What EU data residency really means for AI development

“GDPR-compliant” on a pricing page and actual EU data residency are different things. Here is what to check when you build software with AI — and how XAIO answers each question.

When your team builds with an AI platform, three kinds of data flow through it: your code and prompts, your business documents (specs, screenshots, uploads), and — once the app is live — your customers’ data. For a European company, where each of these is processed and stored is not a detail; it decides whether your own GDPR story holds.

The questions to ask any AI development vendor

  • Where does the generated application run — which region hosts the app, its database and its files?
  • Where do my prompts, documents and code live at rest?
  • Is the vendor itself the processor, and does it offer a DPA and a public list of sub-processors?
  • Can I take the code and run it on my own infrastructure if requirements change?

How XAIO answers them

XAIO is built in Vienna and operates with EU data residency at its core: projects and the applications you publish are hosted in the EU, and the platform is GDPR-native by design — with a DPA and a public sub-processor list as part of the product, not paperwork you have to request.

And because everything XAIO generates is standard, exportable code, the residency question has a final backstop: if your requirements ever demand it, you can take the application — frontend, backend, database schema — and run it on infrastructure you control. Data residency you can exit is the only kind worth relying on.
