Frequently asked questions
Who runs investment decisions at AlTi Tiedemann Global?
Michael Tiedemann serves as CEO. Alexander de Meyer chairs the executive committee. Investment authority rests with this leadership group and the board that includes outside shareholders.
How does AlTi Tiedemann Global source proprietary deal flow?
Deal flow arrives through the networks of its founding entities, its three outside strategic shareholders, and participation in family-office forums such as YPO and Campden Wealth.
Is AlTi Tiedemann Global structured as a single family office or does it operate more like a venture firm?
It operates as a multi-family office that also runs alternative-investment platforms. The 2023 merger combined a legacy family office with an alternatives manager and added external capital partners.
Does AlTi Tiedemann Global participate in fund commitments or only direct deals?
It uses both channels. The firm commits to hedge funds and fund-of-fund vehicles while also holding direct real-estate assets in the United Kingdom, Germany and France.
Where does the underlying wealth come from?
The Tiedemann side originates from Carl Tiedemann’s hedge-fund activities. The Alvarium side brings additional institutional and family capital that entered through the 2023 combination.
Does AlTi Tiedemann Global maintain philanthropic structures, and how are they separated?
Yes. Global Partnerships and Tiedemann Philanthropy sit alongside the investment platform. The record does not detail legal separation mechanics.
What is AlTi Tiedemann Global’s known posture on co-investments alongside external GPs?
The firm has accepted strategic co-investment from Allianz X, Peterson Group and Dilmun Family Office. These relationships sit on the shareholder register rather than in individual deal syndicates.
