## About this market
Most of the public-sector work on this page is Microsoft and ServiceNow platform delivery run as a managed service, with operated AI systems beside it. The platform work is largely Irish: Storm Technology built citizen services on Dynamics 365 and Power Platform for Limerick City & County Council and case management for the Labour Court, Spanish Point Technologies built PAMS for the National Treatment Purchase Fund, live in 40 public and 18 private hospitals, and TEKenable's AI is a component, detecting patient-identifiable information in media uploaded to the training platform it built for the Royal College of Surgeons in Ireland. Version 1's Department of Social Protection work is a 2026 framework award, not yet a delivery.

The operated AI is narrower and better documented. Adnovum's Berna takes Gebäudeversicherung Bern's claim calls in parallel during storms at up to 2,700 a day, transcribing Swiss German dialect into structured claim files; Adnovum runs the managed service on Spitch's speech layer, and Berna covers storm and hail claims in German only. Pexon Consulting's speech documentation at Klinikum Landsberg am Lech, live since March 2025, pseudonymizes audio inside the hospital and had transcribed more than 1,300 consultations.

The sorting question is what the retainer pays for: operating an AI system, or maintaining the platform an AI feature may later sit on. For the first, ask what a successor contractor would receive at re-tender—call flows, the speech vendor contract, pseudonymization keys—and in whose tenant the audio sits. For the second, ask for a named AI system already in production on that platform, not the roadmap slide.

## Questions buyers ask

### How many AI agencies work with retainer on public sector?
21 agencies in our directory combine verified retainer client evidence with documented Public Sector work. The current top-ranked are Storm Technology, ontolux, Version 1 — ordered by depth of documented client evidence, then our editorial scoring (portfolio quality, credibility, completeness); placement is never paid.

### How much does an AI agency cost for public sector?
Published rates across this page's agencies run €45–175 per hour (median ~€108). Project totals depend on scope — the rate index at /rates breaks the computed bands down by region, country and team size.

### How is the retainer model verified?
Every agency here documents retainer work on its own site or in a published case study, describing the engagement structure rather than a service-list claim. We never infer the model from portfolio tone, so this list only contains agencies that operate retainer engagements deliberately.

### Can these agencies embed consultants with our team?
2 of the agencies on this page document an embedded / team-extension working model. See the team-extension page for the full verified list, or check the engagement chips on individual profiles.
