Côme

What Côme does

Côme Maison Financière is a privately-held, fee-only multi-family office founded in Paris in 2016 by Julien Magitteri, a former HSBC Private Banking and Bordier et Cie director. The firm delivers open-architecture wealth management services across investment advisory (listed markets, private equity, private debt, real estate, infrastructure), wealth engineering, family governance, succession planning, philanthropy, and concierge services to ultra-high-net-worth individuals, entrepreneurs, families, and elite athletes. It operates a multi-pole structure spanning Côme Maison Financière (core MFO), Côme Asset Management (dedicated asset management), Côme Athlètes Office (athlete wealth management with the Douillets), Côme Real Estate (off-market real estate investment banking with Passy Invest), AntCo by Côme (cross-border non-resident advisory), Barnes Family Office by Côme (luxury real estate), and Côme Ensemble (endowment fund), with three proprietary conviction funds (Demeures, Borobudur, Arcade).

The firm's business model is fee-based (honoraires) rather than commission-driven, deliberately aligning its interests with client outcomes and ensuring independence from product manufacturers. Côme has grown organically to approximately 30+ professionals across eight offices in Paris, Bordeaux, Lorient, Nice, Rouen, Geneva, Luxembourg, and New York, with a dedicated B2B development function serving CGPs and mono family offices that use Côme as a mutualised platform. The firm is registered with ORIAS (#16004946) as a Conseiller en Investissement Financier (CIF), is a CNCGP member regulated by the AMF, and has won multiple industry awards between 2024 and 2026 (Occur, Hubfinance, Décideurs Magazine, Sommet du Patrimoine). Technology is not proprietary; the firm uses standard financial data tools, consolidated reporting systems, and AI-assisted analysis within its Risk Control function, supported by a Junior Data Manager with AI/data science training.
