## About this market
Industrial AI in Spain, as this page publishes it, sits above the machine rather than on it. QUANT AI Lab in Madrid carries the most plant-adjacent catalog: predictive maintenance and PPE detection sit among twenty-eight published use cases, each with its stack named, though every use case is anonymized and none carries a result. Plain Concepts, also in Madrid, works at enterprise platform scale on Azure, and its Nestlé work spans phishing-URL vision inspection, an MLOps platform and a governed generative-AI platform for employees, which is a manufacturer's corporate estate rather than its production line. NextAI in Valencia describes agents that run complete workflows across a company's own data, processes and tools, and names Alumet, a Spanish aluminum company, among its clients; its published case studies cover real estate, retail and compliance work, none of it on a factory floor.

So be precise about where your problem sits. Planning, forecasting, maintenance scheduling and the data estate around them are the work described here; line-side vision and control systems are not published as delivered work, and the Munich roster carries more of that. Ask each candidate for an engagement where the data came off equipment rather than out of a reporting database, and take a straight no as useful information. With QUANT AI Lab, ask which logo maps to which build. With Plain Concepts, confirm the Microsoft stack suits your IT organization before scoping, since nearly every published build lands on Azure. Plain Concepts' profile shows €85–130/hr and NextAI lists €70–150/hr; QUANT AI Lab publishes no rate, so get day rates by role in writing early.
