AlTi Global, a global wealth and investment partner to families, foundations and institutions, has announced the appointment of Nancy Curtin as the interim Chief Executive Officer (CEO) and promoted her to its Board of Directors.
“Ms. Curtin is a member of the executive leadership team and serves as Global Chief Investment Officer of AlTi. She succeeds Michael Tiedemann, who will remain available in an advisory capacity to support the transition,” the New York-based venture said.
AlTi is known for combining the breadth of a global firm with the service offering of a family office to deliver solutions designed to meet the full complexity of wealth and capital. As of April 2026, the business manages or advises on over USD 93 billion in combined assets and possesses a global network of more than 450 professionals.
Since AlTi’s inception, Nancy Curtin has served as Global Chief Investment Officer, delivering strong returns for clients and leading a global team of more than 50 investment professionals. She also held a similar role, along with the position of Head of Investments at Alvarium Investments, until it merged to create AlTi.
Nancy Curtin’s experience-rich portfolio also includes leadership positions at Close Brothers Asset Management and Fortune Asset Management, where she led the building of businesses in the wealth and institutional space.
“Her early career included senior executive and investment roles at Schroders and Barings Asset Management. Ms. Curtin currently serves as Chairperson of the Board of Directors of Digital Bridge Group Inc, a global digital infrastructure private equity, private credit, and alternatives firm,” AlTi noted.
“On behalf of the Board, I want to thank Mike for his many years of dedicated leadership. Mike’s vision and commitment have been instrumental in building the collaborative culture and relentless focus on delivering excellence for clients. This truly sets AlTi apart,” said Timothy Keaney, Chair of the Board.
“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. We are confident that under Nancy’s leadership, we will build on the strong foundation established under Mike’s tenure, as we continue to strengthen our platform and expand the opportunities we bring to clients,” he added.
“It has been my immense privilege to lead this Company since its inception. I am incredibly proud of what this team has built and grateful to the clients and partners who have been critical to our success,” Michael Tiedemann said in his farewell note.
Reacting to her appointment as the interim CEO, Nancy Curtin said, “I am honoured to step into the role of Interim CEO at this important juncture in AlTi’s growth trajectory. 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. Given the strength of our institutional-quality platform, we will also continue to expand our offering to foundations and endowments globally. Our core business remains highly differentiated for the clients we serve, and I look forward to partnering with our tremendous team globally to build on this momentum.”
