Mike Tiedemann

Spear’s Review 

Mike Tiedemann is the CEO of international wealth and alternatives management firm AlTi. 

Tiedemann was founding partner, CEO and chairman of the investment committee at Tiedemann Advisors, and CEO at Tiedemann Investment Group before the merger that brought together his business, Alvarium and the Cartesian Growth Corporation. 

AlTi, now one of the world’s largest publicly traded money managers that focuses on UHNW individuals, is essentially a multi-family office. As of March 2024, the firm had $71 billion in assets under management, invested $2 billion alongside clients and committed $5 billion to impact strategies.

Tiedemann has told the press that the firm is ‘continuing to simplify and streamline our business, but we want to remain dynamic and understand what long-term trends are and how we can best participate and serve our clients in the best way possible’.
