In 2023, Tudor Achim co-founded Harmonic with Vlad Tenev to build the world's most advanced reasoning engine. Combining formal verification with informal reasoning, Harmonic’s formal reasoning model, Aristotle, achieved gold-medal-equivalent performance on the 2025 International Mathematical Olympiad problems. Aristotle integrates three main components: a Lean proof search system, an informal reasoning system that generates and formalizes lemmas, and a dedicated geometry solver.

Achim is also the Co-Founder and former CTO of Helm.ai. He holds a B.S. in Computer Science from Carnegie Mellon University and was a PhD Candidate in Computer Science at Stanford University.
