ZoomInfo vs Clearbit: Big Database vs API-First Enrichment
ZoomInfo is the broad enterprise data giant, Clearbit (now part of HubSpot) is the developer-friendly enrichment layer. How the two compare for a sales team.
, 3 min read, Sales tech
Key takeaways
- ZoomInfo is generally known as one of the largest, broadest B2B contact and company databases, sold as a wide suite spanning data, intent and engagement.
- Clearbit, now part of HubSpot, is typically known for API-first, real-time enrichment built for developers and product-led growth teams rather than as a standalone prospecting database.
- The choice usually comes down to whether you need a large searchable prospecting database or a lightweight enrichment layer wired into forms, your website and your CRM.
Two vendors that get compared for the wrong reason
ZoomInfo and Clearbit show up on the same shortlist often enough that people assume they're solving the same problem. They mostly aren't. ZoomInfo is generally known as one of the largest B2B contact and company databases on the market, built as a browsable, searchable prospecting tool with intent and engagement features layered on top. Clearbit, now part of HubSpot, is more narrowly known for API-first enrichment: taking a domain or email and instantly returning firmographic and technographic data, often used to enrich a form fill or identify an anonymous website visitor in real time.
ZoomInfo vs Clearbit at a glance
| Dimension | ZoomInfo | Clearbit (HubSpot) |
|---|---|---|
| Best for | Teams wanting one broad platform covering contact data, intent and engagement | Product-led and HubSpot-native teams wanting real-time, API-driven enrichment |
| Data focus | Large, broad B2B contact and company database plus a bundled intent layer | Firmographic and technographic enrichment via API, forms and website visitor identification |
| Price tier | Premium, among the pricier options in the category | Mid-tier, increasingly bundled into HubSpot plans |
| Typical buyer | Mid-market to enterprise revenue teams consolidating tools | Growth and marketing ops teams already invested in HubSpot |
Where ZoomInfo pulls ahead
If your team's core workflow is a rep browsing a database, building lists by filtering on title, industry and headcount, and pulling direct-dial phone numbers before a call, ZoomInfo's interface is generally built exactly for that. It is typically the stronger option when prospecting itself, not just data enrichment, is the job to be done, and when a team wants one platform doing contact data, some intent signal, and outreach tooling together rather than stitching several tools together.
Where Clearbit pulls ahead
Clearbit is typically the better fit when the workflow is automated rather than manual: enriching a lead the moment they fill out a form, scoring inbound leads before routing them, or identifying which companies are visiting your website even before they convert. That real-time, API-first design is generally what growth and product-led teams value it for, and it tends to fit naturally into a HubSpot-centric marketing and sales motion now that the two are combined.
The HubSpot factor changes the calculation
Since the acquisition, Clearbit's roadmap has generally moved toward deeper HubSpot integration, which is good news if you're already there and a real consideration if you're not. Teams running a different CRM should ask directly, in any sales conversation, how enrichment works outside the HubSpot ecosystem today, rather than assuming past reviews of Clearbit as a fully independent product still describe the current offering.
Which one should you pick
Pick ZoomInfo if your reps need to search and build target lists directly inside a database, and you want contact data, some intent signal, and engagement tooling under one login. Pick Clearbit if your priority is automating enrichment at the moment of a form fill or website visit, and especially if HubSpot is already your marketing and sales hub. Some teams genuinely use both, ZoomInfo for outbound list-building and Clearbit-style enrichment for inbound lead scoring, but that's a two-tool budget commitment worth justifying with actual conversion data rather than defaulting to "more data is better."
Frequently asked questions
- Is Clearbit still a separate product from HubSpot?
- Clearbit was acquired by HubSpot and its enrichment capabilities are increasingly folded into HubSpot's own tooling. Teams already on HubSpot generally get the most value; teams on other CRMs should confirm current standalone availability before assuming it works the same way it once did.
- Does ZoomInfo do real-time enrichment like Clearbit?
- ZoomInfo offers enrichment features and integrations, but it is generally positioned first as a searchable contact and company database with a bundled intent layer, rather than as an API-first, developer-centric enrichment tool the way Clearbit is typically known for.
- Which is better for a small sales team without an engineering resource?
- ZoomInfo's interface-driven prospecting workflow is generally easier for a sales team to use directly without engineering support. Clearbit's strengths are typically realized through API integrations and form enrichment, which usually benefit from at least some technical setup.
