What gets verified

Every Publication Vetting Report draws from these public sources. Where a source returns nothing useful for the subject, the relevant section degrades gracefully with an explicit insufficient-evidence tag rather than padding with guesses.

SourceWhat it tells us
CrunchbaseCompany record. Founding date, employees, funding rounds where applicable, current investors, parent company.
Masthead and about pagesEditorial leadership, executive editor, contributing editors, editorial-staff composition.
RSS feedsPost cadence, beat consistency, byline distribution, multi-author versus single-author footprint.
WikipediaFounding history, ownership-change record, controversies of record, awards.
Similarweb / Alexa trafficEstimated monthly unique visitors, top-traffic countries, traffic-trend signal. Tagged as estimates.
News mentions across other publicationsHow peer publications describe this publication. Awards mentions, controversy mentions, citations of work.
SEC EDGAR (publicly traded media)10-K and 10-Q disclosures of subsidiary publications, segment reporting, audience figures.
IRS 990 filings (nonprofit media)Disclosures of revenue, executive compensation, foundation grantors.
Public corrections archiveWhere the publication maintains a public corrections page, the corrections cadence and severity over time.
Substack publicationsPost cadence, paid-tier presence, subscriber-count signal when public, editorial-team composition.
What we never do: invent traffic numbers, characterize a publication as "biased" without sourced public commentary, fabricate a quote, or cite a source we did not actually read. Sections without evidence are tagged, not guessed.

How we identify the right publication

Same-name publications are a real failure mode. We solve this with three independent gates.

Gate 1 — Domain match

The publication's primary domain is the canonical identifier. Domain-match search resolves to Crunchbase, Wikipedia, and masthead URL.

Gate 2 — Disambiguation card

Multiple candidates surface as a disambiguation card with parent company, founding date, primary beat, and editor-in-chief.

Gate 3 — Confirm before charge

Wrong-publication reports are credited back automatically.

Defamation guardrails

We do not characterize publications as "biased" or "fake news" without sourced public commentary.
