Summary
The departures occur within a broader context of significant organizational change at the hedge fund. In September 2024, Brevan Howard appointed Mike Sanders as its new chief technology officer, recruiting him from JPMorgan. Sanders has since hired Tim Mace from Man Group as head of AI in late 2024, signaling aggressive investment in artificial intelligence capabilities alongside the technology infrastructure overhaul. The fund declined to comment on Russell's departure or provide rationale for the other exits, and Russell himself did not respond to requests for comment.
Brevan Howard's headcount trajectory underscores the technology focus underlying recent departures. The firm currently employs 1,050 people and manages 145 portfolio managers, according to its website. In contrast, 2019 figures showed only 150 employees and 30 portfolio managers, suggesting that the majority of new hires over the past five years have been technology-focused personnel. This substantial expansion in the technology function, combined with the Lodestar project's repatriation of systems from external vendors, indicates a strategic shift toward building internal technological capabilities—a transition that may have contributed to the documented departures of established technologists.
