Methodology
Figures are aggregated from Indexed's live database of 98,770 company profiles and 22,284 investors. Company totals include publicly listed and inactive businesses. Company funding totals and individual event tables have different coverage; each report states its population and period. Amounts are shown in USD where available, and undisclosed amounts are excluded from dollar totals. Source coverage varies by record; follow company and event links to inspect supporting evidence. Report generated October 2026. Free to cite with attribution to Indexed.
Totals include recorded grants and other qualifying funding, not just equity. Debt financing, IPO proceeds and exit consideration are excluded from these funding totals. Valuations are company values, not capital raised. How funding is counted.
