Arctos, a private investment firm that provides bespoke growth and liquidity solutions to sports franchises (Arctos Sports) and alternative asset managers (Arctos Keystone), today announced the promotion of Alastair Seaman and the appointment of Brian Lafemina as Partners, reflecting continued investment in the firm’s leadership and global platform.

Mr. Seaman is being promoted to Partner after nearly five years of significant contributions to the firm. Prior to joining Arctos, he held investing roles at Goldman Sachs Asset Management and HarbourVest Partners, among others. He has played an instrumental role in building Arctos’ presence in Europe and will continue to lead investment sourcing, diligence, and portfolio management across the international sports strategy.

Mr. Lafemina, who joined Arctos as an Operating Partner in April 2024, now steps into a full-time Partner role. A seasoned executive with more than three decades of experience in sports operations, leadership, and revenue generation — including roles with LA 2028, the National Football League (NFL), and The Madison Square Garden Company — he has already made a meaningful impact by enhancing Arctos’ value creation capabilities and acting as a trusted advisor to owners and operators across professional sports teams and franchises.

“Alastair and Brian exemplify the type of thoughtful, collaborative leadership that defines Arctos,” said Doc O’Connor, Co-Founder and Managing Partner at Arctos. “Each has demonstrated a steadfast commitment to our mission and our partners. Their integrity, strategic vision, and ability to drive results make them invaluable stewards of our platform as we continue to grow.”
