## About this market
Software companies in Ljubljana get a compact page with one genuinely different option on it. Alpdev is the closest fit for most SaaS work — an OpenAI Select Partner whose references are platform builds and assistants integrated with CRM, telephony and ERP. Indigo Labs brings voice and vision components that a product embeds rather than bolts on. Abelium R&D is the outlier: a research house since 2009 whose value is the algorithm inside your product, not the product around it.

SaaS buyers should press on the questions that separate an AI feature from an AI liability. What does the feature cost per thousand invocations today against what it cost at launch, and what does that do to margin at ten times the volume? How is quality regression caught when a model provider ships an update you did not ask for, and does an evaluation harness exist to catch it or will a customer report it first? Then ask about handover — repository, infrastructure as code, evaluation set, runbook — because with teams this small the difference between a system you own and a system only they understand is the difference between an asset and a dependency.
