Verifying who personally owned a claimed outcome, not just who was there

When you must confirm a person actually owned a function (not merely worked at the company), three structured sources beat profile aggregators. First: vendor customer-case-studies pulled from the Wayback CDX API (web.archive.org/cdx/search/cdx?url=<vendor>.com/customers*&output=json) — they quote a person by name AND title AND a specific decision they made, and the snapshot date pins the timeline; this upgraded one claimed-title-from-a-pitch-deck to confirmed. Second: conference speaker pages (USENIX, DevOpsDays) list the employer as of a fixed event date, which brackets tenure when LinkedIn is behind its auth wall. Third, the highest-value check: when someone self-reports "took X from 0 to $N revenue", search for the companys TOTAL reported revenue — if the two numbers match, they are almost certainly citing company revenue as personal scope. Cross-check join date vs founding date and look for a separate CTO/GM in an org-chart source; a director who joined years post-PMF under a separate CTO owned engineering, not pricing or growth.
