| Typical member | Members are families that own or oversee an operating enterprise or a dedicated family office, together with the executives who run those offices. FOX does not publish an asset floor, and its own materials describe the community in terms of role rather than wealth band. | 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 | Prospective members enquire through the FOX website, after which FOX opens a membership conversation and assesses the applicant against its own criteria. Non-members may first attend open workshops, public webcasts and virtual showcases. Council membership is a separate decision that requires a commitment to active participation and an additional fee. | 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 | 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. |
