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

Partnership and content-licensing deals (e.g. with medical journals), and the Series B valuation, which we could not verify from a source we could read.

Updates & corrections

This page stays at one address and is updated in place; the “Last updated” date above drives the citation and the dataset metadata. Corrections: hello@growthnavigatefunding.net. Informational only; not investment advice.
