How the Rising score works

Budget first. A company needs evidence of money to rank high: a raise reported to the SEC or an announced growth ranking. Bigger raises count for more.
Fresh beats old. Every fact counts for less as it ages, over the window it usually takes a company to act on it.
Evidence stacks. A raise together with active hiring ranks far above either alone. Hot needs more than one kind of evidence.
Public facts only. Every fact on this page links to its source. No individuals are named.
