B2B contact, company and org chart data with intent signals, enrichment and AI features that suggest which accounts to work next.
ZoomInfo is one of the larger B2B data providers. Its core is a database of companies and the people who work there, with titles, reporting lines, emails, direct dials and company details such as size, revenue band and technologies in use.
Sales and marketing teams use it to build target account lists, find the right contacts inside an account, keep CRM records up to date through enrichment, and spot accounts showing research activity on topics they care about. The platform has grown to include engagement, conversation and workflow features, and its AI assistant pulls account context and suggests next steps.
It suits teams that sell to many companies and need broad coverage, especially in North America. Contract terms are usually annual and built around seats and data credits, so ask how credits are counted, test coverage in your own segments, and check how the data is collected for the regions you sell into.
