Alvarium Investments, previously known as LJ Partnership, has acquired French asset management firm Iskander.
Financial terms of the transaction were not revealed.
Iskander focuses on large private investors.
The acquisition is the fifth deal by Alvarium in the past eight months.
With the latest deal, Alvarium’s presence reaches into the Italian, French and Australasian regions.
LJ’s rebranding to Alvarium was completed recently.
Guggenheim Investment Advisors (Hong Kong), snapped up by LJ in 2016, will also operate under the new brand.
Alvarium CEO Alexander de Meyer said: “In recent years we have seen sustained and measured growth, bringing on and integrating new teams and service offerings for the benefit of our clients and partners.
“Today we announce our latest acquisition in France as well as a rebrand that consolidates our international operations under one brand.
“Both mark an exciting new chapter for the firm, reinforcing our position as one of the leading independent global investment boutiques.”
Currently, Alvarium has eleven offices and a staff headcount of 200.
The business oversees more than $15bn in assets.
Last July, the firm secured an investment from family office Dilmun in lieu of a 40% stake sale.
Additionally, the firm named Ken Costa as its new partner and co-chairman along with Ali Bouzarif as partner.
