Figures are aggregated from Indexed's live database of 100,049+ private companies and 22,293+ investors. Every funding round is sourced from a verifiable public record; duplicates are merged and only rounds meeting a confidence threshold are counted. Amounts are whole USD; undisclosed rounds are excluded from dollar totals but counted where noted. "Documented" means announced with a citable source — true market totals are higher.
