Classification
Office type, AUM band and sector focus assigned where the evidence supports it.

List of the 3,500+ Largest Multi Family Offices in the World [2026] · Single seat
Ranked by disclosed AUM band, then by named-contact depth: the same ranking the per-country pages use. Offices without a disclosed AUM band rank below those with one. The file is sorted by that ranking and contains all 3,725 qualifying multi family offices worldwide in our dataset, not a sample. The 3,500+ in the title is the minimum we guarantee across refreshes.
An Excel workbook (Overview, Offices and Contacts sheets) plus a flat CSV, delivered as an instant download after checkout and ready to import into your CRM.
Every record reflects the latest quarterly review; the exact data vintage is shown at the top of this page. For 12 months after purchase, each new release is included at no extra cost. List membership can shift between releases as office data changes.
Family offices rarely advertise themselves. Assembling 3,725 verified multi family offices worldwide with 16,813 named decision-maker contacts from public sources takes a research team weeks. This file is that research already done, sold as a one-time purchase rather than an annual platform contract.
Yes. 2,326 of the 3,725 offices (62%) include at least one usable email address: a firm or department inbox, a named decision-maker's direct email in the Contacts sheet, or both. Filter to those rows and you have a targeted email list. The difference from a plain email list is the research around it: every row carries the profile columns to qualify a firm before you write to it.
One purchase covers internal business use within your organization: import it into your CRM and use it for outreach, research and analysis. Reselling, republishing or passing the data outside your organization is not allowed; the full license terms are on our Terms of Service page.
Yes. Checkout issues a tax invoice together with your receipt, and you can add your company name and VAT or tax ID during checkout so the invoice is made out to your business.
Data downloads are final sale once delivered, which is standard for digital B2B data. To judge quality before buying, review the sample rows and the field-by-field completeness table on this page, or request the free sample from the site. Broken or incomplete downloads are fixed promptly, and if a delivery differs from what the page advertises we review it individually.
Search, filter and track every office — the same data this file is exported from, updated continuously. Need ongoing access instead of a one-time download?
