Clearbit vs. Cognism (vs. ZoomInfo): Which B2B Data Platform Should You Choose in 2026?

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 "Breeze Intelligence" suite, meaning your decision about Clearbit is now a decision about HubSpot. Cognism, meanwhile, has evolved from a European data provider 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?

In short, here's what we recommend:

Clearbit (now 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 (Reveal) 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.

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, 7x the industry standard, 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. However, Cognism doesn't publish pricing, lacks a built-in sales engagement layer, and its intent data comes from Bombora (a third-party source shared with competitors).

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.

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 Breeze Intelligence. The standalone platform, the free Chrome extension (Clearbit Connect), the free TAM calculator, and the Slack integration have all been shut down.

Source: Hubspot

What remains is a credit-based enrichment add-on that requires a paid HubSpot subscription before you can purchase enrichment credits. The smallest credit pack starts at roughly $45/month for 100 enrichments. Credits expire every 30 days without rollover.

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 (tech stack identification) 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.

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.

Source: Cognism

Cognism's compliance infrastructure is distinctive. The database is screened against DNC registries in 15 countries (UK, US, Australia, Germany, France, Ireland, Canada, Spain, Portugal, and more). 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.

Source: Cognism

The limitations are real, though. 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."

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 (via Chorus), 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.

Neither Clearbit nor Cognism has this layer. Clearbit enriches records. Cognism surfaces contacts and signals. ZoomInfo connects the intelligence to execution.

Intent data capabilities reveal fundamental differences

All three platforms claim intent data. The implementations are fundamentally different.

Clearbit focuses on first-party intent: identifying which companies visit your website by matching IP addresses to company profiles. This is useful for flagging active interest, but it only captures what happens on your site. If a prospect is researching competitors, reading industry reports, or comparing solutions elsewhere, Clearbit doesn't see it.

Cognism resells Bombora Company Surge intent data, which tracks content consumption across a cooperative network of 4,000 B2B websites. Cognism's advantage is pairing this intent with phone-verified contact data so you can immediately act on signals. The limitation is that Bombora is a shared source: ZoomInfo, 6sense, and others also integrate Bombora data, meaning Cognism's intent signals aren't proprietary.

Source: Cognism

ZoomInfo operates its own proprietary intent engine, tracking signals from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings sourced monthly. The exclusive feature is Guided Intent, which identifies the specific topics historically correlated with your closed-won deals rather than requiring you to guess which keywords matter. Add website visitor tracking (WebSights) and conversation intelligence from Chorus, and ZoomInfo captures intent across first-party, third-party, and conversational signals in a single platform.

The practical difference: Clearbit tells you a company visited your pricing page. Cognism tells you a company is researching your category. ZoomInfo tells you a company is researching your category, visited your pricing page, and the CFO on the last call asked ROI questions that match the pattern behind your closed-won deals.

CRM compatibility determines who can use what

This is a dealbreaker for many teams.

Clearbit requires HubSpot. Period. If your CRM is Salesforce, Pipedrive, Microsoft Dynamics, or anything else, Clearbit is not available to you. Even the legacy Salesforce integration has been deprecated following the HubSpot acquisition.

Cognism integrates with Salesforce, HubSpot, Pipedrive, Microsoft Dynamics, and Bullhorn, plus sales engagement tools like Outreach and Salesloft. The February 2026 launch of native 2-way HubSpot sync strengthened its HubSpot integration specifically. This CRM flexibility is a structural advantage over Clearbit.

Source: Cognism

ZoomInfo provides universal access across the broadest ecosystem: 120+ integrations spanning CRMs (Salesforce, HubSpot, Microsoft Dynamics), marketing automation (Marketo, Eloqua), sales engagement (Outreach, Salesloft), data warehouses (Snowflake, Databricks), and more. The API and MCP server extend this further, allowing any AI agent or custom tool to access ZoomInfo's data and intelligence programmatically.

For teams using multiple tools across their GTM stack, ZoomInfo's universal access means intelligence isn't siloed in one application. The same data and GTM Context Graph are available in every tool, every workflow, every AI agent.

Pricing models reflect different strategies

Each platform prices differently, and the model reveals their priorities.

Clearbit uses a credit-based add-on model on top of a mandatory HubSpot subscription. The entry cost is deceptive: the smallest enrichment pack costs roughly $45/month for 100 enrichments, but that requires a paid HubSpot plan. Credits expire monthly. One enrichment action costs 10 credits, and credits burn across enrichment, form shortening, and intent features. Annual contracts are standard, with no mid-term cancellation or downgrades.

Cognism uses custom-quoted seat-based pricing with two tiers: Grow (prospecting essentials) and Elevate (adds Diamond Data, intent data, and signals). No prices are published. Cognism emphasizes no credit ceilings, with unrestricted views and exports under a fair usage policy. Annual contracts are standard. Diamond Data verification and additional intent topics are available as paid add-ons.

ZoomInfo uses custom-quoted seat-and-credit-based pricing across three sales tiers (Professional, Advanced, Enterprise) and three marketing tiers. Credits are consumed on export, not on searching or viewing. ZoomInfo also offers ZoomInfo Lite, a permanent free tier with 10 monthly export credits, access to the B2B database, Chrome extension, mobile app, and website visitor reveals. This gives prospects a way to evaluate the platform without a sales call, something neither Clearbit nor Cognism offers.

None of these platforms are inexpensive for serious use. The question is what you're paying for: Clearbit charges for enrichment actions inside one CRM. Cognism charges for access to verified contacts and signals. ZoomInfo charges for a complete GTM intelligence platform that spans data, AI, and execution.

Data accuracy is tested at the point of action

Data accuracy claims are easy to make. What matters is whether the phone number rings and the email lands.

Clearbit is strongest at the company level: company attributes (industry, revenue, employee count) and technographic data (tech stack identification) are accurate and well-maintained. Users praise its form shortening and real-time enrichment speed. But contact-level accuracy, particularly for direct dials and mobile numbers, is consistently cited as a weak point in user reviews. Coverage gaps appear for small businesses and companies outside North America.

Cognism addresses the phone number problem directly through Diamond Data's human verification process. The independent finding that phone-verified numbers are 3x more likely to connect validates the approach. Cognism also maintains a strong 30-day refresh cycle for director-level contacts, keeping records current. The weakness is coverage depth: Cognism's database of 440M+ contacts is large, but for purely North American markets, ZoomInfo's verified phone number volume is significantly higher.

ZoomInfo operates an extensive verification pipeline: data from automated ML scanning of 28 million site domains daily, third-party partnerships covering 95 million businesses, a contributory community of 200,000+ ZoomInfo Lite users, and a Data Training Lab of 300+ human researchers. First-party data reaches up to 95% accuracy. The scale of 135M+ verified phone numbers means that for North American prospecting, ZoomInfo has more verified direct dials than Cognism's entire Diamond Data database.

Cognism holds a legitimate edge in European phone verification depth and DNC compliance breadth. ZoomInfo holds the edge in overall database scale, North American coverage, and multi-source verification infrastructure. Clearbit holds neither edge; its acquisition by HubSpot has shifted its focus from competitive data breadth to CRM integration depth.

Compliance and security comparison

All three platforms take compliance seriously, but their approaches differ.

Clearbit inherits HubSpot's compliance infrastructure. It supports GDPR and CCPA, offers data residency options, and does not send PII to analytics platforms. But compliance controls are now managed through HubSpot's settings, not a standalone Clearbit compliance interface.

Cognism has built the most visible compliance infrastructure of the three, particularly for European markets. Its database is screened against DNC registries in 15 countries, including first-to-market coverage in Italy. The platform holds ISO 27001, ISO 27701, and SOC 2 Type II certifications and operates a fully notified database within GDPR timeframes. For teams in regulated industries selling into Europe, Cognism's compliance is a genuine differentiator.

ZoomInfo maintains a comprehensive certification stack renewed annually: ISO 27001, ISO 27701, SOC 2 Type II, TRUSTe GDPR and CCPA validations. ZoomInfo is a registered data broker in California and Vermont and operates a dedicated Trust Center. For enterprise buyers requiring auditable compliance across both North American and international markets, ZoomInfo's certifications match Cognism's breadth.

Who has the better AI capabilities?

The AI story illustrates where these platforms are headed.

Clearbit's AI is limited to enrichment automation: real-time form shortening, background data population, and automated CRM updates. These are useful but narrow. There's no AI-powered prospecting, no account intelligence generation, no AI-drafted outreach.

Cognism introduced AI Search and AI Research in Sales Companion, allowing natural language querying and one-click account summaries. AI Recommended Leads surfaces daily top-three account and contact recommendations filtered by persona and verified phone number availability. These features reduce manual research time but don't extend to outreach generation or deal intelligence.

Source: Cognism

ZoomInfo's AI operates at a fundamentally different level because it's built on the GTM Context Graph. AI agents inside GTM Workspace handle account research, outreach drafting, CRM updates, and signal monitoring automatically. GTM Studio allows marketers to describe audiences in natural language and launch multi-channel plays that self-improve from engagement signals. The AI isn't just searching data; it's connecting CRM history, conversation transcripts, intent signals, and behavioral patterns to surface why deals move and what to do about it.

The difference: Clearbit automates data entry. Cognism automates contact discovery. ZoomInfo automates the intelligence behind go-to-market decisions.

Clearbit made sense as a standalone data enrichment tool. Inside HubSpot, it makes sense for HubSpot-native teams who don't need anything beyond enrichment. Cognism carved out a strong position for European-focused outbound teams who depend on phone-verified mobile numbers and regulatory compliance.

ZoomInfo occupies a different category. It's not just a data vendor. The GTM Context Graph connects the intelligence across your entire revenue operation, from the first intent signal to the closed deal, and makes that intelligence accessible through GTM Workspace, GTM Studio, or any external tool via API and MCP. For teams that want data and execution in one platform, with the AI to connect them, that's a structural advantage neither competitor can replicate.
