CloudSigma

What CloudSigma does

CloudSigma is a privately held sovereign cloud IaaS platform, founded in Zurich, Switzerland in 2009 and incorporated as CloudSigma Holding AG. The company builds and operates a multi-tenant IaaS platform based on KVM, VMware, VPC and ARM virtualization, with native storage, networking, security, billing/metering and API automation layers, supplemented by GPU compute (NVIDIA A100 passthrough/vGPU/MIG) and an AI gateway product (TaaS) that exposes an OpenAI-compatible API across 40+ third-party models with governance and sovereign routing controls. CloudSigma holds nine independent certifications covering ISO 27001, 27017, 27018, 20000-1, 9001, 14001, SOC 2, PCI-DSS, GDPR, and CSA STAR Level 1, and operates infrastructure across 40+ regions in 35+ countries including Switzerland, Germany, UK, Netherlands, France, Sweden, Austria, Saudi Arabia, Philippines, India, Australia, the US and Mexico.

CloudSigma sells exclusively through partners rather than direct to end users. The Cloud-as-a-Service partner program lets telcos, MSPs, datacenter operators, ISVs, government IT buyers and SIs/VARs launch white-label sovereign cloud and AI services under their own brand on a revenue-share basis, with no upfront platform fees, no minimums and no per-core licensing. End-customer pricing is set by partners and billed per-second in five-minute metering segments, while partners earn transparent wholesale unit rates and a 15% lifetime referral commission is layered on through a separate Referral Partner Program for consultants and communities. Documented partner launches include Virtual Vision in Saudi Arabia (2018), Eastern Communications in the Philippines (2019, with HPE), and Adisyn in Australia (2016), with reported partner-side growth of 45-150% in early quarters post-launch.

The company is bootstrapped with no disclosed external funding rounds or institutional investors; ownership is anchored by co-founder Robert Jenkin (CTO and co-founder, Cambridge-educated), with CEO Tony Limby (former BT Director of Hybrid Cloud Solutions), and external directors Philip Collerton (Uptime Institute/EdgeNebula), Anthony Foy (Uberall) and Paul Gheorghiu. Headcount is 51-100 employees and revenue is not publicly disclosed, with the platform serving partner-led sovereign-cloud and regulated-workload demand across Europe, MENA, APAC, Oceania, North America and Latin America.
