SG M&R

SG M&R

SG M&R was founded in Geneva in 2010 by Charles Mardini, Ygal Rabinovici, and Société Générale Private Banking (Suisse) SA, which took an initial 25% stake. Mardini and Rabinovici had worked together for more than 25 years, starting their careers at Compagnie Bancaire Genève. The minority ownership by a French banking group gave the firm early institutional backing while preserving operating control for the two founders through their holding company, M&R SA. The firm structures its offering around two core lines: discretionary wealth management and a family office service that consolidates reporting across financial and non-financial assets. SG M&R expressly runs an open-architecture model, working with several dozen unaffiliated custodian banks and a network of external specialists. That design lets the firm select partners on merit rather than balance-sheet affiliation. The firm is authorized by FINMA as a wealth manager and supervised by the supervisory body AOOS. SG M&R describes its scale as placing it among the top tier of Swiss wealth managers, though it does not publish an AUM figure. EY serves as both auditor and prudential auditor. In July 2024, Société Générale sold its Swiss private banking subsidiary and London-based Kleinwort Hambros to Union Bancaire Privée. Following that transaction, Mardini and Rabinovici bought out Société Générale’s 25% stake in SG M&R, becoming the firm’s sole shareholders. CEO Raphaël Gaille and CIO Alessio Cimoli lead day-to-day operations from the firm’s single office on Place Longemalle in central Geneva. SG M&R’s most unusual structural feature was its 14-year minority partnership with a large French banking group — a hybrid ownership that few independent Swiss wealth managers have replicated. With that partnership now unwound, the firm operates as a fully partner-owned entity, yet retains commercial collaboration with Société Générale. That sequence creates a governance history unusual for a Geneva-based multi-family office: it started inside a strategic bank relationship, scaled rapidly under partial institutional ownership, and then returned to full founder control through a clean buyout.
