Family offices as compact cards: class (single, multi, embedded...) with confidence, whether they invest directly, sectors and asset classes on record, check size where stated, direct investment count, latest investing activity (private or public 13F/13D), and counts of people, sponsor and real estate relationships. A list filter sorted by one column: for a ranked answer to a buyer's criteria use rank_family_offices. Filter by states or region, canonical industries, direct investing, manager allocation, recent activity, AUM, an event type since a date, or a named co-investor. Returns dfx:fo: ids. ACCESS: without a paid DFX plan on the vertical, a list returns its first 5 rows in full and a count of the rest by type (locked.count, locked.by_type), never the rows; a record names its subject and the first 3 related names per section; contact values (email, phone, profile URLs) and decision-maker names are never returned, only their types and counts. Every answer says what it withheld in `entitlement` and `locked`. Full access: DFX Intelligence, 7 days free at https://dfxintel.com/data-factory/plans.
