A family office is a private company set up to manage the investments, estate planning, tax optimization, and philanthropy of a single ultra-wealthy family (single-family office) or multiple wealthy families (multi-family office). They typically require a minimum of $100M–$500M in assets to be economically viable.
Family offices are a hallmark of billionaire wealth management. Unlike traditional wealth managers, family offices offer a comprehensive suite of bespoke services: direct investment into private equity, venture capital, real estate, hedge funds, tax and legal structuring, concierge services, and even next-generation education.
Many billionaires establish family offices to preserve and grow multigenerational wealth outside the constraints of public markets.
