For prospecting workflows that depend on business contact information, B2B data providers differ in both coverage and access. Compare API access, contact database size, direct-dial data and intent data, alongside technographic filters and monthly export limits. Free plans and paid-from pricing offer additional context for evaluating access and cost. The ranking starts with Apollo, LeadIQ and Lusha, followed by ContactOut and Wiza; Seamless.AI is another early entry. Consider which data attributes your team needs and how it will use or export them, then compare providers across the listed criteria.
