Talent Exodus at Viking Global: How Savina Boyadjieva's Move Reflects Broader Leadership Shake-Up

Viking Global, the $55 billion hedge fund managed by billionaire Andreas Halvorsen, is experiencing a significant wave of senior executive departures. The most recent shift came when Savina Boyadjieva, who previously headed the firm’s investor relations, joined Joshua Kushner’s Thrive Capital as a partner. This departure exemplifies a growing trend within one of the industry’s most prominent Tiger Cub funds—a group of elite hedge funds that trace their origins to Julian Robertson’s Tiger Management.

Stuart Brown’s Departure Signals Continuing Leadership Transition

Trading chief Stuart Brown is stepping away from Viking Global to take a break from his career, marking another significant change in the fund’s executive structure. Brown, who has spent nearly two decades overseeing the firm’s trading operations since joining from Credit Suisse’s corporate credit sales division, will remain during a transition period to facilitate a smooth handover. While his exact departure date hasn’t been finalized, his exit adds to a growing roster of leadership changes within the organization.

The Pattern of Senior Executive Departures

The challenges facing Viking Global extend well beyond Brown’s departure. In August 2024, Ning Jin, the fund’s Chief Investment Officer, left to launch his own fund, Avantyr Capital. Operationally, Andrew Genser, who served as general counsel, joined Avala Global—a fund led by former Viking portfolio manager Divya Nettimi—during the summer of 2025. Kevin Curtis, who previously managed recruiting efforts, moved to Bobby Jain’s fund in September 2025. Each departure represents not just a loss of experienced talent but also institutional knowledge and strategic direction.

The exit of Savina Boyadjieva to Thrive Capital underscores how even support-side leadership—roles critical for fundraising and stakeholder management—is being drawn away to competing opportunities in the investment ecosystem. These moves collectively suggest that Viking Global is facing a talent retention challenge that extends across its investment, operational, and business development divisions.

Investment Performance and Strategy Under Pressure

The timing of these departures comes amid challenges in Viking Global’s investment performance. Last year, the fund delivered an 8.6% return, falling short of the S&P 500’s performance—a notable gap for a hedge fund of this caliber. The fund’s approach differs from some Tiger Cub peers, with relatively lower exposure to technology stocks compared to competitors like Tiger Global, Coatue, Lone Pine, D1, and Maverick.

This positioning can prove advantageous in certain market environments, as demonstrated in 2022, but it also means the fund may miss significant gains when major technology companies like Nvidia, Amazon, and Microsoft fuel broader market rallies. With key decision-makers such as Ning Jin now departed, the continuity of Viking Global’s investment philosophy and execution faces questions. The loss of experienced talent across trading, investment management, and investor relations could create operational friction precisely when the firm needs stability.

Currently employing 275 people, Viking Global must navigate both the immediate challenges of backfilling critical roles and the longer-term question of whether the departing executives’ moves signal deeper concerns about the firm’s strategic direction and competitive positioning within the elite hedge fund landscape.
