Sovereign AI from the model to the infrastructure. October 26, 2026 Where does the greatest potential of generative AI lie? Not in drafting emails, but where companies work with their core knowledge - whether in laboratories, research and development, on assembly lines, in manufacturing, in hospitals and medical practices, or in public administration. Wherever specialized expertise is the decisive competitive advantage and strict regulatory requirements apply at the same time, AI can make the biggest difference. Especially in these sensitive areas, integrating AI securely and productively is particularly demanding. It is long past being just about the performance of an individual language model. Instead, the decisive questions are: Where is data processed? Which models are allowed to access it? Who controls permissions? And how can every processing step be tracked in an audit-proof manner? Blockbrain, Aleph Alpha, and STACKIT - the cloud provider of Schwarz Digits - are joining forces to deliver holistic, sovereign enterprise AI. Together, they provide an end-to-end solution that combines the cloud, the model, and a sovereign orchestration platform. All data remains entirely in Europe, from the platform to model inference. Together for sovereign Enterprise AI. The collaboration between Blockbrain and Aleph Alpha spans multiple levels. Aleph Alpha focuses on developing high-performance models, while Blockbrain provides the platform for deploying AI productively across enterprises - from integration into existing system landscapes to the governance of data and model access. With Kolibri, Aleph Alpha expands Blockbrain's model portfolio with an additional option. This specialized large language model was designed by Aleph Alpha in Germany and trained entirely in Europe. In addition, open foundation models such as Llama, GPT-OSS, Qwen-3, and Gemma are available via STACKIT AI Model Serving - which is fully integrated into the Blockbrain platform - and operated on European servers. In addition to Kolibri, open foundation models such as Llama, GPT-OSS, Qwen-3, and Gemma are available and hosted in Europe through STACKIT. This gives organizations a wide range of models for different use cases and performance requirements. Companies decide for themselves which models to approve for which use cases. This selection can be managed centrally and tailored to specific performance, data privacy, and compliance requirements. Sovereignty across the entire AI stack. For companies to benefit from this freedom of choice, infrastructure, model, and platform must work together seamlessly. Each layer fulfills a distinct role and helps enforce data flows, access rights, and governance policies consistently across the entire AI application. STACKIT's sovereign infrastructure and Blockbrain's governance capabilities help organizations comply with the GDPR and the EU AI Act. These capabilities include controlled data processing, clearly defined access permissions, and traceable processing steps. The foundation is STACKIT, the sovereign European cloud infrastructure from Schwarz Digits, the IT and digital division of the Schwarz Group. STACKIT is certified under ISO 27001, ISO 27017, and ISO 27018, holds a BSI C5 Type 2 attestation, and is aligned with the requirements of the GDPR and the EU AI Act. Customer data is neither stored nor used to train the models. Especially when AI works with research data, formulas, engineering specifications, or manufacturing parameters, having control over where data is processed is critical. Benefits of sovereign orchestration with Blockbrain: * Granular access controls: Precise management for users, teams, and applications. * Flexible model choice: Use Kolibri and open models such as Llama, Qwen-3, or Gemma depending on the use case and data protection requirements. * Intelligent model routing: The platform automatically selects the most cost-effective model for each request. In one real-world case, token costs for specific processes dropped by up to 90 percent. * Traceable data flows: Central audit and governance mechanisms provide transparency across relevant processing steps. * Defined retention periods: Clear rules for storing and deleting prompts and outputs. * Modular interchangeability: Seamless switching between models and infrastructure components without disrupting systems. This allows compliance, data privacy, and information security requirements to be embedded consistently into the technical architecture. Deploying AI where it creates the greatest value. The partnership is designed for organizations where data privacy, IP protection, and governance are paramount: * Public administration working with personal data. * Regulated enterprises where compliance and traceable data processing are non-negotiable. * Industrial companies whose competitiveness relies on proprietary know-how and intellectual property. * Pharma and MedTech companies working with sensitive research data and clinical information. STACKIT, Aleph Alpha, and Blockbrain combine sovereign infrastructure, European and open model options, and a central orchestration platform into an end-to-end, economically scalable setup for generative AI in sensitive and regulated environments.
Sovereign AI Summit 2026: Scaling AI securely and productively. September 24, 2026 Many companies have already successfully implemented their first AI use cases. However, transitioning from individual pilots to productive, enterprise-wide AI adoption often involves complex challenges: data remains trapped in silos, answers vary depending on the source, and critical processes frequently depend on the knowledge of specific individuals. At the same time, requirements for security, compliance, and integration into existing systems such as SAP and Microsoft continue to rise. At the Sovereign AI Summit, STACKIT, STAR, and Blockbrain combine their respective perspectives on productive enterprise AI deployment: from sovereign European cloud infrastructure to strategy, integration, and implementation, all the way to the enterprise AI platform. The focus will be on real-world experiences, such as successfully implementing AI and complex SAP integrations, as well as on an outlook on the Blockbrain product roadmap. What to expect. * Sovereign Governance: How companies combine data sovereignty, security, and innovation * Customer Example - AI Pilot: How to successfully launch into practical AI application with the right use case * Customer Example - SAP Integration: Securely integrating AI into complex corporate and ERP environments * Blockbrain Roadmap: A look ahead at the future development of the Enterprise AI Platform and Eddy At a glance.

Blockbrain secures 17.5 million euros in Series A funding. Digital knowledge twins instead of know-how outflow. Blockbrain scales secure enterprise AI. News by Marc Nemitz - Stuttgart, 12. February 2026 When experienced employees leave a company, valuable knowledge is often lost: decision-making logic, methods and established processes disappear and have to be painstakingly rebuilt. The Stuttgart-based tech scale-up Blockbrain addresses precisely this problem with an AI platform for trustworthy knowledge agents. The company has now completed a Series A financing round of 17.5 million euros. Investor base for next growth phase. The financing round is led by Alstin Capital and the London-based technology investor 13books Capital. The HARTING Family Foundation is also participating. Existing investors Giesecke+Devrient Ventures, LBBW Ventures and Mätch VC are increasing their commitment. Blockbrain plans to use the fresh capital to significantly accelerate product development, sales and scaling, particularly in Europe and the UK. Rethinking knowledge management with AI agents. Blockbrain's platform enables companies to systematically digitize critical specialist knowledge and experience and make it available as so-called knowledge bots. These AI agents act as digital knowledge twins of experts and store ways of thinking, decision-making logic and methodological knowledge. Companies lose valuable expertise every day - not due to negligence, but because knowledge and complex decision-making logic have hardly ever been systematically stored. Antonius Gress, Co-Founder & CEO Blockbrain Within a few weeks, such knowledge twins can be set up and used throughout the organization. The aim is to make knowledge permanently available, augmentable and automatable and thus create a calculable competitive advantage. Market feedback and increased sales. Business development shows that the approach is in high demand: Blockbrain quintupled its turnover in 2025. Customers include companies from knowledge-intensive and highly regulated industries, including Roland Berger, Bosch & Bosch Rexroth, Kärcher, fischer, Harting, Eberspächer, Bardehle Pagenberg, CHG Meridian, Domcura and Seifert Logistics Group. In knowledge-intensive and highly regulated industries, expert knowledge determines quality and speed. If it is lost, there is a risk of costly productivity losses. Benjamin Kleinschnitz, Senior Investment Manager at Alstin Capital Axel Frey, CEO of the Seifert Logistics Group, reports weekly time savings of up to 15 percent thanks to the use of his digital knowledge twin. Security, governance and data sovereignty. A key differentiating factor for Blockbrain is its security and governance architecture. The platform is GDPR-compliant, ISO 27001-certified and fully EU AI Act-ready. Thanks to a multi-model architecture without dependence on individual AI providers, companies retain control over models and data at all times. If required, customer data can be stored in highly secure, regional cloud environments of the respective company. An independent benchmark by Giesecke+Devrient confirms the security claim: Blockbrain scored 92 out of 105 points, clearly setting it apart from other enterprise AI solutions. Expansion of engineering, product and market presence. With the Series A financing, Blockbrain is making targeted investments in the expansion of its team, particularly in forward-deployed AI engineers who support customers with the introduction, integration and operation of AI agents. At the same time, the company is driving forward new functions, including automated replacement and fallback processes to increase response reliability as well as new agent and research workflows for automated knowledge building.
