What Stack Group does

Stack Group (ООО «Стек Групп», founded 2003, Moscow) is a private Russian managed cloud and data center operator selling under the M1Cloud brand. Its core offering is enterprise IaaS built on VMware and the Russian RUSTEK virtualization platform, supplemented by a protected cloud certified for Federal Law 152-FZ (GIS K1 and ISPDn UZ1) and an OpenStack-based public cloud. The portfolio spans compute, block/object/file/backup storage on NetApp and HPE, colocation in Tier III Moscow data centers (Top-10 per CNews, separated by 14+ km for DRaaS), network services (M1CloudWide), security (DDoS, WAF, Kaspersky MSSP), managed services (AutoMate), VDI, GPUaaS for AI workloads, and industry solutions for finance, retail, industrial, construction, telecom, and government customers.

The business model is enterprise subscription IaaS plus managed services, with recurring monthly billing on storage tiers and individual contracts for larger deployments. Go-to-market is direct enterprise field sales with a dedicated project manager and IT architect per client, supplemented by a partner/reseller program and a self-service portal. Revenue is not publicly disclosed; the company serves named Russian enterprise customers including Finam, Moscow Exchange, Rosgosstrakh, Interfax, and Infocom-Avia, and was the first in Russia to certify a 152-FZ-compliant protected cloud.

In 2025-2026 Stack Group has repositioned around AI infrastructure and AI security, launching GPUaaS and AI Cloud Solutions, introducing the proprietary Manageflow System automation platform, and integrating third-party AI security platforms cqrt(ai) and СЗИИ. It has also expanded vertical offerings (BIM Cloud for construction, franchise cloud, industrial cloud transformation, legacy migration services) and modernized its protected-cloud security perimeter. The company operates entirely within the Russian regulatory cloud market, leveraging sovereign-platform certifications (RUSTEK, Astra/Alt Linux, Red OS, FSTEC license) as a core go-to-market asset.
