Your satisfaction with our Family Office Forum Collection is our primary concern. Quality, not quantity.

Each time, we strive to bring together 100+ of a highly diverse and select group of Family Offices and UHNWIs, along with a few thought leader industry experts and provide them a private platform where they can discuss the most pertinent Family Office topics on governance and investments and network with their peers.


The Family Office Forum Collection focusing on Knowledge, Connections, and your Privacy.

We devote ourselves exclusively to a small number of individually designed events that are each tailor-made to include local, and regional topics of relevance with an international flavour.

We understand the importance of your privacy, we don’t even provide any delegate lists at our six annual editions of Family Office Forums.

Whether attending, speaking, or partnering with us - your needs and expectations come first. By bringing you together with your peers, we create a unique access for you to a range of specialist contacts, knowledge and opportunities. Our no-pitch environment is appreciated by all our attendees and partners..

We strive to stay neutral

We are editorially independent; our forum agendas are influenced by the most crucial and timely topics that keep family principals and their family offices awake at night and offer inspiration to them.

We don’t take commissions.

  • “Very stimulating and encouraging!”–Viscount Chris Portman, Principal, Portman Estate

  • “On behalf of Dubai Economic Council, our sincere gratitude and heartfelt thanks - all responses have been enthusiastic about the content and the overall quality of the conference”...–Tarek Hijjiri, Dubai Economic Council
