The company's Facility Service division manages commercial, infrastructural, and residential properties, offering services such as cleaning, security, catering, and garden maintenance. Its Industry Service arm provides maintenance, technical cleaning, and production support to various industrial sectors. The Aviation Service division handles ground operations at major German airports, including Frankfurt and Berlin. WISAG's commitment to innovation is evident in its adoption of building automation solutions to reduce energy costs for clients. The company has also partnered with Yokogawa to develop specialized software for building management systems. In response to the Ukraine crisis, WISAG repurposed a hotel in Frankfurt to house over 600 women and children refugees, demonstrating its social responsibility. The company also established the "Kiwis" foundation in 2015 to promote educational opportunities for children. With a presence in Austria, Switzerland, Luxembourg, and Poland, WISAG continues to expand its reach while maintaining a focus on personalized service. The company's success is built on its ability to combine the flexibility of a small business with the resources of a large, family-owned enterprise.
