What is company website?
A company website URL (e.g. acme.com) is one of the most reliable enrichment inputs because the domain is unique. It deduplicates accounts (same company, multiple legal names) and matches cleanly against B2B databases. From a domain you resolve company name, LinkedIn page, headcount, industry, tech stack, hiring trends, funding history and 50+ firmographic fields.
In the context of company contact email-based prospecting, company website sits downstream: you start from the company contact email as your lookup key, the resolver maps it to the matching record in the source graph, and the company website value is returned as part of the enrichment payload. The accuracy of the company website you get back depends on how cleanly your company contact email input identifies the underlying entity.
