What Kramer does

KRAMER GmbH is a privately held, family-owned building services provider headquartered in Heilbronn, Germany, founded in 1968. Operating as the KRAMER GRUPPE under the DBA KRAMER Gebäudedienstleistung, the company employs 3,000+ staff and is positioned as one of the largest building services providers in Süddeutschland (South Germany). Its portfolio spans maintenance cleaning (Unterhaltsreinigung), glass and facade cleaning (Glas- und Sonderreinigung using osmosis technology), full facility management covering infrastructural, technical, and commercial building services, and temporary personnel staffing under an ANÜ (Arbeitnehmerüberlassung) license. Vertical coverage includes insurance, banking, logistics, retail, industry, healthcare, public institutions, pharmaceutical (GMP-compliant), food (HACCP), and automotive customers.

Its technology stack rests on a digital object-management platform featuring the Krami mobile application for on-site object managers, GPS-supported logistics planning, a CRM system spanning reports, quality control, invoicing, fleet management, and inventory, and AI-driven autonomous cleaning robotics used for floor cleaning and surface disinfection. Chemical-free cleaning methods including ozonized water and osmosis-based facade cleaning underpin a sustainability positioning supported by DIN EN ISO 14001 environmental certification, alongside DIN EN ISO 9001 quality certification and ANÜ licensing. An AI recruiting assistant, Klina, supports high-volume hiring.

KRAMER generates revenue primarily through recurring cleaning and facility management contracts, supplemented by managed services and ANÜ professional-services revenue from temporary staffing. Go-to-market is direct enterprise field sales through regional object managers who serve as embedded customer contacts, with named anchors including MAHLE (118 deployed staff across multiple sites), EXPERIMENTA (since 2019), and Heilbronner Stimme (since 1973). The company is managed by Ralf Kramer and Rüdiger Holzäpfel and operates additional offices in Gerlingen (Stuttgart region) plus subsidiaries RTS GmbH, KRAMER Projekta, WIG (Wasser GmbH), and Naheland-GmbH.

Broad incumbents

• ISS A/S: Global facility services integrator headquartered in Denmark, with major German operations. Overlaps heavily with KRAMER's cleaning and facility management offerings but at vastly greater scale and with multinational key-account capability.
• Compass Group: UK-headquartered global support services group (including facility services and cleaning through its subsidiaries) with extensive German presence. Comparable at the portfolio and integrated-FM level, though anchored in contract catering.
• Hochtief Facility Management: Facility management arm of German construction major Hochtief, offering integrated FM and cleaning services. Comparable in building-cleaning and technical-management capabilities; significant scale advantage.
• Sodexo: Global French-headquartered facility management and food services group with significant German operations. Competes for the same enterprise and institutional facility-management contracts as KRAMER, though across a much broader service menu.

Direct peers

• Piepenbrock: Family-owned German building-services group offering cleaning, facility management, security, and personnel services — almost identical service portfolio and ownership structure to KRAMER, but national rather than regional.
• Dussmann Group: German-headquartered facility services provider (cleaning, security, catering, technical services) operating across multiple countries. Direct competitor with much larger scale; competes for enterprise and public-sector contracts in the same verticals.
• Kötter Group: German family-owned facility services provider with strengths in cleaning and security — comparable ownership profile, similar service mix to KRAMER, broader geographic spread across German regions.
• Wisag: Germany's largest facility services group (aviation, industry, building, cleaning) with national reach. Direct competitor to KRAMER in commercial cleaning and infrastructural facility management, with significantly larger scale and broader geographic coverage.
• Gegenbauer: Berlin-based building services and facility management company, one of Germany's largest privately-held FM providers. Comparable in offering (cleaning, technical/infrastructural FM, security) and provides a regional comp in a different German Länder.
• STRABAG Property and Facility Services: German subsidiary of STRABAG focused on technical and infrastructural facility management and cleaning. Direct competitor for commercial property cleaning and integrated FM contracts, with backing from a major construction group.
