Clearbit

Clearbit (now part of HubSpot) is a B2B data and enrichment platform that helps companies enrich their contact and account records with accurate company and person details, identify website visitors, and power smarter sales and marketing. By turning a single piece of information — like an email or a company domain — into a rich profile of firmographic and contact data, Clearbit helps teams understand who their leads and customers are, qualify and route them effectively, and personalize their outreach and marketing.

The platform's core capability is data enrichment: given limited information, it appends details such as company size, industry, location, role and more, filling in the gaps in your CRM and marketing systems so records are complete and useful. Beyond enrichment, Clearbit offers capabilities like identifying anonymous website visitors (revealing which companies are showing interest), real-time enrichment of form submissions to shorten forms and improve data quality, and intelligence that supports lead scoring, segmentation and targeting. This data foundation helps sales and marketing teams work more precisely and efficiently.

Clearbit is widely used by B2B sales and marketing teams that depend on accurate, complete data to qualify leads, personalize campaigns, route prospects to the right reps, and understand their pipeline and audience. Its integration into the broader sales and marketing stack — including its connection to HubSpot — makes enriched data available where teams already work. As B2B go-to-market increasingly relies on good data for targeting and personalization, enrichment and intelligence platforms are an important part of the stack. For B2B teams that want to enrich their data, identify interested companies and power more precise, personalized sales and marketing, Clearbit offers a powerful, well-established and widely-trusted solution — used in accordance with applicable privacy regulations.
