Groupe Herve S.A.

What Groupe Herve S.A. does

Groupe Hervé S.A. is a privately held French industrial group founded in 1972 by Michel Hervé, operating through FINANCIÈRE HERVÉ as a holding company with a participative, intra-entrepreneurship-driven management model. The group is organized into three operational poles - Energy Services (Pôle Énergie Services), Industry (Pôle Industrie), and Digital (Pôle Numérique) - comprising 25 wholly-owned subsidiaries, 101 implantations across 6 countries, and approximately 4,000-4,350 employees. Core offerings span climate engineering, electrical and network engineering, building automation (GTB-GTC), cogeneration, refrigeration, custom industrial manufacturing (boilermaking, piping, sheet metal, hydraulics) for aerospace, naval, oil & gas, nuclear, food, and pharmaceutical sectors, renewable solar/biomass energy, and digital services (web development via iMDEO, audiovisual, training).

Technology and platforms include the proprietary NOE 3 remote metering and monitoring system (via ALERTEO), BIM GEM digital-twin modeling linked to GMAO for facility management, connected-object smart-maintenance solutions, and energy-performance services spanning audits, consumption tracking, and remote surveillance. The group has earned sector-leading sustainability certifications including the first French professional building labeled Très Haute Performance Energétique, the first French building to achieve Très Performant on all 14 HQE targets, and BBC/BEPOS designations.

Revenue is generated primarily through enterprise B2B contracts via the subsidiary network, combining one-time project installation work with multi-year recurring maintenance and energy-data service agreements. Distribution is decentralized across 25 subsidiaries, each managing its own enterprise client relationships within specialized verticals, supported by a partner portal for client intervention requests and energy-consumption tracking. Reported annual revenue is €750M with no external institutional or private-equity ownership documented; the group is founder-controlled with consistent M&A-driven expansion (MATHECO 2022, SEIM-N 2024, Bourbon Froid Océan Indien 2025) and greenfield entries (FABKIT 2021, HERVÉ PORTUGAL 2024).
