Invitation-only communities
Invitation-only communities publish criteria that describe their members but do not by themselves admit anyone; a nomination, an invitation or a committee decision does. They include capped bodies such as Chief Executives Organization, centimillionaire communities such as R360, curated founder communities and the traditional roundtables of large-company chief executives. The pages record what is known about the route in, and the qualification tool marks these organizations as requiring an invitation even where every published criterion appears met.
