Every senior leader eventually faces the same paradox: the higher you climb, the fewer people you can talk to openly. Peer networks exist to solve that problem. Some are seventy years old and count tens of thousands of members; others select a few hundred people a year. This guide maps the main ones, from the largest global communities of chief executives to the selective fellowships, and explains how to tell them apart.
YPO: the largest community of chief executives
Founded in 1950 in the United States, YPO (Young Presidents' Organization) is the reference network for company leaders. According to its own figures it brings together more than 35,000 members in over 150 countries, organised in local chapters and in confidential forums of eight to ten members who meet regularly under strict rules of confidentiality. Membership is reserved for chief executives, presidents and founders whose companies exceed revenue and headcount thresholds, and new members join before the age of 45; older members continue in YPO Gold. Its strengths are scale, the density of chapters in most major cities and a well-tested forum method. Its limits follow from the same choices: it is a community of business owners and executives, not a place where a minister, an NGO director and a CEO sit at the same table.
EO: founders talking to founders
Entrepreneurs' Organization was created in 1987 and gathers, by its own account, more than 18,000 entrepreneurs in some 80 countries. The entry ticket is a founder, co-founder or owner position in a company above roughly one million dollars of annual revenue. The heart of EO is also the forum, plus learning programmes and an accelerator for younger companies. EO is younger in spirit than YPO and closer to the day-to-day of growing businesses.
Vistage: peer advisory boards with a professional chair
Vistage, born in 1957 in Milwaukee under the name TEC, follows a different model: small groups of chief executives who do not compete with each other, led by a paid, trained chair who also coaches each member individually. The organisation reports around 45,000 members across more than twenty countries. It is closer to executive coaching delivered in a group than to an association run by its members.
The selective fellowships
A second family of networks selects rather than recruits. The Forum of Young Global Leaders, created by the World Economic Forum in 2004, picks each year a class of leaders under 40 from business, government and civil society for a multi-year programme. The Aspen Global Leadership Network gathers the fellows of the Aspen Institute's leadership programmes around the idea of values-based leadership. Chief, launched in the United States in 2019, is a network reserved for women executives that has grown to tens of thousands of members and opened in London in 2023. C200, founded in 1982, brings together women who lead significant businesses. These circles offer prestige and access; they are not, by design, open to application from everyone.
Advocacy bodies are not peer networks
Business Roundtable in the United States, the World Business Council for Sustainable Development or the B Team gather chief executives around public positions and policy work. They matter, but their purpose is collective influence, not the confidential exchange between peers that defines a forum. Confusing the two leads to disappointment on both sides.
How to choose
Five questions settle most decisions. Who sits in the room: only business executives, or also public decision-makers and civil-society figures? What is the format: a large community with many events, or a small forum that meets monthly? How are members selected: on age and company size, or on impact and commitment? What is the total cost, in fees and, above all, in time? And what is the organisation's purpose beyond networking: learning, advocacy, or impact?
Where the World Leaders Society stands
The World Leaders Society, founded in Paris in 2025 as an independent non-profit association, made a deliberately different choice. Its forums of eight to twelve members bring together business leaders, elected officials and senior public officers, social entrepreneurs and civil-society figures, without an age limit, selected by an independent approval committee. It adds a public editorial dimension, the WLS 100, an annual selection of the hundred leaders shaping the century, and a commitment to transparency: published accounts, an annual impact report, independent strategic and ethics councils. It does not aim to replace a global network of chief executives; many of its members belong to one. It offers what those networks structurally cannot: the conversation across sectors.
The most useful room is not the largest one. It is the one where the person across the table sees the same problem from a different side.WLS Editorial
