M47 is a Barcelona-based AI services company founded in 2018, operating at 51–200 employees with an engineering-focused org (27 active roles, all technical). The stack spans Python, PyTorch, scikit-learn, Keras, and spaCy — classical ML infrastructure — paired with FastAPI, Django, and cloud (AWS, GCP), indicating a services model that moves from model training to production APIs. Active projects center on voice assistants, multilingual NLP, and customer-experience AI products; pain points cluster around responsiveness, cross-language model accuracy, and test automation, suggesting the team is scaling model quality and deployment velocity rather than building new infrastructure.
