Common Questions
Most tools detect web technologies like CMS, analytics, marketing automation, and CDNs. Deeper tools detect internal systems through job postings, integrations, and partnership data. Enterprise tools add contract and spend data.
Web-detected technologies are 85-95% accurate. Internal systems inferred from job postings or partnerships are less reliable. Always verify critical data points manually for important accounts.
Build lists of companies using competitor technologies. Target accounts using complementary tools you integrate with. Find companies that recently added or removed specific technologies as timing signals.
Yes. Technographics is most powerful combined with firmographics, intent data, and contacts. Platforms like ZoomInfo bundle these together. Otherwise integrate via CRM enrichment.
