TLDR:
A family office is a private wealth management organization that serves ultra-high-net-worth (UHNW) families—typically those with $100M+ in investable assets. Family offices provide comprehensive financial and lifestyle services that go beyond what a traditional wealth manager offers, including investment management, tax planning, philanthropic guidance, estate planning, family governance, and concierge services.
Single-Family vs. Multi-Family Offices
Two main models exist: single-family offices (SFOs) serve one family, with all resources dedicated to that family—typical minimum assets $250M-$500M+ to justify the costs; multi-family offices (MFOs) serve multiple families, sharing infrastructure and expertise—typical minimum assets $25M-$50M per family. SFOs offer maximum customization and privacy; MFOs offer cost-effectiveness and access to professional infrastructure smaller families couldn’t afford alone. Globally, an estimated 10,000+ SFOs and 1,000+ MFOs manage trillions in assets.
Investment Activities
Family offices have become significant investment forces. Typical activities: direct investments in private companies (often as co-investors with PE/VC or directly), fund investments (allocating to VC, PE, hedge funds, real estate funds), real estate (often through direct holdings and fund investments), public markets (equity, fixed income, increasingly alternative assets), and increasingly impact investing and philanthropic activities. Major family offices have professional investment teams comparable to institutional investors—former Goldman/Morgan executives, ex-PE partners. The “Family Office Investment Survey” by major banks shows family offices now allocate 40%+ to alternatives.
Turkish Family Office Landscape
Türkiye has a substantial UHNW population concentrated in major business families—Koç, Sabancı, Eczacıbaşı, Doğuş, Anadolu, Yıldız, Boyner, Mehmet Cengiz, and others. Most large Turkish family wealth is held through holding company structures (Koç Holding, Sabancı Holding, etc.) which combine operating company management with investment activities. Dedicated family offices in the modern sense are less developed in Türkiye than in the US/Europe but growing—particularly for first-generation tech wealth (founders of Turkish tech successes like Trendyol, Getir, Hepsiburada exiting and forming wealth management structures). Cross-border family office structures (often through Switzerland, Luxembourg, or Dubai) are common for Turkish families with international wealth.
