International leadership organizations

International leadership organizations select for influence rather than for company size or wealth: chief executives of the largest companies, nominated young leaders, fellows chosen for civic leadership, members of foreign-policy and economic bodies. Almost all are invitation- or nomination-only, and their published criteria describe members more than they admit them. The requirement rows record what is published (a title test, an age cap, a fixed term) and the pages say where admission depends entirely on a nominating committee.
