Methodology & status definitions

How each row is labelled and calculated.

Closed round

A primary round announced by the company or confirmed in the press, bringing new money to the company.

Valuation ÷ run-rate

Post-money valuation ÷ the run-rate the company stated in that announcement (GNF calc.). Where the run-rate is “crossed” or “over” a figure, the multiple is shown as “under X×”. No row qualifies here unless shown, so no multiple is invented.

What is not a separate row

The 2016–2018 seed, Series A and $18M Series B, a March 2025 reported tender at up to $25B that Scale did not confirm, secondary-market prices, and the shareholder distribution of Meta’s proceeds (described in the Meta row).
