AlTi Global, Inc. has appointed Nancy Curtin as interim CEO and a member of its Board of Directors, effective immediately, as the firm positions itself for its next phase of expansion. 

Curtin, who currently serves as global CIO, succeeds Michael Tiedemann, who will remain involved in an advisory capacity to support the leadership transition. Since AlTi’s formation, Curtin has led a global investment team of more than 50 professionals, helping shape the firm’s strategy across wealth and institutional channels. 

Her appointment comes as the firm continues to scale its platform serving ultra-high-net-worth families, foundations and endowments. Prior to AlTi, Curtin held senior leadership roles at Alvarium Investments—where she served as CIO and head of investments prior to its merger into AlTi—as well as at Close Brothers Asset Management and Fortune Asset Management. Earlier in her career, she held senior roles at Schroders and Barings Asset Management and currently serves as chair of the board at DigitalBridge Group, Inc.. 

“As the Company continues to build a leading global wealth and investment platform for ultra-high-net-worth families, foundations, and endowments, the Board believes it is an appropriate moment to identify an executive to lead AlTi in its next phase of growth,” said Timothy Keaney. 

Curtin emphasized continuity and expansion in her new role. “Over the past several years, AlTi has sharpened its strategic focus while maintaining a relentless commitment to excellence within the ultra-high-net-worth space,” she said. “Given the strength of our institutional-quality platform, we will also continue to expand our offering to foundations and endowments globally.”
