ZoomInfo vs Clearbit: Sales Intelligence vs Data Enrichment

Clearbit's pricing address now forwards to its homepage, and the homepage has one headline: "Clearbit has joined HubSpot!" So ZoomInfo vs Clearbit is no longer a comparison of two subscriptions. ZoomInfo is still sold as its own sales intelligence platform. Clearbit's data reaches new buyers as HubSpot's data enrichment, inside a HubSpot subscription, and the useful question is which of those two purchases fits the job in front of you.

ZoomInfo vs Clearbit: the quick answer

Pick ZoomInfo when the job is outbound prospecting: its sales page describes a contact database with direct dials, buyer intent, and a dialer and email tool. Pick Clearbit's data, now bought as HubSpot's data enrichment, when the job is completing the records and forms that already live in HubSpot. ZoomInfo's pricing page could not be read for this comparison, so no ZoomInfo price appears here.

Both have grown toward each other. ZoomInfo's own navigation lists website visitor tracking and web form optimization, which used to be Clearbit's territory, and the Clearbit data inside HubSpot still reveals which companies visit your site. The split that survives is scale of contact data against depth inside one CRM.

Understanding the Core Difference

ZoomInfo calls itself a go to market intelligence platform that helps businesses find, engage, and win customers more efficiently. Its product list runs from a company and contact database through buyer intent, website visitor tracking, conversation intelligence and a sales automation tool, and its about page says 30,000+ customers use it. Sales teams use it for prospecting, account research and buying signals.

Clearbit was marketing data infrastructure: enrichment, form shortening and visitor identification. HubSpot's Clearbit page now describes adding 100+ B2B data points to every contact or company record, dynamically shortening forms, and seeing which companies visit your website. HubSpot's knowledge base describes the same capability as data enrichment, powered by HubSpot's commercial dataset, third-party providers and publicly available information.

Database and Data Coverage

ZoomInfo publishes its coverage on more than one page, and the pages do not agree. Its data page says 500M+ professional profiles, 135M+ direct dial numbers and 122M+ companies. Its sales product page says 420M+ global contacts, 120M+ direct dials and 145M+ companies, and further down the same page, over 70M phone numbers and 174M-plus verified email addresses. Quote the page you are reading, and ask the rep which count the contract covers.

Figure	Data page	Sales page
People	500M+ profiles	420M+ contacts
Direct dials	135M+	120M+
Companies	122M+	145M+
Intent topics	4,500+	not listed
Verified emails	300M+	174M-plus
Phone numbers	not listed	over 70M

Clearbit does not sell a database to search. Its homepage describes enriching records you bring: global coverage across every country, industry codes down to 6 digit NAICS, GICS and SIC, corporate hierarchies, and normalised role and seniority. Neither clearbit.com nor HubSpot's Clearbit page mentions phone numbers.

So ZoomInfo offers the larger raw database, particularly for direct dials, and Clearbit's value sits in completing records as they arrive. That makes Clearbit most useful where data needs to flow automatically through HubSpot rather than be exported in bulk.

Deciding whether Clearbit fits your stack often means understanding what it does not do, and how it differs from revenue intelligence tools clarifies why teams pair rather than choose between them.

Pricing Comparison

ZoomInfo Pricing

ZoomInfo's pricing page returned HTTP 403 to a plain fetch and was refused to a headless browser on every attempt for this refresh, and so was its homepage. Its about page, which did load, carries Pricing, Contact sales and Free trial links. No ZoomInfo figure is stated here: the ranges quoted around the web are estimates rather than ZoomInfo's own numbers. Ask for the quote in writing, with the credit allowance and seat count it assumes.

Clearbit Pricing

Clearbit no longer sells a plan of its own. Its pricing address redirects to the homepage, which reads "Clearbit has joined HubSpot!" and offers a customer login. The data now arrives as HubSpot's data enrichment, which HubSpot's knowledge base lists as available with Starter, Professional and Enterprise subscriptions of its Marketing, Sales, Service, Data and Content hubs.

Clearbit's absorption into HubSpot raises a related question about pairing enrichment data with a dedicated pipeline tool, a topic covered in Clearbit's fit alongside pipeline software.

The credit side is narrower than it sounds. HubSpot's knowledge base says data enrichment does not consume HubSpot Credits, while smart properties do, and that credits are required for certain features. So the cost of Clearbit's data is mostly the HubSpot subscription it sits in.

Pricing Analysis

ZoomInfo is a sales conversation before it is a price, and a team without a data budget line will find that slow. Organisations running large outbound programmes are the ones that justify it.

Teams with smaller budgets facing similar tradeoffs might instead weigh enrichment tools built for lighter budgets, where free entry tiers make prospecting more accessible.

Clearbit is no longer a separate purchase. A team already paying for a HubSpot Starter subscription or above has the enrichment within reach; a team on another CRM would be buying HubSpot to get it.

Feature Comparison by Use Case

Outbound Sales Prospecting

ZoomInfo: Built for this use case. Its sales page describes building lists from 300+ attributes such as technology stack and funding data, direct dials, and a sales automation tool with a direct phone dialer and email. Sales teams can identify targets, reach contact information and export to their CRM in one click.

Clearbit: Limited prospecting functionality. It enriches leads you already have rather than discovering new prospects, although HubSpot's Clearbit page does describe building target market lists of B2B companies.

Winner for prospecting: ZoomInfo

Lead Enrichment

ZoomInfo: Its navigation lists CRM enrichment and an API that delivers data across business systems and workflows. The enrichment requires a ZoomInfo subscription.

Clearbit: Purpose-built for enrichment, and now native to HubSpot. HubSpot's knowledge base describes four ways to enrich: automatically for new records, one record at a time, in bulk from an index page or an import, and from the Intelligence tab. Form shortening remains the standout: when a visitor fills in a form, HubSpot checks the enrichment dataset and only displays the fields it cannot fill.

1HubSpot takes first name, last name and work email for a contact, or the domain for a company

2It searches its commercial dataset, third-party providers and publicly available information

3Where matching information is found, it updates the corresponding properties on the record

4Continuous enrichment keeps records current; automatic enrichment is off until an admin turns it on

Winner for enrichment: Clearbit, for teams on HubSpot

Intent Data

ZoomInfo: Its data page lists real-time intent signals from 4,500+ topics, and its sales page describes surfacing companies with high intent scores based on content consumption, technology signals and behavioural patterns.

Clearbit: Website-visit intent. Clearbit uses IP intelligence to identify the companies that visit your website, a form of first-party intent, and neither Clearbit page fetched for this comparison describes third-party topic intent.

Winner for intent: ZoomInfo

Website Visitor Identification

ZoomInfo: Lists website visitor tracking, sold as WebSights on its sales page, to discover decision-makers from companies exploring your website.

Clearbit: Reveal was built for this. HubSpot's Clearbit page describes seeing which companies visited in the past hours, days, weeks or months, who visited the pricing page and how many times, and whether they are already in HubSpot.

Winner for visitor identification: Clearbit for HubSpot users, though both list it

CRM and Marketing Automation Integration

ZoomInfo: Its sales page promises one-click export to your CRM, automatic record sync and connections to existing sales engagement tools, and its about page announces ZoomInfo data inside Microsoft Dynamics 365 and ZoomInfo MCP on Salesforce's AgentExchange.

Clearbit: It is part of HubSpot now, so the integration is the CRM itself.

Winner for HubSpot users: Clearbit Winner for other CRMs: ZoomInfo

Feature Comparison Summary

Use Case Recommendations

Pick ZoomInfo when

• Outbound prospecting is the job
• Calls need direct dials
• Topic intent decides which accounts come first
• Lists are built and exported in bulk
• The CRM is not HubSpot

Pick Clearbit in HubSpot when

• The CRM is HubSpot, Starter or above
• Forms should ask for less
• Inbound records need completing as they arrive
• The companies visiting your site matter

When to Use Both

Some organizations use ZoomInfo and Clearbit together. Sales teams use ZoomInfo for prospecting and account research, while marketing teams use Clearbit's data inside HubSpot for enrichment and visitor identification. This approach maximizes functionality but increases total data spend.

Teams weighing lighter-weight, budget-friendly alternatives might also compare Adapt.io against Lead411 for verified contacts and intent-based prospecting.

Data Quality Considerations

Both platforms invest in data accuracy, though their approaches differ.

ZoomInfo says its data is backed by proprietary AI and human validation, and its data page states a 96% email deliverability rate and 87% mobile number accuracy. Those are ZoomInfo's own figures. The scale of the database means some decay is inevitable.

Clearbit describes starting with the most precise data sources and then incorporating all other available sources to balance accuracy and coverage. The trade-off is that it completes records rather than supplying new ones.

Practical recommendation: Regardless of platform, implement verification in your workflow. Email validation, phone number verification, and regular list hygiene remain important even with premium data sources.

Getting Started and Switching

ZoomInfo is a procurement cycle: a demo or a free trial, then a quote. Clearbit's data inside HubSpot is a setting: a Super Admin configures enrichment, and automatic enrichment stays off for both contacts and companies until someone turns it on.

Moving from Clearbit to ZoomInfo makes sense when the sales team is scaling, needs bulk prospect data and phone numbers, or wants topic intent to shape the pipeline. Moving from ZoomInfo to Clearbit's data is rarer, and makes sense when the organisation is consolidating on HubSpot and enrichment of inbound records has become the main job.

Final Thoughts

ZoomInfo and Clearbit serve different primary purposes despite both being B2B data companies.

Choose ZoomInfo for: Enterprise sales intelligence, comprehensive database access, intent signals, phone coverage, and large-scale outbound prospecting

Choose Clearbit for: Marketing data enrichment inside HubSpot, form shortening, website visitor identification, and records that complete themselves as they arrive

The right choice depends on your primary use case, and now on your CRM. Sales-driven organizations running outbound programs typically get more value from ZoomInfo. HubSpot teams focused on enrichment and automation typically get more value from Clearbit's data.
