseil (strategy), Merc/AT (project governance), Citadia Design (urban design), Even Conseil (operational consulting), and Aire Publique (public space) — covering the full chain from territorial diagnosis to operational implementation.

The firm's core intellectual property is a suite of proprietary tools — CITAVIZ (data visualization), CIT'adapt (housing adaptation), CIT'atten (vulnerability assessment), CITAfoncier (land analysis) — and a methodology framework branded DEX. These are used to support planning documents (PLU, PLH, SCOT), strategic studies, urban design missions, and project governance for public clients. The tools appear to be diagnostic and visualization platforms rather than AI-driven systems, and are monetized through embedding in client engagements rather than standalone licensing.

Revenue is generated through mission-based consulting fees tied to public-sector commissioning cycles. The business model is project-based professional services rather than product licensing, with revenue exposed to French local-authority budget cycles and state transfers. Anne Matysen has served as Directrice Générale since 2022, and the firm is preparing a merger with Habitat & Territoires Conseils, a complementary SCET subsidiary. Eric Dubertrand was appointed Directeur Général of SCET in 2026, completing a top-of-house leadership refresh across both the subsidiary and parent.

Core offering

Revenue is earned via project-by-project advisory mandates and public procurement contracts. The firm deploys proprietary analytical tools (CITAVIZ, CIT'adapt, CIT'atten, CITAfoncier) and the Diagnostic Expert methodology to deliver evidence-based territorial diagnosis, climate vulnerability assessment, and land consumption modeling.

The portfolio includes proprietary tools CITAVIZ (data visualization platform), CIT'adapt (climate adaptation), CIT'atten (energy/carbon scenarios), and CITAfoncier (land modeling), all supported by an innovative Diagnostic Expert methodology.
