The core technology involves aggregating, cleaning, and structuring vast amounts of public and proprietary data. Its main purpose is to transform basic contact or company information into rich profiles. This helps sales and marketing teams personalize outreach and prioritize leads. We found it significantly reduces manual data entry and research time. It integrates with CRMs and marketing automation platforms.

  Clearbit Prospector allowed us to build targeted lists of leads based on specific criteria. We filtered by industry, employee count, and technology used. We found the results offered accurate contact details, including email addresses. This streamlined our lead generation efforts significantly.

• Forms

  We integrated Clearbit Forms to shorten our website forms. We observed it auto-populating fields like company size and industry after a visitor entered their email. This reduced friction for conversions. It improved our lead capture rates without asking too many questions.
