At Paris Wealth Day 2025, Hubfinance spoke with Julien Magitteri, President and Founder of Côme Maison Financière, about a clear ambition: to make the Family Office accessible and put finance back at the service of purpose.
Founded in 2016, the firm champions a model based on multidisciplinarity, independence, and accountability—an approach that challenges the conventions of traditional wealth management.
Democratizing Access to the Family Office
Côme Maison Financière has made it its mission to make the expertise of a full-service Family Office accessible to a wider audience.
Its team supports investors across three complementary areas:
- Private Equity, to finance the productive economy;
- the public market, a foundation of liquidity;
- and real estate through Club Deals, developed with Barnes Family Office.
This structure enables the development of coherent, sustainable, and accessible investment strategies, while promoting collaboration among different investor profiles.
Reconciling Performance and Impact
For Julien Magitteri, wealth performance has value only if it is sustainable over the long term and contributes to major economic and societal transformations.
Côme supports executives and entrepreneurs at key moments in their wealth management journey—sale, transfer, or reinvestment—with an approach grounded in technical expertise, independence, and a deep understanding of the client.
A “Multi-Mono-Family Office” model
Neither a traditional Multi-Family Office nor an isolated structure, Côme Maison Financière champions a hybrid model: the “Multi-Mono-Family Office.”
Clients come to us seeking specialized expertise, flexibility, and a collective vision.
At Côme, a client with one million euros can co-invest alongside another with one hundred million: the goal is to bridge the gap between wealth and generations.
Discover the full interview and the philosophy of a firm that puts capital to work for the collective good.
