Hedge fund Capula's CEO Steve Gregornik has left, as it moves into plush new Mayfair office

Steven Gregornik, a partner and chief executive officer at Capula Investment Management in London, has become the latest senior figure to depart from the $10.2bn hedge fund this year.

Gregornik has been at Capula since 2012, when he joined as chief operating officer, but was promoted to the CEO role 2013. David Gu, who was also co-chief investment officer, held the role at the time, but moved across to money management duties. Gregornik's departure was revealed on Companies House today, but the register suggests that he departed in late May.

Capula, a fixed income focused hedge fund set up by former J.P. Morgan trader Yan Huo and co-chief executive Masao Asai in 2005, has been losing senior staff throughout this year. In June, David Gu, co-CIO and partner at Capula, left the hedge fund to join Adarga Limited, a tech firm that uses machine learning and cognitive computing to help clients delve into reams of data. Meanwhile, Thorkild Juncker, its co-head of investor relations, also departed in July.

It did, however, hire Fredrik Gentzel from Deutsche Bank as its chief operating officer in February.

Despite the departures, Capula does not appear to be struggling. While a number of high profile hedge funds have retreated from expensive Mayfair offices in recent months to cut costs, Capula has just moved into a plush new 12,000 square foot office across three floors at a new development in 7 Clarges St, Mayfair - a stone's throw away from Green Park.

According to Oktra, the designer who worked on the building, the look was "a sophisticated yet simplistic design"

"We converted the second floor into an open plan trading floor with meeting rooms. On the third floor we designed a main reception area, with a five meter long patterned sprayed metal desk using overlaid cutting sheets to form a sculptural piece. On the sixth floor we built a complete catering kitchen”, it said.
