An incredibly powerful B2B data intelligence engine that instantly enriches anonymous web traffic into highly detailed corporate leads.

About Clearbit

Clearbit (recently acquired by HubSpot) is the undisputed industry standard for B2B data enrichment. In modern digital marketing, a company might know that 'john@example.com' signed up for a newsletter, but they have no idea if John is a student or the CEO of a Fortune 500 company. Clearbit's massive AI data engine solves this instantly.

When an email is captured, Clearbit's API instantly scans the web and enriches that single email address with over 100 data points: John's job title, his company's annual revenue, the software stack his company uses, and their exact office location. This allows marketing teams to instantly and automatically route high-value leads directly to the sales team while sending low-value leads to an automated email sequence.

Furthermore, Clearbit Deanonymize uses IP tracking and AI to identify the exact companies browsing a B2B website, even if the user never fills out a form. A sales rep can see that 'Nike' spent 30 minutes on the pricing page today, allowing for highly targeted, proactive outreach.
