London remains, with New York, the city where the greatest number of leadership networks have a physical home. The British tradition adds something the continent knows less well: the members' club, where belonging matters as much as method. For a leader based in France, the United Kingdom is the nearest ecosystem where international networks are dense, and where the rules of confidentiality were, quite literally, invented.
The Institute of Directors: the institution
Founded in 1903 and granted a Royal Charter in 1906, the Institute of Directors is the professional body of company directors in the United Kingdom. From its headquarters at 116 Pall Mall it offers, to some twenty thousand members according to its figures, training and certification in governance, a policy voice and a network of regional branches. It is less a peer forum than an institution that professionalises the role of director, with the club life that goes with it.
Vistage UK and The Alternative Board: facilitated peer boards
The American model of the peer advisory board is well established in Britain. Vistage UK runs groups of chief executives led by experienced chairs, and The Alternative Board (TAB) offers monthly boards for owners of smaller businesses with a facilitator. Other providers of peer groups for chief executives exist across the country. The common promise: a confidential board of non-competing peers, a facilitator, and individual coaching between sessions.
The Supper Club: founders of scale-ups
Created in 2003 in London, The Supper Club is a community of founders and chief executives of growing companies, typically above one million pounds of revenue. Its format mixes dinners, peer roundtables and expert sessions, with a strong culture of candour between entrepreneurs who have faced the same growth problems.
Founders Forum: by invitation
Founded in 2006 by Brent Hoberman and Jonnie Goodwin, Founders Forum is an invitation-only community of technology founders, investors and chief executives, with flagship gatherings in London and editions abroad. It is the British equivalent of the selective circles: prestige, access and a curated room rather than an open application.
YPO, EO and Chief in London
The large international networks are all present. YPO has several chapters in London and the United Kingdom, EO has an active London chapter, and Chief, the American network for women executives, opened in London in 2023. Their criteria are those of the parent organisations, described in our world guide.
Chatham House and the rule that bears its name
Chatham House, the Royal Institute of International Affairs founded in 1920, is a policy institute rather than a peer network, but it deserves a place here for two reasons: its membership programme gives access to a rare quality of debate on world affairs, and it gave its name to the rule of confidentiality now used by most forums, including those of the World Leaders Society. The RSA, with its fellowship, plays a comparable role for social innovation.
The members' clubs
The Reform Club, the Athenaeum and their peers on Pall Mall and St James's are the historical form of the leaders' network: a house, a membership committee, and conversations that never leave the building. More recent houses have adapted the formula for the creative and technology industries. They offer belonging and place; the working method is left to the members.
What this means for a leader in France
For a French leader, London offers the densest concentration of international peers within two hours of Paris. The World Leaders Society, founded in Paris in 2025, was designed with this proximity in mind: an independent, cross-sector circle of business leaders, public decision-makers and civil-society figures, with no age limit, whose forums apply the Chatham House rule and whose gatherings bridge Paris, Europe and Africa. It complements rather than replaces a London membership, and it brings to the table the voices that most executive networks leave outside: elected officials, senior public officers and the leaders of civil society.
Confidentiality was invented in London; the conversation across sectors still has to be built.WLS Editorial
