B2B Data Providers

ZoomInfo

Enterprise B2B data and go-to-market intelligence platform with intent and enrichment.

★★★★★4.5 on G2 (9,000+ reviews)

Overview

ZoomInfo is the category-defining enterprise data provider, combining one of the largest B2B contact and company databases with buyer intent, technographics, org charts, and workflow automation. Its GTM and SalesOS tiers bundle enrichment, intent signals, and a light engagement layer, while data hygiene and CRM enrichment run through platform APIs. Coverage and depth are best in class, especially for US enterprise accounts, but pricing is quote-only, contracts are annual, and the platform is heavy to administer. Best suited to enterprise revenue teams with RevOps to run it, though a newer ZoomInfo Lite targets smaller teams.

Best for: The pick when an enterprise revenue team needs the deepest US B2B data, intent signals, and RevOps muscle to run it.
