Can Clearbit identify anonymous website visitors?
Clearbit Reveal resolved visitor IPs to companies, never to people — and no longer exists standalone. What replaced it, and what actually names a visitor.
No — and the more important answer is that the product you are asking about no longer exists in the form you remember. Clearbit Reveal resolved a visitor's IP address to a company, never to a named person. Clearbit has been acquired by HubSpot, its free visitor reporting was discontinued on 2025-04-30, and the surviving capability is HubSpot Breeze Intelligence buyer intent.

I'm Dag, co-founder of ContactLevel. We do not sell anonymous visitor identification, so this page will point you at other vendors. It exists because "can Clearbit identify anonymous visitors" is still one of the most-asked questions in this category and most of the pages answering it are describing a product that was retired last year.
What happened to Clearbit?
Clearbit's own homepage answers this in four words: "Clearbit has joined HubSpot!" (clearbit.com, checked 2026-07-29).
The retirement schedule Clearbit published is specific, and it matters because it removes the exact surfaces most people used:
| Product | Status | Date |
|---|---|---|
| Free Clearbit Platform | Discontinued | 2025-04-30 |
| Clearbit Weekly Visitor Report | Discontinued | 2025-04-30 |
| Clearbit TAM Calculator | Discontinued | 2025-04-30 |
| Clearbit Connect | Discontinued | 2025-04-30 |
| Clearbit free Slack integration | Discontinued | 2025-04-30 |
| Clearbit Logo API | Sunset | 2025-12-01 |

The Weekly Visitor Report is the one that matters here. That report — a list of companies that hit your site — was Reveal's public face for most teams. Clearbit names the replacement directly: "The buyer intent feature offers website visitor intent data you're accustomed to from the Weekly Visitor Report." That feature is HubSpot Breeze Intelligence.
If you are writing a stack diagram in 2026, "Clearbit Reveal" should not be a box on it.
What did Clearbit Reveal actually resolve?
A company. HubSpot still describes the surviving capability in a single line: "See what companies are visiting your website in the past hours, days, weeks, or months" (hubspot.com/products/clearbit, 2026-07-29).
That sentence is the whole answer to the headline question. The mechanism was reverse IP lookup: the browser hands over an IP address, the vendor matches it against a registry of ranges assigned to organisations, and an organisation name comes back. It never produced a human being.
Clearbit's other products get confused with this constantly, so to be exact:
- Enrichment turned an email or domain you already had into a fuller record. You had to bring the identifier.
- Prospector found contacts at a company. Those contacts were not necessarily the people who visited.
- Reveal was the visitor product, and it worked at the account level.
None of those three ever converted an anonymous session into a named individual. That distinction is the thing to hold onto, because the successor product inherits it.
Can Clearbit — or its successor — identify anonymous website visitors?
| Clearbit Reveal (as sold, now retired) | HubSpot Breeze Intelligence buyer intent | RB2B | ContactLevel | |
|---|---|---|---|---|
| Anonymous IP → company | Yes | Yes | Yes | No |
| Anonymous IP → named person | No | No | Yes, US traffic only | No |
| Requires the person already be in your audience | No | No | No | Yes |
| Geography | Global | Global | Person-level US only | Strongest in the US |
| Primary data source | Reverse IP lookup | Reverse IP lookup | Identity graph on browser/cookie signals | Your own audiences plus identity enrichment |
| Buyable standalone in 2026 | No | No — needs a HubSpot subscription | Yes | Yes |
| Published coverage figure | None | None | Contact-level 15-20% (Pro), 35-45% (Pro+) | n/a — 70-99% is a list-to-platform match rate |
Two of those cells deserve a sentence each.
"Buyable standalone: no." This is the change that catches former Clearbit customers. Breeze Intelligence is a HubSpot product sold against HubSpot subscriptions and HubSpot Credits. If your CRM is Salesforce or Pipedrive, you cannot buy the successor to your Clearbit visitor report on its own — you would have to adopt HubSpot to get it.
ContactLevel's 70-99%. That is not a visitor-identification coverage rate and comparing it to RB2B's 15-45% would be comparing two unrelated measurements. It is the share of a contact list that matches to real accounts when you sync it to an ad platform. B2B match rates unpacks the three different things the phrase gets used for, because vendors conflate them constantly.
What should you use instead?
Split the question, because one product no longer covers both halves.
→ For company-level reporting, globally. Leadfeeder / Dealfront is the direct like-for-like if you are not on HubSpot, with a published €0 tier. If you are on HubSpot, the prospects tool is already switched on for you at no extra cost and does the same reverse-IP job.
→ For named individuals, US traffic only. RB2B, Datamoon or a comparable identity-graph vendor. Read the coverage figure on the tier you would actually buy, not the homepage headline — the gap between those two numbers is the biggest trap in this category and deanonymizing website traffic works through a real example of it.
→ For enrichment of records you already hold. Contact enrichment covers the replacements for Clearbit's actual core competence, which was never visitor ID in the first place.
Where ContactLevel fits, and where it does not
Plainly: we are not a Clearbit Reveal replacement and we are not a website visitor identification tool.
ContactLevel names a website visitor only when that person is already in one of your ContactLevel audiences — synced from your CRM, uploaded, or built in-platform. There is no ContactLevel pixel that puts a name on a stranger. If you buy us for that, you will be disappointed in week two.
What we do is the half nobody sells you alongside identification. Once a tool hands you a name and a work email, you can email that person and you can call them. What you usually cannot do is advertise to them, because the work email in your CRM is not what LinkedIn, Meta, Google, Reddit and X match on. Nobody signs up to Meta with their work email. That gap is why enriched lists sync at 70-99% and raw work-email CSVs sync far lower.
So the honest architecture is a pairing:
- Identify upstream. Dealfront for company-level anywhere, RB2B or Datamoon for named people on US traffic.
- Enrich and activate downstream. Push those contacts into a ContactLevel audience, which maps the business identity to the personal identifiers ad platforms match on, then syncs to LinkedIn, Meta, Google, Reddit and X.
- Measure the click. We report clicks and website visits back at the individual person level. We do not report per-person ad impressions — that is not in the product today, and what we track is the dated statement of record.
At least one ContactLevel customer runs exactly this stack with the RB2B pixel as the upstream feed. It is a pattern we recommend, not a workaround we tolerate.
Published pricing is on /pricing: $1,000/month for 10,000 net-new contacts, $3,000/quarter for 50,000, or $10,000/year for 200,000, with a 14-day trial and 10,000 free contacts.
Where to go next
→ Can HubSpot identify anonymous website visitors? — the successor product, examined on its own terms.
→ Who is visiting my website? — the plain answer, including what Google Analytics contractually cannot tell you.
→ Deanonymizing website traffic — mechanisms, real coverage numbers, and the GDPR and CCPA position in 2026.
→ Clearbit alternatives — the enrichment side of the question, which is the part Clearbit was actually best at.
→ RB2B alternatives — mostly a page about activating RB2B rather than replacing it.
→ B2B match rates — why three different things get called "match rate".
