Clearbit vs HubSpot

If you are comparing Clearbit vs. HubSpot, the first thing to know is that they are the same company now. HubSpot acquired Clearbit in December 2023 and rebranded its capabilities as Breeze Intelligence at INBOUND 2024. The real question is not which one to pick. The real question is whether HubSpot's built-in data enrichment layer gives your GTM team enough intelligence to work with, or whether you need a standalone intelligence platform that works across your entire stack.

Here are the questions that actually drive the decision:

• Do you need to enrich records you already have, or do you need a database to find buyers you do not have yet?

• Is your CRM HubSpot exclusively, or do you run Salesforce, Dynamics, or a custom environment that also needs clean, enriched data?

• Do you need enrichment that works inside one platform, or intent signals that fire across your full go-to-market motion?

• Is the goal filling in CRM fields, or understanding which accounts are in-market, who to contact, and what to say?

• Do your marketing and RevOps teams need to build audiences from scratch, or do they work exclusively from your existing database?

In short, here is what each option delivers:

Clearbit (now HubSpot Breeze Intelligence) enriches contact and company records inside HubSpot with 40+ firmographic, demographic, and technographic attributes drawn from 200M+ company and buyer profiles. It identifies anonymous website visitors, shortens forms to improve conversion rates, and refreshes CRM data automatically. For HubSpot customers, it is a convenient, built-in data layer. It is exclusively available inside HubSpot, has no prospecting database, and no longer offers the CRM-agnostic APIs that made the original Clearbit popular with product-led growth and RevOps teams.

HubSpot is an all-in-one customer platform spanning Marketing Hub, Sales Hub, Service Hub, Content Hub, Data Hub, and Commerce Hub, with Breeze AI embedded across all Hubs. Its Breeze Prospecting Agent surfaces in-market accounts and builds personalized outreach sequences, though the underlying contact data powering it is provided by Apollo, not HubSpot's own database. HubSpot is a strong choice for teams that want CRM, automation, and enrichment under a single subscription. But it is a CRM platform with enrichment added, not a standalone intelligence platform.

ZoomInfo is an all-in-one AI GTM Platform built on the largest verified B2B data foundation: 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails. Its GTM Context Graph, which processes 1.5B+ data points daily, fuses this data with your CRM records, conversation intelligence from Chorus, and behavioral signals to reveal not just what happened, but why and what to do next. That intelligence is available through GTM Workspace for sellers, GTM Studio for marketers and RevOps, or via APIs and ZoomInfo MCP in any front-end or AI agent.

Clearbit vs. HubSpot vs. ZoomInfo at a Glance

Clearbit and HubSpot Are Now the Same Product

This is the most important context for anyone searching "Clearbit vs. HubSpot" in 2026. Clearbit no longer exists as a standalone product.

Here is the timeline:

• November 2023: HubSpot signed the acquisition agreement

• December 2023: HubSpot completed the acquisition

• September 2024: Clearbit's capabilities were rebranded as Breeze Intelligence under HubSpot's Breeze AI platform

• April 2025: All standalone Clearbit free tools were sunset -- the Connect Chrome extension, Weekly Visitor Report, TAM Calculator, and free platform

• December 2025: The Clearbit Logo API sunset date

What this means in practice:

If you are a HubSpot customer, Clearbit's enrichment is now built into your CRM. Basic company and contact enrichment no longer consumes credits and is included in all Starter Core Seats. You get automatic enrichment of new records, monthly refreshes, and form shortening at no extra cost. Advanced features like Buyer Intent and Smart Properties still consume HubSpot Credits, which reset monthly with no rollover.

If you are not a HubSpot customer, Clearbit is no longer available to you. Breeze Intelligence is exclusively available inside the HubSpot platform. There is no Breeze Intelligence API, no integration path to Salesforce, Dynamics, or any other CRM. The API-based enrichment platform that made Clearbit popular with RevOps and developer teams no longer exists as a standalone option.

This merger is the defining fact of this comparison: choosing Clearbit now means choosing HubSpot.

What HubSpot Breeze Intelligence (Clearbit) Actually Does

HubSpot Breeze Intelligence is the post-acquisition product surface -- Clearbit's data and logic inside HubSpot's Smart CRM. It covers four main capabilities:

Data enrichment: Breeze Intelligence enriches contact and company records with 40+ firmographic, demographic, and technographic attributes -- company name, industry (with NAICS, GICS, and SIC codes), employee count, revenue, technology stack, and job seniority. Enrichment happens automatically for new records, refreshes monthly for existing records, and can be triggered manually or through workflows.

Website visitor identification: Breeze Intelligence identifies anonymous website visitors by company using IP intelligence and alerts marketing and sales teams to high-intent visitors. This capability competes directly with ZoomInfo WebSights, though Clearbit's IP-to-organization dataset is smaller than ZoomInfo's 210M IP-to-org pairings.

Form shortening: Dynamic form shortening reduces friction on landing pages by pre-filling fields Breeze can enrich from an email address. Chili Piper, using ZoomInfo's equivalent FormComplete product, reduced their form from seven fields to three and saw a 26% increase in conversions -- illustrating what this category delivers when the underlying data is deep enough.

Buyer intent: Breeze Intelligence includes a buyer intent signal that identifies companies researching relevant topics. This is a HubSpot Credits-based feature available in Professional and Enterprise editions.

Known limitations of Breeze Intelligence:

• Exclusively available inside HubSpot -- no API, no non-HubSpot CRM path

• Dataset size: 200M company and buyer profiles vs. ZoomInfo's 500M contacts

• No prospecting database -- enriches records you already have, does not surface net-new buyers

• Standalone Clearbit free tools (Connect, Weekly Visitor Report, TAM Calculator) fully sunset

• Original Clearbit API-based enrichment path no longer available for developer and RevOps use cases

What HubSpot as a Platform Actually Does

HubSpot is a customer platform -- a substantially broader software footprint than either Clearbit alone or ZoomInfo. Its Hubs cover the full customer lifecycle:

Sales Hub: CRM-native seller workflows -- deal management, email sequences, meeting scheduling, and AI Prospecting Agent. The Breeze Prospecting Agent identifies in-market accounts and builds personalized outreach, but the underlying contact data is provided by Apollo, not HubSpot's own database. Pricing: Starter $9/seat/month, Professional $90/seat/month, Enterprise $150/seat/month (annual billing); required onboarding fees of $1,500 (Professional) and $3,500 (Enterprise).

Marketing Hub: AI-powered marketing automation spanning campaigns, landing pages, email, ads, ABM features, and attribution. The most-used SMB and mid-market marketing platform, with strong CRM-native integration. HubSpot is a direct competitor to ZoomInfo Marketing at the marketing automation layer, though HubSpot's ABM motion is generally less data-intensive than ZoomInfo Marketing's Gartner Magic Quadrant Leader positioning.

Breeze AI agents: Six specialized AI agents running across HubSpot -- Customer Agent, Prospecting Agent, Data Agent, Customer Health Agent, Company Research Agent, and Closing Agent. These agents run inside HubSpot CRM context: they reason over your HubSpot data. They do not reason across external signals, cross-system behavioral data, or conversation intelligence the way ZoomInfo's GTM Context Graph does.

HubSpot's structural gap: HubSpot does not maintain a proprietary B2B contact database. It relies on partners -- notably Apollo for Breeze Prospecting, and Breeze Intelligence (Clearbit data) for enrichment. This means HubSpot customers who need new-buyer discovery are dependent on Apollo's data quality, coverage, and commercial terms for prospecting.

Known limitations of HubSpot for B2B intelligence:

• No proprietary B2B contact or company database

• Breeze Prospecting Agent contact data is Apollo-sourced, not native

• Conversation intelligence requires partner integration (no native CI product)

• Breeze AI agents reason inside HubSpot data only -- no cross-signal reasoning layer

• HubSpot-specific enrichment: only works if HubSpot is your CRM of record

The Gap Both Tools Share

Both Clearbit (Breeze Intelligence) and HubSpot solve one problem well: enriching CRM records you already have.

Clearbit enriches your existing HubSpot contacts. HubSpot enriches your existing HubSpot pipeline with Breeze data. The Breeze Prospecting Agent finds accounts that match your ICP and builds outreach -- but the data powering it is Apollo's, not a native HubSpot or Clearbit asset.

Neither tool answers these questions reliably:

• Which accounts outside my CRM are in-market right now?

• Which companies are researching my category across the open web -- not just my own website?

• How do I enrich, prospect, and activate if my team runs Salesforce, not HubSpot?

• What does my conversation history with accounts tell me about their intent and next best action?

• How do I build an audience in my MAP, sync it to my CRM, and execute ads, outreach, and content with the same underlying data?

These are the questions a standalone intelligence platform is built to answer.

ZoomInfo: Standalone Intelligence Across Your Entire GTM Motion

ZoomInfo is an all-in-one AI GTM Platform -- not a CRM add-on, not an enrichment layer for one vendor's ecosystem. It is the data and intelligence foundation that connects to your entire tech stack.

Data foundation: ZoomInfo's B2B data platform covers 500M contacts, 100M companies, 135M+ verified phone numbers, 120M direct-dial phone numbers, and 200M+ verified business email addresses. Multi-source verification with 300+ human researchers delivers up to 95% accuracy on first-party data. Unlike Clearbit's 200M-profile dataset, ZoomInfo's data includes a full prospecting database -- not just enrichment of known records.

GTM Context Graph: The GTM Context Graph is ZoomInfo's intelligence layer, processing 1.5B+ data points daily. It fuses ZoomInfo's B2B data with your CRM records, conversation transcripts from Chorus, and behavioral signals to surface patterns your team cannot see from any single source. This is the layer that enables AI to recommend the next best action grounded in what actually drives your closed-won deals -- not just what the prospect's LinkedIn says. ZoomInfo was named a Leader in the Forrester Wave for Intent Data Providers, Q1 2025, receiving the highest possible scores across eight criteria.

Universal Access: ZoomInfo works in any tool, any workflow, and any AI agent. Three access lanes cover every use case: GTM Workspace puts ZoomInfo intelligence in front of sellers; GTM Studio gives marketers and RevOps teams the audience-building and orchestration layer; APIs and ZoomInfo MCP connect ZoomInfo data to any custom tool or AI agent. This is the structural difference from Breeze Intelligence -- ZoomInfo is not bound to any single CRM. It enriches Salesforce, HubSpot, Dynamics, and 120+ other systems through the same data foundation.

In practice: Redwood Logistics used ZoomInfo Marketing's data-powered ad targeting to achieve a 99% reduction in cost per click and a 310% increase in CTR, while saving 25 hours per week in operational overhead. This is the kind of outcome the enrichment-only path does not produce -- because it requires not just clean CRM records, but the right audience signal at the right time, activated across multiple channels.

Data Enrichment: Embedded Convenience vs. Verified Depth

Both Clearbit/Breeze Intelligence and ZoomInfo enrich CRM records with company and contact data. The mechanics, depth, and portability differ.

Breeze Intelligence enriches with 40+ attributes from a single email address or domain. Enrichment is automatic for new HubSpot records and refreshes monthly. Basic enrichment is now included in HubSpot Starter Core Seats with no credit cost. For form shortening, visitor ID, and buyer intent, HubSpot Credits apply. No configuration is needed for HubSpot users -- it is genuinely low-friction.

ZoomInfo CRM Enrichment enriches with 300+ verified attributes per record -- company, contact, technographic, firmographic, and intent signals. It supports Salesforce, HubSpot, Dynamics, and 120+ systems through native integrations, not Zapier. Enrichment runs on a configurable schedule with deduplication and routing logic built in via ZoomInfo Operations. For teams outside HubSpot, ZoomInfo CRM Enrichment is the primary path for keeping their data clean and complete.

The practical trade-off: Breeze Intelligence is more convenient for HubSpot-native teams who do not need to configure anything. ZoomInfo CRM Enrichment delivers more depth, broader CRM compatibility, and a prospecting layer that Breeze does not offer. For teams running Salesforce or a mixed stack, Breeze Intelligence is simply not available -- ZoomInfo is the default path.

Intent Data: Website Visitors vs. In-Market Intelligence

Intent data is where the structural gap between these tools becomes most visible.

Clearbit/Breeze Intelligence identifies anonymous website visitors at the company level using IP intelligence. You see which companies visited your site, how often, and which pages they viewed. This is warm inbound signal -- valuable for following up with companies already engaging your content. It is company-level, website-specific, and limited to activity on your own site.

HubSpot Breeze Prospecting Agent uses intent data to surface in-market accounts for outbound sequences. The underlying signal source is Apollo's data, not a proprietary HubSpot signal network. The intent surface is scoped to HubSpot's CRM context.

ZoomInfo Intent operates at a fundamentally different scale. ZoomInfo tracks 210 million IP-to-org pairings and over 6 trillion keyword-to-device pairings monthly across ZoomInfo's own signal network -- not a third-party cooperative like Bombora. Guided Intent identifies the accounts most likely to convert based on your own historical win patterns, not just generic topic spikes. ZoomInfo was named a Leader in the Forrester Wave for Intent Data Providers, Q1 2025, with the highest possible scores across eight evaluation criteria.

For demand generation and marketing ops teams evaluating intent tools, source transparency matters: an intent signal is only as valuable as the network generating it. ZoomInfo's proprietary signal network, Guided Intent modeling, and Forrester Wave Leader status provide the kind of analyst-validated evidence that survives a CMO's scrutiny.

AI Agents: CRM-Bound Reasoning vs. Cross-Signal Intelligence

HubSpot's Breeze AI and ZoomInfo's GTM Context Graph both pitch AI agents that help GTM teams work faster. The difference is what each agent can reason over.

HubSpot Breeze agents operate inside HubSpot's CRM context. The Data Agent answers questions about your HubSpot contacts, deals, and activity history. The Prospecting Agent builds outreach sequences for in-market accounts, using Apollo contact data. The Customer Agent handles support conversations. All of these agents are useful for teams already living in HubSpot -- but their intelligence is bounded by what is in your HubSpot instance. They do not reason across conversation transcripts from external calls, third-party behavioral signals, or verified contact attributes that are not already in HubSpot.

ZoomInfo GTM Context Graph operates at a different scope. The Context Graph fuses ZoomInfo's B2B data with your CRM records, conversation intelligence from Chorus, and behavioral signals into a single reasoning layer. This means an AI agent working with ZoomInfo data can recommend the right account to prioritize not just because they visited your website, but because they match your historical win pattern, are researching your category across the open web, and your account executive had a conversation with a buyer at that company six months ago. That level of signal fusion is what the Context Graph is built for -- and it is not replicated by a CRM-bound reasoning layer.

For RevOps and GTM engineers evaluating this dimension: HubSpot Breeze agents require HubSpot as the data source. ZoomInfo's APIs and ZoomInfo MCP let you connect ZoomInfo intelligence to custom agents, Claude, and any AI front-end -- so the intelligence layer is not locked to a single CRM or workflow surface.

HubSpot and ZoomInfo as Partners, Not Just Competitors

One nuance worth naming: many enterprise and mid-market teams run both HubSpot and ZoomInfo simultaneously. HubSpot is the CRM of record and marketing automation platform. ZoomInfo is the data and intelligence layer that enriches it.

This is not an either/or decision for a significant share of the market. Apollo is the data provider for HubSpot's Breeze Prospecting Agent -- and ZoomInfo is available as a paid integration on HubSpot's App Marketplace. The "HubSpot vs. ZoomInfo" framing is most relevant for teams deciding which platform owns the intelligence function, not necessarily which platform owns the workflow.

The practical question is: where does your team need intelligence that goes beyond what your CRM already holds? For enrichment of existing records inside HubSpot, Breeze Intelligence is convenient and included. For prospecting new buyers, running Salesforce, activating intent signals, or building audiences across your full marketing and sales stack -- that is where ZoomInfo's standalone data and intelligence platform earns its place.

When to Choose Each Tool

Choose Clearbit (HubSpot Breeze Intelligence) if:

• Your team is fully committed to HubSpot as your CRM of record and wants no additional vendor to manage

• Your primary need is CRM data enrichment and you do not need a prospecting database

• Your team benefits from Clearbit's form-shortening and visitor-ID capabilities inside HubSpot workflows

Frequently Asked Questions

Is Clearbit still a standalone product in 2026?

No. HubSpot acquired Clearbit in December 2023 and rebranded its capabilities as Breeze Intelligence at INBOUND 2024. All standalone Clearbit free tools, including the Connect Chrome extension, Weekly Visitor Report, TAM Calculator, and free platform, were sunset in April 2025. Breeze Intelligence is now exclusively available inside HubSpot. Teams not using HubSpot no longer have a Clearbit path.

Does HubSpot have a B2B prospecting database?

Not a proprietary one. HubSpot's Breeze Prospecting Agent identifies in-market accounts and builds personalized outreach, but the underlying contact data is provided by Apollo -- not a HubSpot-owned database. Breeze Intelligence enriches records you already have. It does not provide a prospecting database for finding net-new buyers outside your CRM.

Can ZoomInfo work with HubSpot?

Yes. ZoomInfo integrates natively with HubSpot through the ZoomInfo App on HubSpot's App Marketplace. ZoomInfo enriches HubSpot contact and company records, syncs intent signals, and supports bidirectional data flows -- without replacing HubSpot as your CRM of record. Many go-to-market teams run HubSpot as the CRM and ZoomInfo as the data and intelligence layer underneath it.

What is the best alternative to Clearbit for teams not using HubSpot?

ZoomInfo is the most direct alternative for non-HubSpot teams. It integrates natively with Salesforce, Dynamics, Outreach, Salesloft, and 120+ systems. Unlike Breeze Intelligence, ZoomInfo works regardless of which CRM you use, adds a full prospecting database, and provides intent data from ZoomInfo's own signal network rather than a third-party cooperative.

How does ZoomInfo's intent data compare to Clearbit's buyer intent?

Clearbit's Breeze Intelligence identifies anonymous website visitors at the company level -- a useful signal for warm inbound follow-up. ZoomInfo Intent tracks 210 million IP-to-org pairings and over 6 trillion keyword-to-device signals monthly across ZoomInfo's own network. Guided Intent identifies accounts most likely to convert based on your historical win patterns. ZoomInfo was named a Leader in the Forrester Wave for Intent Data Providers, Q1 2025.

Is ZoomInfo better than HubSpot for demand generation?

They serve different roles in a demand gen stack. HubSpot is a marketing automation platform -- it runs campaigns, nurtures leads, and manages the CRM. ZoomInfo is the data and intelligence layer: it provides the audience data, intent signals, and enrichment that powers campaigns across any MAP or CRM. Redwood Logistics used ZoomInfo Marketing's data-powered ad targeting to achieve a 99% reduction in cost per click and a 310% increase in CTR while saving 25 hours per week in operational overhead. Many high-growth demand gen teams run HubSpot for campaign execution and ZoomInfo for data and intent.
