About this list
The agencies here carry verified B2B evidence and list public-sector work, and the strongest of them pair the two, which is the combination institutions usually want—a supplier who is commercially proven but has also worked inside public constraints. dida's anomaly detection for Deutsche Bahn's Digitale Schiene automated-driving program pairs a fine-tuned MonoViT depth model with segmentation, and it built convective-cloud detection for the Deutscher Wetterdienst. ML6 and Faculty bring the deepest published outcomes, at the National Cyber Security Centre and the NHS respectively. Amsterdam Data Collective works inside the European Central Bank, Adnovum runs cantonal voicebots, and Lautmaler, DataNorth, AI Sisters and ELCA work the same territory across Europe. Merantix Momentum adds a Hamburg innovation program that has taken eight AI use cases to scale and a noise-barrier detector for Germany's rail research center, released as an open-source plugin. Public-sector depth varies more than the tags suggest: for some firms here the public engagement on record is data-platform or advisory work rather than an AI system, so read the card before assuming one.
Public-sector work rewards a different kind of due diligence than commercial work. The technical question is usually the easy one; the hard ones are where the data may sit, who holds the audit obligation, and what the supplier is contractually required to hand over at the end. Ask for a redacted deliverable from a prior public engagement. Firms that have done this before produce one; firms that have not will offer an architecture diagram instead.

Expert Insight
Why Public Sector experience matters
Procurement fluency—Tender rules, framework agreements, and evaluation criteria shape what can be bought and how. Specialists write compliant bids and structure engagements to fit thresholds; agencies new to public buying lose months learning the process on your calendar
AI Act depth where it bites hardest—Many public-sector uses sit in the EU AI Act's high-risk tier, with risk-management, logging, human-oversight, and registration duties. Specialists deliver the documentation as a work product, not a promise
Explainability as an acceptance criterion—Automated decisions touching citizens must be explainable to the citizen, the caseworker, and eventually an auditor. Specialists design plain-language explanation into the system; retrofitting it after a complaint is the expensive version
Accountability-grade delivery—Public projects end up in audit reports. Specialists document decisions, data sources, and model changes to the standard an oversight body applies, and they design human handoff into every citizen-facing flow rather than treating it as a failure state
Frequently asked questions
