NENNA.AI secures seed funding for European enterprises to use AI safely
21.05.2026
ZURICH, 26 May 2026 -- NENNA AI, a Berlin-based AI privacy platform, has joined the Groundshift portfolio. The company, which was initially backed by angel investors and completed a seed round led by IBB Ventures and DFV Mediengruppe at the end of 2025, enables enterprises to use any foundation model without disclosing sensitive data to the respective model providers.
NENNA Chat serves as a complete, standalone enterprise AI platform-comparable to Google Gemini Enterprise or Claude for Business, but with a fundamental difference: it delivers all top-tier AI models (Claude, OpenAI, Gemini, Mistral, and open-source alternatives) through a single, secure European interface where sensitive data never reaches external providers. Rather than forcing organizations to choose between competing model ecosystems, NENNA becomes the central AI infrastructure for all enterprise AI usage-combining secure model access, custom knowledge bases, agentic workflows, and privacy-by-design architecture. NENNA Watch extends this control to shadow AI usage across 300+ external services, while NENNA Shield embeds the same protection into custom AI processes via API – all from EU-hosted infrastructure that meets the strictest regulatory requirements.
“We built NENNA because the privacy problem in AI is structural. The moment a prompt reaches an external model provider, control is lost - no matter how strong their security promises are. European enterprises, especially in regulated sectors, can't accept that risk. They need banking secrecy, professional confidentiality, DORA compliance. But they also can't afford to wait while competitors leverage AI. The only solution is architectural: strip sensitive data before it leaves the enterprise perimeter, processed by an independent party the organization trusts precisely because we're not the model provider. That's what NENNA does - it removes the forced choice between innovation and compliance..” – Alexander Siebert, Co-CEO, NENNA AI
“European enterprises are simultaneously the most eager AI adopters and the most restricted. That tension creates a massive market opportunity. NENNA doesn't just address GDPR - it solves the deeper problem for banks, insurers, law firms, and public sector organizations that face sector-specific regulations far stricter than general data protection laws. These organizations represent trillions in economic value and have been effectively locked out of the AI revolution. NENNA's architecture unlocks that market by making data exposure structurally impossible, not just contractually prohibited. The team's +25 years of NLP specialization and their commercial traction in the most demanding sectors convinced us they will own the enterprise AI privacy layer in Europe.” – Alexandre Moreillon, Investment Director, Groundshift
Financial services is a central use case for NENNA AI, not an adjacent one. Banks, insurance companies, and regulated financial institutions face the sharpest version of the AI-versus-privacy tension: banking secrecy, DORA, and supervisory outsourcing requirements make them the most restricted AI adopters and, at the same time, the most eager. NENNA’s compliance-native architecture and European-hosted infrastructure are built for exactly this environment, which is why Groundshift, as a firm focused on B2B fintech and enterprise software for financial institutions, selected NENNA AI as a portfolio company.
