Book Call With Gerrit 
We believe European enterprises deserve AI solutions that respect their data, their regulations, and their sovereignty.
Book Call With Gerrit Ironum is a product of LearnSlice UG (haftungsbeschränkt), founded in 2024 in Düsseldorf, Germany. What started as an AI-powered education platform quickly revealed a bigger opportunity: European businesses needed AI solutions that did not compromise on data privacy.
Every week, we spoke with companies who wanted to use AI but were blocked by GDPR concerns, vendor lock-in fears, and a lack of technical expertise. The big cloud providers offered power but not sovereignty. The open-source community offered freedom but not enterprise readiness.
Ironum bridges that gap. We combine open-source foundations with enterprise-grade deployment, wrapping everything in European compliance from the ground up. No data leaves the EU. No vendor lock-in. No compromises.
Founded in Düsseldorf, Germany
European-hosted infrastructure
Data transfers outside the EU
We exist to make enterprise AI accessible, compliant, and sovereign for European organizations. AI should amplify human capability, not compromise privacy, create dependencies, or export European data to foreign jurisdictions.
Creative technologist and web designer since the early 2000s with 20+ years of experience and 100+ projects shipped, from design systems and icon libraries to SaaS products and frontend tooling. Built LearnSlice, an AI-powered education platform, and AskMention, a Generative Engine Optimization tool. Founded Ironum to help European businesses deploy AI solutions that are private, customizable, and built to last.
Data privacy is not a feature. It is a fundamental right. Every architecture decision starts with the question: how do we protect the data?
We build on open-source technology because transparency breeds trust. No black boxes, no vendor lock-in, no hidden dependencies.
Europe needs its own AI infrastructure. We build it here, host it here, and keep it here, because sovereignty requires independence.
Enterprise AI should not require an AI team. We make complex technology accessible through clear interfaces, thorough documentation, and hands-on support.
