Clearbit

Clearbit, now operated as "Clearbit by HubSpot" following HubSpot's acquisition, is a B2B data enrichment platform that converts unstructured lead, contact, and account information into precise, standardized data sets to support go-to-market efforts. It enriches data across all countries and languages, provides real-time lead scoring and routing using industry classifications (NAICS, GICS, SIC codes), maps corporate hierarchies to identify parent companies and subsidiaries, adds IP intelligence to detect anonymous website visitors and buying-intent signals, and shortens forms dynamically by auto-populating fields already known from an email address. No pricing is shown on the main page; as part of HubSpot's platform, access and cost likely tie into HubSpot's existing plans. Good fit for a sales or marketing team using HubSpot that wants lead and account data automatically enriched and scored, rather than manually researching each contact.
