Overview

Clearbit is a comprehensive B2B data and intelligence platform that has revolutionized how modern sales and marketing teams understand, identify, and engage with their target accounts. At its core, Clearbit aggregates and synthesizes data from over 250 public and proprietary sources to deliver the most accurate, real-time information about companies and the people who work at them. Unlike traditional data providers that offer static databases requiring manual updates, Clearbit's machine learning algorithms continuously refresh company profiles, ensuring that sales representatives always have access to current firmographic data, technology stack information, funding status, and organizational changes. The platform serves as the foundational data layer for go-to-market teams, seamlessly integrating with CRM systems like Salesforce and HubSpot, marketing automation platforms, and custom applications through robust APIs. When a new lead enters your system, Clearbit instantly enriches that record with over 100 data points including company size, industry classification, annual revenue estimates, technologies used, social media presence, and key decision-maker information. This enrichment happens in milliseconds, enabling real-time lead scoring, routing, and personalization at scale. Clearbit's Reveal product identifies anonymous website visitors by matching IP addresses to company profiles, transforming unknown traffic into actionable sales intelligence. Marketing teams leverage this capability to personalize website experiences, trigger targeted advertising campaigns, and alert sales teams when high-value accounts are actively researching solutions. The platform's Prospector tool enables sales development representatives to build targeted prospect lists based on ideal customer profile criteria, accessing a database of over 350 million contacts at 40 million companies worldwide. What truly differentiates Clearbit is its commitment to data quality and freshness. The platform employs sophisticated verification processes and machine learning models trained on billions of data points to maintain accuracy rates exceeding 95%. For enterprise organizations, Clearbit offers custom data solutions, dedicated support, and advanced security features including SOC 2 Type II compliance and GDPR-ready data handling. Whether you're a startup looking to identify your first hundred customers or an enterprise seeking to optimize a complex go-to-market motion, Clearbit provides the data infrastructure necessary to compete in today's intelligence-driven sales environment.

Key Features

Data Enrichment API

Clearbit's Data Enrichment API automatically appends over 100 firmographic, technographic, and demographic attributes to any email address or domain in real-time. When a prospect fills out a form with just their email, the API instantly returns company name, size, industry, funding status, technologies used, social profiles, and dozens of other data points. This eliminates lengthy forms that kill conversion rates while giving sales teams the context they need to prioritize and personalize outreach. The API processes requests in under 200 milliseconds, enabling real-time lead scoring and routing decisions without any perceptible delay to the user experience. Reduce form fields by 80% while capturing 10x more data about every lead, dramatically improving both conversion rates and sales intelligence.

Reveal (Website Visitor Intelligence)

Clearbit Reveal transforms anonymous website traffic into identified company profiles by matching visitor IP addresses against Clearbit's proprietary database of corporate IP ranges. When a visitor from a target account browses your pricing page or product documentation, Reveal identifies the company and can trigger real-time alerts to sales teams, personalize website content, or add the account to retargeting audiences. The system identifies companies with 85%+ accuracy and provides full firmographic profiles including industry, size, location, and technology stack—turning your website into an intent data source. Convert anonymous website visitors into qualified pipeline by identifying which target accounts are actively researching your solution.

Prospector (Contact Database)

Clearbit Prospector provides access to a continuously updated database of over 350 million verified business contacts at 40 million companies worldwide. Sales teams can build highly targeted prospect lists using advanced filters including job title, seniority level, department, company size, industry, technology usage, and geographic location. Unlike static databases, Prospector's contacts are verified through multiple sources and updated as people change roles, ensuring deliverability rates above 95%. The tool integrates directly with Salesforce and Outreach, enabling one-click list building and immediate sequence enrollment. Build laser-targeted prospect lists in minutes instead of hours, with confidence that contact information is accurate and current.

Advertising Audiences

Clearbit Advertising enables B2B marketers to build precision-targeted advertising audiences based on firmographic and technographic criteria rather than relying on platform-native targeting. Create custom audiences of companies using specific technologies, within certain revenue ranges, or matching your ideal customer profile, then sync these audiences directly to Facebook, Google, and LinkedIn advertising platforms. The system also enables retargeting of identified website visitors at the company level, ensuring ad spend focuses on accounts most likely to convert rather than broad demographic segments. Reduce wasted ad spend by 40-60% by targeting only companies matching your ideal customer profile across all major advertising platforms.

Salesforce Integration

Clearbit's native Salesforce integration automatically enriches leads, contacts, and accounts with fresh data as records are created or updated. The bi-directional sync ensures that Clearbit data flows into standard and custom Salesforce fields, powering lead scoring models, assignment rules, and reporting dashboards. Sales teams see enriched data directly within their existing workflow, with no context switching required. The integration also enables Salesforce-triggered prospecting, automatically finding new contacts at accounts when opportunities reach certain stages or when existing contacts go dark. Eliminate manual data entry and research time while ensuring every Salesforce record contains the intelligence needed for effective selling.
