FY2020–FY2025 · from SEC filings · hover any figure for its sourceFigures as reported by the issuer in the filing shown on hover. Each year’s pill shows the assurance level of its filed statements — audited, reviewed (CPA review, less than an audit), or unaudited, as the filing’s own report or certification states it. A dashed pill marked * is inferred instead: the SEC minimum for an offering that size, which the issuer may have exceeded. No pill means we couldn’t tell. Headcount is the filing’s point-in-time count, not a year-end average. Manually corrected figures are marked “Corrected”.
Valuation over rounds
Pre-money — the valuation set before each round’s money came inBlue bars are the pre-money valuation the company stated for a priced round.
Share price over rounds
Disclosed sales come from the issuer's own filings (prior-offering lines, audited-statement notes) and are amount ÷ securities sold. A down round is a firm point more than 25 % below the previous firm point of the same share class on a comparable basis; the comparison ignores unverified and year-only lines.

From the company's SEC filings: share counts per class, each class's voting and conversion terms, and the holders of 20% or more that Form C requires (officers and 10%+ holders on Form 1-A). Filings name only large holders, so most owners — including crowd investors — are not listed, and a holder's percentage may be of its own class rather than of the whole company. Prices and crowd share counts are in today's share terms — adjusted for splits and conversions since they were sold. Hover a figure for its filing.

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.
