What Langer does
Langer (legal entity: Dieter Langer GmbH) is a family-owned German building cleaning and facility management services provider founded in 1912 and headquartered in Mannheim. The company operates as the Langer Group, comprising Dieter Langer GmbH plus three wholly-owned subsidiaries — AGS Service GmbH (building and property services), IGD Service GmbH (transport and packaging), and Regio Catering & Service-Partner GmbH (catering) — and employs approximately 600 staff as of November 2024 (with a third-party source citing 800+ across the group).
The core service portfolio is built around professional building cleaning (Gebäudereinigung), subdivided into maintenance cleaning, construction and initial cleaning, glass and facade cleaning, industrial cleaning, and solar panel cleaning. Adjacent offerings include janitor/caretaker services (Hausmeister-service), broader facility management coordination, goods service (Warenservice), and catering delivered through the Regio Catering subsidiary. Technology consists of standard cleaning equipment and techniques rather than proprietary platforms; there is no app, no API, and no documented AI/ML capability. The company is TÜV certified under DIN EN ISO 9001, a member of the Gebäudereinigerinnung and Handwerkskammer, and has been a member of the Qualitätsverbund Gebäudedienste since 2005.
Langer sells directly to B2B customers via its website, phone, and email, with no intermediaries or resellers. Services are quoted on a custom basis per object rather than via standardized pricing. Field operations are delivered by on-site cleaning teams coordinated through centralized administration and object managers, with regular quality meetings and documentation. The company serves four primary verticals — Retail and Industry, Administration and Healthcare, Hotels and Restaurants, and Industrial Facilities — operating primarily in the Rhein-Neckar region while claiming Germany-wide coverage, with over 110 clean objects managed. The company is led by managing directors Evangelos Efstathiou (CEO-equivalent) and Dieter Langer (founder), with no external investors, PE involvement, or public listing.
