Our take on Apollo.io

Apollo pairs a contact and account database with outreach, dialing, and agents that research accounts and write outreach. The free Starter plan has no time limit, which in our view makes it an easy way to test fit before paying. Apollo says plans are for internal business use only, so agencies reselling data should read the terms.

Our take on ZoomInfo

ZoomInfo offers firmographic, technographic, and intent data with CRM sync, routing, and enrichment. Pricing depends on credits, add-ons, and integrations, so in our view it suits teams with budget and volume. A free trial is offered.
