Nenna AI

What Nenna AI does

Nenna AI (legal entity: nenna.ai GmbH) is a Berlin-based, venture-backed startup founded in 2023 that sells an AI privacy and enablement platform targeting European enterprises and public-sector organizations in regulated industries. The company's core product wraps leading third-party AI models — including OpenAI, Anthropic Claude, Google Gemini, Mistral, Llama, Microsoft Copilot, and Perplexity — with proprietary automatic data masking and demasking, so that sensitive personal data, attorney-client privileged material, banking-secrecy information, and other regulated inputs never reach the underlying model providers in clear text. The platform is composed of NENNA Chat (a unified enterprise AI interface with knowledge bases, prompt libraries, and agentic workflows), NENNA Watch (a browser extension that monitors and controls shadow AI usage across 300+ external services), and NENNA Shield (a Privacy API for embedding real-time masking into existing AI processes). All workloads run on European cloud infrastructure provided by Exoscale, hosted in Frankfurt, Germany, with no data transfer to third countries.

The company monetizes through a three-tier SaaS subscription (TEAM up to 20 users, DEPARTMENT up to 200 users, ENTERPRISE unlimited) with contact-based quote pricing, supplemented by usage-based fair-use limits and professional services such as onboarding, rollout support, and dedicated customer success. Compliance is positioned as the central value proposition: the platform is built for GDPR, the EU AI Act, DORA, German banking secrecy, and — distinctively for the legal vertical — BRAO (§43a, §43e) and §203 StGB. The infrastructure stack holds ISO 27001, ISO 27017, ISO 27018, TISAX, and BSI C5 certifications, and the company carries the BITMi 'Software hosted in Germany' quality seal. Go-to-market is sales-led and event-driven, with named customers spanning law firms (KI Proof), public sector (Wirtschaftsförderung Münster), consulting (Ralf Ressmann, eye-level consulting), and agencies.

Operationally, Nenna is early-stage but well-capitalized for its size: it raised an angel round in October 2024, a €1M+ seed in January 2026 co-led by IBB Ventures and dfv Venture, and additional seed funding in May 2026 from Zurich-based Groundshift. In April 2026 it was selected for Gateway Factory's 'Ready to Scale 2026' accelerator, and in May 2026 it entered InsurLab Germany's Collaborator Batch 2026 to co-develop insurance-specific solutions. The team is approximately 7–10 people led by co-CEOs Alexander Siebert and Lars Moll (the latter formerly CEO of BILD-Group), with Dr. Max Flöttmann as CTO and Florian Spengler as Head of Business Development. The company has accumulated 50+ B2B customers in the first three months post-launch and has been recognized with the ATHENE Startup Award (Top 3 Cybersecurity Startup in DACH, 2025), the GITEX Europe AI Everything Award (2025), and Best Legal Tech Startup at the German Legal Tech Summit (2025).

Core offering

Nenna AI provides an enterprise AI privacy platform that enables GDPR-compliant use of leading large language models through automatic data masking and demasking. The platform combines a secure AI chat interface, a browser extension, and a privacy API, all backed by EU-hosted infrastructure to keep sensitive data inside regulated jurisdictions.

Product overview

NENNA.AI is an AI Enablement Platform offering a unified, secure AI infrastructure for enterprises in Europe. The platform is built around three core products: NENNA.AI Chat (a standalone enterprise AI platform providing access to all major AI models through a single secure interface), NENNA.AI Watch (a browser extension for monitoring and controlling shadow AI usage across 300+ external services), and NENNA.AI Shield (a Privacy API for embedding real-time data masking into custom AI processes). The platform uses automatic data masking technology to protect sensitive information in prompts and documents before they reach AI models, enabling GDPR, EU AI Act, and BRAO-compliant AI usage. The three products scale through three pricing tiers — Team (up to 20 users), Department (up to 200 users with SSO and rollout support), and Enterprise (unlimited users with on-device models, Agentic AI integration, audit storage, and dedicated CSM). All solutions run on 100% EU-hosted infrastructure via Exoscale, ensuring full data sovereignty.

Direct peers

• Skyflow: Data privacy vault with PII redaction and zero-trust architecture for AI and analytics. Targets regulated industries (financial services, healthcare) similarly to Nenna, with a comparable data-masking-before-AI approach.
• Credal AI: Provides AI data security for enterprises using LLMs, with masking and governance features directly comparable to Nenna Shield and NENNA Chat's privacy layer for regulated industries.
• Protecto: AI data privacy platform specifically focused on masking sensitive information before it reaches LLMs — directly comparable to Nenna Shield's Privacy API approach for enterprise AI processes.
• Securiti: Enterprise AI security, data privacy, and governance platform. Competes with Nenna in the AI GRC space, particularly for organizations needing data masking, consent management, and AI governance for regulated data.
• PrivateAI: Direct competitor offering PII redaction and de-identification for AI workloads — the same core capability Nenna offers via NENNA Shield and NENNA Chat's automatic data masking. Both target regulated enterprises that need to safely use LLMs with sensitive data.
• Concentric AI: AI-driven data security and data access governance. Overlaps with Nenna Watch's shadow-AI detection and data classification capabilities for enterprise compliance use cases.

Broad incumbents

• Microsoft Purview: Broad incumbent data governance and compliance platform bundled into Microsoft's enterprise stack. Competes at the AI governance / DLP layer and serves the same enterprise compliance buyer, but as part of a much wider portfolio including Copilot compliance.
• Collibra: Enterprise data intelligence and governance platform. Overlaps with Nenna at the data-governance and AI-compliance layer for large regulated enterprises, though it is broader and less AI-model focused.
• Google Cloud DLP: Broad incumbent cloud DLP offering from Google that competes at the data-masking/classification layer feeding into Vertex AI and Gemini. Less specialized for European regulatory verticals than Nenna.
• OneTrust: Broad incumbent privacy, security, and governance platform with AI governance capabilities. Competes for the same compliance-driven enterprise buyer as Nenna but addresses a wider privacy program rather than AI-wrapper specialization.
