Honest Clearbit Review 2026: Best B2B Data Enrichment Tool Worth It?
Knowing who is visiting your website — the company, the industry, the revenue size, the technology stack — before they fill out a single form is one of the most powerful capabilities available to B2B marketing and sales teams. Clearbit is built to deliver exactly that, and this Clearbit review examines whether the platform genuinely transforms how revenue teams identify, qualify, and engage their best-fit prospects. The Clearbit review covers data enrichment, reveal, prospecting, intent signals, and integrations — everything that matters before you commit to a contract.
Clearbit was founded in San Francisco in 2014 and was acquired by HubSpot in 2023, a move that significantly changed the platform’s distribution and integration story. This Clearbit review covers the post-acquisition version of the product, now operating as Breeze Intelligence within HubSpot’s ecosystem alongside the legacy Clearbit API. Understanding what the acquisition means for pricing, access, and roadmap is a central part of any current Clearbit review — and this one addresses it directly.
This Clearbit review is written for the demand generation manager, the revenue operations leader, or the B2B marketing team evaluating data enrichment and website intelligence tools. Whether you’re comparing Clearbit against ZoomInfo, Apollo, or 6sense, or deciding whether the HubSpot-native Breeze Intelligence product serves your needs, this Clearbit review gives you the honest, evidence-based assessment you need. It covers every major capability and the post-acquisition context that shapes the current product.
VERDICT BOX
Overall Rating: 8.2 / 10
Best for: B2B marketing and sales teams — particularly HubSpot users — who need real-time data enrichment, website visitor identification, and prospect intelligence to improve lead quality and personalise outreach
Price: Breeze Intelligence (HubSpot-native): credit-based, starting from $0.04/credit; legacy Clearbit API: custom enterprise pricing
Verdict: Clearbit delivers some of the most accurate and comprehensive B2B data enrichment available — the reveal and enrichment capabilities genuinely transform how revenue teams understand and act on their pipeline. HubSpot users in particular will find the post-acquisition integration to be a significant advantage.

What Is Clearbit? Background for This Clearbit Review
Clearbit is a B2B data enrichment and intelligence platform originally founded in San Francisco in 2014. The company built its reputation on the quality and breadth of its data — covering firmographics (company size, industry, revenue, employee count), technographics (technologies a company uses), contact data, and website visitor identification. This Clearbit review covers a platform that has undergone significant change since its acquisition by HubSpot in late 2023, with the core capabilities now offered in two forms: as Breeze Intelligence natively inside HubSpot, and as the legacy Clearbit API for non-HubSpot users.
The core value proposition this Clearbit review evaluates is data enrichment at the point of capture and beyond. When a prospect fills out a form on your website, Clearbit enriches their record automatically — pulling in company revenue, employee count, industry, technology stack, and more — without requiring you to ask for that information in the form itself. Shorter forms with higher conversion rates, combined with richer lead records, is the fundamental outcome this Clearbit review tests.
The website reveal capability is equally central to this Clearbit review: Clearbit identifies the companies visiting your website — even those that don’t convert — using IP mapping and firmographic matching. This de-anonymisation of web traffic turns what was previously invisible intent data into a list of target accounts actively researching your solution.

Data Enrichment — The Foundation of This Clearbit Review
Data enrichment is where this Clearbit review begins, because it’s the capability that most directly impacts the quality of every other revenue team activity downstream. Clearbit’s enrichment API appends firmographic, demographic, and technographic data to any company or contact record in real time. You pass Clearbit an email address or domain, and it returns company revenue, employee count, industry classification, geography, technology stack, LinkedIn URL, job function, seniority level, and dozens of other data points — instantly.
This Clearbit review found the data quality to be among the strongest in the B2B intelligence category, particularly for mid-market and enterprise companies in English-speaking markets. The firmographic data is accurate for established companies, and the technographic data — identifying what software and infrastructure a company uses — is one of Clearbit’s most distinctive and high-quality datasets. For sales teams that sell into specific technology stacks (a CRM integration vendor, a Salesforce app, a cloud infrastructure tool), the technographic enrichment delivers an immediate qualification signal that no other data source provides as reliably.
The enrichment coverage this Clearbit review found to have gaps is smaller companies, companies outside the US and UK, and recently founded organisations. For B2B companies targeting the SMB market globally, data coverage can be inconsistent. For enterprise-focused teams targeting large companies in major markets, the coverage and accuracy is strong and consistent.
Clearbit Reveal — Website Visitor De-Anonymisation
Website visitor reveal is one of the most commercially impactful features in this Clearbit review. Clearbit’s Reveal product identifies the companies visiting your website in real time — even when those visitors don’t fill out a form or provide any personal information. Using IP mapping combined with Clearbit’s company database, the platform matches web sessions to company records and surfaces firmographic data about each visiting organisation.
This Clearbit review found Reveal to be genuinely powerful for demand generation teams running account-based marketing programmes. Rather than waiting for prospects to self-identify through form submissions, Reveal provides a daily or real-time stream of companies showing intent — visiting your pricing page, your product pages, or your solution pages — that can be routed to sales teams for follow-up, added to retargeting audiences, or used to personalise website experience.
The accuracy caveat this Clearbit review must note is meaningful: Reveal’s match rate depends on IP mapping, which is less reliable when employees work remotely using home internet connections or corporate VPNs. This Clearbit review found match rates of 20–40% for typical B2B website traffic — meaning a meaningful portion of visitors are identified, but the majority remain anonymous. For high-traffic sites, even a 20% match rate produces a significant volume of actionable company-level intelligence.
Clearbit Forms — Conversion Rate Optimisation
Clearbit’s form enrichment capability — now integrated into HubSpot forms as part of Breeze Intelligence — allows marketing teams to shorten their lead capture forms dramatically. Rather than asking for company name, company size, industry, and job title (all of which Clearbit can append automatically), forms can be reduced to just name and email address. Clearbit enriches the rest in real time at the moment of submission.
This Clearbit review found form shortening to be one of the highest-ROI applications of Clearbit’s data. Conversion rate improvements of 15–40% are consistently reported when forms are reduced from 8–10 fields to 2–3 fields, and the data completeness of the resulting records is higher than before because Clearbit’s enrichment is more accurate than self-reported form data. For marketing teams where form conversion rate is a key performance metric, this Clearbit review found this single capability often justifies the platform cost.
Clearbit Prospecting
Clearbit’s prospecting feature allows sales and marketing teams to build target account and contact lists using Clearbit’s database as the source, filtering by firmographic criteria (industry, employee count, revenue range, geography), technographic criteria (uses Salesforce, uses AWS, uses HubSpot), and behavioural signals (has visited your website, is in a similar profile to your best customers). This Clearbit review found the prospecting capability to be well-integrated with the enrichment and reveal data — the same data quality that powers enrichment also powers prospecting.
For sales teams that need to build outbound target lists without a dedicated tool like ZoomInfo or Apollo, this Clearbit review found Clearbit Prospecting to be a viable alternative — particularly for HubSpot users who can work entirely within the Breeze Intelligence interface. The contact data quality is strong for decision-makers at target companies, though email verification and deliverability should be tested before using Clearbit-sourced contact data for high-volume outbound.
HubSpot Breeze Intelligence Integration
The most significant development in any current Clearbit review is the HubSpot acquisition and the resulting Breeze Intelligence product. For HubSpot Marketing Hub and Sales Hub users, Breeze Intelligence brings Clearbit’s enrichment and reveal capabilities natively into the HubSpot platform — no separate API integration required, no data passing between systems, and no separate contract to negotiate.
This Clearbit review found the Breeze Intelligence integration to be one of the strongest arguments for the platform for existing HubSpot customers. Enriched contact and company data surfaces directly in HubSpot contact records, lists can be built from enrichment attributes natively, and website visitor identification flows into HubSpot workflows automatically. For HubSpot users who previously used Clearbit via API integration, this Clearbit review found the native integration to be a significant workflow improvement.

| Product | Pricing Model | Notes |
|---|---|---|
| Breeze Intelligence (HubSpot) | Credit-based from $0.04/credit | Available as HubSpot add-on; credits consumed per enrichment |
| Clearbit API (legacy) | Custom enterprise pricing | For non-HubSpot users; requires sales engagement |
| Reveal (standalone) | Custom pricing | Company-level website visitor identification |
| Prospecting | Included with enrichment plans | Varies by contract |
This Clearbit review found the pricing to be one of the more complex aspects of the platform to evaluate, partly because the post-acquisition product structure creates two distinct paths. HubSpot users access Breeze Intelligence through a credit-based model — each contact enrichment or reveal match consumes credits, with packages starting at $0.04 per credit. Non-HubSpot users accessing the legacy Clearbit API are directed through an enterprise sales process with custom pricing. This Clearbit review recommends HubSpot users evaluate Breeze Intelligence pricing through the HubSpot marketplace, and non-HubSpot users contact the legacy Clearbit team directly for pricing on the API product.

- Companies targeting SMBs in non-English-speaking markets — Clearbit’s data coverage is strongest for larger companies in English-speaking markets
- Teams that need built-in contact sequencing alongside enrichment — Clearbit is a data layer, not a sales engagement platform

Get a Free Marketing Quote →Clearbit Review: Frequently Asked Questions
Q: Is this Clearbit review recommending it for all B2B teams? This Clearbit review recommends Clearbit most strongly for HubSpot users and for B2B teams focused on mid-market and enterprise targets in English-speaking markets. For teams not using HubSpot or targeting SMBs globally, Apollo.io or ZoomInfo may deliver better value depending on budget and use case.
Q: What happened to Clearbit after the HubSpot acquisition? This Clearbit review found that following HubSpot’s acquisition of Clearbit in late 2023, the core Clearbit capabilities were rebranded as Breeze Intelligence within HubSpot. The legacy Clearbit API continues to operate for non-HubSpot customers. HubSpot users now access enrichment and reveal through the native Breeze Intelligence product rather than a separate integration. The acquisition has generally improved the experience for HubSpot users and created uncertainty for non-HubSpot users about the long-term roadmap of the legacy API product.
Q: How accurate is Clearbit’s data? This Clearbit review found Clearbit’s firmographic and technographic data to be among the most accurate in the B2B intelligence category for established companies in major markets. Data accuracy is highest for companies with 50+ employees in the US, UK, Canada, and Australia. For smaller companies, startups, and companies in other markets, coverage and accuracy are more variable. This Clearbit review recommends testing data quality on a sample of your specific target market before committing to a full deployment.
Q: How does Clearbit Reveal work? Clearbit Reveal uses IP-to-company mapping to identify the organisations behind anonymous website visits. When a visitor lands on your website, Clearbit looks up the IP address, matches it to a company in its database, and returns the company’s firmographic data. This Clearbit review found typical match rates of 20–40% for B2B website traffic — the remainder are consumer IP addresses, VPNs, or addresses not in Clearbit’s database. Match rates are higher for sites with predominantly corporate traffic.
Q: Does Clearbit integrate with Salesforce? Yes. This Clearbit review confirmed Clearbit integrates with Salesforce through the legacy API product, enriching lead, contact, and account records in Salesforce automatically. For HubSpot-Salesforce users who sync data between both platforms, Breeze Intelligence enrichment can flow through to Salesforce via the HubSpot-Salesforce sync.
Q: How does Clearbit compare to ZoomInfo? ZoomInfo has a larger contact database, stronger intent data, and built-in engagement tools including email sequences and dialler. Clearbit has superior technographic data, a native HubSpot integration as Breeze Intelligence, and a more accessible pricing model for teams that don’t need ZoomInfo’s full feature set. This Clearbit review recommends Clearbit for HubSpot-centric B2B teams and ZoomInfo for teams that need a comprehensive sales intelligence platform with built-in engagement capabilities.
Q: What are the best Clearbit alternatives? This Clearbit review points to ZoomInfo (largest database, enterprise pricing), Apollo.io (best self-serve B2B intelligence, strong for SMB and mid-market), 6sense (best intent data and ABM orchestration, enterprise pricing), and Lusha (strong contact data, more affordable). Our AI marketing tools category covers all of these.

Get a Free Marketing Quote →Conclusion: Final Clearbit Review Verdict
After completing a thorough Clearbit review, the platform’s position in the market is clear and has been meaningfully shaped by the HubSpot acquisition. For HubSpot users, Clearbit — now Breeze Intelligence — is the most compelling data enrichment option available: native integration, strong data quality, and a credit-based pricing model that’s more accessible than traditional enterprise data contracts. The firmographic and technographic data quality is consistently among the strongest in the B2B intelligence category, and the form shortening and website reveal capabilities deliver measurable pipeline impact.
For non-HubSpot users, this Clearbit review found the landscape to be more nuanced. The legacy Clearbit API continues to serve enterprise customers well, but the acquisition creates uncertainty about long-term product investment and roadmap outside the HubSpot ecosystem. Teams evaluating data enrichment without a HubSpot context should run a parallel evaluation of Apollo.io and ZoomInfo before committing to the legacy Clearbit API.
This Clearbit review’s overall recommendation: if you’re a HubSpot user who cares about data quality and technographic intelligence, Breeze Intelligence is a near-automatic addition to your HubSpot stack. If you’re not a HubSpot user, the evaluation is more competitive — and Apollo.io in particular deserves serious consideration before defaulting to the legacy Clearbit product.
