One stack. One jurisdiction. Two European champions.
The partnership combines Sirma’s agentic enterprise platform Sirma.AI with Schwarz Digits’ German-based sovereign cloud infrastructure STACKIT, delivering a fully European AI stack built for the governance and compliance demands of today’s enterprise.
Sirma Group Holding JSC (Sirma), a European enterprise technology company, and STACKIT, the cloud and colocation provider of Schwarz Digits, today announced a strategic partnership that marks a defining moment for sovereign AI adoption in European enterprises. The collaboration establishes a comprehensive commercial and go-to-market framework - covering reselling, joint marketing, and referral activities through which Sirma.AI’s Enterprise platform will be available on and through STACKIT’s cloud infrastructure, ensuring that AI workloads for European organizations remain entirely within European jurisdiction.
The partnership directly addresses one of the most pressing challenges facing European organizations today: how to deploy production-grade artificial intelligence without compromising data sovereignty, regulatory compliance, or operational control. As enterprises across financial services, manufacturing, logistics, and the public sector accelerate their AI adoption, the question of where data goes and who can access it has become a board-level concern and a genuine competitive differentiator.
Through the alliance, organisations gain access to Sirma.AI’s Enterprise platform - running within STACKIT’s certified European cloud environment, enabling intelligent, agentic automation across complex business processes. This combination delivers seamless integration with the sovereignty, security, and compliance standards that European enterprises demand without compromising capability or performance. Joint development initiatives, shared go-to-market strategies, and early access to platform innovations will further accelerate time-to-market for enterprise clients across the continent.
This partnership with STACKIT represents a major milestone for Sirma. By combining our deep AI technology expertise with STACKIT’s robust European cloud infrastructure, we are uniquely positioned to deliver secure, scalable, and innovative solutions that directly address our customers’ most critical challenges.
