What Mediane Systeme does

Médiane Système is a French private engineering consulting firm (Bureau d'Études et d'Expertises) founded in 1989 in Le Pecq by current President Stéphane MADRANGE, operating with 101-250 employees across 5 European agencies. The firm delivers project-based, multi-year technical services to industrial clients in eight verticals — medical, railway, aerospace & defense, energy, industry & IoT, telecommunications, and automotive — with named customers including Alstom, RATP, Schneider Electric, Thales, Safran, EDF, Enedis, and Renault Trucks. Revenue is not publicly disclosed, the company is privately held without external investment, and growth has been organic over 35 years.

The firm's offering is structured around five technical expertises: custom secure real-time operating systems (bare metal, FreeRTOS, ThreadX, Zephyr, Linux RT, VxWorks with secure boot and BSP work); industrial networks (OPC-UA, IEC 61850, Single Pair Ethernet, Modbus, LwM2M, BLE/Zigbee/Wi-Fi/Thread); edge AI and embedded intelligence (predictive maintenance, computer vision, autonomous robots, LLM-assisted security log analysis); cybersecurity (IEC 62443 audits, CRA conformity, secure-by-design); and secure private 5G networks (RAN, core, edge/cloud applications). Differentiated compliance depth — spanning DO-178C, IEC 61508, ISO 26262, IEC 62304, IEC 62366, ISO 13485, ISO 21434, ASPICE, and ISO 27001 — is the firm's principal regulatory moat for safety-critical and security-cleared tenders.

The business model is professional-services consulting delivered through direct enterprise engagement: project-based, quote-priced assignments billed against statement-of-work scope, with multi-year framework contracts and on-site consultant placement at client sites. GTM is enterprise field sales into industrial primes, supported by participation in French industrial clusters (Systematic Paris-Region, Nuclear Valley, CLUSIF) and recurring presence at MILIPOL, SIDO, Solutrans, Forum Innovation Défense, and Open Source Experience. ESG credentials are actively managed — Ecovadis Gold 2025 (73/100), Gender Equality Index 90/100, HappyIndex Clients France 2024 ranked 2nd nationally with 90% client recommendation rate — and the firm is described as founder/management-owned with no disclosed private-equity or venture-capital backing.
