## About this market
Healthcare here divides at the patient-data line, and the documented work sits on both sides of it. Pexon Consulting's speech documentation at Klinikum Landsberg am Lech has been live since March 2025: medical terms are recognized and written straight into the hospital information system, audio is processed and pseudonymized inside the hospital, more than 1,300 consultations had been transcribed and documentation effort was cut by more than 90 percent. Hybrid Heroes built DIRECT, an e-mental-health platform with exercises and questionnaires, for Freie Universität Berlin with the Swiss Red Cross, and punktum digital put early disease detection inside DiaperID's infant health app; neither write-up publishes an outcome. Limebit runs machine-learning models in production for statutory health insurers on the eRezept program, payer data rather than a care setting. Other work operates around care rather than inside it. OstraconAI's Rex reference-search assistant has been used by Nordic Healthcare Group's sales team through Teams since August 2025, and its Gosta Labs outreach retainer reached oncologists for 198 replies and 62 opportunities. Inbold has been Ambu's single production partner for instructions-for-use since 2016, 161 instruction documents across 27 languages, documentation work with no AI described. Bismart integrated data from 46 Sanitas Mayores centers into Azure SQL with Power BI reporting above it. G+D Netcetera's RiSIC classifies health-insurance claims for fraud and waste, in an expertise article with no named sponsor. wukonig.com carries the healthcare tag without a healthcare engagement in its published work.

Ask first whether the retainer touches patient data or commercial data, because the operating obligations differ. A clinical system needs to say where audio and records are processed and who holds the pseudonymization key; Pexon's case answers that in print. A commercial or documentation retainer needs measured usage figures, which the curator notes OstraconAI's healthcare cases do not yet publish.

## Questions buyers ask

### How many AI agencies work with retainer on healthcare?
20 agencies in our directory combine verified retainer client evidence with documented Healthcare work. The current top-ranked are Square Root Solutions, OstraconAI, Hybrid Heroes — 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 healthcare?
Published rates across this page's agencies run €20–400 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?
3 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.
