Marius Cobzarenco is a senior AI research leader and entrepreneur with 13 years of experience building production ML systems, currently Senior Director of AI Research at UiPath after co-founding and serving as CTO of re:infer. He led product, engineering and research teams that commercialised low-data NLP models for automating knowledge-worker tasks and raised $11M before re:infer’s acquisition. Technically hands-on, he combines a PhD in machine learning with practical systems work—from recommender backends at Last.fm to Rust terminal tooling contributions that show attention to low-level reliability. His research roots in deterministic approximate Bayesian methods inform a pragmatic approach to building agents that interact with software via UI and natural language. Equally comfortable in fundraising, sales and deep technical execution, he hires and mentors high-performing teams to turn research into scalable products.
