How this is measured
Companies disclose their own vendors — subprocessor lists, trust centres, security pages and privacy documentation name third parties by regulation or by policy. VendorStacks crawls that public surface, renders JavaScript pages and PDFs, and matches a deterministic taxonomy of 24 categories against what the company itself published. No tracking pixels, no DNS fingerprints, no guessing from job posts. Every match keeps the sentence it came from, which is why a share figure on this page can be traced back to a specific document on a specific company's site. How it works →
Frequently asked questions
- Which data enrichment vendor is most widely used?
- ZoomInfo appears in 28 of the 56 companies we have a data enrichment vendor for — 50% of them. The next four together account for 73.2%.
- How do you know a company uses a data enrichment vendor?
- Because the company published it. Subprocessor lists, trust centres, security pages and privacy documents name vendors by law or by policy. We extract the vendor name and keep the sentence it came from, so every match has a quotable source rather than an inferred fingerprint.
- How current is this data?
- The most recently refreshed company in this category was updated 2026-08-25. Disclosure pages change slowly — usually when a vendor is added or dropped — and we re-scan on a rolling basis.
- Can I get the full list rather than a sample?
- Yes. One API call returns every company in this category with its vendors, the evidence row, and the source URL. A free key includes 25 credits and each lookup costs one.
