Safe Host is a Swiss colocation and data center operator that designs, builds, and runs its own facilities for enterprise, financial-sector, and hyperscale clients, rather than reselling third-party space. Founded in 2000 and headquartered in Plan-les-Ouates near Geneva, the company built a network of five purpose-built data centers across Switzerland — in the Geneva area, Gland, Avenches, Rafz (near Zurich), and Beringen (Schaffhausen) — with a combined installed capacity described at over 76 MVA. In May 2022, investment firm IPI Partners acquired a majority stake in Safe Host and folded it into its STACK Infrastructure platform, and as of 2025 the company’s newer buildings (including the former SH4 and SH5 sites) have been rebranded under the STACK name, though the safehost.com domain and legacy branding trace the original Swiss operator’s footprint. Safe Host’s differentiator has long been its focus on serving Swiss regulatory and data-sovereignty requirements (FINMA compliance, ISO 27001/9001 certification) for financial institutions, multinationals, and international organizations that need in-country hosting.
