San Francisco-based Clearbit provides a suite of business intelligence APIs that enrich company and contact data for enterprise sales and marketing teams.

Operating on an API-based business model, the company scaled to hundreds of employees and generated tens of millions of dollars in annual recurring revenue. Clearbit secured early financial backing from notable venture firms and angel investors, including First Round Capital, SV Angel, and Intercom executive Eoghan McCabe. In January 2025, the business was acquired by HubSpot to integrate these data enrichment capabilities directly into its broader software platform. The company was originally founded in 2015 by former Stripe engineer Alex MacCaw alongside Amit Vasudev and Matt Sornson.

# Clearbit: B2B Data Intelligence Platform
Clearbit is a B2B data intelligence and enrichment platform that provides real-time company and contact information to power sales, marketing, and customer success operations.[1] The platform helps businesses make informed decisions by delivering accurate, up-to-date insights on prospects and accounts, enabling teams to identify high-fit leads, personalize outreach, and optimize go-to-market strategies.
The company serves mid-market and enterprise B2B organizations across industries, with particular strength among SaaS companies, marketing teams, and sales departments.[3] Clearbit's core value proposition centers on solving a critical business problem: data accuracy and lead quality. Rather than building from scratch, Clearbit enriches existing customer records by appending 100+ business data attributes sourced from over 250 public and private data sources, transforming incomplete contact information into actionable intelligence.[2][5]
Clearbit was founded with a mission to create the freshest and most accurate B2B data available. The company built its reputation over six years through continuous improvements to its dataset and machine learning algorithms, positioning itself as the proven industry leader in data quality.[5] This focus on data excellence and reliability became the foundation for its growth trajectory.
In a significant milestone, Clearbit joined HubSpot, becoming part of the HubSpot AI product suite (also referred to as Breeze Intelligence).[4][6] This acquisition integrated Clearbit's data capabilities directly into HubSpot's broader B2B customer platform, expanding its reach and embedding its enrichment technology into one of the world's most widely used CRM systems.
Clearbit operates at the intersection of two powerful trends: the increasing importance of first-party data in a privacy-conscious world and the growing sophistication of AI-driven sales and marketing automation. As third-party cookies disappear and regulations like GDPR reshape data practices, businesses need reliable sources of verified B2B intelligence—exactly what Clearbit provides.
The platform's integration into HubSpot amplifies its influence across the B2B ecosystem. By embedding data enrichment directly into the world's most popular CRM, Clearbit democratizes access to sophisticated intelligence that was previously available only to large enterprises. This positions the company at the center of how modern B2B teams operate: identifying prospects, scoring leads, personalizing outreach, and measuring campaign effectiveness.
The timing is particularly significant as B2B companies increasingly recognize that data quality directly impacts revenue. Sales and marketing teams waste substantial resources on inaccurate contact information and poor lead targeting. Clearbit's solution addresses this fundamental inefficiency, making it essential infrastructure for go-to-market teams.
Clearbit's acquisition by HubSpot validates the strategic importance of data enrichment in the modern B2B stack. As the company evolves within HubSpot's ecosystem, its influence will likely expand beyond enrichment into predictive analytics, buyer intent signals, and AI-powered account intelligence—helping teams not just understand who their prospects are, but predict when they're ready to buy.
The future of B2B sales and marketing belongs to organizations that can combine clean data with intelligent automation. By anchoring HubSpot's platform with industry-leading data infrastructure, Clearbit is positioned to shape how the next generation of B2B companies compete and grow.
Clearbit has raised $17.0M across 2 funding rounds. Most recently, it raised $15.0M Series A in March 2019.
