Best Clearbit API Alternatives 2026: After the HubSpot Move

Clearbit did not get worse. It got acquired. Since HubSpot folded it into Breeze Intelligence, the standalone Clearbit API is closed to new customers without a HubSpot contract, the free tier was sunset on April 30, 2025, and the Logo API shut down in December 2025.

That is why the search for a Clearbit API alternative looks different from most alternative searches. Nobody is leaving because the data was bad. They are leaving because the product moved into a CRM they do not use.

This page covers what changed, who has to migrate and who does not, nine alternatives compared on published pricing, and a migration plan for the two workloads Clearbit was best at: enriching a signup from an email, and enriching a company from a domain. Prices checked in September 2026.

Key Takeaways#

• Clearbit is now HubSpot Breeze Intelligence: from about $45 a month for 100 credits, on top of a paid HubSpot subscription. Standalone API access is closed to new customers.
• If HubSpot is your CRM, you may not need to move. If it is not, you have to, and the deadline already passed for the free tools.
• The two Clearbit workloads, email-to-person and domain-to-company, map to reverse-email and company-enrichment endpoints at several vendors.
• Website visitor identification, Clearbit's other strength, is a separate category. This page names who does it; DataForB2B does not.

What Changed: Clearbit to Breeze Intelligence#

HubSpot acquired Clearbit and rebuilt it as Breeze Intelligence, a set of enrichment and intent features inside HubSpot that consume HubSpot Credits. The public Clearbit APIs were deprecated for new customers, the free Clearbit tools ended on April 30, 2025, and the free Logo API followed on December 8, 2025.

Pricing moved with it. Third-party trackers put the entry at roughly $45 a month for 100 enrichment credits, about $0.45 a credit, and every plan requires a paid HubSpot subscription underneath. Existing enterprise API customers kept access under their contracts.

The user threads read the same way. One team on r/CustomerSuccess, two years in, described smoother HubSpot integration and a bill "around 15k a year" they were no longer sure about. A 40-person SaaS on r/appointmentsetter reported match rates "dropping hard, like 45% on average", and a Riveter post summarised the situation for everyone else: if HubSpot is not your primary CRM, "you essentially have to migrate."

Who Needs a Clearbit Alternative, and Who Does Not?#

You do not need to migrate if HubSpot is your system of record, your enrichment volume fits inside HubSpot Credits, and the fields you used are the ones Breeze exposes. The integration is tighter than it ever was, and staying is cheaper than rebuilding.

You do need to migrate if any of these are true: your CRM is Salesforce, Attio, Pipedrive or your own database; you called the Clearbit API from your product rather than from a CRM; you relied on the free tier or the Logo API; or your volume makes $0.45 a credit a budget line.

The third case is the one this page is for. A product that enriched signups by calling an API has no CRM to migrate into. It needs another API.

How Did We Evaluate These Alternatives?#

We scored each vendor on the two things Clearbit's API was used for, email-to-person and domain-to-company, plus whether it imposes a CRM, what it publishes as pricing, the plan that unlocks contact fields, and whether REST is joined by MCP and webhooks. Visitor identification is noted separately, because it is a different product.

The 9 Clearbit API Alternatives at a Glance#

Read the third column first. Clearbit's problem is the CRM it now requires. Eight of the nine rows impose none. Then read the visitor ID column, because it separates two products that Clearbit used to sell as one.

How Do You Replace Email-to-Person Enrichment?#

You replace it with a reverse-email endpoint: send the work email a user typed into your signup form, receive the person and, through their employer, the company. That is the exact shape of the Clearbit Enrichment call most products made, and it is the one that has no CRM to migrate into.

Our API exposes it as a dedicated endpoint that resolves a professional email to a full profile, the same response shape as a profile enrichment. It runs in your stack over REST or as an MCP tool, with no HubSpot underneath. One call:

curl -X POST 'https://api.dataforb2b.ai/enrich/reverse-email' \
  -H 'api_key: YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{ "email": "[email protected]" }'

The response carries current title, company, seniority and location, which is what a PLG onboarding flow needs to route the signup: founder at a 20-person startup to self-serve, VP at a 2,000-person company to a human. The endpoint is recent enough that we do not publish a per-call credit figure on this page; check the pricing page for the current number.

Here is what it looks like for a developer-tools startup with 300 signups a week. The form captures an email. A webhook fires the reverse-email call. The agent tags the 40 that match the ICP, drafts a one-line welcome that names the company, and routes them to a founder's inbox. The other 260 get the standard flow. No CRM was required to run that logic.

How Do You Replace Domain-to-Company Enrichment?#

You replace it with a company enrichment call keyed on the domain: firmographics, headcount and growth, funding stage and last round, from one request. Every vendor in the table does this. The differences are freshness, which fields are native, and what it costs on the plan you can afford.

Per operation, company enrichment returns employee count and growth over 1, 6 and 12 months, funding stage, last funding amount and date, and industry, on every plan. The growth and funding fields are the ones a lead-scoring model actually uses, and they are the ones a static record ages fastest on.

The mistake most teams make in this migration is to replace one enrichment call with one enrichment call and stop. Clearbit was often called once, at signup. A request-time API can also be called when the account is scored, when a deal opens, and when a champion changes jobs, because each call is priced on its own.

What About Website Visitor Identification?#

Clearbit Reveal, now Breeze Buyer Intent, identifies the companies behind anonymous website visits. It is a different product from enrichment, it depends on IP and cookie infrastructure, and this API does not do it. If Reveal was the reason you paid for Clearbit, the alternatives are in a different category.

rb2b identifies visitors at the person level for US traffic, Warmly and Vector do company and person de-anonymisation with intent layered on, and ZoomInfo's WebSights covers the enterprise end. Pair one of those with an enrichment API for the record itself.

Saying this plainly matters because the comparison lists on this SERP tend to blur the two. A team that migrates its enrichment and discovers on Monday that its visitor feed is gone has been sold half a migration.

Where Breeze Intelligence Still Wins#

Stay on Breeze if HubSpot is your CRM and your enrichment happens inside it. The workflows are native, the credits are one pool, and the buyer intent dashboard is included on paid tiers. For a marketing team living in HubSpot, nothing here is simpler.

Stay too if you are an existing enterprise API customer whose contract carried over. Rebuilding an integration that still works, to save a per-credit delta, is a real cost with no product gain.

The calculation flips when the CRM is not HubSpot, when the API was the product for you, or when $0.45 a credit meets a PLG signup volume. Then the migration is not optional, and the only question is where.

How Do You Migrate From Clearbit in Four Steps?#

You migrate by inventorying which Clearbit calls your product actually makes, mapping each to a replacement endpoint, running both in parallel on one week of real traffic, and cutting over when the field mapping holds. The parallel week is the step teams skip and regret.

1. Create a free account on app.dataforb2b.ai/signup and pull an API key. Inventory your Clearbit calls: email lookups, domain lookups, logos, Reveal. Logos and Reveal need a different vendor.
2. Connect the MCP server in Claude under Settings, then Connectors, at https://mcp.dataforb2b.ai/mcp. The same server works with Cursor, VS Code, ChatGPT and any MCP-compatible agent, which makes the field-mapping step a conversation rather than a spreadsheet.
3. Paste the prompt: "Here are 200 signup emails from last week with the Clearbit fields we stored. Resolve each email to a person and company, compare title, company name, headcount and industry against the stored values, and list every field where the two disagree."
4. Turn it into a scheduled routine on live signups for one week, then cut the Clearbit call over. See the current grid on the pricing page.

The disagreements in step 3 are the point. Some will be Clearbit staleness, some will be the new vendor's gaps. You want to know which before you switch, not after.

Clearbit built the reference product for signup enrichment, then moved into a CRM. If yours is not HubSpot, the work is an inventory, a parallel week and a cutover. Grab a key on the pricing page and start with the 200 emails.
