Yves Peirsman is a co-founder and CTO with two decades of deep expertise in Natural Language Processing, blending academic research (KU Leuven, Stanford) with product-focused engineering at companies like Textkernel and Wolters Kluwer. He builds practical NLP systems across domains—finance, healthcare, e-commerce, publishing and mobility—currently applying AI to streamline compliance at Deontic. A prolific open-source contributor, his NLP models and educational notebooks (nlptown/nlp-notebooks) have been widely used and downloaded, with a focus on sentence similarity techniques and pretrained embeddings. Yves also founded NLP Town to help organizations operationalize state-of-the-art language models and organizes the Belgium NLP Meetup to connect practitioners. Beyond engineering, he writes fiction—multiple crime novels and a forthcoming literary novel—bringing an unusual creative perspective to language technology.
