Pricing

Apollo has a genuinely free plan with limited credits and paid tiers from roughly $49/seat/mo, which is why it has become the default starting point for SMB and mid-market teams. ZoomInfo does not publish pricing: it sells custom annual contracts that typically start around $15k/yr and scale with seats and data packages, with no self-serve option. The two tools sit at opposite ends of the spending spectrum.

Verdict: Apollo for affordable, transparent, self-serve pricing; ZoomInfo only if you have the budget and procurement appetite for an enterprise contract.

Features

ZoomInfo is the enterprise standard for B2B data, pairing the deepest US firmographics and org charts with strong intent signals and a full go-to-market platform. Apollo bundles a 275M+ contact database with sequencing, a dialer, and a Chrome extension, so reps can find and contact prospects in one place. ZoomInfo wins on raw data depth and buying-committee insight; Apollo wins on breadth of workflow for the money. Both, honestly, are US-first: for Europe neither is the best pick, and teams selling into EMEA should look at Cognism for GDPR-compliant, phone-verified data, with Pipecorn as an affordable European alternative.

Verdict: ZoomInfo for data depth and intent; Apollo for an all-in-one prospecting and engagement workflow.

Integrations

Both connect to the core sales stack. Apollo offers around 100 integrations including Salesforce, HubSpot, Gmail, Outreach, and Zapier, with a strong LinkedIn Chrome extension. ZoomInfo has roughly 70 integrations across Salesforce, HubSpot, Outreach, Salesloft, and Marketo, plus robust enrichment and CRM-hygiene tooling that larger orgs rely on. Apollo edges ahead on count; ZoomInfo on enterprise-grade data sync and cleansing.

Verdict: Apollo for breadth and a great extension; ZoomInfo for enterprise enrichment and CRM hygiene.

Ease of use

Apollo is self-serve and intermediate in complexity: you can sign up, build a list, and launch a sequence the same day. ZoomInfo is more advanced, with a heavier platform that rewards configuration but needs onboarding and admin attention, and its seat-based pricing and upsell motion add friction. For a team that wants to move fast without procurement, Apollo is the lighter lift.

Verdict: Apollo for quick, self-serve adoption; ZoomInfo for teams ready to invest in a full platform rollout.
