What Groupe Streiff does

Groupe Streiff is a French family-owned industrial services group founded in 1930 in Grenoble and headquartered in Saint-Martin-le-Vinoux, operating through three wholly-owned subsidiaries — STREIFF, EOLYA, and PIC — across the Auvergne-Rhône-Alpes region. It delivers the full lifecycle of HVAC (heating, ventilation, air conditioning), plumbing, special fluids (stainless-steel and plastic piping for laboratories and industry), plasturgy (laboratory furniture and special-fluid plastic fabrication), and industrial metallurgy (boiler-making, sheet metal work, industrial maintenance) services for tertiary, industrial, healthcare, education, tourism, and housing clients. Reported consolidated revenue is €47.3M in 2025 with approximately 240 collaborators across 10 regional sites.

The group's business model blends project-based construction and installation work with a substantial recurring maintenance base of 900 contracts, complemented by managed-services arrangements including Global Performance Contracts (Marchés Globaux de Performance) with guaranteed energy outcomes and Public Service Delegations for district heating networks (e.g., Villard de Lans 2016-2026). Go-to-market is enterprise field sales executed by account managers under Commercial Director Sylvain Audra, supplemented by event-based relationship building through the FC Grenoble Rugby sponsorship and presence in trade publications such as Génie Climatique Magazine. Notable customer relationships span CEA, ST Microelectronics, Soitec, VICAT, Université Lumière Lyon II, Mairie de Villard de Lans, ACTIS EHPAD, and Belambra, demonstrating credibility across both private industrial and public-sector procurement channels.

Technically, the group differentiates through in-house engineering offices with BIM 3D REVIT design capability, MASE safety certification (covering STREIFF and PIC), and specialized niches such as clean-room exhaust networks and the recently introduced mobile ash-aspiration unit for biomass boiler residue valorization. Leadership is third-generation family under President Pierre Streiff (recipient of the Chevalier de l'Ordre National du Mérite in 2022), with division-level direction by Emmanuel Ustjanowski (STREIFF DG), Mickaël Darmizin (EOLYA DG, appointed October 2024), and Johan Capot (PIC Director, installed after the 2022 acquisition). The 2022 acquisition of PIC added industrial metallurgy depth, while the 2023 divestiture of GILLET and 2024 openings of two new EOLYA agencies indicate active portfolio shaping and regional fill-in.

• IDEX Energies: Independent French energy services company focused on HVAC operation, energy performance and biomass/district heating networks — a very close model to EOLYA's recurring services and Global Performance Contracts approach.

Broad incumbents

• Vinci Facilities: Multi-technical facility services business of the Vinci group covering HVAC maintenance and building performance contracts; competes with EOLYA on maintenance tenders and P2 contracts.
• Dalkia: EDF subsidiary specializing in district heating networks, biomass and energy services for communities — the most direct large-scale reference for Streiff/EOLYA's Villard de Lans district heating concession activity.
• Bouygues Energies & Services: Bouygues Construction's HVAC, energy and facility management arm; broad incumbent competing for large tertiary and public infrastructure projects in the same Auvergne-Rhône-Alpes market.
• SPIE: Leading French multi-technical services group covering HVAC, electrical and facility management across France; competes with all three Streiff subsidiaries but at materially larger scale and broader geographic reach.
• Eiffage Énergie Systèmes: Eiffage's multi-technical division covering HVAC, electrical and energy services for buildings and industry; broad incumbent with comparable service portfolio across Streiff's geographic markets.
• ENGIE Solutions: Subsidiary of ENGIE providing HVAC, multi-technical and energy services in tertiary buildings and industry; directly competes for the same public and private tenders as Streiff but with substantially greater resources.
