What Artelys France does
Artelys is a French-headquartered mathematical optimization and energy system modeling firm founded around 2003, operating as a privately-held Société par Actions Simplifiée. The company develops proprietary optimization solvers (Artelys Knitro for nonlinear and MINLP problems, Artelys Kalis for constraint programming and scheduling) and the integrated Artelys Crystal software suite covering multi-energy simulation (Crystal Super Grid), territorial energy planning (Crystal City), digital twins (Crystal Energy Explorer), operational asset management (Crystal Energy Planner), resource planning (Crystal Resource Optimizer), logistics network design (Crystal Network Designer), statistical forecasting (Crystal Forecast), and sovereign HPC (Crystal HPC). It also distributes FICO Xpress and AMPL on a marketplace basis.
Artelys serves primarily European Transmission and Distribution System Operators (Swissgrid, RTE, TenneT, Elia, AST, Litgrid, Elering), energy exchanges (EEX, Powernext), EU institutions (JRC, CRE), energy-intensive industrials (Toyota, Hitachi Energy, Brookfield Renewable), transport operators (SNCF, Nice Airport), and government/public agencies. A distinctive capability is its role as the developer of market clearing engines for pan-European platforms including MARI (mFRR balancing), TERRE (replacement reserves), PICASSO (aFRR), Guarantees of Origin auctions, and the Common European Merging Function for CorNet.
Revenue is generated through three streams: software licensing (Knitro, Kalis, Crystal suite via subscription or perpetual license with support contracts), high-end scientific and technical consulting (energy system studies, regulatory assessments, market design analysis), and market clearing engine licensing to exchanges and TSO platforms. The go-to-market is enterprise field sales targeting large utilities, TSOs, DSOs, industrial firms, and government bodies, supplemented by inside sales, a customer portal, and channel partnerships (FICO, AMPL). The company operates through subsidiaries in France (Paris HQ, Nantes, Lyon), Belgium, Spain, Italy, Switzerland (Sion, established April 2026), Canada (Montreal), and the USA (Chicago).
