Bombora vs. Clearbit (vs. ZoomInfo): Which B2B Data Platform Fits Your Go-to-Market Strategy in 2026?

If you're comparing Bombora and Clearbit, you're trying to answer a practical question: how do I find which companies are researching what I sell, and what do I do about it?

Before you pick a tool, these questions will shape the decision:

• Do you need standalone intent data that feeds into whatever tools you already use, or do you want intent signals built into your CRM?

• Is your priority knowing which accounts are in-market, or enriching the contact and company records you already have?

• Are you on HubSpot? If not, is Clearbit even an option for you anymore?

• Do you have the team and tech stack to act on raw intent data, or do you need a platform that handles both the intelligence and the execution?

• How important is it that you can reach verified contacts at the accounts showing intent, not just know the accounts exist?

In short, here's what we recommend:

Bombora is the standard for B2B intent data. Its Data Co-op of 5,500+ B2B media sites captures content consumption signals that 86% of competitors cannot access, and its Company Surge scoring identifies when an account's research activity spikes above its own historical baseline. Forrester named Bombora a Leader in Intent Data Providers for B2B (Q1 2025) and called it "the gold standard for account-level intent data feeds." But Bombora is a data layer, not an execution platform. It has no contact database, no outreach tools, no CRM, and no public pricing. You'll need separate tools to reach the accounts Bombora identifies.

Clearbit (now Breeze Intelligence by HubSpot) enriches CRM records and identifies anonymous website visitors. It fills missing company and contact fields from over 250 data sources, shortens web forms to boost conversions, and surfaces companies visiting your site. Gong saw demo requests increase by 70% after implementing Clearbit's form shortening. Since HubSpot acquired Clearbit in December 2023, the product is now available only inside HubSpot. If you're not on HubSpot, Clearbit is off the table.

Both tools solve pieces of the go-to-market puzzle. Bombora tells you who's researching. Clearbit enriches and identifies visitors inside HubSpot. But neither gives you the complete picture: intent signals tied to verified contacts, with the tools to act on them, accessible from any platform you use. That's the gap a broader solution fills.

ZoomInfo is a combined AI go-to-market platform built on a large B2B data foundation: 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails. Its GTM Context Graph, which processes 1.5B+ data points daily, combines this data with your CRM records, conversation transcripts, and behavioral signals to show the full context of your accounts. That context feeds AI that reveals not just what happened, but why, and what to do next. Your team can run sales motions from the GTM Workspace, launch go-to-market plays from GTM Studio, or power their own tools through the API and MCP in any other front-end.

Bombora vs. Clearbit vs. ZoomInfo at a glance

Bombora gives you the signal. Clearbit gives you the record. Neither gives you both.

The core difference between Bombora and Clearbit isn't quality or accuracy. It's what each product does.

Bombora answers one question: which companies are researching topics relevant to your business right now? Its Data Co-op tracks content consumption across 5,500+ B2B media sites, and Company Surge scoring detects when an account's research activity rises above its historical baseline across 20,100+ B2B topics. The output is a prioritized list of accounts showing elevated interest. That's it. No contact records, no email addresses, no phone numbers. You get the signal; you find the people yourself.

Clearbit answers a different question: what do I know about the companies and contacts already in my CRM? It enriches records with firmographic, demographic, and technographic data (industry codes, employee count, revenue, tech stack, job titles) and identifies anonymous website visitors by matching IP addresses to companies. Since becoming Breeze Intelligence inside HubSpot, it works only within HubSpot's CRM. The output is richer records and a list of companies visiting your site.

Both are valuable. But notice what's missing: Bombora identifies intent without contacts. Clearbit enriches contacts without third-party intent. Neither provides a prospecting database for finding new people at target accounts.

ZoomInfo provides all three in one platform. Its Buyer Intent data tracks signals from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings monthly. Those intent signals connect directly to a database of 500M contacts with 135M+ verified phone numbers and 200M+ verified business emails. When ZoomInfo identifies an account surging on a topic, you can see the buying committee, pull verified contact details, and trigger outreach, all without switching tools or combining data from multiple vendors.

Intent data: Co-op depth vs. signal breadth

Bombora's intent methodology stands apart. Its Data Co-op model means publishers voluntarily contribute anonymized behavioral data (content views, downloads, form fills, registrations) in exchange for aggregated insights. Because Bombora places a proprietary JavaScript tag on publisher pages, it captures engagement from gated and paywalled content that competitors relying on bidstream data miss entirely. 86% of the data in the Co-op is shared exclusively with Bombora, so no other intent provider can reproduce the same signals from the same sources.

For teams whose primary need is high-quality third-party content consumption signals, Bombora's Co-op is hard to replicate.

Clearbit takes a different approach to intent. Its Buyer Intent feature identifies companies visiting your own website using IP intelligence, then matches them against your ideal customer profile. A newer Research Intent feature tracks companies researching relevant topics across the broader web, with support for up to 20 topics per portal. This leans on first-party data: the strongest signals come from your own site traffic, supplemented by limited third-party research tracking.

ZoomInfo's Intent Data draws from a larger set of signals: 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings sourced monthly. Where Bombora tracks content consumption across publisher sites, ZoomInfo tracks broader digital behavior patterns. ZoomInfo also offers Guided Intent, which identifies topics historically correlated with closed deals in your pipeline, rather than requiring manual topic selection. Both ZoomInfo and Bombora were named Leaders in the Forrester Wave for Intent Data Providers for B2B (Q1 2025), with ZoomInfo receiving the highest possible scores across eight criteria and Forrester noting it had "the largest R&D investment of any provider in this evaluation."

The practical question is: what happens after you get the intent signal? Bombora requires you to pipe the data into a separate tool to find contacts and take action. ZoomInfo lets you act on intent right away because the contacts and execution tools are already there.

The HubSpot question changes everything for Clearbit

Before the acquisition, Clearbit was a CRM-agnostic API that served any tech stack. Developers loved it. It connected to Salesforce, Segment, Marketo, and dozens of other tools via clean REST APIs.

That flexibility ended in December 2023. Breeze Intelligence is available only inside HubSpot. There is no Breeze Intelligence API for non-HubSpot systems. The standalone Clearbit APIs, Chrome extension, free tools, and CRM-agnostic integrations were all sunset by April 30, 2025.

For HubSpot users, the integration works well. Enrichment lives inside the CRM. Basic enrichment (contact and company records) is included at no extra cost for all Starter+ seats. Continuous enrichment refreshes records monthly, also at no additional cost. Form shortening no longer consumes credits. For teams already committed to HubSpot, this is enrichment with no integration work.

For everyone else, Clearbit no longer exists as an option.

Bombora avoids this problem entirely. As a data layer with 100+ integrations across competing platforms (including 6sense, Apollo, Salesforce, HubSpot, LinkedIn, and Marketo), it works with whatever tools you already use. The tradeoff is that Bombora never handles execution. You always need another tool in the stack.

ZoomInfo integrates with Salesforce, HubSpot, Microsoft Dynamics, and 120+ partner applications. Beyond integrations, teams can access ZoomInfo's data through APIs and MCP in any front-end, including AI agents built on Anthropic Claude or Google. ZoomInfo's intelligence isn't locked inside any single CRM or platform.

Enrichment capabilities: filling the gaps

Clearbit's enrichment is its strongest feature. From a single email address or company domain, it returns 100+ B2B attributes from 250+ data sources: industry codes (6-digit NAICS, 8-digit GICS, and 4-digit SIC simultaneously), employee count, revenue, tech stack, corporate hierarchy, job title, seniority, and social profiles. Offering multiple industry classification systems in a single enrichment record is uncommon among data vendors and useful for teams running complex lead scoring and routing.

Within HubSpot, enrichment runs automatically on new records, refreshes monthly on existing records, and can be triggered manually, in bulk, or through workflows. The data feeds into HubSpot's lead scoring, workflow routing, and campaign segmentation. For a marketing team that lives in HubSpot, this is as frictionless as enrichment gets.

Bombora's enrichment covers only account-level firmographic and intent data. It does not provide person-level enrichment (job titles, email addresses, phone numbers, seniority). Its Identity and Enrichment product identifies anonymous website visitors and maps them to companies with a 74% match rate, but the output is company identification, not individual contact details.

Source: Bombora

ZoomInfo's enrichment covers both company and contact data at scale. Multi-vendor waterfall enrichment evaluates 25+ data sources and returns the highest-confidence result, included at no additional cost in GTM Studio. The platform enriches with 300+ company attributes, department org charts, technographic profiles of 30,000+ technologies across 30M+ companies, and verified contact information. Where Clearbit enriches what's already in your CRM, ZoomInfo also adds contacts you didn't know existed at accounts you're targeting.

From signal to action: the execution gap

This is where the comparison shifts from features to workflow.

Bombora's workflow: You receive weekly Company Surge reports showing which accounts are spiking on selected topics. You export that list to your CRM, sales engagement platform, or ABM tool. Your team then identifies contacts at those accounts (manually or through automation in those tools), researches them, writes messages, and starts outreach. Every step after the intent signal requires a different tool.

Clearbit's workflow: Within HubSpot, you see enriched records and a list of companies visiting your site. You can enroll companies into HubSpot workflows, trigger email sequences, or route them to sales reps. But buyer intent data is limited to your own website visitors (plus research intent for up to 20 topics), and the product offers no prospecting database. If the people you need aren't already in your CRM, Clearbit can't find them.

ZoomInfo's workflow: Intent signals surface accounts researching relevant topics. The GTM Context Graph (ZoomInfo's intelligence layer, processing 1.5B+ data points daily) combines those signals with CRM data, conversation intelligence from calls and meetings, and behavioral patterns to show why accounts are moving. In GTM Workspace, sellers see prioritized accounts with AI-drafted outreach reflecting the context of each deal. In GTM Studio, marketers describe audiences in natural language and launch multi-channel plays. The platform handles prospecting, outreach, CRM updates, and campaign orchestration in one system.

The difference matters. Seismic attributed 39% of active pipeline to opportunities identified or influenced by ZoomInfo signals and reported 54% productivity gains. Thomson Reuters increased closed-won deals by 40%. These results come from closing the gap between knowing an account is in-market and engaging the right people with the right message.

Pricing structures reflect different business models

Bombora has no public pricing, no free plan, and no self-serve option. Every engagement starts with a sales conversation. Products are sold modularly (Company Surge, Identity and Enrichment, Digital Audiences, B2beacon, Insights Suite), and pricing depends on topics, volume, and integrations. B2beacon is the one product available per-campaign without long-term commitments. For most products, expect an annual enterprise contract.

Clearbit (Breeze Intelligence) pricing is embedded in HubSpot's subscription model. Basic data enrichment is included at no extra cost for all Starter+ Core Seats. Advanced features like Buyer Intent and Smart Properties consume HubSpot Credits. Professional plans include 3,000 credits/month; Enterprise plans include 5,000 credits/month. Additional credits cost $10 per 1,000. Credits expire monthly with no rollover. The effective cost depends on your existing HubSpot subscription tier.

ZoomInfo uses custom-quoted, seat-and-credit-based pricing with three product lines (Sales, Marketing, Operations), each with Professional, Advanced, and Enterprise tiers. No public prices are listed.

However, ZoomInfo offers two free entry points that neither Bombora nor Clearbit match: ZoomInfo Lite is a permanent free tier with access to the B2B database, 10 monthly export credits, the Chrome extension, and WebSights Lite. A separate 7-day free trial provides broader access to core features. For teams evaluating options, the ability to test the platform before committing matters.

Data quality and compliance

All three companies take compliance seriously, but with different approaches.

Bombora collects consent in 100% of the billions of events it captures, with data collection practices that create business profiles, not profiles of individuals. It uses the IAB Transparency and Consent Framework v2.2, and because Co-op data originates from direct publisher relationships (not scraped or bidstream sources), Bombora argues its data is more privacy-durable as regulations tighten. However, security certifications like SOC 2 or ISO 27001 are not publicly listed.

Clearbit holds a SOC 2 Type 2 certification, is aligned with GDPR principles using legitimate interest as legal basis, and is registered as a data broker in California under CCPA. Infrastructure runs on AWS and GCP with TLS v1.2/v1.3 encryption in transit and AES-256 at rest. The Trust Center at clearbit.com/trust consolidates compliance documentation.

ZoomInfo carries the broadest certification set: ISO 27001, ISO 27701, SOC 2 Type II, TRUSTe GDPR and CCPA validations, all renewed annually. It is a registered data broker in California and Vermont and maintains a dedicated Trust Center. For enterprise buyers in regulated industries (financial services, healthcare, government contracting), ZoomInfo's certifications are a procurement requirement, not a bonus.

Who each platform is not built for

Understanding exclusions is as useful as understanding strengths.

Bombora is not for small businesses without established go-to-market stacks (no self-serve, no public pricing, no contact database), B2C companies (the Data Co-op is purely B2B media), teams that want one platform for both intelligence and execution, or companies with primarily non-English-language target markets (signal depth is concentrated in North America).

Clearbit is not for anyone not on HubSpot (the product is HubSpot-only), teams that need a prospecting database for outbound list building, companies using Salesforce, Dynamics, or other CRMs, developers who relied on the legacy Clearbit API (it no longer exists as a standalone product), or early-stage startups on HubSpot Free (Breeze Intelligence requires at least a Starter subscription).

ZoomInfo is not for B2C companies (it covers only B2B intelligence), very small teams that need only basic enrichment (the platform's scope may exceed what a two-person startup needs), or teams looking for published, self-serve pricing without a sales conversation (paid tiers are custom-quoted, though ZoomInfo Lite is available immediately).

Bombora vs. Clearbit vs. ZoomInfo: Which should you choose?

The choice depends on what you already have and what you're trying to build.

Choose Bombora if:

• Third-party intent data quality is your primary buying criterion, and you're willing to pay for the best

• You already have a CRM, a sales engagement platform, and a contact data provider, and you need an intent layer to feed into that stack

• You want intent signals independent of any single platform vendor

• Your team has the resources to act on raw intent data through existing tools

• You're an enterprise with the budget for custom-priced data contracts and the go-to-market infrastructure to use them

• You want to identify companies visiting your website and route them into HubSpot workflows

• You're comfortable with HubSpot's credit system and don't need enrichment outside the HubSpot ecosystem

Explore Breeze Intelligence inside HubSpot.

Choose ZoomInfo if:

• You want intent signals, verified contact data, and execution tools in one platform instead of stitching together multiple vendors

• Finding and reaching the right people at in-market accounts (not just identifying the accounts) is your primary goal

• You need a platform that works with Salesforce, HubSpot, Dynamics, or any tool through APIs and MCP

• AI-powered prospecting, outreach, and deal intelligence would make your sales team more productive

• You want to try before you buy, with a permanent free tier or a trial that doesn't require a sales call first

Start with ZoomInfo Lite for free, or explore the full platform with a 7-day trial.

The question behind this comparison is how much of your go-to-market workflow you want one tool to handle. Bombora gives you the industry's best intent signals and trusts you to build the rest. Clearbit gives HubSpot users built-in enrichment and basic intent. ZoomInfo gives you the data, the signals, the contacts, the AI, and the execution tools, all drawing from one intelligence layer, accessible in any tool you choose to work in.

For teams that want to stop managing a patchwork of data vendors and start running their go-to-market from a single source of truth, ZoomInfo is the platform that makes that possible.
