What Kleine does

Kleine Reinigungs- und Dienstleistungsgesellschaft mbH is a Berlin-based professional cleaning and facility services provider founded in 1990 by brothers Hans-Joachim, Uwe-Detlef and André-Patrice Kleine, operating under private ownership of the charitable Kleine Stiftung since 2015. The company delivers five integrated service lines — Gebäudereinigung (building cleaning), Hotel-Services, Spezialleistungen (specialized cleaning including monument preservation and construction final cleaning), Medizin & Gesundheit (medical and healthcare facility services), and the differentiated Hygiene 4.0 module for medical facilities — to roughly 20+ named enterprise clients across luxury hospitality, hospitals, federal government, cultural institutions, media and higher education, primarily in Berlin, Brandenburg and Mecklenburg-Vorpommern. Technology is concentrated in the Hygiene 4.0 stack: the Visionclean Control digital performance and room directory, Lumitester PD-30 ATP measurement with LuciPac Pen, and the ProMop textile reprocessing system, all operating under DIN 13063 hospital cleaning standards and supported by five ISO certifications (9001, 14001, 50001, 27001, 45001) and a Fachbetrieb Denkmalpflege specialist credential since 1998.

Kleine employs 800+ people, including 300+ dedicated to hotel housekeeping through the legacy HSB GmbH division, and runs an in-house apprenticeship program established in 1999 that has produced skilled Gebäudereiniger and Handwerksmeister. The business model is a recurring B2B enterprise field-sales motion with no channel intermediaries: pricing is quote-based, anchored to client-specific service specifications (Leistungsverzeichnis) on monthly billing cycles with 14-day payment terms and tariff-wage pass-through clauses. Service delivery is organized by client 'object' (specific building or facility) with dedicated supervisors and object managers. The GTM motion targets large institutional accounts directly through the company website, LinkedIn and direct sales contacts, and growth is funded entirely from operations — no external funding rounds or PE/VC investors are reported.
