Stuttgart-based Blockbrain has secured €17.5 million in Series A funding to accelerate the rollout of its enterprise AI platform designed to capture, structure and automate company knowledge.
The round was led by Alstin Capital and 13books Capital, with participation from the HARTING Family Foundation. Existing investors Giesecke+Devrient Ventures, LBBW Ventures and Mätch VC also increased their commitments.
The new capital will support product development, international expansion across the European Union and the UK, and further investment in security, governance and compliance capabilities.
Turning Tacit Expertise Into Digital Knowledge Twins
When experienced employees leave an organisation, they often take undocumented expertise, decision-making logic and established processes with them. Blockbrain addresses this challenge by enabling companies to create digital “knowledge twins” that systematically capture and structure expert know-how.
Within weeks, organisations can deploy AI-powered Knowledge Bots that store specialist insights, map decision logic and make experiential knowledge available across teams and locations. Customers report measurable efficiency gains, with some achieving weekly time savings of up to 15 percent through the use of digital knowledge twins.
The platform’s architecture is designed to minimise hallucinations and misinformation, ensuring that enterprise AI outputs remain reliable and auditable.

Strong Market Traction Across Regulated Industries
Blockbrain recorded fivefold revenue growth in 2025, driven by demand from knowledge-intensive and highly regulated sectors. Its client base includes companies such as Roland Berger, Bosch, Bosch Rexroth, Kärcher, Harting and Seifert Logistics Group.
The company positions itself as a provider of secure and trustworthy enterprise AI, particularly for industries where compliance, transparency and data sovereignty are critical.
Security, Governance And EU AI Act Readiness
Blockbrain differentiates itself through a strong focus on security and regulatory compliance. The platform is GDPR-compliant, ISO 27001-certified and prepared for the requirements of the EU AI Act.
Its multi-model architecture avoids vendor lock-in, allowing companies to retain control over their data and AI models. An independent benchmark conducted by Giesecke+Devrient awarded Blockbrain 92 out of 105 possible points, placing it significantly ahead of other tested enterprise AI solutions.
With the Series A funding, Blockbrain plans to expand its governance and compliance features, develop specialised AI agents and research workflows, and introduce fallback mechanisms to increase answer reliability and system availability.
Scaling Across Europe With Forward-Deployed AI Engineers
As part of its growth strategy, Blockbrain is expanding its presence across Europe and the UK. The company is building a team of Forward-Deployed AI Engineers who work closely with enterprise clients to integrate AI agents into existing systems, either remotely or on-site.
Co-Founder and CEO Antonius Gress emphasised that companies lose critical know-how every day because expertise and complex decision logic are rarely captured systematically. By making tacit knowledge permanently accessible, Blockbrain aims to strengthen productivity and long-term competitiveness.
Co-Founder and CTO Mattias Protzmann highlighted that enterprise AI must go beyond model performance alone, stressing that security, data sovereignty and transparency are foundational for responsible deployment in corporate environments.
