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 $25M expansion of the Series C announced in May 2023 (not re-sourced here), earlier seed to Series B rounds, and government contracts.
