From Pioneer to Market Leader
What began in Geneva in 1967 as a small cleaning company is now the leading provider of comprehensive facility services in Switzerland. For 60 years, ISS Switzerland has been consistently evolving - from a traditional cleaning provider to a strategic partner for all aspects of building operations.
On December 12, 1967, the Danish ISS Group founded Swan Clean SA in Geneva - one of its first country offices outside Scandinavia. What began as a test market for new services became a Swiss success story.
