What CORYS does

CORYS is a French dynamic simulation company founded in 1991 and headquartered in Grenoble, with subsidiaries in the United States (Jacksonville, Houston), India (Pune), and Cyprus (Nicosia). The company designs, builds, and services safety-critical training and engineering simulators across three divisions: Power Simulation (nuclear, thermal, hydraulic, networks), Transport Simulation (freight, high-speed rail, metro, tramway), and Process Industries Simulation (oil and gas, refining, petrochemicals, chemicals, hydrogen, batteries). Its customer base consists of regulated industrial operators and equipment manufacturers — including EDF, Framatome, SNCF, NS, RATP, BNSF, Siemens Mobility, Hitachi Rail, and Stadler — operating in more than 60 countries.

The technology stack combines the proprietary INDISS PLUS dynamic simulation software for process industries with Unreal Engine-based CGI environments (CORYS achieved Official Epic Games Service Partner status in March 2026), proprietary train dynamics models, and the cloud-delivered SODA platform that runs training on tablets and laptops. Product families include full-cab replica simulators, the SIMBOX desk simulator line, the Ultra Light Simulator (more than 100 units delivered since 2019), the ERTMS/ETCS simulator certified across seven European countries, the CBTC simulator for metro operators, and the nuclear Fuel Loading Machine simulator. The Competence Plus SaaS e-learning platform extends the product surface into subscription-based training delivery for process-industry clients including Petrobras, OMV, Axens, Veolia, and DS Smith.

Revenue is generated through three primary mechanisms: one-time sales and delivery of custom-built simulators and supporting visual databases, multi-year maintenance and support contracts (e.g., a 7-year contract with NS for compact simulators), and recurring SaaS via the Competence Plus e-learning platform and SODA cloud deployment. Pricing is quote-based and project-specific, driven by complexity, route-database scope, and integration effort. The go-to-market is enterprise field sales with dedicated account managers for major operators, supplemented by OEM specification channels (Siemens Mobility, Hitachi Rail, Stadler) and regional subsidiaries serving North America, South Asia, and the Middle East/Africa. CORYS is privately held by EDF and Framatome, both of whom are significant customers for nuclear simulation work, including the COCASE fleet renovation program and the EPR2 reactor engineering simulator awarded by Edvance.
