Summary
Citadel was founded in 1990 by Kenneth C. Griffin and is described in company profile listings as an American multinational hedge fund and financial services company with more than $77 billion in assets. Griffin leads the firm as founder, CEO and co-chief investment officer. The firm's leadership page lists Umesh Subramanian in the chief technology officer role, with responsibility for technology innovation and infrastructure. Because that listing is undated, it is unclear whether it describes the role before or after the reported appointment.
Technology has become a larger focus for large systematic and multistrategy managers, which compete on execution speed, data infrastructure and engineering talent. A CTO hire from a major technology company is consistent with that trend, though the source material does not state the firm's specific strategic objectives for the appointment.
