The company's technical differentiators include ERTMS safety equipment installation and certification, expertise in the transition from GSM-R to FRMCS rail communications, ECM (Entity in Charge of Maintenance) certification from the European Railway Agency, and regulatory compliance knowledge across France, Germany, Spain, and Italy. It serves a customer base of more than 150 operators and transport authorities across Europe and selected international markets (notably Senegal), with named clients including Eurostar, Thalys, Hexafret, RATP Florence, CFL Luxembourg, Transdev Dublin, and municipal operators in Rouen, Montpellier, and Lille. Masteris holds Ecovadis Silver and AFAQ/ISO 9001 quality certifications.

Masteris generates revenue primarily through professional services engagements on a project-based, quote-driven pricing model, supplemented by spare parts supply. Go-to-market is direct enterprise sales with dedicated experts assigned to each client project, supported by content marketing, case studies, industry events, and a professional website organized by client challenge and equipment type. CEO Rémi Peltier leads the company, which employs between 101 and 250 people and operates as a private entity with no external funding rounds or public listing.
