The HBS European Alumni Summit 2026 runs 25-27 September 2026 in Amsterdam, hosted by the Harvard Business School Club of the Netherlands, under the theme 'Leadership for One World'. A sister HBS alumni club's own event listing (HBS Club de France) publishes the dates, the city, the theme and the host club, and records the venue as still to be determined; the host club's summit domain (hbsnl.com) answers with a redirect to an iModules alumni sign-in, i.e. the summit surface is members-only and no public venue or speaker list is exposed. The programme is described by the clubs as keynotes, cross-sector panels and interactive sessions addressing how leaders navigate geopolitical, technological and social disruption, with a cultural programme alongside. The summit is the European series' next stop after Berlin (2017), Paris (2022) and Milan (2024). Access is alumni-facing and ticketed; no delegate roster, no speaker list and no ticket price are published. Nothing on this page is an attendance list, and no figure here is a deal, a commitment, an AUM or a net-worth claim.
