Clearbit vs. ZoomInfo: Which B2B Data Platform Fits Your GTM Needs in 2026?

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

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.

ZoomInfo operates on a different scale. It's a GTM platform built on 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails. Beyond data, ZoomInfo provides intent signals, conversation intelligence through Chorus, seller tools in GTM Workspace, campaign orchestration in GTM Studio, and open APIs that plug into any system.

In short, here's what we recommend:

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 website visitor identification, it fits naturally, especially since basic enrichment is now 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 a 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 (an intelligence layer that processes 1.5B+ data points daily) unifies this data with your CRM records, conversation transcripts, and behavioral signals to show the full context of your accounts.

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 different needs. Clearbit is a data layer for HubSpot. ZoomInfo is a GTM platform for the entire revenue organization.

Clearbit vs. ZoomInfo at a glance

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. 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 differs: 500M contacts, 100M companies, 135M+ verified phone numbers, 120M direct-dial phone numbers, and 200M+ verified business email addresses. But the ambition differs, too.

ZoomInfo doesn't 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 (ZoomInfo's intelligence layer) 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.

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.

Source: Clearbit Data

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 won't overwrite manually verified data. Importantly, basic enrichment and continuous refreshes don't consume HubSpot Credits, making them free for any paid HubSpot subscriber.

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

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 roughly 60 vendors via a codeless interface in ZoomInfo Operations, so it isn't 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.

More importantly, ZoomInfo is also a prospecting tool. Teams can search across 300+ company attributes, filter by department, seniority, technology usage, intent signals, and more, then export directly to CRM or engagement platforms. That's a category of functionality Clearbit doesn't offer.

Intent data and buyer signals

Both platforms identify companies showing buying interest. The scope and methodology differ.

Clearbit's Buyer Intent uses IP intelligence to match anonymous website visitors to companies. When someone visits your site, the HubSpot tracking code captures company domain, online identifiers, timestamps, and URL paths.

Users configure up to 10 visitor intent criteria (such as visits to pricing pages or product pages) with minimum visit thresholds. The visitor dashboard shows companies sorted by page views, unique visitors, or last visit date with a 90-day lookback.

A complementary layer called Research Intent goes beyond first-party data, identifying companies researching relevant topics across the broader web, not just on your site. This is a newer capability (launched in public beta in Spring 2025) that tracks up to 20 topics per portal.

Source: Clearbit Research Intent

The intent signals work within HubSpot's ecosystem. Identified companies can be enrolled into HubSpot workflows for automated outreach, and CRM cards on company records show visit counts and top pages. However, there is no documented way to push intent data to advertising platforms or external data warehouses.

ZoomInfo approaches intent from multiple angles. ZoomInfo Intent tracks signals from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings sourced monthly. This captures not just who's visiting your site, but who's researching relevant topics across the broader web.

Guided Intent, exclusive to ZoomInfo, identifies topics historically correlated with deal success rather than requiring teams to pick keywords manually. Instead of guessing which topics matter, the system analyzes your closed-won deals and recommends the intent signals that actually predict the pipeline.

WebSights resolves anonymous website traffic to companies, similar to Clearbit's visitor identification, but adds Automatic Traffic Filtering that separates real company visitors from bot traffic. ZoomInfo Marketing takes this further with contact-level site visitor identification, identifying specific people, not just companies.

Source: ZoomInfo WebSights

The practical difference: Clearbit tells you which companies visited your site and which topics they're researching. ZoomInfo tells you that, plus what they're searching across the web, which topics correlate with your actual wins, and who at those companies you should contact, with verified phone numbers and emails attached.

Prospecting and contact discovery

This is where the platforms diverge most.

Clearbit does not offer a prospecting database. It enriches known contacts and companies. If a lead fills out your form, Clearbit fills in the gaps. If you need to find new contacts at target accounts, build outbound lists, or discover decision-makers you don't already know, Clearbit has no tool for that.

ZoomInfo is, at its core, a prospecting platform. The database includes 120M direct-dial phone numbers and 200M+ verified business email addresses, searchable by hundreds of filters. Teams can build targeted lists by job title, department, seniority, company size, technology stack, intent signals, and more, then export directly to CRM or sales engagement platforms.

The AI layer adds another dimension. GTM Workspace gives sellers a complete book-of-business view combining CRM data, ZoomInfo intelligence, conversation history, and market signals. The Action Feed surfaces in-market buyers with pre-drafted outreach, so reps act on signals rather than searching for leads manually. The AI Assistant generates one-click account briefs pulling CRM history, company news, and stakeholder context.

For teams running outbound, this distinction matters. Clearbit helps you understand the leads who come to you. ZoomInfo helps you find, prioritize, and engage the leads you go after.

Platform scope: What else each platform does

Clearbit focuses on three capabilities: data enrichment, buyer intent (website visitor identification plus research intent), and form shortening. These are useful but narrow. They improve data quality and inbound conversion within HubSpot, but they don't extend into outbound prospecting, conversation intelligence, multi-channel campaign execution, or sales automation.

ZoomInfo covers more ground:

Conversation Intelligence. Chorus records and analyzes customer calls, meetings, and emails. It extracts talk ratios, sentiment, objection patterns, and competitive mentions.

Source: ZoomInfo Chorus

Chorus also feeds the GTM Context Graph (ZoomInfo's intelligence layer), capturing the context behind deal movement: the reasons a champion went quiet, or what a competitor mentioned predicts about deal risk. This gives ZoomInfo a depth of understanding that data enrichment platforms lack.

Campaign Orchestration. GTM Studio lets marketers and RevOps teams describe audiences in natural language, build plays from pre-built templates (inbound acceleration, competitive displacement, champion tracking), and activate campaigns across email, calls, display ads, LinkedIn, Meta, and Connected TV. Expansion plays that used to take 3 weeks now launch in 30 minutes, without engineering support.

Multi-Channel Marketing. ZoomInfo Marketing includes a native Demand-Side Platform for deploying display ads based on 300+ company attributes, FormComplete for reducing form fields (similar to Clearbit's form shortening), and Account Fit Scoring that predicts which company attribute patterns convert. Smartsheet reported a 40%+ increase in form fills, 84% increase in MQLs, and 59% increase in win rate using these tools.

Website Chat. ZoomInfo Chat identifies anonymous visitors using ZoomInfo's company data and triggers tailored experiences based on company profile and intent signals. Unlike generic chat tools, it knows who's visiting before the visitor self-identifies.

Source: ZoomInfo Chat

Operations. ZoomInfo Operations automates data quality (deduplication, verification, perimeter protection), lead routing (round-robin, territory rules, lead-to-account matching), and predictive modeling. Momentive reduced speed-to-lead from 20 minutes to 60 seconds using it.

For teams that need enrichment alone, Clearbit's focused approach avoids complexity. For teams building a complete go-to-market engine, ZoomInfo's breadth replaces multiple point solutions.

CRM compatibility and integration

This is a binary decision point.

Clearbit is exclusively available inside the HubSpot platform. There is no Breeze Intelligence API, no integration path to Salesforce, Microsoft Dynamics, Pipedrive, or any other CRM. The legacy Clearbit served any tech stack through REST APIs and had native integrations with Salesforce, Marketo, Segment, and Zapier.

Source: Clearbit by Hubspot

Those paths ended with the HubSpot acquisition. For HubSpot users, the upside is simplicity: enrichment is embedded in the CRM with no setup required.

ZoomInfo integrates with the major CRMs and go-to-market tools. The ZoomInfo App Marketplace lists 120 partner integrations including Salesforce, HubSpot, Microsoft Dynamics 365, Snowflake, and sales engagement platforms like Outreach and Salesloft.

The Enterprise API provides programmatic access for any custom application or workflow. ZoomInfo's MCP server connects AI models directly to ZoomInfo data through natural language, currently supporting Claude and ChatGPT. Cloud Partners enables direct data ingestion into AWS, Google Cloud, Snowflake, and Databricks.

Source: ZoomInfo API

API access is included in all relevant ZoomInfo plans, not sold as a premium add-on. Teams building custom tools, internal agents, or data pipelines can access ZoomInfo intelligence without additional licensing.

If your CRM is HubSpot and you want native enrichment with no configuration, Clearbit delivers that. If you use any other CRM, or if you need programmatic access to data outside your CRM, ZoomInfo is the option.

Pricing models

Clearbit's pricing is embedded within HubSpot's subscription model. Basic company and contact enrichment is included in all Starter+ Core Seats at no extra credit cost. Advanced features (Buyer Intent, Smart Properties) consume HubSpot Credits, allocated monthly: 3,000 credits/month for Professional, 5,000 credits/month for Enterprise. Additional credits cost $10 per 1,000 credits. Credits expire monthly with no rollover.

Total cost depends on your HubSpot subscription. If you already pay for HubSpot Professional or Enterprise, basic enrichment is free. If you need advanced intent features at scale, the credit costs add up and vary by usage. There is no standalone Clearbit pricing anymore.

ZoomInfo uses a custom-quoted, seat-and-credit-based subscription model with no publicly listed prices. Costs depend on the number of seats, monthly credit volume, features, and contract length.

The platform is organized into Sales, Marketing, and Operations product lines, each with Professional, Advanced, and Enterprise tiers. Credits are consumed when exporting data (1 credit = 1 export); searching and viewing data within ZoomInfo does not consume credits.

ZoomInfo offers two free entry points: ZoomInfo Lite, a permanent free tier with 10 monthly export credits and access to the B2B database, and a 7-day free trial of the full platform. Neither requires a credit card.

The pricing comparison isn't apples-to-apples. Clearbit's cost is bundled into HubSpot, making it cheap for existing HubSpot customers who need enrichment. ZoomInfo is a separate investment, but it covers prospecting, intent, conversation intelligence, campaign orchestration, and data operations that would otherwise require multiple tools.

Data quality and accuracy

Clearbit processes data through LLMs that extract, normalize, and categorize information from unstructured web content, with human reviewers checking for consistency and accuracy. Records are automatically refreshed when a change is detected, and continuous enrichment updates existing records monthly.

However, HubSpot does not publish match rates, accuracy percentages, or coverage by geography or industry for Breeze Intelligence, making it hard to benchmark against other providers.

ZoomInfo publishes more about its verification methodology. Data flows through automated ML scanning of 28 million site domains daily, third-party partner data covering 95 million businesses, a community of 200,000+ ZoomInfo Lite users who share business contact data back, and an in-house Data Training Lab of 300+ human researchers. First-party data reaches up to 95% accuracy.

External validation supports ZoomInfo's claims. In a Fortune 500 competitive RFP analyzing 25 million contacts across vendors, the independent consultant concluded that "no other competitor came even close." ZoomInfo was named a Leader in Forrester's Wave for Intent Data Providers B2B in Q1 2025, receiving the highest possible scores across eight criteria. On G2, ZoomInfo holds 133 No. 1 rankings across Sales Intelligence, Buyer Intent, Data Quality, and related categories.

Both platforms take data quality seriously, but ZoomInfo provides more transparency about accuracy and has stronger third-party validation.

Security and compliance

Clearbit maintains SOC 2 Type 2 certification, GDPR alignment using legitimate interest as the legal basis for B2B professional data, and CCPA compliance as a registered data broker in California. Infrastructure runs on Amazon Web Services and Google Cloud Platform with TLS v1.2/v1.3 in transit and AES-256 at rest. A Privacy Request Form handles data access, correction, or erasure. Clearbit also inherits HubSpot's broader security infrastructure and Trust Center.

ZoomInfo holds a broader certification stack, all renewed annually: ISO 27001 (information security management), SOC 2 Type II, ISO 27701 (privacy information management), and TRUSTe validations for GDPR and CCPA. ZoomInfo is a registered data broker in California and Vermont, with a dedicated Trust Center.

Both platforms meet high compliance standards. ZoomInfo's additional ISO certifications and TRUSTe validations reflect the requirements of its enterprise customer base, which includes regulated institutions in financial services and healthcare.

Clearbit vs. ZoomInfo: Which should you choose?

The choice depends on what your team needs and which CRM you use.

Choose Clearbit (Breeze Intelligence) if:

• You're already on HubSpot and want native enrichment with no integration work

• Your primary need is filling in missing company data on inbound leads

• You want to identify which companies visit your website and route them into HubSpot workflows

• Form shortening to improve conversion rates is a priority

• You don't need a prospecting database for outbound list building

• You want enrichment included in your existing HubSpot subscription without a separate vendor

Clearbit's strength is its tight integration with HubSpot. For teams that live in HubSpot and primarily run inbound, it provides the enrichment and visitor identification they need without adding another vendor or login. The HubSpot acquisition made this integration tighter still, with basic enrichment now included at no extra cost.

ZoomInfo serves a different scope. It's built on three layers: a large B2B data foundation, the GTM Context Graph intelligence layer that fuses that data with your first-party signals to reveal why deals move or stall, and access through GTM Workspace for sellers, GTM Studio for marketers and RevOps, and APIs and MCP for any tool. That architecture powers the entire go-to-market motion, not just one piece of it.

The question isn't which platform has better data enrichment. It's whether you need data enrichment alone, or a complete go-to-market intelligence platform. Answer that, and the choice is clear.
