Blockbrain, a GenAI agent platform out of Stuttgart that helps enterprises secure Europe’s knowledge expertise, has raised €17.5 million (£15.2 million) in Series A funding to strengthen its platform’s security and governance, advance specialised AI agents, and expand across Europe and the UK
The round is led by Alstin Capital and 13books Capital, with participation from the HARTING Family Foundation. Existing investors Giesecke+Devrient Ventures, Landesbank Baden-Württemberg Ventures, and Mätch VC have also increased their financial commitment. The company’s total funding to date amounts to €23 million.
“Companies lose valuable know-how every single day – not out of negligence, but because knowledge and complex decision-making logic have rarely been captured in a systematic way. With Blockbrain, we make tacit expertise permanently accessible and create a robust foundation for productivity and competitiveness. The successful Series A funding round gives us the momentum to scale this approach across Europe,” says Antonius Gress, co-founder and CEO of Blockbrain.
In the context of Blockbrain’s Series A raise, several other European AI and agent-oriented startups have secured notable funding in 2025–2026.
For example, EvoluteIQ (Swedish AI platform) secured a €44 million minority growth capital round to accelerate global expansion of its agentic AI automation platform, targeting end-to-end business workflow orchestration. PolyAI (London‑based enterprise conversational AI) raised €73.2 million in Series D to scale its enterprise voice agent technology for customer service applications.
On the security and supervision side, Overmind (AI agent security infrastructure) closed a €2.3 million seed round to build supervision layers for deployed AI agents, while Equixly (Verona‑based agentic API security) raised €10 million to scale its agentic platform for automated API security testing. Additionally, Qevlar AI (Paris‑based agentic SOC platform) secured €9.1 million to advance autonomous AI-driven security operations.
Taken together, these rounds illustrate a broader European funding trend in enterprise AI and agent-centric technologies throughout 2025 and into early 2026. While there are large scaleups like PolyAI and EvoluteIQ attracting substantial growth capital, smaller Seed and Series A rounds in adjacent niches such as agent security (Overmind), API protection (Equixly), and autonomous SOC platforms (Qevlar AI) signal diversified investor interest across both automation and safety-oriented segments.
Blockbrain’s Series A fits within this mid-range cluster of enterprise-focused AI funding, emphasising secure knowledge and governance capabilities that complement broader trends toward agentic, operational, and compliance-centric AI deployments in European organisations.
“Quality and reliability at Blockbrain do not simply arise from choosing a particular AI agent,” adds Mattias Protzmann, co-founder and CTO of Blockbrain. “From day one, we have focused on security, data sovereignty, and compliance. This strategy gives our customers control through full transparency. In a corporate context, simply relying on promises and the power of a model is, in our view, not enough.”
Founded in 2022, Blockbrain is an AI platform that enables companies to securely digitise expertise, processes, and decision-making logic and make them usable across the organisation. The company was founded by Antonius Gress (formerly Bosch), Mattias Protzmann (serial entrepreneur and co-founder of Statista), and Nam Hai Ngo (formerly Antler, WHU alumnus).
The aim is to counteract the shortage of skilled workers and structural inefficiencies in companies with an easy-to-use, no-code-based AI platform and to make internal know-how systematically usable, augmentable, and automatable.
In 2025, Blockbrain recorded a fivefold increase in revenue. Customers include Roland Berger, Bosch & Bosch Rexroth, Kärcher, fischer, Harting, Eberspächer, Bardehle Pagenberg, CHG Meridian, Domcura, and Seifert Logistics Group.
The platform is tailored to the industry-specific needs of customers, from faster onboarding of new employees, more efficient sales processes, and automation of knowledge work in all indirect process areas and manufacturing, to the elimination of manual knowledge documentation.
“In industry, expert knowledge determines quality and speed. If it is lost, costly productivity losses threaten. Blockbrain makes internal know-how from documents and team expertise quickly usable as Knowledge Bots, without complex programming and in compliance with GDPR. The team, practical benefits, and feedback from leading industrial companies convinced us. That’s why we are delighted to lead this round as lead investor,” says Benjamin Kleinschnitz, Senior Investment Manager at Alstin Capital.
When experienced employees leave a company, more is lost than just a position: expertise, decision-making logic, and established processes disappear and must be painstakingly rebuilt. Blockbrain offers a platform solution that enables companies to make this knowledge permanently available, augmentable, and automatable with AI agents.
With Blockbrain’s solution, digital knowledge twins can be created within just a few weeks. They store information from experts and specialists, map ways of thinking, decision-making logic, and methodological knowledge, and make it scalable as needed. These so-called Knowledge Bots then make the stored experiential knowledge permanently available across teams and locations. Existing customers such as Axel Frey, CEO of Seifert Logistics Group, report weekly time savings of up to 15% through the use of their digital twin.
Hallucinations and misinformation are also reportedly eliminated due to the technical architecture behind the agents.
“We invested in Blockbrain because they combine advanced AI technology with the highest standards of security, compliance, and reliability. Their platform delivers real value to companies, potentially serving as a catalyst for Europe to gain more power and resilience in an era of uncertainty. At 13books Capital, we believe Blockbrain is shaping the future of responsible AI in all critical and regulated sectors, from financial services to manufacturing and energy,” explains Meera Bissoondeeal, Principal at 13books Capital.
With the fresh capital, Blockbrain is investing specifically in further expanding the security, compliance, and governance of its platform. At the same time, the company is advancing the development of specialised knowledge and AI agents – including features such as a fallback mechanism for AI models to increase the availability and reliability of answers, as well as new agent and research workflows to automate knowledge building and research processes.
The company is expanding its presence in Europe and the UK and strengthening its team with Forward-Deployed AI Engineers – specialised experts who closely support companies in the introduction and use of AI agents and their integration into existing systems, either remotely or on-site.
Targeted investments are also being made in further developing the platform and researching new application areas around AI-supported knowledge management.
