What is Clearbit?
Clearbit (now Clearbit by HubSpot and increasingly delivered as Breeze Intelligence inside HubSpot) is a B2B data provider and go-to-market intelligence platform. It enriches leads, contacts, and accounts with over 100 firmographic, technographic, and intent attributes drawn from hundreds of public and proprietary sources, giving marketing, sales, and revenue teams a complete, always-fresh view of their ideal customers.
The platform originated as a developer-centric set of APIs for email and company lookups and has evolved into a full data activation layer that sits on top of CRMs and marketing automation systems. Clearbit’s Enrichment, Reveal (IP-to-company identification), Forms, Audiences, and Advertising capabilities power use cases such as form shortening, precise lead scoring and routing, ABM targeting, website personalization, and account-based retargeting across Facebook and Google.
Founded in 2015 and headquartered in San Francisco, Clearbit raised roughly $17M in venture funding and grew to serve more than 1,500 business customers before being acquired by HubSpot in late 2023 for around $150M. Since the acquisition, Clearbit has been integrated as a wholly owned subsidiary and is being folded into HubSpot’s customer platform as Breeze Intelligence, with free standalone tools like Clearbit Connect, the free Slack integration, and the free platform sunset on April 30, 2025 and the public Logo API shut down in December 2025.
Today, new buyers primarily access Clearbit’s capabilities through HubSpot (via Breeze Intelligence credit packs and add-ons), while existing Clearbit customers continue to run enrichment, reveal, and advertising workflows against Salesforce, Marketo, Segment, and other systems. Clearbit remains positioned as a premium, API-friendly data backbone for B2B demand generation and revenue teams that prioritize high-quality company data, intent signals, and deep HubSpot integration over low-cost, contact-heavy databases.

A balanced view of Clearbit, drawn from public reviews and product research.

Who Clearbit is for
A strong fit for
B2B companies (especially SaaS and digital-first businesses) running HubSpot, Salesforce, Marketo or similar stacks that need high-quality company-level data, intent signals, and flexible APIs to drive personalized marketing, ABM programs, and data-driven sales processes at scale.
Probably not for
Very small teams or freelancers looking mainly for cheap contact lists or an all-in-one outreach tool, organizations that are not on HubSpot and want a standalone platform, or buyers whose primary need is full sales engagement (dialer, sequences, inbox) rather than back-end data enrichment.
How Clearbit compares
Compared with broad, contact-heavy data clouds like ZoomInfo or 6sense, Clearbit focuses more on high-quality company-level enrichment, intent signals and activation workflows than on being the single largest phone-and-email database. Its Sweet spot is modern B2B teams that want precise firmographics, technographics and website intelligence wired directly into HubSpot and Salesforce, with strong APIs for custom use cases.
Against newer players like Apollo.io and Lusha, Clearbit is typically more expensive but offers richer attributes, better HubSpot alignment and more mature security and governance, making it attractive for mid-market and enterprise buyers willing to pay for data quality and platform depth. However, Clearbit’s post-acquisition shift into Breeze Intelligence and its credit-based pricing mean non-HubSpot customers and smaller teams may find better value and lower friction with alternatives that remain fully standalone and more transparent on pricing.
Tool research is the easy part. Someone still has to build the lists, write the copy, make the calls, and book the meetings.
