Brain Trust

A brain trust is a group assembled for intellectual firepower on hard problems — often cross-functional, senior, and valued for judgment rather than authority. FDR's original Brain Trust was a policy advisory circle; in modern careers, the phrase describes experts you convene (together or separately) when facing ambiguous strategy.

Brain trusts differ from generic networking in depth and reuse: the same minds weigh in across multiple decisions, so they accumulate context on your goals and patterns. That continuity improves advice quality but requires you to manage confidentiality and competing opinions.

For solo professionals, a brain trust might be three veterans in your field plus one operator from an adjacent industry. For founders, it might include customers, investors, and technical leaders. The key is selecting for cognitive diversity and willingness to disagree, not for status alone.
