## About this market
Software and B2B buyers in Vienna are working with a thin roster, which is the honest framing: three agencies, and the useful distinctions are about scale and hosting rather than about capability tiers. agency28 builds self-hosted workflow automation and AI agents with the runtime kept inside the EU—relevant if your own customers ask where their data is processed. Dev House Austria has traded since 2012 and publishes named-client AI builds including BMW, working language-model integration into business software. Waterglass covers applied AI delivery for B2B clients. Blck Alpaca joins from the go-to-market side rather than the product, building agents and AI-search visibility for B2B firms.

The product questions apply here as they do anywhere: what does the feature cost per thousand invocations now versus at launch, how is quality regression caught when the underlying model updates, and what is the fallback when generation fails mid-session. None of these is exotic, and all three separate a shipped AI feature from a liability. If the answers are thin, the London and Stockholm SaaS pages carry deeper benches.
