Built for long-term infrastructure partnerships.
CloudSigma helps service providers launch sovereign cloud and AI services under their own brand — without building the platform stack from scratch. Founded in 2009, we've spent 16 years learning what it takes to run reliable, compliant, globally distributed infrastructure at scale.
Sovereign cloud, engineered in Switzerland.
Founded in the heart of Switzerland by visionary Robert Jenkin, CloudSigma has grown into a global leader with staff locations and in-country clouds across the globe. Jenkin has assembled a dedicated team of leaders committed to the success of CloudSigma's global community of partners. We believe the wave of digitalization will transform the IT channel market, posing risks for those who don't evolve. Our mission is to empower IT service providers and prepare them for two key revolutions: migrating towards cloud services and enabling clients to monetize their business data. We offer secure, white label sustainable and sovereign fully-managed Cloud-as-a-Service solutions to meet these challenges.
Swiss Quality & Sovereignty
CloudSigma was founded and is headquartered in Switzerland — a jurisdiction synonymous with privacy, neutrality and rigorous data protection. Swiss data-protection law gives individuals and companies some of the strongest privacy guarantees in the world, independent of the EU and US legal regimes.
That heritage is built into how we operate: disciplined engineering, strict data governance and in-country data-residency guarantees our partners can stand behind when they sell into regulated and sovereignty-sensitive markets.
