About this list
Six agencies hold both financial-services and public-sector evidence, and the overlap is not an accident: central banks, cantonal insurers and state-owned financial bodies buy AI under the strictest documentation regimes in the market. Squirro works both sides directly, with the European Central Bank alongside Standard Chartered and OCBC. Zühlke built VP Bank's investment recommender with compliance filtering in the architecture, and its public work reaches the NHS and National Grid ESO. Adnovum names UBS and PostFinance while running voicebots for two cantonal bodies. Visium, Unit8 and ELCA complete the roster across Swiss federal, pharma and private-banking work.
What these buyers share is that the evidence package matters as much as the system. Model documentation, monitoring design, the human-oversight arrangement, and a clear account of behavior under uncertainty are the deliverables a supervisor or an auditor will actually read. Ask for the versions produced on a prior engagement rather than a description of the approach—and ask who signed them, because in this sector the signature is the part that took the longest to earn.
Expert Insight
Why FinTech experience matters
Regulatory literacy—Fraud detection, transaction monitoring, and credit models operate under supervisory expectations for model risk management, and creditworthiness scoring is a high-risk category under the EU AI Act. Specialists design the documentation, logging, and human-oversight layer from day one; generalists discover it exists when your compliance team blocks the release
False-positive economics—A fraud model is judged by its false-positive rate, because every false alarm is a blocked customer and a manual review costing real money. Specialists tune for the operational cost curve, not headline accuracy—a model that's 99% accurate can still bury your operations team in alerts
Legacy integration—The model is the easy part; connecting it to a core banking system, a payments switch, and a case-management tool built in 2008 is the project. Firms with financial-services experience quote the integration honestly instead of discovering it in month three
Vendor-risk survival—Banks and insurers put suppliers through outsourcing reviews, security questionnaires, and audit-rights negotiations that stall unprepared vendors for months. Specialists arrive with the documentation pack ready, which shortens procurement instead of stalling it
Frequently asked questions
6 agencies in our directory combine verified public-sector client evidence with documented FinTech work. The current top-ranked are Zühlke, Unit8, Visium — 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.
