Clearbit vs. Cognism Comparison

If you're comparing Clearbit vs. Cognism for your B2B data needs, you're evaluating two platforms that have taken very different paths to solve the same problem: getting accurate company and contact data into the hands of revenue teams.

But the comparison is more complicated than it appears. Clearbit no longer exists as a standalone product. It was acquired by HubSpot in late 2023 and absorbed into the HubSpot Breeze Intelligence suite, meaning your decision about Clearbit is now a decision about HubSpot. Cognism, meanwhile, has evolved from a European-focused contact intelligence platform into a full sales intelligence platform with AI-powered prospecting.

Before you choose, ask yourself these questions:

• Are you already committed to HubSpot, or do you need a CRM-agnostic data solution?

• Is European data coverage and DNC compliance a priority, or is your focus primarily North American?

• Do you need a standalone data enrichment engine, or a platform that also helps your sellers find, prioritize, and engage buyers?

• How important are verified mobile phone numbers for your outbound calling strategy?

• Do you want a data tool that plugs into one CRM, or intelligence that works across your entire GTM stack?

• Are you primarily evaluating on verified mobile phone numbers for outbound calling, or on the breadth of data plus workflow execution?

In short, here's what we recommend:

Clearbit (now HubSpot Breeze Intelligence) is ideal for teams already running on HubSpot who want native data enrichment without third-party integrations. Its real-time API enriches records in milliseconds, its form shortening reduces lead capture friction, and its website visitor identification flags which companies are browsing your site. The tradeoff: Clearbit only works inside HubSpot. Standalone access, free tools, and integrations with other CRMs have been shut down. Credits expire monthly without rollover, and contact-level data (especially direct dials and mobile numbers) is weaker than competitors. For more detail on what you'll actually pay, see our Clearbit pricing breakdown.

Cognism serves revenue teams that need accurate, compliant contact data across both North America and Europe. Its Diamond Data phone-verified mobile numbers deliver a 20% connection rate, and its database is screened against DNC registries in 15 countries. The Sales Companion platform pairs this data with AI-powered account recommendations and signal-based prospecting. The limitations: Cognism doesn't publish pricing (meaning every evaluation starts with a sales call), lacks a built-in sales engagement layer, and its intent data comes from Bombora, a third-party source shared with competitors. For a full breakdown, see Cognism pricing.

Both platforms solve pieces of the B2B data puzzle. Clearbit enriches your HubSpot records. Cognism gets your SDRs accurate phone numbers in Europe. But neither platform connects data, signals, conversations, and execution into a single intelligence layer that tells your team not just who to call, but why a deal is moving and what to do next.

ZoomInfo is an all-in-one AI GTM Platform built on the most comprehensive B2B dataset in the industry: 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails. That data foundation fuels ZoomInfo's GTM Context Graph: an intelligence layer that unifies your CRM records, conversation transcripts, and behavioral signals with the 1.5B+ data points that ZoomInfo processes daily. This captures why deals move or stall, so the AI drafting your next email follow-up understands the concern behind the conversation, your next GTM play targets accounts matching your actual win patterns, and your next forecast reflects buying evidence rather than rep optimism. Your team can leverage this intelligence through the dedicated GTM Workspace for sellers, GTM Studio for marketers and RevOps, or APIs and MCP in any front-end. There's also a free entry point: ZoomInfo Lite gives you 10 exports per month with no credit card required.

If you want intelligence that works across your entire GTM motion, not just inside one CRM, see how ZoomInfo works.

Clearbit vs. Cognism vs. ZoomInfo at a glance

Clearbit is now a HubSpot feature, not a standalone product

This is the single most important thing to understand about Clearbit in 2026. Following HubSpot's acquisition in December 2023, Clearbit has been fully absorbed into HubSpot as HubSpot Breeze Intelligence. The standalone platform, the free Chrome extension (Clearbit Connect), the free TAM calculator, the Slack integration, and the Logo API have all been shut down or are in the process of being sunset.

The transition was not a soft rebrand. Clearbit built a reputation as the developer-friendly, marketing-ops-focused alternative to ZoomInfo, with a free-tier flywheel, an open API, and integrations across the MarTech stack. That product is gone. What exists today is a credit-based data enrichment add-on that lives inside HubSpot's platform, useful to HubSpot customers and irrelevant to everyone else.

What remains is a credit-based enrichment add-on that requires a paid HubSpot subscription before you can purchase enrichment credits. Per available third-party analysis, the smallest credit pack starts at roughly $45/month for 100 enrichments. Credits expire every 30 days without rollover. For a full analysis of what you can actually expect to pay, see our Clearbit pricing guide.

For HubSpot-native teams, the integration is useful. Enrichment happens inside HubSpot workflows without API configuration. Form shortening reduces lead capture forms to a single email field. Website visitor identification flags which companies are browsing your pages. The data flows directly into HubSpot properties, triggering automated lead scoring and routing.

But the ecosystem lock-in is severe. If you use Salesforce, Pipedrive, or any other CRM, Clearbit is no longer an option. Even HubSpot users face constraints: credits burn across multiple features (enrichment, form shortening, intent), and high-traffic websites can consume credits unpredictably fast.

Clearbit's data quality reflects its original strength: company attributes (size, revenue, industry) and technographic data are accurate and well-structured, with over 100 attributes from 250+ sources. But users consistently report that contact-level data, particularly direct-dial phone numbers and mobile numbers, is weaker than competitors. Coverage outside North America is limited, especially for smaller businesses.

Clearbit's G2 rating of 4.4/5 across 632 reviews reflects solid satisfaction for teams in its intended use case. But that intended use case has changed substantially since the HubSpot acquisition. Reviews predating 2024 describe a very different product: a standalone enrichment API with broad integration support. The current product is narrower. If you're evaluating Clearbit, the relevant reviews are the most recent ones from post-acquisition HubSpot customers, not the legacy base.

Cognism leads in European data and phone-verified mobile numbers

Cognism's defining advantage is Diamond Data: mobile phone numbers that have been verified by a human who actually called the number and confirmed the right person picked up. With 10 million+ phone-verified contacts, Cognism claims these numbers deliver a 20% connection rate compared to the industry standard of roughly 3%.

For outbound sales teams that live on the phone, this matters. Lead Forensics reported that Cognism converted 60% better than a US competitor for European data. ComplyAdvantage saw a 15% increase in conversion rate after switching. The Diamonds on Demand service, which phone-verifies a specific contact's number within 48 hours on request, has no direct equivalent from other providers. If your SDRs are burning through wrong numbers in European markets, that on-demand verification layer is a meaningful operational difference.

Cognism's compliance infrastructure is distinctive. The database is screened against DNC registries in 15 countries, including the UK, US, Australia, Germany, France, Ireland, and Canada. The company holds ISO 27001, ISO 27701, and SOC 2 Type II certifications and processes data under GDPR legitimate interest. For teams selling into European markets where regulatory compliance is a procurement requirement, Cognism removes a significant administrative burden.

The March 2025 launch of Sales Companion moved Cognism beyond pure data provision into sales intelligence. The platform surfaces AI-recommended leads, generates one-click account summaries, and overlays enrichment data on LinkedIn and corporate websites through a Chrome extension. Subscription-based pricing (Grow and Elevate tiers) replaced the old credit model, giving teams unrestricted views and exports subject to fair usage.

Cognism holds a 4.6/5 G2 rating from 2,415 reviews, reflecting strong satisfaction among its core audience of European sales and SDR teams. The volume of reviews also indicates meaningful market adoption, not just sample-size luck.

The limitations are real. Cognism doesn't publish pricing, meaning every evaluation starts with a sales call. There's no built-in email sequencing or sales engagement tool; you'll need Outreach or Salesloft alongside it. Intent data comes from Bombora Company Surge, the same third-party source several competitors also resell, so Cognism's intent signals aren't differentiated from what you'd get elsewhere. And while Cognism claims 90% coverage of director-level contacts in both Europe and the US, its competitive positioning consistently frames itself against US-centric tools, implicitly acknowledging that its North American depth doesn't yet match ZoomInfo's.

ZoomInfo operates at a different scale

The comparison between Clearbit, Cognism, and ZoomInfo isn't apples-to-apples. Clearbit is a data enrichment feature inside HubSpot. Cognism is a sales intelligence platform focused on prospecting data. ZoomInfo is an all-in-one AI GTM Platform that spans data, intelligence, and execution.

Start with the data. ZoomInfo's database covers 500M contacts and 100M companies, with 135M+ verified phone numbers (including 120M direct dials) and 200M+ verified business email addresses. That scale isn't self-reported marketing; in a Fortune 500 competitive RFP analyzing 25 million contacts across vendors, the independent consultant concluded that "no other competitor came even close." ZoomInfo also holds 133 No.1 rankings on G2 across categories including Sales Intelligence and Data Quality as of Summer 2025.

The data also extends internationally: 34M+ company profiles outside North America, 200M+ professional profiles outside NA, and 45M+ mobile numbers outside NA. In 2025 alone, ZoomInfo expanded international mobile coverage by 1.8 million numbers across six European markets. This positions ZoomInfo as competitive with Cognism in European markets while maintaining deeper coverage in North America than either competitor.

But data volume alone doesn't explain the gap. What separates ZoomInfo is the GTM Context Graph, an intelligence layer that processes 1.5B+ data points daily by fusing ZoomInfo's third-party data with a customer's CRM records, conversation intelligence, email interactions, and behavioral signals. The result is an intelligence layer that captures why deals move or stall, not just that they did.

For example, a CRM records that a deal moved to Stage 4. Chorus captures that the CFO joined the last call and asked about six-month ROI. ZoomInfo's intent data shows the company is researching a competitor. The GTM Context Graph connects all three signals to surface what actually matters: executive sponsorship just entered the deal at a stage that correlates with closed-won outcomes in your segment, but competitive research means the timeline is compressed. That intelligence flows directly into AI-drafted outreach, account prioritization, and forecasting inside GTM Workspace.

The results reflect it. Seismic, using ZoomInfo's GTM Workspace, reported 54% higher rep productivity and 11.5 hours per week saved. Snowflake built an account propensity scoring model on ZoomInfo firmographic and technographic data and saw 25% higher customer engagement rates and 2x higher new customer conversion rates. Neither outcome is achievable from a data enrichment feature inside a single CRM.

Access this intelligence through GTM Workspace for sellers, GTM Studio for marketers and RevOps, or via APIs and MCP in any front-end, including AI agents and developer workflows. The ZoomInfo MCP connects AI agents directly to ZoomInfo data, enabling agentic prospecting and enrichment workflows that neither Clearbit nor Cognism offers.

Which platform is right for your team?

The right answer depends on your stack, your geography, and what you need data to do.

Choose Clearbit (HubSpot Breeze Intelligence) if:

• Your entire revenue team already runs on HubSpot and you have no plans to change

• Your primary use case is marketing-ops data enrichment (lead scoring, form shortening, visitor identification)

• You have a small data operations budget and don't need verified phone numbers for outbound calling

• You're comfortable with HubSpot's credit-based model and monthly expiration

Choose Cognism if:

• Your SDR team focuses heavily on outbound phone prospecting in European markets

• GDPR compliance and DNC screening across 15 countries is a hard requirement for procurement sign-off

• You're already running Salesforce, HubSpot, Dynamics, or Pipedrive and need a CRM-agnostic data layer

• Phone-verified mobile numbers (Diamond Data) and on-demand verification (Diamonds on Demand) are your highest-priority data need

Choose ZoomInfo if:

• You need more than data: you need data connected to signals, conversations, and execution in one platform

• Your team sells globally, including North American depth plus growing European coverage

• You're consolidating point tools and want one platform for prospecting, intent, enrichment, engagement, and analytics

• You want an enterprise-grade compliance footprint (ISO 27001, ISO 27701, SOC 2 Type II, TRUSTe GDPR/CCPA) alongside scale

• You want a free entry point to evaluate before committing: ZoomInfo Lite gives you 10 exports per month at no cost

The honest summary: Clearbit and Cognism are both data tools. ZoomInfo is a GTM platform that includes the verified B2B data both are competing on, plus the intelligence and execution layers on top. If your evaluation is purely "which tool gives me the most accurate EU phone numbers for the lowest cost," Cognism is a legitimate answer. If your evaluation is "how do we build a GTM motion that compounds over time," the comparison shifts significantly in ZoomInfo's direction.

It's also worth noting that neither Clearbit nor Cognism offers a meaningful free entry point. Clearbit requires a paid HubSpot subscription. Cognism offers only a free data sample. ZoomInfo Lite gives any team 10 exports per month at no cost, with no credit card required, so you can test the data quality before committing to a contract.

Frequently asked questions

Is Clearbit still a standalone product in 2026?

No. Clearbit was acquired by HubSpot in late 2023 and fully absorbed into HubSpot Breeze Intelligence by 2025. Standalone Clearbit tools, including the free Chrome extension (Clearbit Connect), the free TAM calculator, and the Slack integration, were all sunset by December 2025. What remains is a credit-based enrichment add-on available only to paid HubSpot subscribers. If your team doesn't use HubSpot as its primary CRM, Clearbit is no longer a viable option.

How does Cognism Diamond Data compare to ZoomInfo's verified phones?

Cognism's Diamond Data includes 10M+ phone-verified contacts where a human called the number to confirm accuracy, claiming a 20% connection rate. ZoomInfo has 135M+ verified phone numbers, including 120M direct dials, verified through a multi-source pipeline with 300+ human researchers. ZoomInfo also carries 45M+ international mobile numbers outside North America, giving it global scale that Diamond Data's EU focus doesn't yet match. Cognism's Diamonds on Demand service, which phone-verifies a specific contact within 48 hours on request, has no direct ZoomInfo equivalent, making it a genuine differentiator for high-value EU prospects.

Which is better for European prospecting, Cognism or ZoomInfo?

Both have meaningful European coverage, and the right answer depends on use case. Cognism is the stronger choice if you need EU-first phone-verified mobile data and DNC compliance across 15 countries out of the box. ZoomInfo is the stronger choice if you need global breadth (34M+ international company profiles, 200M+ international professional profiles, 45M+ international mobile numbers outside NA) combined with the GTM Context Graph intelligence layer and platform-level compliance (ISO 27001, ISO 27701, SOC 2 Type II, TRUSTe GDPR/CCPA). For EU-only SDR teams focused on outbound calls, Cognism is a serious option. For enterprise GTM teams operating globally, ZoomInfo's scale and platform breadth typically wins.

Does ZoomInfo work with HubSpot?

Yes. ZoomInfo offers native HubSpot integration as part of 120+ integrations in the ZoomInfo App Marketplace, including Salesforce, Microsoft Dynamics, Pipedrive, Outreach, Salesloft, Marketo, and Snowflake. Unlike Clearbit, which now only works inside HubSpot, ZoomInfo is CRM-agnostic. You can enrich, prospect, and activate data across any tool in your stack without being locked into a single vendor's ecosystem.

What is ZoomInfo's GTM Context Graph?

The GTM Context Graph is ZoomInfo's intelligence layer that processes 1.5B+ data points daily by fusing ZoomInfo's B2B data with your CRM records, conversation intelligence, and behavioral signals. Rather than answering "who should I call?", it answers "why is this account ready to buy now, and what does my team need to know to close it?" Available at gtm.ai, it powers AI-drafted outreach, account prioritization, and forecasting across GTM Workspace (sellers), GTM Studio (marketers and RevOps), and APIs and MCP for developer and AI agent workflows. Neither Clearbit nor Cognism has an equivalent intelligence layer.
