## About this market
Public-sector projects are judged by what left the building, because the administration runs what it bought. Merantix Momentum has run Hamburg's InnoTecHH innovation and governance process since 2022, with 120+ use cases evaluated in 2023, 19 in development and 8 scaled; its Federal Chancellery work ended as a proof of concept on a locally hosted Mixtral model handed over for integration, and its DZSF noise-barrier detector shipped as an open-source plugin. Fast Data Science trained the Information Commissioner's Office email classifier inside an isolated environment on data that could not be retained. Instituto de Ingeniería del Conocimiento's reservoir-inflow forecasting for Canal de Isabel II is implemented, while its SERMAS allergy-coding work is a pilot. Babel was awarded the governance and monitoring office of the Andalusia AI Center, covering model inventories and EU AI Act compliance.

For an administration buying a fixed-scope build, ask what form the handover took: an open-source release, a locally hosted model, a system with a named operator, or a proof of concept awaiting integration. Then ask who inside the organization runs it now; the curator notes several Merantix references are funded research consortia or feasibility studies. Read the tag against the evidence: Bismart's named public work for Barcelona de Serveis Municipals and Segittur is Power BI data integration, not a model; Mercury Labs' IfATE and MTC pages publish no metric, stack or live status; MS iHub's procurement-analysis platform is ongoing with no outcome stated; and Siili Solutions' production agent, Bobotin, runs at an insurer.

## Questions buyers ask

### How many AI agencies work with project-based on public sector?
33 agencies in our directory combine verified project-based client evidence with documented Public Sector work. The current top-ranked are Storm Technology, Merantix Momentum, ontolux — 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 €45–260 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 project-based model verified?
Every agency here documents project-based 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 project-based 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.
