About this data. Figures are compiled from public sources — SEC EDGAR filings (Form C, C-AR, 1-A, 1-K) and funding-platform pages — and may be delayed, incomplete, or restated by the issuer. Financial statements are as reported by the issuer; each year is labeled with its assurance level (audited / reviewed / unaudited). A valuation cap is the conversion ceiling of a SAFE or convertible note, not an agreed company valuation; post-money figures are computed as pre-money plus amount raised and are not a traded price. Crowdonomics is not a broker-dealer, funding portal, or investment adviser; nothing here is investment advice or an offer to sell securities. Verify all figures against the linked EDGAR filings.
