Safe Host is a Swiss data center owner and operator, founded in 2000 and headquartered near Geneva, that sells colocation and wholesale/hyperscale capacity across a portfolio of four operational data centers plus a fifth under construction, all located in Switzerland. As of 2022 the company’s four live facilities in the Geneva area, Gland, Avenches, and near Zurich comprised roughly 56 megawatts of IT load across about 25,000 square meters, with a fifth site being built in Beringen, in the canton of Schaffhausen. In May 2022, IPI Partners agreed to acquire a majority stake in Safe Host and fold it into its STACK Infrastructure platform, giving STACK a significant Swiss footprint alongside its existing Nordic and Italian data centers; Safe Host’s public-facing brand and sites have since been transitioning to the STACK name. Safe Host built its reputation on Switzerland’s political stability, strong data-protection laws, and hydro-powered renewable energy, marketing itself around a low-carbon ‘eco21’ sustainability program and 100% hydro-powered energy for its Geneva-area sites.
