Eric Sturdza wants to build up a fourth pillar: the Swiss bank is buying a family office and merging it with its wealth management activities

Eric Sturdza is buying Lagane, a Geneva-based family office, in a bid to build up a fourth pillar of its business, the banking groups said in a statement on Tuesday.

Lagane will be integrated into independent asset manager Coges Corrateri Gestion, which Sturdza bought five years ago. The bank aims to expand its offering for the wealthy to include sophisticated family office-style services. The business would represent Sturdza's fourth arm, after private banking, asset management, and investment management. 

Sturdza said it can more adequately meet the demands and expectations of its wealthy clientele with family office services, which will be offered under the brand Coges Corraterie Gestion Wealth Management and Family Office. The unit will be run independently by Michaela Zanello Sturdza, Stéphane Gibert and Jean-Pierre Lagane.
