clearbit

Clearbit is a data and intelligence company that provides real-time B2B information to support marketing, sales, and risk teams. Through APIs and prebuilt integrations, Clearbit offers services such as data enrichment, prospecting, and website intelligence to help identify and qualify leads, personalize experiences, and reduce manual research.

Founded in 2014 by a team led by Alex MacCaw, Clearbit expanded rapidly, building a suite of tools designed to augment customer data across CRM, marketing automation, and ad platforms. The company emphasizes developer-friendly APIs and cloud-based delivery, enabling businesses to embed data enrichment into their workflows and applications without large internal data teams.

Core products include Clearbit Enrichment (automatically fills out company and contact details from partial information), Clearbit Prospector (lead discovery with filters and intent signals), Clearbit Reveal (visitors to a site are identified in real time), and Clearbit Connect (CRM/browser extension for Gmail/Outlook). It integrates with major platforms such as Salesforce, HubSpot, Marketo, and ad networks, and supports data enrichment for emails, accounts, and leads, boosting segmentation and targeting.

Data sources include publicly available information, partner data, and user-provided content, with privacy controls and compliance measures. Clearbit provides opt-out options and adheres to GDPR and CCPA requirements in many jurisdictions. As with data brokers, accuracy and governance are ongoing considerations for customers who rely on enrichment for decision-making and risk assessment.
