Summary
👤
Senior🎓
Top SchoolValentin Hartmann is an AI research scientist and entrepreneur in Lausanne with a decade of experience at the intersection of machine learning, privacy, and applied mathematics. He is co-founder and CEO of Timely, building language-learning products, while leading research at Xent Labs on novel reinforcement-learning approaches for more generally intelligent LLMs. Valentin completed a PhD at EPFL focused on privacy-preserving ML—publishing and producing practical systems in differential privacy, federated learning and distribution inference—and has a track record of shipping research into production (e.g., a federated SVM deployed with the Cliqz browser). His earlier work includes efficient algorithms for Wasserstein distances that were integrated into the R transport package, reflecting strong numerical and C++ implementation skills alongside formal math training from TUM and Göttingen. He blends rigorous academic methods with startup velocity, often turning theoretical ideas into working infrastructure.
