Excellent
Brent score, out of 5
Apollo.io combines a database of about 240 million contacts and 30 million companies with sequences, a dialer, enrichment and AI agents. For startups and small sales teams it can replace a data tool and an outreach tool at once, and the free plan has no time limit. Watch the credit system: credits are pooled, reset every billing cycle and never roll over.

Best for
- Founders and SDRs doing their own outbound prospecting

- Teams that enrich CRM records in HubSpot or Salesforce

- Buyers who want simple, fixed pricing without credits
Outbound sales eats time before you even write an email. You hunt for the right people, guess their addresses, copy them into a spreadsheet, then into an email tool, then into the CRM. By the time the list is ready, half the day is gone.
Apollo.io puts the contact data, the outreach and the follow-up in one place. You filter a database of around 240 million people, add them to a sequence, call from the dialer, and sync it all to your CRM. Its AI agents can now research accounts and draft outreach for you.
Here is how Apollo works, how the credits really behave, and when a different tool fits better.
What is Apollo.io?
Apollo.io is a go-to-market platform that joins B2B contact data with sales engagement. You search for contacts and companies by role, industry, size and buying signals such as job changes, intent and website visits. You then reveal emails and phone numbers using credits, add people to multi-step sequences, and call them from the parallel dialer. Waterfall enrichment fills gaps from several sources, and AI agents can build lists, write outreach, follow up and book meetings based on your ideal customer profile.
