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.
In the context of LinkedIn company URL-based prospecting, company tech stack sits downstream: you start from the LinkedIn company URL as your lookup key, the resolver maps it to the matching record in the source graph, and the company tech stack value is returned as part of the enrichment payload. The accuracy of the company tech stack you get back depends on how cleanly your LinkedIn company URL input identifies the underlying entity.
