What Geomod does

Geomod (operating as 'Geomod by Coexya') is a French GIS (Geographic Information System) software publisher and distributor founded around 1997 and headquartered near Lyon, with a second engineering office in Brest dedicated to marine geomatics. The company serves three specialised verticals: marine geomatics (bathymetric chart production, ENC management, port and marina navigation), wave propagation (outdoor acoustic simulation and electromagnetic field exposure modelling), and water management (hydraulic modelling software support, training and operational accompaniment). Its core proprietary stack includes the Calhypso bathymetric chart production tool co-developed with SHOM, the PortAll port navigation application integrating the IHO S-100 standard, and the Mithra range (MithraSIG, MithraREM, RemOnline) co-developed with CSTB on a high-performance wave propagation calculation engine; Geomod also distributes NEC Software Solutions' SIS 3D GIS technology (since 1999) and supports Autodesk Water products (InfoWorks ICM, InfoDrainage, InfoWorks WS Pro, InfoAsset) following the 2026 transition to an Arkance-led distribution model.

Geomod monetises through a mix of subscription software licensing for its proprietary products, channel-distributed third-party software with attached support, Qualiopi-certified training services, and bespoke operational accompaniment (model auditing, optimisation, data structuring, platform migration, AMO). Go-to-market is sales-led and largely direct in France, supplemented by channel partners OceanWise (UK), Svantek Italia (Italy) and Arkance (Autodesk Water in France), with international expansion of Calhypso into Norway and Canada via direct engagement with national hydrographic services. The company targets large enterprises, ETIs and public-sector bodies — a base of 370+ customers including SHOM, Ifremer, Naval Group, Haropa Port, Veolia, Suez, CNR, Egis, Bruxelles Environnement, Rennes Métropole and ANFR — with several relationships spanning 15-20+ years.

Since the 2022 acquisition by Coexya Group, Geomod has continued to operate as a focused brand while pursuing selective expansion: a 2025 tripartite partnership with CGX AERO and Nexio (EM4Flight for Thales air traffic management) extends the Mithra stack into aviation, PortAll Mobile and S-100/S-102/S-111 support position the firm for the IHO standard transition, and a structured GeoCommunity platform plus per-vertical newsletters and user workshops underpin retention and upsell across the installed base.
