Methodology
Every figure is computed at build time from PipelineRoad's curated institutional investor directory and fund-manager dataset. Reported assets reflect each entity's most recent disclosure; figures are deduplicated and scoped to asset owners (for LP reports) or active managers (for fund reports). Family-office and net-worth figures are widely reported estimates, not audited AUM. The page recomputes on every publish, so the numbers track the data as it is corrected and expanded.
