Single Family Office vs Multi-Family Office (SFO vs MFO)

How dedicated SFOs and shared MFOs differ on cost, control, services, and the right asset threshold.

Single Family Office (SFO)

A private, dedicated organization that serves one ultra-wealthy family, with full control over staff, strategy, and privacy. Typically requires $250M+ in investable assets.

Multi-Family Office (MFO)

A firm that serves multiple families and shares infrastructure, talent, and best practices. Lower cost of entry — often viable from $25–50M per family.
