  • How does Clearbit's data quality compare to ZoomInfo?

    Clearbit and ZoomInfo both provide high-quality data enrichment solutions. At Clearbit, we use machine learning and highly-trained QA to turn billions of signals into real-time intelligence. Our data points are refreshed as soon as a change is detected. Similarly, ZoomInfo uses AI and a team of data scientists to verify the quality of their data.

    The Workflow Pro performed a third-party analysis of Clearbit vs ZoomInfo's data enrichment solutions and found “Clearbit is the best enrichment tool overall when it comes to populating the most records and being the most accurate at populating these records.”

  • Is Clearbit's database as large as ZoomInfo?

    Clearbit's database features over 50 million company records. We take a conservative approach to how we quantify our data assets – one that focuses on quality over quantity. For example, we exclude all personal emails and combine multiple company domains into a single record. Other companies may use a different methodology to calculate the size of their databases.

  • Does Clearbit offer a list building tool?

    Yes, although we take a slightly different approach than other companies. We're not big fans of people 'cold-calling' our mobile phones (and suspect you aren't either). Our approach to list-building is based on helping you find key contacts at companies that have shown some intent or engagement with your business – and making sure we can provide emails with high-deliverability confidence. We call our solution Capture.
