What is company industry?
Company industry is the vertical classification of an account (e.g. "Software", "Financial Services", "Manufacturing"). It's a primary ICP-fit signal and the standard segmentation axis for territory plans. LinkedIn maintains the most consistent industry taxonomy among free sources; specialised B2B databases (ZoomInfo, Cognism) provide more granular sub-industry codes.
In the context of lead email-based prospecting, company industry sits downstream: you start from the lead email as your lookup key, the resolver maps it to the matching record in the source graph, and the company industry value is returned as part of the enrichment payload. The accuracy of the company industry you get back depends on how cleanly your lead email input identifies the underlying entity.
