BuiltWith vs Clearbit Comparison

If you're comparing BuiltWith vs. Clearbit, you're trying to answer a more basic question: what kind of intelligence does my go-to-market team need?

These two platforms look like competitors on the surface. Both deal in B2B data. But they solve different problems in different ways, and choosing between them depends on questions most comparisons skip:

• Do you need to know what technologies a company uses, or do you need a complete profile of the company and its people?

• Is your primary goal building prospect lists based on tech stacks, or enriching records already in your CRM?

• Are you locked into HubSpot, or do you need a platform that works across any CRM?

• Do you need historical technology trend data going back decades, or real-time enrichment that keeps your records current?

• Is technographic intelligence your main use case, or one dimension of a larger go-to-market motion?

• Does your team depend on a single CRM like HubSpot, or do you need enrichment and intelligence that works across Salesforce, Dynamics, or a custom stack?

Here's what we recommend:

BuiltWith is the leading platform for website technology intelligence. It tracks 113,000+ web technologies across 478 million root domains, with historical data stretching back to 1985. If your sales motion depends on knowing exactly what tech stack a prospect runs (and you want to build lead lists filtered by technology, geography, spend, and vertical), BuiltWith delivers depth that few platforms match. The trade-off: it focuses almost entirely on technographic data. You won't find verified phone numbers, email addresses for individual contacts, or CRM enrichment beyond technology profiles. Pricing starts at $295/month, and the interface requires comfort with data-heavy exports and manual cleanup.

Clearbit (now Breeze Intelligence, following its December 2023 acquisition by HubSpot) enriches CRM records with firmographic and demographic attributes from a single email address or domain. It identifies anonymous website visitors, shortens forms to improve conversion rates, and keeps HubSpot records current with monthly refreshes. For HubSpot users, basic enrichment is included at no extra cost on paid plans. The limitation is absolute: Breeze Intelligence works exclusively inside HubSpot. No Salesforce. No Dynamics. No standalone API. Non-HubSpot teams are excluded entirely.

Both platforms specialize well in their areas. But most go-to-market teams need more than one dimension of intelligence: verified contact data, intent signals, technographics, company attributes, and the ability to act on all of it from whatever tools they already use. That's a different kind of platform.

ZoomInfo is an all-in-one AI GTM Platform built on a large B2B dataset: 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business email addresses. Its GTM Context Graph processes 1.5B+ data points daily, unifying this data with your CRM records, conversation transcripts, and behavioral signals to reveal not just what happened in a deal, but why it happened and what to do next. That intelligence is accessible through GTM Workspace for sellers, GTM Studio for marketers, RevOps, and GTM engineers, or via Enterprise API and ZoomInfo MCP in any third-party tool, including Salesforce, HubSpot, Dynamics, Snowflake, and custom AI agents.

If your go-to-market team needs verified contact data, technographic intelligence, intent signals, and execution workflows that work across any CRM -- not just HubSpot -- see how ZoomInfo compares.

BuiltWith vs. Clearbit vs. ZoomInfo at a glance

These platforms solve fundamentally different problems

BuiltWith and Clearbit both deal in B2B data, but they describe different things about a company and serve different workflows.

BuiltWith answers one question well: What technologies does this company use?

It tracks 113,000+ web technologies across nearly half a billion domains, scanning source code, DNS records, and server headers to build one of the most detailed technographic databases available.

For sales teams selling B2B SaaS, eCommerce solutions, or web services, this data is directly useful: you can find every company running a competitor's product, filter by geography and spending, and time your outreach around platform migrations.

Clearbit answers a different question: What do I need to know about this lead or company to qualify and route them?

Its enrichment engine takes a work email address and returns firmographic attributes (industry, employee count, revenue, seniority, tech stack at a basic level), then writes those attributes into HubSpot CRM fields. It serves inbound teams that need to score leads fast, not outbound teams building prospecting lists from scratch.

ZoomInfo answers both questions and more: Who are the right people to contact at the right companies, what signals indicate they're ready to buy, and what should I do about it?

It combines the technographic depth BuiltWith specializes in, the enrichment Clearbit provides, and adds verified contact data, intent signals, conversation intelligence, and AI-powered execution, all accessible from any tool.

For most go-to-market teams running Salesforce or a mixed CRM environment, Clearbit's HubSpot-only constraint is a hard blocker before the product comparison even begins. And BuiltWith's contact data, scoped to non-EU/CA domains only, means international teams cannot rely on it for prospect outreach. Neither limitation is a flaw in the products themselves -- both tools deliver real value within their defined scope. But the scope of each tool is precisely why most teams evaluating them end up looking for something broader.

BuiltWith leads in technology tracking depth

If your primary job is understanding the technology landscape, BuiltWith is hard to beat.

The platform's 41+ years of historical data (reaching back to January 1985) enables analysis that competitors can't replicate. You can track how technology adoption shifted over decades, identify when companies first implemented a tool, predict renewal windows based on implementation dates, and spot migration patterns before competitors react.

The recently launched Actionable Insights feature moves beyond static profiles to identify companies showing buying signals through active experimentation, platform migrations, and vendor churn. BuiltWith states its data comes entirely from first-party crawler scans -- no third-party sources -- which underpins its depth claim.

For agencies selling to eCommerce businesses, BuiltWith's tracking of 2 billion unique products across 26 million online stores provides another layer that neither Clearbit nor most competitors offer.

Where BuiltWith falls short is everything beyond technology data. The platform provides contact names, emails, and titles for businesses outside the EU and CA, but it is not a contact database.

BuiltWith strengths and limitations

Strengths:

• 113,760+ tracked web technologies across 414M domains with usage history back to 1985 -- the deepest public-web technographic database available

• Actionable Insights identifies technology-stack movement signals (trials, experiments, rebuilds) -- intent data that firmographic sources miss

• Self-service pricing from $295/month with no sales call required; free individual site lookups forever

• MCP integration for Claude AI and other MCP connectors; API and dataset delivery to Snowflake, Redshift, BigQuery, and Databricks

• CRM bulk sync to Salesforce, HubSpot, Dynamics 365, and Zoho (up to 300,000 records/day)

• Predictive Leads feature surfaces sites whose stack profile predicts adoption of a target technology before they switch

Limitations:

• No outbound contact prospecting database; contact names, emails, and titles are bundled with technographic exports and restricted to non-EU/CA companies only

• No CRM record enrichment beyond technographic attributes -- no firmographic or demographic fields

• Intent signals limited to technology-stack changes; no keyword-based buying intent at scale

• No conversation intelligence, GTM workflow layer, or AI-guided outreach

• No contact verification network comparable to multi-source first-party verification

Clearbit: enrichment for HubSpot teams

Clearbit, now Breeze Intelligence, is exclusively available inside HubSpot. That single fact shapes every evaluation question that follows.

For HubSpot users, Breeze Intelligence is genuinely strong. It enriches company and contact records with 40+ firmographic, demographic, and technographic attributes from a work email address or domain. It shortens forms by auto-filling fields Clearbit can already resolve. It identifies anonymous website visitors against your ICP and scores them for outreach. It refreshes records continuously, reducing the data decay that kills outbound productivity. The industry classification depth (6-digit NAICS, GICS, and SIC codes plus corporate hierarchy mapping) is among the best in the category. Clearbit holds a 4.4/5 rating from 632 G2 reviews, reflecting real user satisfaction among its target audience.

The constraint is absolute and non-negotiable: if your primary CRM is Salesforce, Dynamics, Zoho, or any other platform, Breeze Intelligence is not available. The legacy standalone Clearbit free tools -- Free Platform, Weekly Visitor Report, TAM Calculator, Clearbit Connect, and Slack Integration -- were sunset on April 30, 2025. The Logo API follows on December 1, 2025. Non-HubSpot teams are excluded from the product entirely, not just from specific features.

Clearbit (Breeze Intelligence) strengths and limitations

Strengths:

• Native HubSpot integration -- no additional vendor relationship, no separate contract, no implementation project beyond activating Breeze Intelligence in your HubSpot settings

• 40+ firmographic, demographic, and technographic attributes populated from a single email address or domain

• Dynamic Form Shortening -- auto-fills fields Clearbit can resolve so visitors see shorter forms, improving conversion rates

• Continuous CRM record refresh -- records update automatically without manual intervention

• IP-based buyer intent and anonymous visitor identification inside HubSpot Reporting

• Strong industry classification depth: 6-digit NAICS, GICS, SIC, plus parent/subsidiary corporate hierarchy mapping

• 4.4/5 on G2 with 632 reviews

Limitations:

• Exclusively HubSpot -- no Salesforce, no Dynamics, no standalone API, no non-HubSpot deployment path

• No contact prospecting database -- Breeze Intelligence enriches known records but cannot build prospect lists from scratch

• Standalone free tools sunset April 30, 2025; pricing transitioning to HubSpot Credits consumption model with limited public transparency

• No historical technographic data (BuiltWith goes back to 1985; Breeze Intelligence does not provide trend history)

• No conversation intelligence and no GTM workflow layer beyond HubSpot's native capabilities

Where both tools fall short

BuiltWith and Clearbit each deliver real value inside a defined scope. BuiltWith is the gold standard for technographic data. Clearbit/Breeze Intelligence is a strong HubSpot enrichment layer. But both tools specialize in one dimension of the go-to-market intelligence problem -- and that specialization is precisely the gap most teams run into.

Neither platform provides a verified outbound contact database at scale. BuiltWith's contact coverage is restricted by geography. Clearbit enriches records you already have. If you need to build a prospect list from scratch -- finding the right people at the right companies who are not yet in your CRM -- neither tool solves that problem.

Neither platform provides first-party intent signals at scale. BuiltWith tracks technology-stack movement. Clearbit tracks website visitors inside HubSpot. Neither surfaces cross-web buying intent research signals that indicate when an account is actively evaluating a category.

Neither platform works across the full enterprise CRM landscape. BuiltWith syncs to multiple CRMs for technographic data. Clearbit works only inside HubSpot. Neither provides the same depth across Salesforce, HubSpot, Dynamics, Snowflake, and custom AI agent environments simultaneously.

And neither platform connects data to execution. Knowing what technology a company uses, or what firmographic tier they fall in, is only the starting point. Acting on that intelligence -- drafting outreach grounded in deal context, prioritizing accounts based on behavioral signals, updating CRM automatically -- requires a reasoning layer above the data.

ZoomInfo covers all three dimensions

ZoomInfo is an all-in-one AI GTM Platform built to close the gaps that point-solution data tools leave open.

The data foundation covers what both BuiltWith and Clearbit specialize in, and then goes further: 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business email addresses, continuously refreshed by automated ML and 300+ human researchers. ZoomInfo tracks 30,000+ technologies across 200+ categories on 30M+ companies -- covering technographic intelligence at a scale that complements BuiltWith's depth for teams that need verified contact data alongside the tech stack profile.

Above that data sits the GTM Context Graph, an intelligence layer that processes 1.5B+ data points daily. It fuses ZoomInfo's B2B data with your CRM records, Chorus conversation transcripts, and behavioral signals to surface patterns that reveal not just what happened in past deals, but why those deals closed or stalled. That reasoning layer powers ZoomInfo's AI agents: automated outreach drafted from real deal context, account prioritization based on actual win patterns, and CRM updates that happen without rep intervention.

Access runs through any tool your team already uses. GTM Workspace gives sellers a single surface for prospecting, outreach, and deal intelligence. GTM Studio gives marketers, RevOps teams, and GTM engineers natural-language audience building, enrichment orchestration, and cross-channel activation. The Enterprise API and ZoomInfo MCP expose the full data and intelligence layer to custom-built AI agents, Snowflake pipelines, and any third-party tool -- not just HubSpot.

Redwood Logistics deployed ZoomInfo's data, intent, and enrichment capabilities together and achieved a 99% reduction in cost-per-click, a 310% increase in click-through rate, and saved 25 hours faster per week in operational overhead. That outcome -- across data quality, intent activation, and ops efficiency simultaneously -- is what a unified platform delivers that point solutions cannot.

"ZoomInfo is a no-brainer because it really provides me the qualified leads that I'm looking for, and I won't replace it for any other key player in the market," said a Director of Sales Operations whose team had previously evaluated multiple data vendors in a competitive RFP process.

CRM and ecosystem flexibility

The CRM compatibility difference between these platforms is not a minor integration detail -- it is often the decision.

BuiltWith integrates with Salesforce, HubSpot, Microsoft Dynamics 365, Zoho, Close, and Pipedrive for CRM sync. It pushes technographic and contact data into those systems via Bulk Sync (up to 300,000 records/day for Salesforce, HubSpot, Dynamics, and Zoho) and Lead Push (Salesforce and HubSpot). For data warehouse delivery, BuiltWith supports Snowflake, Redshift, BigQuery, and Databricks via Datasets. Its MCP integration connects to Claude AI and other MCP-compatible tools.

Clearbit (Breeze Intelligence) integrates exclusively with HubSpot. No Salesforce. No Dynamics. No Zoho. No standalone API. There is no workaround, no enterprise exception, and no roadmap signal from HubSpot suggesting this will change. The product strategy is explicitly to deepen HubSpot-native enrichment, not to expand to other CRMs.

ZoomInfo integrates natively with 120+ tools across CRMs (Salesforce, HubSpot, Dynamics), sales engagement platforms (Outreach, Salesloft, Apollo), marketing automation systems (Marketo, Pardot, HubSpot Marketing), data warehouses (Snowflake), and more. The Enterprise API and ZoomInfo MCP provide programmatic access for any custom environment. Integrations are direct API connections, not Zapier middleware dependencies.

For RevOps and GTM engineering teams evaluating consolidation potential -- replacing two or three point solutions with a single contract -- the CRM flexibility difference matters more than any individual feature comparison.

Intent signals: tech-stack movement vs. buying research

All three platforms surface some form of buyer signal. The signals differ in type, depth, and where they surface.

BuiltWith Actionable Insights identifies companies running trials of new technologies, actively experimenting with stack changes, or churning away from a platform your team sells to. These signals indicate a company is actively re-evaluating its technology stack -- a genuine buying trigger for SaaS sellers and eCommerce platform vendors whose ICP is already using a specific technology category. The limitation: signals are scoped to technology-stack behavior only, not broader buying research across the web.

Clearbit (Breeze Intelligence) buyer intent is HubSpot-native. It identifies anonymous website visitors via IP resolution and tracks research behavior inside HubSpot's reporting. For inbound-focused teams running HubSpot, this surfaces real signals at the moment of site engagement. Outside HubSpot, the intent data is not accessible.

ZoomInfo Intent tracks 210M IP-to-Org pairings and 6T+ keyword signals monthly, sourced from a proprietary first-party signal network rather than a single third-party cooperative. Guided Intent uses AI to recommend the accounts most likely to convert based on your specific win history and the intent topics your closed deals showed before they signed. ZoomInfo was named a Leader in the Forrester Wave for Intent Data Providers (Q1 2025), receiving the highest possible scores across eight evaluation criteria.

The difference in intent depth matters most for demand gen and RevOps teams. Technology-stack movement is valuable for sellers calling into specific tech categories. Broad keyword-research intent -- knowing that an account is actively researching your category, not just using a competitor's tool -- is what moves pipeline.

When to choose BuiltWith

BuiltWith is the right choice when technographic intelligence is the core of your sales or marketing motion:

• Your ICP is defined primarily by what technology companies use (eCommerce platforms, marketing stacks, specific dev frameworks, or SaaS categories)

• You need historical technology adoption data to time outreach around migrations and contract renewals

• You sell to eCommerce businesses and need product or store-level data (2 billion unique products tracked)

• Your team has a technical profile comfortable with data exports and CRM sync configuration

• You want self-service pricing transparency without a sales conversation

BuiltWith is not the right choice if you need verified outbound contact data at scale, enrichment across EU or CA companies, a full GTM workflow layer, or intent signals beyond technology-stack movement.

When to choose Clearbit (Breeze Intelligence)

Clearbit/Breeze Intelligence is the right choice under one condition: your entire team operates inside HubSpot, and HubSpot will remain your CRM for the foreseeable future.

Within that constraint, Breeze Intelligence delivers real value:

• Inbound teams that need to enrich and qualify leads arriving via HubSpot forms

• Demand gen teams scoring and routing leads based on firmographic fit and website intent

• HubSpot admins managing CRM data quality without adding a separate enrichment vendor

• Marketing operations teams building HubSpot workflows triggered by ICP-fit and intent signals

Clearbit is not the right choice for Salesforce-based teams, mixed-CRM environments, teams needing outbound prospecting capability, or organizations planning to re-evaluate their CRM stack. The HubSpot dependency is the single decision criterion that eliminates Clearbit from most enterprise evaluation shortlists.

When to choose ZoomInfo

ZoomInfo fits teams that have outgrown point-solution data tools and need a platform that works across the full GTM motion:

• Outbound sales teams that need verified contact data (direct dials, verified emails) alongside technographic intelligence in one platform

• RevOps teams consolidating vendor contracts and replacing two or three point solutions (a data tool, an intent tool, an enrichment tool) with a single integration footprint

• Demand gen teams that need intent data feeding multi-channel campaigns, not just HubSpot workflows

• GTM engineering teams building enrichment pipelines on Snowflake or custom AI agent architectures via the ZoomInfo MCP

• Enterprise organizations in Salesforce environments or mixed-CRM stacks where HubSpot-only solutions are a non-starter

ZoomInfo Lite provides a permanent free tier (10 exports/month) for teams that want to evaluate the data quality before a larger conversation. Paid plans operate on a consumption-credit model.

FAQ

Is BuiltWith the same as Clearbit?

No. BuiltWith tracks web technologies and builds lead lists based on tech stacks. Clearbit (now Breeze Intelligence) enriches CRM records with firmographic and demographic data inside HubSpot. They serve different workflows: BuiltWith is for technographic-led prospecting; Clearbit is for inbound lead enrichment and qualification. Neither is a direct substitute for the other.

What is Clearbit called now?

Clearbit was acquired by HubSpot in November 2023 and is being rebranded as Breeze Intelligence under HubSpot's Breeze AI platform. The transition is ongoing: standalone Clearbit free tools (Free Platform, Weekly Visitor Report, TAM Calculator, Clearbit Connect, Slack Integration) were sunset on April 30, 2025. The Logo API follows on December 1, 2025. The product now lives exclusively inside HubSpot as Breeze Intelligence.

Does BuiltWith have contact data?

Limited. BuiltWith provides contact names, emails, and titles for companies outside the European Union and California -- GDPR and CCPA restrictions apply. It is not a contact prospecting database. You cannot use BuiltWith alone to build a verified outbound list with direct-dial phone numbers or to prospect into EU or CA markets.

Does Clearbit work with Salesforce?

Breeze Intelligence -- the current Clearbit product -- works exclusively inside HubSpot's Smart CRM. Non-HubSpot teams cannot access Breeze Intelligence. The legacy standalone Clearbit product had Salesforce integrations, but that product surface is being sunset. There is no announced path for Breeze Intelligence to support non-HubSpot CRMs.

What is the best alternative to both BuiltWith and Clearbit for a team using Salesforce?

ZoomInfo is the primary alternative for Salesforce-based teams that need both technographic intelligence and contact enrichment. It offers 30,000+ technologies on 30M+ companies, CRM enrichment, verified contact prospecting across 500M contacts and 100M companies, native intent signals, and 120+ integrations including native Salesforce, HubSpot, and Dynamics connectors. See also: Clearbit pricing and Clearbit alternatives for additional comparison context.

What does ZoomInfo have that BuiltWith and Clearbit do not?

Three things neither platform provides on its own: first, a verified outbound contact database at scale (500M contacts, 135M+ verified phones, 200M+ verified emails) that works without CRM or geography restrictions. Second, first-party intent signals across keyword-based buying research signals at the scale of 6T+ monthly signals and 210M IP pairings -- not just tech-stack movement or HubSpot-native visitor data. Third, a connected execution layer: GTM Workspace for sellers, GTM Studio for marketers and RevOps, and APIs plus MCP for GTM engineers and AI agent builders -- so the intelligence connects directly to action without additional tools.
