The Paris Private Equity team advised Parquest and Allen's management on an agreement for Qualium Investissement to acquire a majority stake in the group, a leading player in private wealth management and multi-family office services.

This transaction marks a significant milestone in Allen’s growth journey, with the ambition to strengthen its position in the domestic market and accelerate its international expansion.

Founded in 2006, Allen initially focused on private wealth management under the Carat Capital brand, before expanding into multi-family office services through Hedon Family Office, in response to the evolving needs of its clients.

The Goodwin team was led by Thomas Maitrejean and included Rodolphe Amaudric du Chaffaut and Marjorie Ladsous on corporate aspects.
