Apollo is genuinely impressive on three fronts:
- US-centric database depth. If you sell into the United States, Apollo's contact graph is one of the most complete in the industry — direct dials, verified emails, org charts.
- Freemium accessibility. Apollo's free tier with limited credits is a friendly on-ramp for solo founders testing the waters.
- Integrations ecosystem. Mature integrations with Salesforce, HubSpot, Outreach, Salesloft and most major CRMs.
