About this list
Ljubljana's B2B page is small studios publishing unusually plain project detail, and the useful distinction is how much of it describes AI in use. Indigo Labs publishes the scoping most agencies withhold—duration, team size, budget band and stack per project—from a two-month, one-engineer chatbot for the University of Ljubljana's mechanical engineering faculty to an ESG tool pairing Azure AI Document Intelligence with OpenAI, the latter described as an MVP in testing. Alpdev names every client and what it built: a lead-scoring model with a language-model intent score for Polfin, and a product assistant for Bent that links to real catalog entries through the ERP rather than generating answers, though no reference carries an outcome number. MS iHub names Henkel and Domel among its clients, but its one AI system described in checkable detail is a generator that wrote more than 15,000 product descriptions for an online tools store.
These are small teams, so the buying questions are about continuity rather than capability. Ask who will build the system and who will look after it in a year, whether the named reference is still running, and what the budget band on the project page covered. A firm that states scope before the contract is easier to hold to it afterward.

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.
