Methodology: sponsor listings are collected from each conference's own website and de-duplicated to a canonical company (subsidiary brands like Google Cloud are counted where events list them separately). A company's count is the number of distinct conference editions listing it as a sponsor. Media partners, community partners of record, job boards, and event-tooling vendors are excluded where identified.
