Apollo.io screenshot

Apollo.io is a B2B contact database welded to an outbound execution tool, which is what separates it from a pure data vendor. You filter companies and people by title, headcount, industry, geography and intent signals, reveal work emails and mobile numbers, then push those contacts straight into multi-step sequences, a built-in dialer or your CRM without exporting anything. Around that it records and transcribes sales calls, scores leads, routes inbound form fills, identifies anonymous website visitors and re-enriches stale CRM records on a schedule, including when a contact changes job. A Chrome extension does the same reveal-and-sequence job from LinkedIn. It is built for teams running high-volume outbound, mainly in the US — the further you get from that, the weaker the value.

Comparee rates Apollo.io 85/100 in Sales & Lead Generation — based on catalog data as of August 2026. Methodology.

Pros & cons

✓ Pros

  • Database and outbound sequencing in one product, so contacts never need exporting to a separate sending tool
  • Intent signals let you prioritise accounts that are already showing buying behaviour
  • Waterfall enrichment falls through several data sources to fill a missing field
  • Built-in dialer with call recording and AI call insights
  • Automatic CRM enrichment, including job-change updates when a contact moves company
  • Website visitor identification and inbound lead routing
  • Deliverability tooling with mailbox warmup, and a genuinely usable free plan with no card required

✗ Cons

  • Data accuracy is the dominant complaint — outdated titles, people who left the company a year or two ago, and bounce rates far above a healthy threshold
  • Accuracy is worst outside the US, so European and small-company data needs verifying before you send
  • The listed plans are for internal use only: you may not use the data to power a product, share it with customers or resell it without a separate agreement
  • The top self-serve tier has a three-seat minimum, so its real entry price is triple the advertised per-seat number
  • Export credits are consumed every time a contact leaves Apollo — CSV, CRM sync or API — and unlimited plans are still capped by fair use
  • No refunds on mid-term downgrades and cancellation only takes effect at the end of the billing cycle
  • GDPR exposure in Europe is contested, with public complaints from professionals about being listed without consent
