A useful question names the company or market, the time period, and the decision it supports. “Which provider is listed for this service?” is more testable than “Who is winning?” Choose sources that can answer the narrower question.
Preserve provenance before interpreting
Save the source URL, review date, stated effective date, and the exact business scope you examined. Compare the same section across versions. A page redesign, retrieval failure, or renamed legal entity should not automatically become an adoption or removal event.
Triangulate and document gaps
A job board and a disclosure may corroborate different parts of a company’s stack. They do not necessarily cover the same entity or business unit. Record disagreement and missing sources explicitly. Escalate the research question rather than filling gaps with assumptions.
The source-map ratings below are editorial heuristics, not measured confidence probabilities or promised collection latency.
A public job board supports an ATS observation. A subprocessor disclosure identifies a provider that may process data for particular services. A vendor customer story describes a published relationship. These sources have different scopes and are labeled separately.
Counts cover the records on these pages, not the whole market. No observation in our covered sources does not mean a company does not use a vendor. Source recency and unresolved conflicts affect confidence; observations do not establish spend, renewal timing, or customer churn.
