What is company tech stack?
Company tech stack (or technographics) is the inventory of software an account runs on its public website + product (e.g. uses Salesforce, HubSpot, Stripe, Segment, Datadog). BuiltWith and Wappalyzer are the canonical sources; some B2B databases (Cognism, ZoomInfo) layer in CRM-system + ATS detection beyond what's publicly inferrable.
For B2B teams operating from a list of company website values, company tech stack is typically among the first 3-5 fields enriched on a fresh list. It feeds personalisation, segmentation, and routing logic - all of which need company tech stack to be present and current before any downstream automation runs.
