About this list
What these firms have in common is that the AI ends up inside an operating system rather than beside it. Dmlab's energy platform for Central Energy Trade Hungary Group forecasts solar output and customer demand, trades on the power exchange against its own forecasts, and issues the invoices. Lexunit's machine-vision line identifies the box, counts the parts and drives an OK indicator at the workstation, built to run on-premise with no internet connection. Hiflylabs put a text-to-SQL and retrieval agent into production inside Billingo's own product, with prompt anonymization in the path. Neuron Solutions is the exception on this page and a useful one: its record is mostly workshops and readiness advisory, with a drawing-recognition system for Knorr-Bremse as the built exhibit.
That shape sets the buying questions. Ask what happens when the model is unavailable, because a forecast feeding an automated trade and a vision model gating a production line both need a defined fallback. Ask where inference runs, since on-premise and cloud carry different answers on latency, cost and data residency, and two of the systems above were built for the constrained case. Then ask what the retraining cadence is and who owns it—operational models drift against a changing process, and a Hungarian B2B engagement priced for a small team can leave that question unassigned.

Expert Insight
Why B2B fit matters
B2B AI lives inside operational systems, so integration experience is delivery experience—an agency that has shipped into an ERP or a ticketing queue has already fought the battles your project will fight.
Operational outcomes are checkable in a way marketing outcomes are not: handle time, error rate and hours removed either moved or they did not, and the strongest agencies here publish those numbers.
The internal business case matters—an agency whose case studies quantify results gives your sponsor the numbers to defend the budget with.
Frequently asked questions
4 agencies in our directory combine verified B2B client evidence with a Budapest base. The current top-ranked are Lexunit, Hiflylabs, Neuron Solutions — ordered by depth of documented client evidence, then our editorial scoring (portfolio quality, credibility, completeness); placement is never paid.
Published rates across this page's agencies run €45–130 per hour (median ~€86). Project totals depend on scope — the rate index at /rates breaks the computed bands down by region, country and team size.
Each listed agency has at least two documented, named B2B 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.
