Clearbit vs ZoomInfo

If you're comparing Clearbit and ZoomInfo, you're asking one question: do you need a data enrichment layer built inside your CRM, or a go-to-market intelligence platform that spans prospecting, intent, engagement, and orchestration across any CRM and any tool?

The comparison shifted in December 2023, when HubSpot acquired Clearbit and folded it into HubSpot as Breeze Intelligence. Clearbit is no longer a standalone product. It exists only inside HubSpot, serving HubSpot customers. If you use Salesforce, Dynamics, or any other CRM, Clearbit is not an option.

Before evaluating these platforms, three questions will focus your decision:

• Is your team fully committed to HubSpot as your CRM, or do you need a platform-agnostic solution?

• Do you need a standalone prospecting database, or do you only need to enrich records you already have?

• Do you need conversation intelligence, multi-channel orchestration, or a seller workspace, or is enrichment and visitor identification enough?

Here is what the evaluation comes down to:

Clearbit (Breeze Intelligence) enriches your HubSpot CRM records with firmographic, demographic, and technographic data from over 200 million company and buyer profiles. It identifies anonymous website visitors at the company level, shortens forms to improve conversion rates, and keeps records fresh with automatic monthly updates. For HubSpot users who primarily need enrichment and visitor identification, it fits naturally, especially since basic enrichment is included in all Starter+ seats at no extra credit cost. The trade-off: no standalone API, no prospecting database, no contact-level data discovery, and no availability outside HubSpot.

ZoomInfo is an all-in-one AI GTM Platform built on a large B2B data foundation: 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails. Its GTM Context Graph processes 1.5B+ data points daily by fusing ZoomInfo's B2B data with your CRM records, conversation transcripts, and behavioral signals into a unified intelligence layer. That context feeds AI that shows not just what happened, but why it happened, and which actions to take next. Sellers work from GTM Workspace, marketers and RevOps build plays in GTM Studio, and developers access the same intelligence through APIs and MCP in any front-end.

Both platforms handle B2B data enrichment, but they serve fundamentally different needs. Clearbit is a data layer for HubSpot. ZoomInfo is a GTM platform for the entire revenue organization.

The core difference: Enrichment layer vs. full GTM platform

Clearbit started in 2014 as an independent, API-first B2B data enrichment company built for developers. It offered clean REST APIs that any tech stack could use, serving over 400,000 users with data on 20M+ companies and 500M+ decision-makers sourced from 250+ data sources. That changed in December 2023 when HubSpot acquired it and rebranded the capabilities as Breeze Intelligence at INBOUND 2024.

Today, Clearbit exists exclusively inside HubSpot. The standalone APIs are gone. The free tools (Connect Chrome extension, Weekly Visitor Report, TAM Calculator) were sunset on April 30, 2025. Logo API sunset follows on December 1, 2025. If you're not on HubSpot, Clearbit is not available to you.

What it does inside HubSpot, it does well. Breeze Intelligence enriches contact and company records with over 40 firmographic, demographic, and technographic attributes from a single email address or domain. It identifies companies visiting your website through IP intelligence. It shortens forms by hiding fields it can fill automatically, with customers like Gong reporting a 70% increase in demo requests and Mention improving signups by 54%. Because enrichment runs natively within HubSpot, data flows directly into lead scoring, workflows, and campaign segmentation without integration work.

ZoomInfo was founded in 2007 and has spent nearly two decades building a large B2B data platform. The scale is different: 500M contacts, 100M companies, 135M+ verified phone numbers, 120M direct-dial phone numbers, and 200M+ verified business email addresses. Data is verified through a multi-source pipeline backed by 300+ human researchers with up to 95% accuracy on first-party data. But the platform ambition is also different.

ZoomInfo does not just enrich existing records. It lets teams discover new contacts, monitor buyer intent across the web, record and analyze sales calls, orchestrate multi-channel campaigns, and access all of this through any front-end. The GTM Context Graph processes 1.5B+ data points daily by unifying ZoomInfo's third-party data with a customer's CRM records, conversation transcripts, and behavioral signals. The goal: capture not just that a deal moved to stage 3, but why it moved, so AI can recommend the right next action.

The contrast is structural. Clearbit enriches what you already have in HubSpot. ZoomInfo builds the intelligence infrastructure that powers prospecting, engagement, and deal execution across any CRM and any tool. Free to start with consumption credits based on usage, and a permanent free tier (ZoomInfo Lite with 10 monthly exports and no credit card required) removes the evaluation barrier.

Data enrichment: Native HubSpot vs. CRM-agnostic depth

Both platforms enrich CRM records. The approaches differ in coverage, depth, and flexibility.

Clearbit enriches contacts and companies from 100+ B2B attributes drawn from 250+ data sources. Person enrichment returns identity fields (name, location, timezone), professional details (title, normalized role, seniority), and social handles. Company enrichment returns firmographics (industry, employee count, revenue, founded year), technology stack detection, and corporate hierarchy fields (parent domain, ultimate parent domain). One notable feature: it provides 6-digit NAICS, 8-digit GICS, and 4-digit SIC codes simultaneously, which is uncommon among enrichment vendors.

Within HubSpot, enrichment runs in multiple modes: automatic enrichment for new records, continuous monthly refresh for existing records, manual enrichment, bulk enrichment, and workflow-triggered enrichment. Property overwrite behavior is configurable per field, so enrichment will not overwrite manually verified data. Importantly, basic enrichment and continuous refreshes do not consume HubSpot Credits, making them free for any paid HubSpot subscriber.

The critical limitation: Clearbit enriches records you already have. It is not a prospecting database. The legacy Clearbit Prospector, which offered a searchable database of 200 million contacts, no longer exists as a standalone product. You cannot search for contacts by title, industry, or company size and build a list of net-new leads.

ZoomInfo handles enrichment and more. The data layer spans 500M contacts and 100M companies, verified through a multi-source pipeline backed by 300+ human researchers with up to 95% accuracy on first-party data. Enrichment covers company attributes, technographics (tracking 30,000+ technologies across 200+ categories at 30M+ companies), org charts with verified direct dials and business emails, and department-level data for multi-threaded selling.

ZoomInfo's enrichment is also available through multi-vendor enrichment from approximately 60 vendors via a codeless interface in ZoomInfo Operations, so it is not locked to ZoomInfo's own data. The platform can pull the best available data from multiple sources and apply perimeter protection to block bad data at entry.

For teams evaluating data completeness post-implementation, ZoomInfo's verification architecture is the structural differentiator. Third-party tests have shown ZoomInfo returning verified contact information for over 90% of evaluated records compared to Clearbit's narrower dataset coverage.

CRM compatibility: HubSpot only vs. any CRM

This is the first gate in the evaluation. If your team does not use HubSpot as your primary CRM, Clearbit (Breeze Intelligence) is not available to you. That is not a product limitation to work around. It is the commercial structure of the product after the 2023 acquisition.

The standalone Clearbit APIs that allowed any tech stack to integrate enrichment data are gone. The free tools that developers used to evaluate Clearbit's data quality were sunset on April 30, 2025. The remaining commercial path for Clearbit data runs exclusively through HubSpot Sales Hub, Marketing Hub, or Service Hub, consumed as HubSpot Credits on paid tiers.

For a RevOps team managing a Salesforce environment, this is a non-starter. For a company running Microsoft Dynamics, the same. For teams planning a CRM migration, building around a HubSpot-only enrichment tool creates a dependency that disappears if the CRM choice changes.

ZoomInfo integrates natively with Salesforce, HubSpot, Microsoft Dynamics, and other CRMs. The GTM Workspace seller surface and GTM Studio orchestration layer connect to your existing stack regardless of which CRM you run. The ZoomInfo MCP and Enterprise API expose the same intelligence to AI agents and custom workflows in any front-end.

For RevOps and GTM engineering teams evaluating vendor consolidation, this is the consolidation argument: a single platform that works across your existing CRM investment, your outbound tools, your conversation intelligence, and your developer surfaces, rather than a point solution that only works inside one ecosystem.

Intent data and visitor intelligence

Both platforms provide intent signals, but at different depths and from different sources.

Clearbit (Breeze Intelligence) identifies anonymous website visitors using IP intelligence (company-level identification). It scores visiting companies against your ICP and triggers personalized outreach via HubSpot workflows. This is first-party intent: you see which companies are visiting your site, when, and which pages. For marketing teams running HubSpot campaigns, this first-party signal is actionable and directly wired into their existing workflow.

The scope of Clearbit's intent layer stops there. It does not provide third-party topic research signals (what topics prospects are researching across the broader web). It does not resolve person-level contact information from web visits outside of HubSpot records. It competes directly with ZoomInfo WebSights (ZoomInfo's website visitor identification product), but Clearbit Reveal operates on a smaller IP-to-organization dataset than WebSights' 210 million IP-to-org pairings.

ZoomInfo provides multi-source intent data built from 210M IP-to-organization pairings, third-party topic research signals from across the web, and behavioral signals unified through the GTM Context Graph. The intent layer is not limited to first-party website activity. It captures what your accounts are actively researching across thousands of external sites, gives you the timing signal before a competitor engages, and feeds that context into GTM Studio plays and GTM Workspace seller recommendations.

The practical difference: Clearbit tells you a company visited your pricing page. ZoomInfo tells you that company has been actively researching your category for three weeks, which contacts at that company match your ICP, and recommends the next action based on what has worked for similar deals. That context gap is what the GTM Context Graph is designed to close.

Platform scope: What ZoomInfo does beyond enrichment

ZoomInfo is described as an all-in-one AI GTM Platform for a reason. Enrichment is one layer of a platform that spans the full revenue workflow.

The GTM Context Graph is the intelligence layer that sits above the data. It processes 1.5B+ data points daily by unifying ZoomInfo's B2B data with your first-party CRM data, conversation intelligence from Chorus, and behavioral signals from the web. The result is a context layer that enables AI to reason about your accounts, not just describe them.

For sellers, GTM Workspace provides a purpose-built front-end with AI agents that research accounts, draft outreach, and surface recommended actions based on pipeline context. For marketers and RevOps, GTM Studio enables multi-channel plays, audience building, and campaign orchestration from the same intelligence layer. For developers and RevOps engineers, APIs and MCP expose ZoomInfo data to AI agents, custom workflows, and any front-end tool.

Clearbit (Breeze Intelligence) has no equivalent in any of these categories. There is no seller workspace. There is no conversation intelligence product. There is no multi-channel campaign orchestration layer. There is no standalone API access. The Breeze Intelligence surface is limited to enrichment, visitor identification, and form shortening inside HubSpot's native product suite.

For a RevOps team evaluating vendor consolidation, this is the operational question: can ZoomInfo replace multiple point solutions (separate enrichment, intent, conversation intelligence, and outbound sequencing platforms) under one platform? That is the consolidation case ZoomInfo makes, and it is the case Clearbit, by its architecture, cannot make.

When Clearbit (Breeze Intelligence) is the right choice

Clearbit (Breeze Intelligence) is genuinely the right choice in specific circumstances, and it is worth being direct about when those apply.

Choose Clearbit (Breeze Intelligence) if:

Your team is fully committed to HubSpot as your CRM and marketing automation platform, and you have no plans to move to Salesforce or Dynamics. The value of Breeze Intelligence is its native HubSpot integration. Data flows directly into your records, workflows, and lead scoring without any integration overhead or separate vendor relationship.

Your use case is enrichment-only. If what you need is cleaner CRM data, better form conversion rates, and website visitor identification within HubSpot, Breeze Intelligence delivers on all three. The form shortening capability is proven: Gong reported a 70% increase in demo requests, and Mention improved signups by 54% using Clearbit's form enrichment. These are real outcomes for the marketing workflows Clearbit was built for.

You are on HubSpot Starter+ and want enrichment at no extra credit cost. Basic enrichment and continuous monthly refreshes are included in paid HubSpot subscriptions without consuming HubSpot Credits. That is a compelling value proposition for SMB and mid-market marketing teams already in the HubSpot ecosystem.

Your budget is constrained and you do not need a standalone prospecting database, conversation intelligence, or multi-channel orchestration. Breeze Intelligence is not trying to be those things. It is a focused enrichment and intent layer, and within that scope it executes well.

For teams outside HubSpot, or teams that need prospecting, CI, or full GTM orchestration, the calculus is different.

When ZoomInfo is the right choice

Choose ZoomInfo if your evaluation touches any of the following:

You use Salesforce, Microsoft Dynamics, or any CRM other than HubSpot. ZoomInfo integrates with all of them. Clearbit does not.

You need a standalone prospecting database to discover net-new contacts. ZoomInfo's database of 500M contacts with advanced search and filters lets you build lists by title, industry, company size, technology stack, and buying signals. Clearbit has no equivalent capability.

You need multi-source intent data beyond website visitor identification. ZoomInfo's intent layer spans third-party topic research, behavioral signals, and 210M IP-to-organization pairings, unified through the GTM Context Graph. The timing intelligence this provides, knowing a prospect is actively in-market before they arrive on your site, is the signal most demand generation teams need to prioritize their outreach.

You want to reduce vendor count rather than add to it. ZoomInfo replaces what would otherwise be separate purchases for data enrichment, intent signals, conversation intelligence, outbound sequencing, and developer API access. Smartsheet, for example, used ZoomInfo's intent data and CRM enrichment to achieve an 84% MQL lift, 26% opportunity rate lift, and 59% win rate lift. The Hackett Group used ZoomInfo's CRM Enrichment and Workflow Tools to deliver a 15% increase in pipeline, 2,000 new accounts, and 15,000 new contacts without adding additional vendor relationships.

For enterprise RevOps teams, ZoomInfo also carries SOC 2 Type II, ISO 27001, and ISO 27701 certifications, plus TRUSTe GDPR/CCPA compliance verification. That security posture matters when you're consolidating enrichment, intent, and CI into a platform your engineering team has to operate and maintain.

ZoomInfo holds 133 No. 1 rankings on G2 across Sales Intelligence, Buyer Intent, Data Quality, and Lead-to-Account Matching, and is recognized as a Leader in the Forrester Wave for Intent Data Providers B2B (Q1 2025) and a Gartner Magic Quadrant Leader for ABM Platforms.

Your RevOps or GTM engineering team needs verified data + orchestration that is not tied to a single CRM. The Universal Access pillar of ZoomInfo's platform (GTM Workspace, GTM Studio, APIs and MCP) means the same intelligence layer is accessible in the seller's front-end, the marketer's campaign builder, and the engineer's API stack.
