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 2023 seed round led by Benchmark (not re-sourced here), and secondary sales.
