Last updated: September 3, 2026

Important update: HubSpot acquired Clearbit in December 2023 and folded its enrichment tools into a new product called Breeze Intelligence. The standalone Free, Growth, and Business plans described in the original Clearbit pricing pages were phased out, with the free tier and several legacy tools discontinued by April 30, 2025. If you’re evaluating “Clearbit” today, you’re really evaluating Breeze Intelligence, which now requires an active HubSpot subscription and runs on HubSpot’s credit system rather than Clearbit’s old standalone billing. The plan details below reflect how Clearbit was historically priced and packaged, and we’ve flagged where that no longer applies.

Clearbit built its reputation on data enrichment, giving sales and marketing teams cleaner records on companies and contacts. That reputation is why so many buyers still ask what Clearbit costs, even though the product itself now lives inside HubSpot’s Breeze Intelligence.

Historically, Clearbit’s pricing was based on data enrichment volume and API requests. It offered a free tier, a Business Tier around $20,000/year, and a custom “Powered by Clearbit” tier, with contracts ranging from roughly $17,100 to over $80,700 depending on company size and negotiated terms.

Below, we break down how Clearbit’s plans used to be structured, what’s changed under Breeze Intelligence, and how it stacks up against alternatives worth considering if you need contact and company data outside the HubSpot ecosystem.

Key Takeaways

• Clearbit is now Breeze Intelligence: HubSpot absorbed Clearbit’s tools into its own product, and the free standalone plan and several legacy tools were retired by April 30, 2025.
• Historical Free Plan: The old free plan offered 25 monthly credits for lead discovery, website visitor identification, and list building in HubSpot, useful for small teams starting out. This is no longer available as a standalone offering.
• Historical Growth Plan: Previously priced between $150 and $275 monthly for 125 to 1,000 credits, this tier included all Free Plan features for businesses expanding lead generation.
• Historical Business Plan: Custom-priced and built for enrichment, lead scoring, form optimization, and targeted outreach at volume, this tier scaled with usage rather than a flat rate.
• Breeze Intelligence today: Pricing now runs on HubSpot’s credit system and requires a paid HubSpot subscription, so total cost depends heavily on which HubSpot tier you’re already on.

What is Clearbit?

Clearbit built its name in B2B marketing intelligence by providing detailed data on companies, contacts, and IP addresses. It helped marketing teams by delivering data for improving products, customizing outreach, and refining customer targeting.

The company built its reputation on real-time data about people and companies, helping businesses personalize interactions and simplify operations.

Its database historically covered tens of millions of companies and hundreds of millions of contacts, information useful for lead generation, scoring, and audience targeting.

Marketing professionals, sales teams, and data analysts made up its core user base, drawn in by integrations with CRM and marketing tools. Since the HubSpot acquisition, that functionality lives on primarily as Breeze Intelligence inside the HubSpot platform rather than as an independent product.

Clearbit Free Plan (Discontinued)

Clearbit’s former Free Plan provided 25 credits per month at no cost and was suited to individuals or small teams testing lead data enrichment.

Clearbit Business Plan (Legacy Pricing)

Key Features in Business Plan

What Breeze Intelligence Costs Today

Breeze Intelligence uses HubSpot’s credit system rather than Clearbit’s former standalone plans. The article describes it as an add-on that requires a paid HubSpot subscription, with entry-level access typically around $45 to $50 per month for a credit batch; confirm current eligibility, packaging, and pricing with HubSpot before budgeting, since these terms can change. Teams using Salesforce, Pipedrive, or another CRM should also verify whether the available Breeze Intelligence setup meets their integration needs, as the product is built around HubSpot.

Clearbit Pricing on Reddit

Reddit discussions about Clearbit’s pricing and alternatives reflect the platform’s pricing history before the HubSpot transition. A few points worth noting:

• Users reported Clearbit’s API service starting at $99 a month for 275 data enrichment requests, with charges applied per request regardless of success.
• Other threads cited quotes over $20,000 for up to 200,000 contacts, pointing to premium tiers for high-volume needs.
• Clearbit’s Enrichment Batch, priced around $0.10 per record, was described as one of the pricier line items in its old catalog.
• Historical pricing ranged from $99 to $999 per month across services, with the old Prospector plan reportedly running $999 a month or $12,000 a year.
• These figures are largely historical now. Since the Breeze Intelligence transition, buyers should confirm current terms directly with HubSpot rather than relying on older Reddit threads.

When Should You Pay for Clearbit or Breeze Intelligence?

Here are scenarios where moving beyond a free or entry-level tier tends to make sense, whether you’re on legacy Clearbit or evaluating Breeze Intelligence:

Enhanced Functionality for Serious Outreach

As your marketing and sales efforts become more strategic, a paid plan offers broader tools and data for outreach at scale, including deeper lead generation and enriched data insights.

Professional-Level Needs

If you’re in sales or marketing, paid tiers are built for you. They connect with CRM systems for better data analysis and typically come with stronger customer support.

Recruitment and Advanced Tracking

If you’re using platforms like LinkedIn for recruiting, richer data plans simplify finding and tracking candidates, making the recruitment process more efficient.

Team Collaboration and Scaling

As a sales or marketing team grows, better collaboration tools and support in paid tiers make it easier to scale operations and keep data sharing consistent across the team.

Cost-Effectiveness for Larger Teams

For teams expanding outreach and lead generation, paid tiers become more cost-effective at scale. Volume discounts can make a paid plan a sound investment as your team and data needs grow.

Features of Clearbit

Clearbit built a reputation as a sales intelligence tool designed to support B2B marketing and sales efforts. Here are its core capabilities, most of which now live inside Breeze Intelligence:

Target Account Identification

Clearbit’s Target Market builder went beyond a basic target account list, helping identify an ideal B2B target market by drawing on a wide range of B2B companies across the internet to build a broader pool of potential buyers.

Intent Revelation and Conversion

Clearbit’s tools could reveal the identity of anonymous website visitors, surfacing intent from high-fit companies visiting a site so teams could act on it quickly.

Contact Database Access

With access to a large B2B contact database, Clearbit helped teams connect with decision-makers in their target market. The old free tier historically included prospecting credits, though this specific setup is no longer offered as a standalone product.

HubSpot Integration

Clearbit’s deep integration with HubSpot is now the whole point of the product, since Breeze Intelligence lives natively inside the HubSpot CRM and simplifies exporting enriched, deduplicated data straight into marketing campaigns.

Global Coverage and Data Accuracy

Clearbit’s data historically covered the US, APAC, and EMEA regions, with an emphasis on deliverability and accuracy for B2B contact data.

Is Clearbit Worth The Price?

It depends heavily on whether you’re already committed to HubSpot. Clearbit’s enrichment data has long been praised for depth, particularly for targeting decision-makers at smaller companies.

Many users found its targeted advertising group features effective, though others questioned the value given the price, especially at higher volumes. That tension has only grown since the shift to Breeze Intelligence, which now requires a HubSpot subscription on top of the credit cost.

Looking at Clearbit alternatives, Swordfish AI is a strong option, particularly for teams that don’t run their stack through HubSpot or need direct-dial phone data alongside email. It offers a comparable enrichment and contact-finding service without requiring a specific CRM commitment.

Bottom line: if your team already runs on HubSpot, Breeze Intelligence may be worth evaluating on its current credit-based terms. If you’re on a different CRM or want more flexibility, weighing it against alternatives like Swordfish AI is worth the time before committing budget.

Swordfish AI is the #1 Clearbit Alternative

Swordfish AI stands out among contact data platforms as an alternative to Clearbit, built around a large database that includes cell phone data and verified business email addresses.

Swordfish AI says its carrier partnerships and matching algorithms are intended to help connect contact data with the right prospect. Evaluate these claims against your own data-quality requirements and testing.

Swordfish AI also highlights email validation and data from live partners as ways to help keep contact records current and reduce bounced emails. Results can vary, so assess performance with your own data and use case.

A practical advantage for Swordfish AI users is the ability to reach decision-makers directly, which matters for both sales outreach and recruiting.

Why Choose Swordfish AI Over Clearbit?

When weighing Swordfish AI against Clearbit, it comes down to what you actually need. Both have strengths, but for certain use cases Swordfish AI is the better fit:

Comprehensive Contact Information

Swordfish AI’s partnerships with cell phone providers help keep contact data current, reducing the odds of outdated or incorrect details, which matters for outreach efficiency compared to Clearbit.

Real-Time Data Verification

Swordfish AI emphasizes real-time data verification, so contact information stays current and the risk of using stale data drops significantly compared to Clearbit’s older enrichment model.

Integration Capabilities

Both platforms integrate with common CRM and email tools, but Swordfish AI isn’t tied to a single CRM ecosystem the way Breeze Intelligence is tied to HubSpot, which matters if your team runs Salesforce, Pipedrive, or another system.

Cost-Effectiveness

Swordfish AI’s pricing model may offer better value for small to medium-sized businesses or budget-conscious teams, especially now that Breeze Intelligence requires a paid HubSpot subscription just to access its credits.

If you want a full feature set without being locked into a specific CRM’s pricing tiers, Swordfish AI’s plans may be more accommodating.

Conclusion

Clearbit’s pricing structure, historically, offered reasonable value for teams wanting thorough, accurate business data. That value proposition has shifted now that the product operates as Breeze Intelligence inside HubSpot, with cost tied to HubSpot subscription tier plus credit usage rather than a standalone plan.

If you’re focused on high-quality leads, sharper sales intelligence, and more efficient marketing, and you’re already committed to HubSpot, Breeze Intelligence is worth evaluating on its current terms.

Before deciding, weigh your specific needs, your existing CRM, and your budget against what Breeze Intelligence actually offers today.

If you’re considering alternatives with a different mix of features and costs, particularly if you’re not tied to HubSpot, Swordfish AI is worth a look. It offers a different set of trade-offs that may fit various business needs better than a HubSpot-locked add-on.

Frequently Asked Question

Are there additional costs for API usage in Clearbit?

Historically, yes, Clearbit’s API pricing scaled with usage. Under Breeze Intelligence, cost is tied to HubSpot credits rather than a separate API bill, so usage still affects total spend.

Is there a free trial available in Clearbit?
