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. Dotted grey bars are our estimate for rounds that didn't state one: the round's share price × the shares outstanding in its filings. Same measure as blue, but rougher. Dashed amber bars are a SAFE or convertible note's valuation cap — the most it converts at, not what the company is worth, so don't compare them with the other bars.
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.
