Ruben Vereecken is a Data & AI leader and hands-on technologist with 12 years of experience building product-led engineering teams and shipping high-impact AI systems. Currently leading Data & AI at Glass Health, he designed a clinical decision support agent on top of a 40M-article RAG corpus, blending deep research instincts from his PhD in AI with pragmatic startup delivery. He has a track record as founder, fractional CTO, and interim CTO—scaling teams from zero to product-market traction and prioritising lean, incremental value. An active open-source contributor, Ruben has improved infrastructure and protocol work across projects from tldr-pages to Pokémon GO protobufs and contributed localization and gamification work to CodeCombat. Based in London, he runs CTO Lunches to connect engineering leaders and advises early-stage ventures while still diving into code and reverse engineering problems himself. Outside work he balances intense focus with endurance—he’s an ex-PhD who runs beer marathons.
