About this list
Five agencies hold public-sector evidence on both axes—their client is a public body and the work serves the public function—which is the tightest definition of a government supplier this register applies. Dr. Mark Wernsdorfer's AMPEL runs across more than 1,500 beds at a university hospital, and DoppelCheck, a browser extension running local machine learning for real-time disinformation detection, was a finalist for the International Award for Innovation in media. Birds on Mars built Quantified Trees with the Federal Environment Ministry and ELIO for the Museum für Naturkunde. Adnovum runs voicebots for a cantonal building insurer and a cantonal road traffic office. DataNorth and ELCA cover Dutch and Swiss administration.
Two details separate suppliers who have done this from suppliers who describe it. First, local execution: DoppelCheck runs its model in the browser, and AMPEL runs inside hospital infrastructure, because in this sector where the inference happens is a governance decision rather than an engineering one. Second, the handover. Ask what the institution owns at the end and what it can operate without the supplier—public bodies live with their systems far longer than the contracts that built them.
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
5 agencies in our directory combine verified public-sector client evidence with documented Public Sector work. The current top-ranked are DataNorth AI, Adnovum, Dr. Mark Wernsdorfer — ordered by depth of documented client evidence, then our editorial scoring (portfolio quality, credibility, completeness); placement is never paid.
Each listed agency has at least two documented, named public-sector clients — published case studies or engagement descriptions our research actually read, with source URLs stored per client. Logo walls without published evidence carry no weight, which is what separates this list from self-declared directories.
