The 4 best Clearbit (HubSpot Breeze Intelligence) alternatives

Clearbit built the data layer a lot of B2B marketing runs on: identify the company behind an anonymous website visit, enrich a form submission from an email address alone, and score accounts against your ideal customer profile. HubSpot acquired it in 2023 and it now ships as Breeze Intelligence inside the HubSpot platform, which is the single most important fact on this page — the standalone product people evaluated for years is now a component of somebody's CRM.

38
Bottom line

If you are on HubSpot, this is now the default and the decision mostly makes itself. If you are not, you are being asked to adopt a CRM to buy a data feature — and the point solutions below do the job without that. Run a trial on your own traffic before committing to any of them, because match rate varies more between vendors than any feature list suggests.

The cost

Sold as HubSpot credits rather than a standalone subscription, consumed per enrichment and per identified visitor, and effectively requiring a HubSpot subscription underneath it. That makes a like-for-like price comparison genuinely hard, which is itself worth knowing: teams evaluating this against a point solution are usually comparing a platform commitment to a tool. Checked 2026-08-01 — verify against HubSpot directly, because credit pricing changes more often than list pricing.

Why people consider an alternative

The acquisition is the reason most people are reading this. Clearbit as a standalone product with its own roadmap no longer exists, and if you are not a HubSpot customer the natural path is now to become one — which is a much larger decision than choosing an enrichment vendor. The second reason is match rate: IP-to-company identification works well for large companies on corporate networks and much less well for small companies and remote workers, and vendors differ enormously here, so the right question is not which is best but which performs on your traffic. The third is privacy — de-anonymising visitors sits in genuinely contested territory under GDPR, and legal teams increasingly have opinions about it.

When Clearbit (HubSpot Breeze Intelligence) is still the right call

Stay if you are a HubSpot shop. Breeze Intelligence enriching records natively inside the CRM your team already uses is worth real money in saved integration work, and no point solution matches that. Stay if data quality on mid-market and enterprise accounts is what you need, where Clearbit's dataset remains among the strongest. And stay if procurement values one vendor and one contract — a consolidated platform is a legitimate reason to accept a worse component, and pretending otherwise would not be honest.

Every alternative, compared

#1★ TOP PICK

RB2B

Person-level identification for US traffic, with a genuinely free tier.

38
SOURCE-AVAILABLEProprietary (hosted service)

RB2B identifies individual visitors — name and LinkedIn profile, not just the company — and pushes them to Slack in real time. That is a meaningfully different product from company-level tools, and the free tier makes it the cheapest way to find out whether visitor identification is useful for your business at all before anyone signs a contract. Two constraints are stated openly by the vendor and belong here: it covers US traffic only, and person-level identification is a stronger privacy claim than company-level, which is exactly why it is US-only. Run it past whoever owns privacy at your company before switching it on.

Strengths

  • +Person-level rather than company-level identification
  • +Free tier is genuinely usable — the cheapest way to test the premise
  • +Real-time Slack delivery, so leads reach a human immediately
  • +Fast setup: one script tag

Trade-offs

  • −US traffic only — useless for a primarily international audience
  • −Person-level identification carries real privacy and compliance questions
  • −Proprietary and hosted with no self-host path
  • −Narrower feature set than the platform tools
Free tier with a monthly identification allowance; paid plans above it. Checked 2026-08-01.

Plausible + your own enrichment

The honest self-hosted answer: analytics you own, identification you do not.

92
OPEN SOURCEAGPL-3.0SELF-HOSTLOCAL-FIRST 28kupdated 24 days ago

There is no open-source visitor-identification tool, and the reason is structural rather than incidental — the product is an IP-to-company database maintained commercially, not an algorithm anyone can reimplement. What you can own is the analytics layer underneath. Plausible is AGPL-3.0, self-hostable, cookieless and GDPR-friendly, and it will tell you what people did on your site without sending any of it to a third party. Pair it with manual enrichment on the accounts that matter and you have most of the value with none of the privacy exposure. Listed to be straight about where the line is: this is the only entry on the page you can actually run yourself, and it deliberately does less.

Strengths

  • +The only option here you can actually run on your own infrastructure
  • +AGPL-3.0, cookieless, no consent banner needed in most jurisdictions
  • +No visitor data leaves your servers — the privacy question disappears
  • +Roughly 1 KB script; measurably faster than the tracking-heavy alternatives

Trade-offs

  • −Does not identify visitors — this is the trade, stated plainly
  • −No enrichment, scoring or personalisation
  • −You supply the server and the maintenance
  • −Not a replacement if pipeline generation is the actual requirement
Free and open source to self-host. Plausible Cloud is paid from a small monthly fee.

#3

Dealfront (Leadfeeder)

The European option, built around GDPR rather than apologising for it.

41
SOURCE-AVAILABLEProprietary (hosted service)

Dealfront is the merger of Leadfeeder and Echobot, and its distinguishing feature is jurisdiction: it is a European company with European data handling, built for GDPR from the start rather than retrofitted. For a company selling into Europe — or one whose legal team has already asked hard questions about this category — that is frequently the deciding factor rather than a nice-to-have. It identifies companies rather than individuals, integrates with the major CRMs, and its European company data is the deepest here. Company-level only, which is both the privacy story and the functional limit.

Strengths

  • +European company with GDPR built in, not bolted on
  • +Deepest European company data of anything here
  • +Company-level only, which is the more defensible privacy position
  • +Strong CRM integrations and a usable free tier

Trade-offs

  • −Company-level only — no person-level identification
  • −Weaker US data than the American vendors
  • −Proprietary and hosted
  • −Interface is busier than the newer tools
Free tier with limited identifications; paid plans from a low monthly fee. Checked 2026-08-01.

Algomo

Identification plus what to do about it — personalisation and an AI SDR.

36
SOURCE-AVAILABLEProprietary (hosted service)

Algomo starts where the identification tools stop. It de-anonymises the visitor, then acts on it: adapting headlines, content and calls to action per account, running an AI inbound agent that qualifies and books meetings, generating personalised landing pages for outbound sequences, and syncing personalised copy to LinkedIn ads. The pitch is that identifying a visitor is worth nothing unless something changes as a result — which is a fair criticism of the category. Plans start around $200/month with no per-seat pricing. Note when auditing links: algomo.com currently redirects to newmode.ai, and the company still trades as Algomo.

Strengths

  • +Acts on the identification rather than just reporting it
  • +Website personalisation, AI SDR and ad personalisation in one platform
  • +No per-seat pricing — the whole team can use it
  • +Replaces several point tools, which is where the real saving is

Trade-offs

  • −Proprietary and hosted; your visitor data flows through their platform
  • −Broader scope means more to configure before it earns anything
  • −$200/month floor is above the point tools
  • −Same privacy questions as everything else in this category
From about $200/month, no per-seat pricing. Checked 2026-08-01.

Questions people ask

▸ What happened to Clearbit?

HubSpot acquired it in 2023 and it now ships as Breeze Intelligence inside HubSpot rather than as a standalone product. If you already use HubSpot that is an upgrade — native enrichment in the CRM your team lives in. If you do not, the practical effect is that buying this data feature now points you toward adopting a CRM.

▸ Is there an open-source visitor identification tool?

No, and the reason is structural. The product is a commercially maintained IP-to-company database, not an algorithm someone can reimplement, so there is nothing for an open-source project to build. You can self-host the analytics layer — Plausible is AGPL-3.0 — but the identification itself is only available from vendors.

▸ Is visitor de-anonymisation legal under GDPR?

It is contested rather than settled, and it depends heavily on what is identified and where. Company-level identification from an IP address is the more defensible position; person-level identification is a considerably stronger claim, which is why the tools offering it generally restrict themselves to US traffic. If you sell into Europe, involve whoever owns privacy at your company before you switch anything on. This is not legal advice.
