Family Office Forum New York 2026 is the New York edition of Prestel & Partner's family office forum series, held on 13–14 October 2026 at The Harvard Club, 35 West 44th Street, Manhattan — the 1894 clubhouse the organizer itself names as the venue. The organizer's own pages describe the format as a strictly private two-day forum under the line “FUTURE PROOF YOUR FAMILY OFFICE”: interactive panels, all-day networking and “no sales pitches”, with the attendance test spelled out on its site — wealth owners and single family offices attend free of charge, while providers of products, services or coinvestment opportunities pay a delegate pass or sponsorship, and every application is reviewed individually so that buy-side family offices outnumber sellers in the room. Its own 2026 archive blocks record the size of the room (“2026 Agenda — When 127 Family Offices met”) and its current page states that after “a great event in 2026 with 100+ Family Offices from all over the US and beyond” the series is preparing its announced 8th New York edition for 19–20 October 2027 at the same venue. SOURCE-DATING NOTE: the organizer page fetched for this node is already the 2027 edition page, so every 2026 fact recorded here is taken from that page's 2026 archive blocks (2026 agenda, 2026 report, 2026 speakers) and from the venue-day attendee post cited in sources[] — not from the 2027 programme. One attendee published a venue-day frame of the forum's own banner stand in the club's wood-panelled rooms on 18 October 2026, writing “two days at the Prestel & Partner Family Office Forum in NYC — 100+ family offices”; that frame is cited as evidence only and is deliberately NOT rehosted, because an attendee publisher does not clear the photo bar. Public OSINT only: the organizer publishes no delegate list and no per-session roster for this edition, so no attendee beyond the organizer's own 2026 speaker line is named, and no capital figure, AUM, deal or net-worth is asserted here.
