Best B2B Contact Data Providers in 2026

Finding contact data for business outreach involves more than checking how many records a provider lists. Compared on API access, contact database size, direct-dial data, intent data, and technographic filters, these providers also differ in monthly export limits. Apollo, Lusha, and LeadIQ are among the options to compare for the data and filtering details shown. Consider whether API access fits your workflow, and how much exporting you expect to do. Free-plan availability and paid-from pricing add plan details to weigh alongside the listed data features.
