The HTX Take #
This topic is at the heart of what we build at HTX. The technology discussed here — whether it’s about AI agents, language models, or document processing — represents exactly the kind of capability that European businesses need, but deployed on their own terms.
The challenge isn’t whether this technology works. It does. The challenge is deploying it without sending your company data to US servers, without violating GDPR, and without creating vendor dependencies you can’t escape.
That’s why we built ORCA — a private enterprise chatbot that brings these capabilities to your infrastructure. Same power as ChatGPT, but your data never leaves your perimeter. No per-user pricing, no data leakage, no compliance headaches.

FAQ
How is AI transforming European businesses?
AI is enabling businesses to automate document processing, enhance decision-making, and unlock insights from their data. However, European businesses face unique challenges: GDPR compliance, AI Act requirements, and data sovereignty concerns. Private AI solutions — like HTX's PRISMA stack — address all three while delivering the same capabilities as cloud AI.
What's the first step to adopting AI in my company?
