Family Office
A private firm that manages one wealthy family's entire financial and personal life.
Purpose
A family office is a dedicated organisation built to preserve and grow the wealth of a single family (a single-family office) or a few families (a multi-family office). It consolidates investment management, tax and estate planning, philanthropy, and often concierge services under one roof, aligned entirely with the family's interests. Its deeper purpose is continuity: keeping capital, values and cohesion intact across generations.

Mandate & Incentives
Mandate
A family office has no external charter beyond serving the family that owns it; its 'mandate' is whatever mission and investment policy the family sets. In many jurisdictions it is structured to avoid registering as a public investment adviser precisely because it serves only insiders. Its guiding aim is usually multi-generational preservation of purchasing power alongside the family's non-financial goals.
Incentives
Freed from selling products or gathering third-party assets, a family office can take a genuinely long horizon and invest in illiquid, patient strategies few others can. But total alignment with one client also brings key-person risk, thin external scrutiny, and the danger of drifting toward the founder's biases. Staff loyalty and confidentiality are prized above visible performance benchmarks.
