## About this market
Custom AI development in Spain is bought mostly from established software and data houses that added AI to an existing practice, not from AI-native studios. Plain Concepts has built since 2006 and works Azure-native across machine learning, MLOps and generative systems; Paradigma Digital engineers cloud-native data platforms for large Spanish enterprises; Sngular delivers at group scale across finance, retail, telecom and public-sector work; Bosonit covers data strategy through to generative AI. Damavis is narrower and more technical, a big-data studio building data lakes, models and real-time pipelines. QUANT AI Lab is the most specific about method anywhere on this page, publishing builds that name SageMaker, Hugging Face, TensorFlow, Airflow, LangChain, FAISS and pgmpy—an engineering catalog rather than a marketing one, though the clients behind it stay anonymized. Barcelona's contribution is smaller and product-shaped, AlamedaDev, Conectia, Bismart and Datarmony among it, and Anadea has been shipping software from Alicante since 2000.

Two screens matter more here than elsewhere. The first is where the engineers actually sit: Damavis works from Madrid and Palma, Bosonit from Madrid and Logroño, QUANT AI Lab from Madrid with offices in Paris, Bordeaux and London, and Anadea and Tensorway from Alicante. A Madrid address on the proposal does not settle which city writes the code, and that answer decides your meeting hours. The second is stack specificity, which varies widely here, from published library names to descriptions carrying no architecture at all. Ask which models, infrastructure and evaluation the documented work used, and what your own team could run after handover. Published bands stretch from €20-40 to €85-130; many entries show nothing, so scope in days and seniority rather than in headline rates.
