What GIG Facility management and engineering. does

GIG Facility Management and Engineering (legal entity: GIG Technology & Real Estate GmbH) is a privately held, family-owned German Mittelstand facility management and engineering group founded in 1998 by Torsten Hannusch and headquartered in Berlin. The group delivers full-lifecycle building services across four pillars — Technical, Infrastructural, Commercial, and Industrial Facility Management — supplemented by technical planning (HOAI 1-9), industrial engineering, energy services, and plant construction. Its customer base spans public housing companies, banks, industrial and pharmaceutical enterprises, universities, asset managers, hotels, and industrial parks, with named logos including ProPotsdam, HOWOGE, Siemens, Charité Berlin, Freie Universität Berlin, and Technologiepark Bergisch Gladbach. Operationally, GIG runs a dense nationwide footprint of 230+ locations across Germany (plus Austria and Switzerland) backed by 8 competence centers and ~200+ in-house technicians, and reports €25 billion in assets under management covering approximately 250,000 residential units and 500 commercial properties.

GIG monetizes through managed-service FM contracts, technical-planning and engineering professional services, energy services and supply (via subsidiary GIG Stromkontor GmbH), and asset-management fees embedded in long-term enterprise relationships. Vertical specialization is delivered through wholly-owned subsidiaries: GIG pharmasite technology GmbH for GMP/FDA-compliant pharma and life-sciences FM (founded 2011), GIG Wohnimmobilien for residential portfolios, GIG hospitality technical solutions for hotels, and the 50/50 joint venture DIM Engineering GmbH (with DIM Deutsche Immobilien Management, established 2018) for technical property management at 13 additional locations. Underlying the service delivery is a proprietary digital stack — a Digital Betreiberplattform operator platform, GIG Nutzer-App tenant app, eSiteService, and fully digitized Kleinreparaturenmanagement — that delivers roughly 20% process-cost reduction and supports tenants in ~70,000–80,000+ apartments. Leadership transitioned in 2023 with Dr. Lisa Hannusch joining as managing partner (innovation, M&A, energy, environmental technology), and in February 2025 Hardy Hünich became Chairman of the GIG Technology Group management board. GIG's most recent strategic pivot, in May 2026, is the formal launch of data center and AI factory facility management services alongside a groundbreaking for a major digital-infrastructure project in Oehna.
