Figures 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; no pill means the filing didn’t state one. Headcount is the filing’s point-in-time count, not a year-end average. Manually corrected figures are marked “Corrected”.

Gravity Power Series B-2 Preferred Stock 2

A dashed amber step is a SAFE/note valuation cap — a conversion ceiling agreed for that instrument, not a priced valuation of the company. Steps are not comparable across bases.

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.
