42 of the largest family offices, with the figure behind each ranking

How to use this list

1. 1

   Warm path first. Look each name up on LinkedIn and check who you know in common. An intro from someone they trust beats the best cold email you will ever write.

2. 2

   One line on why them. Family offices invest their own money and nobody makes them answer. Name something they backed, wrote or said that connects to what you build.

3. 3

   Ask for 20 minutes, not money. The first email asks for a call. Keep it short, link the deck, and make it easy to say yes to a date.

4. 4

   Follow up once. A week later, one short note with something new: a customer, a number, a hire. Then let it go and move to the next name.

How we built it: Researched on 7 October 2026. Each office is labelled with the figure we could source and what it measures: office assets under management, the family's net worth (Forbes or Bloomberg), or the net asset value of a listed family holding company. These are not like-for-like, so read the label, not just the order. Several heads come from Wikipedia and may be out of date.
