Browse/filter by manager, type, size, and vintage; each fund links to its manager (GP). Fund size (`amount`) converts to the requested `?currency=` (default USD); `amount_source` carries the original native-currency amount. - name: People description: >- Person profiles (founders, executives, angels, and others). Subset of entities where `entity_type = 'person'`. Same response shape as founders, with company associations, education, and backgrounds. - name: Founders description: >- Founder profiles with company associations and education history.
