Klüh started as a small family-run cleaning business with only five employees but has grown exponentially, now employing over 40,000 people. The company has faced fierce competition in the service industry, adapting its operations and technology to remain relevant and successful. Today, their cleaning staff utilize modern tools such as tablet computers, which provide digital cleaning plans, enhancing efficiency and service quality.

The use of technology is a crucial aspect of Klüh’s operation, particularly at locations like Düsseldorf Airport, where cleaning routines are managed through detailed digital guides. This technological advancement not only streamlines their cleaning processes but also illustrates the company's adaptation to modern service standards. The deployment of such digital resources reflects a broader trend in the service industry towards increased efficiency and customer satisfaction.

Klüh's journey emphasizes the importance of innovation and scalability in the service sector. As the company continues to navigate a 'brutal' competitive landscape, its focus on integrating technology into traditional service roles highlights a significant shift in how service businesses operate, raising questions about the future of labor and service delivery in an increasingly digital world.
