Exellius offers (Reference, Alternative) — Stated anchors: 100M+ verified contacts at a claimed 98% accuracy rate, global coverage across 190+ countries, and a technology-stack layer covering the digital footprint of companies in those geographies plus a dedicated Amazon seller database. Implied total: contact records in the low hundreds of millions joined to a technographic layer of company-technology-presence observations plausibly in the billions of company-technology pairs (companies in the corpus x detectable technology categories per company), refreshed continuously.

Primary buyer use: technology-based account segmentation and targeting for vendors selling into companies that run a given stack, market sizing of installed bases, and territory expansion. Information-frontier use: the install base itself is a census of enterprise technology adoption - a measure of market penetration per technology vendor across geographies and firm-size bands. The genuinely high-value derivative is the change history: if install-base snapshots are retained over time, technology additions and removals become adoption and churn curves per vendor, giving a direct read on displacement, seat-expansion potential and renewal risk for listed software vendors, independent of their own disclosed metrics. The Amazon seller layer additionally supports e-commerce channel and third-party marketplace penetration analysis.
