TIGER 21 vs R360

Two peer communities for wealth holders separated by a factor of five in their published bar — and by whether they publish a price at all.

Read down each column for one organization, across a row for the difference. A bronze mark at the left of a cell means the organizations differ on that row. A dash or “not published” means the organization does not disclose the fact — it is not a zero.

TIGER 21

Ultra-high-net-worth entrepreneurs, investors and executives with at least US$20 million in investable assets, many of them post-exit.

TIGER 21 and R360 are the two most-cited peer organizations for people whose subject is their own capital rather than their company. TIGER 21 publishes a floor of US$20 million in investable assets, a US$5,000 initiation fee and annual dues of US$34,000 in North America (US$51,500 for its Family Office groups), and describes an eleven-meetings-a-year cadence with a moderating Chair and an annual Portfolio Defense in which a member's whole balance sheet is examined by the group. R360 describes its members as families with a net worth above US$100 million, admits by invitation and fit through a Membership Committee, organises chapters around six forms of capital — financial, intellectual, social, human, emotional and spiritual — and publishes no dues; the figures in circulation come from press coverage.

The two are therefore comparable only at the top of TIGER 21's range. Below US$100 million the question does not arise. Above it, the choice is between a structured monthly investment-and-life peer group with a published price and a smaller invitation-only community whose calendar is built around family, legacy and purpose as much as investment.

Primary audience Centimillionaire families: individuals and families with a net worth above US$100 million. Ultra-high-net-worth entrepreneurs, investors and executives with at least US$20 million in investable assets, many of them post-exit.
Typical member Members are wealth creators and their families rather than salaried executives. R360 states members have a net worth above US$100 million; its December 2025 release describes more than 170 members collectively stewarding over US$100 billion, implying an average well above the entry threshold. 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.
Qualification
Minimum net worth Net worth above US$100 millionR360's FAQ states "members of R360 have a net worth above $100 million". R360 also states that membership is by invitation and fit, not simply financial qualification.verified September 2026 · source ↗ No published minimum net worth
Minimum investable assets No published minimum investable assets At least US$20,000,000 in verifiable investable assets or qualifying net worthExcludes personal-use assets. TIGER 21 states that meeting the minimum "does not guarantee admittance".verified September 2026 · source ↗
Invitation required Yes No
Sponsor required Not documented Not documented
Application process Prospective members submit a membership inquiry through R360's website, after which the Membership Committee evaluates them. R360 states that qualification is by invitation and fit rather than by net worth alone, and has introduced an assessment for candidates. 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 R360's founder stated in a December 2025 press release that "seventy-two individuals, including nine billionaires, have been turned down by our membership committee". No acceptance rate is published. 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.
Cost
Annual dues Not publicly disclosed. R360 publishes no dues on its own site.

Every value comes from the same records as the individual pages; a dash means the fact is not published or verifiable. Rows are grouped by what a reader decides on, not by data type.

Which is more appropriate for whom

Editorial analysis, separated from the record above. It follows the methodology. Neither organization is declared better; the question is fit.

TIGER 21 tends to suit people between US$20 million and the low hundreds of millions who want a disciplined monthly group, a moderator, an explicit non-solicitation rule and a known price, and who value the Portfolio Defense as a forcing device. It is easy to price and easy to rule yourself out of, which is unusual in this category.

R360 tends to suit families above US$100 million for whom the investment conversation is one of several — succession, family dynamics, philanthropy, the next generation — and who are content to be assessed on fit by a committee rather than to apply against a published test. Anyone comparing the two on price should note that only one of them has published one; the widely quoted three-year figure for R360 is press reporting, not the organization's own statement.
