6 Best Clearbit Alternatives for B2B Data Enrichment in 2026

Clearbit no longer exists as a standalone product — HubSpot acquired it in late 2023 and absorbed it into their Breeze Intelligence suite, leaving thousands of SDR and RevOps teams scrambling for a replacement. If you were using Clearbit for real-time CRM enrichment, firmographic data, or technographic signals, you need a direct substitute. The good news is the alternatives have gotten significantly better since Clearbit's acquisition, and several of them do specific jobs better than Clearbit ever did.

What happened to Clearbit?

HubSpot acquired Clearbit in November 2023 and rebranded its core capabilities as Breeze Intelligence, a feature set embedded directly in the HubSpot CRM. If your team runs on HubSpot, some of what Clearbit did is now available natively — but it is no longer a standalone, CRM-agnostic enrichment API.

For teams on Salesforce, Pipedrive, or any other CRM, this effectively ends the relationship. The Clearbit API is being wound down, and existing contracts were not renewed on legacy terms after the acquisition was completed. What made Clearbit valuable — its clean API, real-time enrichment webhooks, and technographic data — has either been locked behind HubSpot's pricing or deprecated.

This matters because Clearbit had a specific architectural niche: it was developer-friendly, CRM-agnostic, and built around enriching inbound leads automatically. Its replacements are not all built the same way. Some are prospecting platforms first, enrichment tools second. Others are pure databases. Understanding the difference before you switch saves you from buying the wrong thing.

What should you look for in a Clearbit alternative?

The right Clearbit alternative depends on which part of Clearbit you actually used. Most teams used it for one of four things — and each maps to a different type of replacement.

Most tools below cover 2–3 of these use cases well and the rest superficially. If you need all four, you will likely run two tools in parallel — which is actually cheaper than Clearbit's enterprise tier was before the acquisition.

Also consider data freshness, GDPR compliance (critical for European outreach), and whether the tool offers an API or only a UI. If your RevOps team built workflows on top of Clearbit's API, a UI-only tool is not a replacement — it's a different product category.

What are the best Clearbit alternatives in 2026?

Here are the six alternatives worth serious evaluation, with an honest assessment of where each one wins and where it falls short.

1. Apollo.io

Apollo is the most direct Clearbit replacement for the majority of B2B sales teams. It combines a database of over 275 million contacts with enrichment, sequencing, and a native dialer — all on a single platform. For teams that used Clearbit primarily to build and enrich prospect lists, Apollo covers the same ground at significantly lower cost.

Where Apollo wins: breadth of data, pricing flexibility, and the fact that it combines prospecting and outreach in one tool. Where it falls short: the enrichment API is less developer-friendly than Clearbit's was, and data accuracy on smaller companies and non-US markets can be inconsistent. The free tier is usable for early-stage teams.

2. ZoomInfo

ZoomInfo is the enterprise-grade option and the most comprehensive B2B database available. It covers firmographics, technographics, intent data, and org charts, with significantly better compliance infrastructure than most alternatives for GDPR and CCPA requirements.

The honest caveat: ZoomInfo is expensive and the contracts are structured to lock you in. Gartner reviews consistently note that mid-market teams often find they're paying for depth they don't use. If you have a team of 10 SDRs and are replacing Clearbit, ZoomInfo is almost certainly overkill — start with Apollo and graduate to ZoomInfo if you hit its ceiling.

3. Lusha

Lusha is a strong alternative for teams that primarily used Clearbit for contact-level enrichment — direct dials and verified email addresses. Its browser extension approach makes it fast for individual reps doing research in LinkedIn, and its fill rates on phone numbers are among the highest in the category.

Lusha is not an Apollo replacement — it doesn't have Apollo's database depth or sequencing tools. Think of it as a focused contact enrichment layer you add on top of a CRM or prospecting tool, not a full platform.

4. Cognism

Cognism is the strongest Clearbit alternative for European markets. While Apollo and ZoomInfo have historically had thinner coverage outside North America, Cognism has built its database around EMEA data quality and GDPR compliance. If your ICP is European companies, Cognism's phone-verified mobile numbers and compliance posture make it the default recommendation.

"We switched from Clearbit to Cognism after the HubSpot acquisition and the difference in European contact quality was immediate — we were getting valid mobile numbers where before we had blanks or generic switchboards."

5. BuiltWith

BuiltWith is purpose-built for technographic intelligence. If your primary use for Clearbit was identifying which technologies a company uses — their CRM, their marketing stack, their hosting infrastructure — BuiltWith's data is the most comprehensive available. It crawls and indexes technology installations across millions of websites and updates that data continuously.

BuiltWith is not a prospecting platform. You use it to answer the question "which companies are using [tool X]?" and then export that list into your CRM or outreach tool. According to BuiltWith's own coverage data, the platform tracks over 108,000 web technologies across more than 673 million websites — making it the deepest technographic dataset available.

6. Stealery

If your outbound motion targets companies already using a specific competitor, Stealery is built specifically for that workflow. You type in a competitor name, and the platform returns a list of companies confirmed to be using that product — filtered by company size, location, and hiring signals. It's not a general-purpose enrichment tool, but for competitor-displacement plays it removes the manual research that usually burns hours per campaign. SDR teams using competitor-targeted lists consistently see reply rates 4–6x higher than generic outreach because the context is immediately relevant to the prospect.

Clearbit vs ZoomInfo: which is better for SDRs?

Clearbit and ZoomInfo were built for different buyer personas, and the comparison is less useful than it sounds. Clearbit was an API product designed for RevOps and engineering teams to enrich data programmatically. ZoomInfo is a sales intelligence platform designed for reps and managers to find and act on prospects directly.

For SDRs specifically, ZoomInfo is the better daily-use tool — the UI is built around prospecting workflows, the intent data helps prioritize accounts, and the Chrome extension makes research fast. Clearbit's advantage was under the hood: clean webhooks, high API reliability, and CRM enrichment that happened automatically without rep involvement.

The comparison most SDRs actually care about in 2026 is ZoomInfo vs Apollo, since both are now direct competitors in the outbound platform space. ZoomInfo's data is generally more accurate and more complete on enterprise accounts; Apollo is significantly cheaper and good enough for the majority of SMB and mid-market prospecting. Forrester's B2B data provider evaluations consistently rate ZoomInfo highest on data quality but note the cost-to-value ratio degrades for smaller sales teams.

Clearbit vs Apollo: what's the real difference?

Clearbit was an enrichment layer. Apollo is a prospecting platform. These are genuinely different products, and the switch from one to the other is not always a direct migration.

Clearbit's core loop was: inbound lead arrives → Clearbit enriches it with firmographic and technographic data → enriched record lands in your CRM. The rep never touched Clearbit directly. Apollo's core loop is: rep searches the database → builds a list → pushes contacts into a sequence. It's an outbound origination tool, not a passive enrichment layer.

Teams that want Apollo to do what Clearbit did — automatically enrich inbound leads in the background — need to use Apollo's enrichment API and webhooks, which are available but require setup. For RevOps teams comfortable with API configuration, it works. For teams that want a plug-and-play Clearbit replacement without engineering involvement, the setup friction is real.

Where Apollo unambiguously wins over what Clearbit offered: the price-to-volume ratio. Clearbit's enterprise pricing was steep for high-enrichment-volume use cases. Apollo's credit model is more forgiving for teams doing large-scale prospecting, and the fact that it includes sequencing means you're replacing two tools (Clearbit + an outreach tool) with one.

Which Clearbit alternative should you actually use?

The honest answer depends on your current stack and primary use case. Here's the decision tree most teams should use:

• You're on HubSpot and used Clearbit primarily for inbound enrichment: Evaluate Breeze Intelligence first — you may already have access.
• You need a full outbound platform with enrichment, sequencing, and database access: Apollo.io is the default. Start there.
• You're primarily targeting enterprise accounts and need maximum data depth: ZoomInfo, but budget accordingly and negotiate the contract length.
• You have significant European ICP coverage: Cognism over Apollo. The GDPR compliance and EMEA data quality gap is significant.
• You need to know which companies use a specific technology or competitor: BuiltWith for broad technographic research; Stealery if the goal is competitor displacement outreach specifically.
• You need contact-level enrichment (emails, direct dials) added to an existing list: Lusha as a lightweight layer on top of your existing stack.

Most teams replacing Clearbit will land on Apollo for 80% of their use cases and add one specialist tool — Cognism for Europe, Stealery for competitor plays, or BuiltWith for technographic research — depending on their go-to-market motion. That combination is both cheaper and more targeted than Clearbit's all-in-one pricing was at scale.

The teams that struggle after a Clearbit migration are usually the ones who try to find a single direct replacement and force it to do things it wasn't designed for. Use the table at the top of this article to match the tool to the job, not the other way around.
