Available Data Points - Acquiring Detailed Prospect Information

Apollo's enrichment capabilities offer a more extensive range of data points, notably in company insights like buying signals and tech stacks, which are not commonly found in other platforms.

Moreover, integrating Apollo with Bardeen can enhance your data enrichment processes, automating workflows and enriching leads in other apps effectively. Check out this playbook for enriching contact information using Apollo.io to see how it can transform your data handling.

If your needs lean towards comprehensive background information and actionable company insights for a more informed outreach, Apollo provides a significant advantage over ZoomInfo.


Detailed work history, contact stage, and last 12 months engagement data for a contact in Apollo.

Apollo provides an extensive range of data points for contacts and companies, going beyond standard information like email and phone numbers. The breadth of Apollo's platform stands out, capturing a large number of contacts and companies with detailed insights.

Key data points available in Apollo:

  • Work History: Detailed work history for contacts, including job titles, companies, and tenure
  • Contact Stage: Engagement status and contact owner information
  • Engagement: 12-month engagement history, showing inbound and outbound interactions
  • Company Insights: Buying signals, tech stack, and announcement triggers (though level of detail may vary)

While Apollo offers extensive work history and company details, it provides less data from social platforms compared to some competitors. However, the unique company insights like buying signals and tech stack, when available, can be valuable for personalizing outreach, even if the granularity of the data may not always be sufficient.

Enrichment Integrations - Optimize CRM and Sales Tool Connectivity

When comparing the integration capabilities of Apollo and Zoominfo for enrichment services, Apollo offers a more straightforward approach for CRM and sales engagement tools, specifically supporting direct integrations with major platforms like HubSpot and Salesforce. This is complemented by its ability to connect with Outreach and Salesloft, catering well to users needing seamless integration with these specific tools.

Apollo's CRM Integration Options

Zoominfo, on the other hand, does not provide direct CRM integrations but does offer the flexibility of connecting with AWS and Google Cloud through APIs. This could be beneficial for tech-savvy teams that require customization and are using these cloud services extensively.

For teams looking for direct and hassle-free CRM integrations with some of the most commonly used platforms, Apollo might be the more appealing choice. However, if your team is proficient in leveraging cloud technologies and prefers a more flexible, API-driven approach, Zoominfo's capabilities with AWS and Google Cloud are impressive.

To further enhance data enrichment and integration across your preferred tools, consider using Bardeen, which connects data from platforms like Apollo to your CRM or sales engagement tool of choice. Bardeen's ability to automate workflows with Apollo.io and other platforms can significantly boost your productivity and data management efficiency.
