Family office

A family office is a private organization that manages the wealth of a single family — or, as a multi-family office, several — and may include direct business acquisitions among its investments. Unlike a private equity fund, a family office usually has no fixed fund life, which can mean a longer, more flexible holding horizon.

Reviewed

Family offices vary enormously in size and approach, from a small team managing one family’s assets to organizations that behave much like institutional investors. What they generally share is patient capital — money that does not need to be returned to outside fund investors on a set schedule.

How a family office differs from a private equity fund

  • No fixed fund life, so there is no built-in pressure to sell within a set number of years
  • Investment decisions often involve the family directly, not only a professional deal team
  • Mandates can be broader and less formulaic than a fund’s stated investment thesis
  • Some acquire a business to hold indefinitely, closer to how a strategic buyer might operate

What this can mean in a sale

A seller weighing offers from a family office and a private equity fund is often weighing patience against process. A family office may offer more flexibility on timeline and structure; a fund typically brings more standardized process and, often, a faster, more predictable path to closing.
