Hiflylabs describes dedicated data-science resources deployed into a client's data commercialization unit for more than three years, beside named LLM builds such as Billingo's text-to-SQL and RAG agent, taken from proof of concept through pilot to full production. Grepton places developers inside client Business Central teams and keeps supporting the ERP afterward with fixes, new features and version updates; its named AI system is a Teams chat agent for ANDA Present Group that answers from SharePoint documents within existing permission groups. Lexunit makes software engineers available to partners as IT outsourcing, and Hyundai Technologies Center Hungary gives a named testimonial on a data-science engagement with no case study behind it. R-Szoft is a software house whose named work is Java, Angular and Go development, including a B2B ordering platform for Xella taken over from a previous team. For a buyer in Budapest the question to sort on is what your embedded people will be extending. A Dynamics estate, a data platform and a custom web system each need a different bench, and the AI work on this page follows the stack each firm already runs. Ask which engineers would sit in your team, whether they have shipped a model or only the system around it, and who keeps the institutional knowledge when the placement ends. The curator's watch-outs repeat one point across these listings: ask for a named reference running an AI system in production today. ## Questions buyers ask ### How many AI agencies work with team extension in Budapest? 4 agencies in our directory combine verified team extension client evidence with a Budapest base. The current top-ranked are Lexunit, Hiflylabs, R-Szoft — 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 in Budapest? Published rates across this page's agencies run €20–85 per hour (median ~€48). Project totals depend on scope — the rate index at /rates breaks the computed bands down by region, country and team size. ### How is the team extension model verified? Every agency here documents team extension 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 team extension engagements deliberately. --- Source: AIAgencies.eu — the curated register of European AI agencies.
