Clearbit vs. LeadIQ (vs. ZoomInfo): Which B2B Data Platform Fits Your Go-to-Market Needs in 2026?

Choosing between Clearbit and LeadIQ for your B2B data needs often comes down to five questions:

• Do you need data enrichment inside your CRM, or a prospecting tool that helps reps find and reach new contacts?

• Is your team built around HubSpot, Salesforce, or a mix of both?

• Do you need intent signals to spot in-market buyers, or champion tracking to catch job changes?

• Are you looking for a tool that handles one piece of your workflow well, or a platform that covers prospecting, enrichment, intent, and outreach in one place?

• How important is it to access your B2B data through APIs, AI agents, and custom workflows, not just a single UI?

In short, here's what we recommend:

Clearbit (now Breeze Intelligence by HubSpot) is the right choice for HubSpot customers who need automatic data enrichment, form shortening, and buyer intent built into their CRM. Acquired by HubSpot in December 2023, Clearbit enriches contact and company records with over 40 firmographic, demographic, and technographic attributes without API setup. Basic enrichment is now included at no extra cost for all HubSpot Starter+ seats. However, Clearbit lives exclusively inside HubSpot. It offers no standalone API, no prospecting database, and no outbound contact discovery.

LeadIQ is built for SDR and BDR teams who prospect from LinkedIn and need verified contact data pushed into their CRM in one click. Its Chrome extension is used by 30,000 sellers, and the platform bundles champion tracking, CRM enrichment, and an AI email writer called Scribe. LeadIQ's 749M+ contact database with strong EMEA coverage fits global outbound teams well. But LeadIQ has no intent data, no website visitor identification, and no native outreach execution. You'll still need Outreach, Salesloft, or Gong to send sequences.

Both platforms solve real problems. Clearbit keeps your HubSpot CRM clean. LeadIQ helps reps find prospects faster. But neither covers the full go-to-market motion: finding buyers, understanding their intent, engaging across channels, and keeping data accurate across every system. That's where a single platform changes the equation.

ZoomInfo is an AI-powered GTM platform built on a large data foundation: 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business email addresses. Its GTM Context Graph, which processes 1.5B+ data points daily, unifies this data with your CRM records, conversation transcripts, and behavioral signals to reveal the full context of your accounts. That context gives AI the fuel to show not just what happened, but why it happened, and what to do next. With that intelligence, your team can run sales motions from the GTM Workspace for sellers, build GTM plays from GTM Studio for marketers and RevOps, or power their own tools through the API and MCP in any front-end.

Clearbit vs. LeadIQ vs. ZoomInfo at a glance

They solve different problems for different teams

The most important distinction between these three platforms isn't features. It's what job each one was built to do.

Clearbit is a data enrichment layer for HubSpot. It takes incomplete CRM records (an email address, a company domain) and fills in the blanks: industry, employee count, revenue, seniority, tech stack. It also identifies which companies visit your website and shortens web forms so more leads convert. Everything happens inside HubSpot, automatically.

If your team runs on HubSpot and your main frustration is incomplete records and low form conversion, Clearbit delivers without requiring new tools or workflows.

LeadIQ is a prospecting tool for outbound sales reps. It sits alongside LinkedIn as a Chrome extension, surfaces verified emails and phone numbers, and pushes contacts into Salesforce or a sales engagement platform in one click.

If your SDR team lives in LinkedIn Sales Navigator and needs to build lists faster with accurate contact data, LeadIQ removes the manual work.

ZoomInfo is a full go-to-market platform. It starts with the same enrichment and prospecting capabilities but extends into intent signals, conversation intelligence, website visitor identification, marketing orchestration, and AI-powered outreach.

ZoomInfo exists because most B2B teams don't just need data in one place. They need it everywhere: in the CRM, in the sequencer, in the ad platform, in the AI agent, in the meeting prep brief.

This isn't a knock on Clearbit or LeadIQ. They're good at what they do. But the scope of what they do is narrower, and understanding that scope is the key to choosing correctly.

Data scale: ZoomInfo's foundational advantage

Clearbit's dataset spans 200M+ company and buyer profiles drawn from 250+ data sources.

It excels at firmographic enrichment: 100+ B2B attributes including simultaneous 6-digit NAICS, 8-digit GICS, and 4-digit SIC codes, corporate hierarchy fields, and normalized role and seniority data. What Clearbit doesn't offer is a searchable database of individual contacts for outbound prospecting.

You can enrich a lead who submits a form, but you can't discover a VP of Engineering at a target account who hasn't engaged with you yet.

LeadIQ's database of 749M+ contacts with 60%+ refreshed in the last six months covers more ground for prospecting.

The platform uses real-time verification on every search rather than batch refreshes, and its 49M mobile phone numbers give reps direct lines. LeadIQ's international coverage is strong, with G2 Leader badges across Americas, EMEA, Europe, UK, and India.

ZoomInfo operates at a larger scale: 500M contacts, 100M companies, 135M+ verified phone numbers, 120M direct-dial phone numbers, and 200M+ verified business email addresses.

The verification pipeline combines 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 data back, and 300+ human researchers. First-party data reaches up to 95% accuracy.

The gap isn't just numbers. In a Fortune 500 competitive RFP analyzing 25 million contacts across vendors, the independent consultant concluded that "no other competitor came even close." That kind of external validation matters when your pipeline depends on data accuracy.

CRM enrichment: Clearbit's home turf, with caveats

Clearbit's enrichment inside HubSpot is well-integrated. Since the December 2023 acquisition, the product (rebranded as Breeze Intelligence at INBOUND 2024) has been embedded into HubSpot's Smart CRM. No API configuration.

No middleware. Enrichment works through multiple modes: automatic (new records enriched instantly), continuous (existing records refreshed monthly at no credit cost), manual, bulk, and workflow-triggered. Property overwrite behavior is configurable per field, so enrichment won't clobber manually verified data.

Source: HubSpot

The caveat is lock-in. Breeze Intelligence is exclusively available inside HubSpot. If your CRM is Salesforce, Dynamics, Pipedrive, or anything else, Clearbit can't help you. The standalone API that originally served any CRM is no longer available, and all legacy free tools were sunset on April 30, 2025.

LeadIQ's enrichment product, called Refresh, works across both CRMs.

Source: LeadIQ

For Salesforce, it delivers a native Managed Package that installs into the org. Enrichment triggers on record creation, update, or scheduled cadence. Rockset reported that records were matched and enriched within two minutes of a lead arriving, with a 90% match rate on personal emails and 54% more inbound leads routed correctly.

For HubSpot, the integration runs through a Workato recipe, which works but isn't as tightly integrated as Clearbit's native HubSpot embedding.

ZoomInfo's enrichment spans all three major CRMs (Salesforce, HubSpot, and Microsoft Dynamics) and goes further through multi-vendor enrichment from roughly 60 vendors via a codeless interface in ZoomInfo Operations.

The GTM Studio waterfall enrichment evaluates 25+ data sources and returns the highest-confidence result, included at no additional cost.

For teams that need enrichment across multiple systems (or need to pipe data into warehouses, ad platforms, and custom workflows), ZoomInfo's Enterprise API and MCP access deliver the same data anywhere.

Prospecting: LeadIQ's strength, Clearbit's blind spot

Clearbit has no prospecting database. The legacy Clearbit Prospector that provided a searchable contact database was absorbed into HubSpot and is not available as a standalone capability. Breeze Intelligence enriches the records you already have. It does not help you find new ones.

This is LeadIQ's core territory.

The Chrome extension sits alongside LinkedIn Sales Navigator and surfaces verified emails, mobile numbers, and firmographic data in a side panel. Reps add contacts to lists in one click, push them to Salesforce or HubSpot, and enroll them in Outreach or Salesloft sequences without leaving the browser.

Greenhouse's SDR team adopted LeadIQ as its pipeline generation platform after a trial where 90% of reps endorsed it. WalkMe's BDR team saved 1,000 hours per quarter by eliminating manual contact research.

LeadIQ's Scribe AI adds another layer: it generates personalized cold emails using prospect data, company signals, and value propositions in five languages, and it's included free with Prospecting Hub.

Source: LeadIQ

ZoomInfo's prospecting covers the same ground through Contact & Company Search with 300+ attributes, department org charts, and job-change alerts, but adds dimensions LeadIQ doesn't offer.

Buyer Intent data identifies which target accounts are researching relevant topics, so reps find contacts at accounts that are ready to buy, not just contacts.

GTM Workspace takes this further with an AI-powered Action Feed that surfaces in-market buyers matched to your criteria, complete with pre-drafted outreach. Seismic attributed 39% of active pipelines to opportunities identified by ZoomInfo signals.

Intent signals: where the approaches diverge

Clearbit's Buyer Intent uses IP intelligence to identify companies visiting your website, filtered by ICP criteria.

Source: Clearbit

You define target markets by industry, location, and employee count, then track which matching companies visit specific pages (pricing, product, case studies). It supports up to 10 visitor intent criteria with a 90-day lookback.

A newer layer called Research Intent extends this to find companies researching relevant topics across the broader web. The signals are useful, but they live inside /HubSpot and can't be exported to ad platforms or external systems.

LeadIQ does not offer intent data. The platform covers intent data providers as a separate tool category in its blog content, acknowledging the gap. Teams needing intent signals alongside LeadIQ must buy a separate provider (Bombora, G2, or others) and stitch the data together.

ZoomInfo's intent engine operates at a different scale. ZoomInfo Intent tracks signals from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings sourced monthly.

The key differentiator is Guided Intent, which identifies topics historically correlated with deal success in your pipeline rather than requiring you to guess which topics matter.

Forrester named ZoomInfo a Leader in Intent Data Providers for B2B (Q1 2025), giving it the highest possible scores across eight criteria.

WebSights adds contact-level website visitor identification (who visited, not just which company), with Automatic Traffic Filtering that separates real visitors from bots.

The combination of third-party intent, first-party website visitor data, and verified contact information in one platform means sales and marketing teams can act on signals immediately, without stitching data across vendors.

Champion tracking and job-change signals

Clearbit doesn't track job changes. If a champion leaves a customer account or a past buyer starts at a new company, Breeze Intelligence won't flag it.

LeadIQ's Champion Tracking monitors past buyers, power users, and decision-makers for job changes, then delivers alerts with verified new contact data (email, phone, LinkedIn URL, title, company).

Source: LeadIQ

The feature is Salesforce-native, so workflows handle old record management, new record creation, and owner notifications inside the CRM. Workato booked 10-15 meetings in two months from job change signals alone, with open rates of 60-70% (compared to a 30-40% industry benchmark).

LeadIQ positions this as superior to standalone tools like UserGems and Champify because the alerts include verified new contact data, not just a notification that requires separate enrichment.

ZoomInfo includes champion tracking through its Contact Tracker feature, and within GTM Studio plays.

Job-change alerts come enriched with ZoomInfo's full contact and company data and can trigger automated outreach workflows.

The difference: ZoomInfo's champion tracking sits alongside intent signals, conversation intelligence, and the broader intelligence layer, so a job-change alert is one signal among many feeding a complete account picture rather than a standalone notification.

Form shortening: a Clearbit specialty

One area where Clearbit stands out is form optimization.

Form shortening removes fields that Clearbit can auto-fill from an email address alone. The visitor sees a single email field; if Clearbit has enrichment data, the remaining fields are hidden and auto-populated. If not, the visitor fills out all fields. The result is 100% data coverage without forcing every visitor through a long form.

Source: HubSpot

The conversion impact is measurable. Gong increased demo requests by 70%. Mention improved signups by 54%. As of September 2025, form shortening no longer consumes HubSpot Credits, making it free for all HubSpot users.

LeadIQ offers webform enrichment but not form shortening. The platform enriches submitted form data after the fact rather than reducing the number of fields displayed.

ZoomInfo's equivalent is FormComplete, which reduces forms to a single field and auto-appends remaining data.

Smartsheet reported a 40%+ increase in form fills, 84% increase in MQLs, 26% increase in opportunity rate, and 59% increase in win rate after implementing it. Unlike Clearbit's HubSpot-only approach, FormComplete works across CRM and marketing automation platforms.

The intelligence layer changes the value proposition

Clearbit enriches records. LeadIQ finds contacts.

Both are useful capabilities. But neither connects them to a broader understanding of why deals move or stall.

ZoomInfo's GTM Context Graph, an intelligence layer that processes 1.5B+ data points daily, fuses third-party data with your CRM records, conversation intelligence from Chorus, email threads, and behavioral signals.

The result: AI that understands the context behind your deals rather than just presenting data.

As ZoomInfo's CPO Dominik Facher writes: "The CRM recorded the state change. It has no record of why it happened."

The intelligence layer captures the decision context behind pipeline movement (executive sponsorship entering at a specific stage, ROI-focused questions predicting deal acceleration, competitive mentions indicating risk) and makes it available across GTM Workspace for sellers, GTM Studio for marketers and RevOps, and APIs/MCP for custom applications.

This isn't a feature either Clearbit or LeadIQ competes with, because it requires assets neither platform has: conversation intelligence, multi-channel behavioral data, and two decades of data unification infrastructure.

Access and integration philosophy

Clearbit is HubSpot or nothing.

The product is exclusively available inside HubSpot. No API, no integrations with other CRMs, no export of intent signals to ad platforms or data warehouses. For HubSpot-committed teams, this is simplicity. For everyone else, it's a non-starter.

LeadIQ integrates broadly but at varying depths.

Salesforce gets the native Managed Package with duplicate detection and custom field mappings. HubSpot gets a Workato-mediated recipe. Sales engagement tools (Salesloft, Outreach, Gong, Groove, Nooks, Orum) get one-click enrollment from the Chrome extension. The GraphQL API enables custom workflows, and there's a Clay integration for waterfall enrichment.

ZoomInfo treats access as a core architectural principle.

The same data and intelligence are available through three paths: APIs and MCP for any tool, database, or AI agent; GTM Workspace for sellers; and GTM Studio for marketers and RevOps.

The App Marketplace lists 120+ integrations including Salesforce, HubSpot, Dynamics, Snowflake, and data warehouse platforms. API access is included in all relevant plans, and the MCP server connects to AI assistants like Claude and ChatGPT.

CEO Henry Schuck described a large financial services firm building an internal app using ZoomInfo's MCP server, calling it "a surface area we would never see before."

The difference matters in practice: Clearbit locks your data inside HubSpot. LeadIQ's data flows into CRMs and sequencers. ZoomInfo's data flows into anything you build.

Pricing comparison

Clearbit/Breeze Intelligence doesn't have standalone pricing. It's embedded in HubSpot subscriptions.

Basic enrichment is included at no extra cost for Starter+ Core Seats. Advanced features (Buyer Intent, Smart Properties) consume HubSpot Credits, with Professional plans including 3,000 credits/month and Enterprise including 5,000 credits/month.

Source: HubSpot

Additional credits cost $10 per 1,000. Credits expire monthly with no rollover.

LeadIQ offers a permanent free plan (1 user, 50 credits). The Pro plan starts at $15/month per user on annual billing with credit volumes from 2,400 to 81,000 per year. Credit costs: 1 credit per email unlock, 10 credits per phone number.

Source: LeadIQ

Enterprise pricing is custom. Credits expire at the end of the subscription term with no rollover.

ZoomInfo uses custom-quoted pricing with no published dollar amounts. Different product lines (Sales, Marketing, Chorus) have tiered plans (Professional, Advanced, Enterprise) with different capabilities at each level.

ZoomInfo Lite is a permanent free tier with 10 monthly export credits, database access, and the Chrome extension. A 7-day free trial provides access to core features with no credit card.

The pricing comparison requires looking at total cost, not sticker price: Clearbit seems "free" until you factor in your HubSpot subscription. LeadIQ's $15/month entry is affordable but covers only prospecting; you'll need separate tools for intent, enrichment at scale, and outreach execution. ZoomInfo costs more but consolidates capabilities that otherwise require three to five separate vendors.

Security and compliance

All three platforms maintain enterprise-level security postures:

ZoomInfo holds the most comprehensive certification stack, which matters for regulated industries (financial services, healthcare) that require ISO 27701 or TRUSTe validation.

LeadIQ and Clearbit meet the baseline requirements most B2B companies need.

Clearbit and LeadIQ each solve a specific problem well.

Clearbit keeps HubSpot records complete.

LeadIQ helps reps find contacts fast. But go-to-market teams that need to connect prospecting, intent, enrichment, outreach, and intelligence into a single motion will find themselves stitching together multiple tools, managing multiple vendors, and losing signal fidelity at every integration seam.

ZoomInfo eliminates that fragmentation. One data foundation. One intelligence layer. Every access point. That's the difference between a collection of tools and a platform built for how revenue teams work.
