German GenAI Startup Blockbrain Raises €17.5M Funding In Series A Round

The funding round was led by Alstin Capital and 13books Capital, with participation from HARTING Family Foundation. Existing investors Giesecke+Devrient Ventures, Landesbank Baden-Württemberg Ventures, and Mätch VC also increased their investment, bringing the company’s total funding to €23 million.

Founded in 2022, Blockbrain is an AI platform that empowers companies to securely digitize expertise, processes, and decision-making logic, making them accessible and actionable across the organization. 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).

“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.

Blockbrain’s mission is to address the shortage of skilled workers and structural inefficiencies in businesses through an intuitive, no-code AI platform, enabling internal know-how to be systematically captured, augmented, and automated.

By 2025, Blockbrain achieved a fivefold increase in revenue. Its customer base includes Roland Berger, Bosch & Bosch Rexroth, Kärcher, fischer, Harting, Eberspächer, Bardehle Pagenberg, CHG Meridian, Domcura, and Seifert Logistics Group.

“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.”

The platform is designed to meet industry-specific needs, supporting faster onboarding of new employees, streamlining sales processes, automating knowledge work across indirect processes and manufacturing, and eliminating the need for 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.
