Who we are

Our story

OneChronos was founded by portfolio managers, traders, and technologists with backgrounds in market design who saw capital markets growing more complex, but not more sophisticated. While other marketplaces evolved, financial markets still relied on centuries-old approaches to matching buyers and sellers.

A Y Combinator alum, OneChronos is backed by Addition, BoxGroup, and Green Visor and headquartered in SoHo, New York City.
