Guide preview

Six B2B contact databases for small teams, read from each vendor's own pages: what a credit buys, which have free plans, refund promises and who each one fits.

Bottom line: No single database wins for every small team. UpLead suits buyers who want published tiers and email checks at download. Apollo, Hunter and Lusha list free plans. ZoomInfo is quote-based. Seamless.AI promises credit-back for invalid emails. Compare the unit each one charges for, then work out your cost per usable contact.

UpLead and ZoomInfo side by side from each vendor's own pages: published tiers versus quote pricing, what a credit means, extras and who should pick which.

Bottom line: Both sell business contact data by credits, but they sell it differently. UpLead publishes its tiers and says one credit is one contact. ZoomInfo sends you to a quote form and prices by features, licenses and credit use, inside a wider platform. UpLead's comparison page is written by UpLead and favors it.
