Spencer Stuart Forms Long-Term Alliance with ONYX
November 12, 2025 – Spencer Stuart has inked a new long-term strategic partnership with ONYX, an invitation-only membership network of recently retired and longer-tenured CEOs, two-thirds of whom have led Fortune 500 companies and who collectively sit on over 400 corporate boards. Spencer Stuart made a minority investment in ONYX and will become its exclusive partner for leadership, talent and human capital programs.
“Spencer Stuart advises at the intersection of strategy and leadership, and this converges with the platform ONYX has created for their membership,” said Jordan Brugg, chief executive officer of Spencer Stuart. “We’re looking forward to partnering with the ONYX community to further our shared commitment to advancing the insights of the world’s most influential leaders.”
“Partnering with Spencer Stuart marks a defining moment for ONYX,” said Rick Smith, founder of ONYX. “Their global reach and deep leadership insights amplify our mission to elevate the world’s most influential executives. Together, we’re unlocking a new era of strategic growth, legacy-building and transformative impact across the ONYX ecosystem and around the world.”
Privately held since 1956, Spencer Stuart focuses on delivering knowledge, insight, and results through the collaborative efforts of a team of search professionals — now spanning 56 offices, 30 countries, and more than 50 practice specialties. The firm helps boards and leaders address their leadership needs in areas such as senior-level executive search, board recruitment, board effectiveness, succession planning, in-depth senior management assessment and many other facets of organizational effectiveness.
With a membership that includes many of the most respected current and recent Fortune 500 CEOs and their peers, ONYX offers a rarefied space for bold dialogue, strategic insight, and enduring legacy. “More than a community, ONYX is a movement — uniting CEOs, founders, and iconic changemakers who are redefining what it means to lead with purpose, influence, and imagination,” the organization said.
