Zar Amrolia started off as a quant at JPMorgan in 1988 when he was in his mid-20s. He drifted into trading and sales, with stints at Credit Suisse and Goldman Sachs, rose to the head of currency trading at Deutsche Bank and eventually became co-chief of XTX Markets.

Amrolia will step down in early 2023. Soon to join as deputy CEO will be Hans Buehler — a quant from JPMorgan. “Life has come full circle,” Amrolia jokes.
