# Jan Szilagyi

> Jan Szilagyi is the CEO and co-founder of Reflexivity (formerly Toggle AI), a New York fintech building zero-hallucination AI for investment analysis. He ran a $15 billion global macro book at the world's top hedge funds - Duquesne, Fortress, Lombard Odier - before deciding the tooling he wished he'd had didn't exist, so he built it. He earned the fastest Harvard Economics PhD on record (2.5 years) under Ken Rogoff, and his first backer was his old boss Stanley Druckenmiller.
