TietAI has raised €2.5M in seed funding to bring AI into the operational heart of hospitals
Our story

We didn't build TietAI because healthcare needed more AI. We built it because hospitals were drowning in disconnected systems — and patients were waiting.

I watched teams lose hours every week moving information between systems that should have already been connected. The data existed. The infrastructure to use it, didn't. That's why we built TietAI.

Clinical data should flow between systems, not get trapped in silos. Every integration we build opens a path that didn't exist before.

Finnish concept

Sisu

Extraordinary determination in the face of the seemingly impossible. Not recklessness: quiet, steady progress. That's how we approach every integration the industry assumes can't be done.
