How this is collected
VendorStacks runs a multi-source extraction pipeline over a company's public web presence: crawling, rendering JavaScript pages and PDFs, and matching a deterministic vendor taxonomy against what the company itself publishes. Nothing is inferred from tracking pixels or guessed from job posts — if we say a company uses Sinch, we can show you the sentence that says so. How it works →
