MJ&Cie

MJ&Cie

MJ&Cie opened in Paris in 2001 under François Mollat du Jourdin, a former private banker at Neuflize and Merrill Lynch, and co-founder Corinne Louis, who oversees the legal and philanthropic advisory practices. Unlike family offices born from an operating business sale, the firm's starting capital is human: the founders' experience managing complex European and international fortunes for private-banking clients. It describes itself as the first independent multi-family office established in France, serving a constrained client count by design — a posture that signals resource concentration over asset-gathering. The investment posture spans direct co-investments, SPVs, private equity, hedge funds, private credit, infrastructure, real estate, and secondaries — a full balance-sheet mandate for families that want a single orchestrator. Real asset allocations skew toward European mixed-use value-add real estate across France, Germany, the UK, Portugal, and Switzerland, alongside agricultural land, vineyards, and forestry in France. The practice also advises on art, collectibles, crypto-assets, and rare earths, making it an allocator to passion assets and digital stores of value alongside traditional institutional strategies. Named partners map directly to these verticals: Alberto Haddad specializes in real estate, Otmane Jai leads investments as CIO with an agritech lens, and Alexandre Nahas runs the Geneva subsidiary NSC Advisor. The firm complements its investment services with legal-and-tax structuring, family-governance design, and a private-secretariat function that handles administrative and accounting consolidation. François Mollat du Jourdin also co-founded the Association Française du Family Office and chairs the European Network of Family Offices, placing MJ&Cie at the center of peer-exchange networks that often surface off-market deal-sharing — an informal sourcing advantage for club-style real estate and private deals. The office maintains a small strategic advisory board that includes Wild Geese Foundation director Denise Kenyon Rouvinez. The structural differentiator is a conflict-of-interest proof rooted in architecture: MJ&Cie advises entirely without proprietary financial products, meaning investment selection carries no retrocession or distribution-fee incentive. This pure-advisory constitution, common in Anglo-Saxon multi-family offices, was unusual in continental Europe when the firm launched in 2001 and remains a distinguishing feature alongside its Geneva gateway for Swiss private-banking coordination and tax-treaty planning.
