## About this market
Software companies buying AI in Barcelona have four options and a wide quality spread. AlamedaDev is the engineering choice, with five published client-named cases across agents and retrieval systems. cronuts.digital productizes automation for growth and revenue teams, publishing three named-client cases against a much longer client list. Shymow and Konektor Group publish neither cases nor named clients, and are listed with that stated rather than implied.

SaaS buyers should press on the questions that separate an AI feature from an AI liability: what it costs per thousand invocations now against at launch, how quality regression is caught when the underlying model updates, and what happens when generation fails mid-session. Then ask about ownership—whose account the system runs in and what survives the engagement ending. The firms here with published engineering work can answer these from experience; the others would be answering them for the first time on your project.
