Investors are ranked by number of tracked investments, not by capital. We only know round sizes, not the cheque each investor personally wrote, so we do not publish a per-investor capital figure. "Capital deployed since 2021" is the total across all tracked rounds, each counted once. Original round currencies are shown on the Fundraises page. Last updated Jun 29, 2026.
