AI engineering from Frankfurt
Looking for an AI agency in Frankfurt?
appDev isn't an agency — it's a software house in Frankfurt that builds production AI solutions and integrates them into your systems. At a fixed price, with EU hosting, and with a hand-over of the source code. If that's exactly what you expect from an AI agency, you're in the right place.
The difference
What we do differently.
Engineering, not consulting
What you end up with is working software inside your systems, not a slide deck. Analysis and design are the way to get there, not the deliverable.
A fixed price, not an open time budget
You know what the result costs before you start. The fixed price applies to a clearly described scope.
Clean hand-over, not a black box
You get the full source code and stay independent. No lock-in, free to switch at any time.

FAQ
Frequently asked questions about AI agencies in Frankfurt

The AI Discovery costs €1,900 and is fully creditable. The pilot starts from €39,000. You'll find the detailed breakdown on the costs page.
