THE PROBLEM

Two Problems, One Cause

For European companies

Your competitors are shipping AI features monthly. Your DPO says no. Your legal team says no. GDPR says no. Promising pilots stall in compliance review.

For US companies serving the EU

Your EU customers are starting to ask about data sovereignty in 2026 RFPs. Your US AI stack falls under the CLOUD Act. Your sales cycle slows in EU procurement.

The shared root

Both problems need the same answer: AI built on EU-sovereign infrastructure, with GDPR and EU AI Act compliance documented from day one.

WHAT OUR CLIENTS SAY

Real Results. Real Businesses.

From AI search visibility to sovereign learning platforms, here is how European companies use Ironum.

GEO Optimisation

"Our competitors were getting recommended constantly and I couldn't figure out why. Our product was better, our site was faster. Turns out they had structured data and a stronger review footprint on the right platforms. The audit made it obvious. We fixed it in two weeks. Now we're in the recommendations alongside them."

LLM Fine-Tuning

"We integrated quiz-based AI platform across multiple teaching methods, from inverted classrooms to quiz-based homework. The software boosted student motivation and helped them pass exams more successfully. It adapts seamlessly to individual learning needs, which is exactly what modern higher education demands."

Chatbot Interfaces

"Our customers trust us with their data. When we needed AI-powered personalisation, we couldn't send student profiles to a US cloud. Ironum gave us a sovereign AI layer that runs entirely on European infrastructure. Our learners get a modern, personalised learning journey, and their data never leaves our control."
