Immobiliengruppe Rhein-Neckar (IGRN) Tech Stack

German real estate operator managing 100,000+ residential units and 2M sqm commercial space

Real Estate Mannheim, Baden-Württemberg 501–1,000 employees Founded 1947 Privately Held

IGRN is a consolidated property management and services group operating across Germany with scale: 100,000+ residential units and over 2 million square meters of commercial space under management. The tech stack is operational (Office, SQL, Sage, LucaNet) rather than forward-looking—no cloud data platforms, no modern analytics—while hiring remains concentrated in operations (63 roles) with only 10 engineering positions open. Active projects center on building renovation and HVAC modernization; concurrent pain points around digitizing accounting, tenant insolvency, and network security suggest the organization is managing legacy operational complexity rather than scaling tech-first.
