Profile

Founded 1991 (Sources disagree. Wikipedia gives 1991 (formally incorporated 1997) and Campden Wealth says IPI has "roots dating to 1991"; the IPI homepage says 1995 and the IPI membership overview says 1992. Recorded as 1991 as the earliest and most corroborated date.) 1999 (Founded by Michael W. Sonnenfeldt with a single group of six entrepreneurs in New York City who had recently sold their businesses. The name is widely reported to stand for The Investment Group for Enhanced Returns in the 21st Century, which TIGER 21 does not state on the pages reviewed. Headquarters city reported by secondary sources; TIGER 21 does not state it on its about page.)

Typical member IPI states a minimum of USD 30 million in assets to qualify and reports that members' average liquid holdings exceed USD 300 million. More than 48 per cent of members have belonged for ten years or longer. Members are wealth creators rather than salaried executives: current and former entrepreneurs, investment managers and senior executives, typically after a liquidity event, whose central problem has shifted from building a business to preserving and allocating capital.

Application process Candidates who meet the USD 30 million asset minimum apply through IPI's membership application portal and choose an individual or family membership. All applications are subject to approval. Members of IPI are automatically treated as qualified for Campden Club events and do not complete Campden's separate qualification form. Candidates submit an inquiry and are assessed by a Membership Development Director against the 5Cs. Vetting includes extensive background checks and interviews, and TIGER 21 states the process typically takes about two months. Meeting the capital minimum is explicitly not sufficient on its own.
Selectivity Not publicly disclosed. IPI states only that all applications are subject to approval. TIGER 21 states that meeting the US$20 million minimum "does not guarantee admittance" and that other qualitative requirements apply at its discretion. No acceptance rate is published.
