Clearbit Alternative for Company Enrichment by Domain

A Clearbit alternative for company enrichment is any service that turns a domain into firmographic fields without needing Clearbit itself. Since HubSpot folded Clearbit into Breeze Intelligence, teams outside HubSpot have had to look elsewhere. The right replacement depends on which fields you use, how many lookups you run and whether you already pay for HubSpot.

What changed

According to BusinessMCP’s Clearbit alternative page, which is a vendor-published comparison, HubSpot acquired Clearbit and integrated it as Breeze Intelligence, the free Clearbit tools ended on April 30, 2025, and the free Logo API shut down on December 8, 2025. A September 2026 teardown on that page found no new self-serve Clearbit API signups, and says existing contracts reportedly still run with no published end date. It also says HubSpot documents no enrichment API for non-HubSpot systems. Treat these as claims to verify, and check HubSpot’s own Breeze page for the current position.

First question: are you already on HubSpot?

If you pay for a HubSpot plan, Breeze enrichment may already cover your need. The same page says Breeze enrichment is included in paid HubSpot plans and does not use HubSpot credits, with a cheaper route via a Sales Hub Starter seat at $20 a month ($15 billed annually), and says the better choice for HubSpot users is Breeze. Do not pay a second vendor for what you already have.

If you are not on HubSpot

You have three broad routes.

Route	Examples named by BusinessMCP	Good for	Watch for
Domain enrichment API	BusinessMCP and similar	Firmographic fields per domain, developer use	Field coverage, miss behaviour
Contact and intent platform	ZoomInfo, Apollo.io	Sales teams that need people data	Seat or credit pricing, contracts
Technology and bulk data	Wappalyzer, Coresignal	Tech stack or large datasets	Narrower or heavier scope

What BusinessMCP offers, and what it does not

Per its data API page, BusinessMCP’s company data API and its free company lookup takes a domain and returns company fields, works over REST or MCP outside HubSpot, and is priced per company found at $0.02, with no seat requirement and $5 free for 7 days. A lookup that finds nothing is not charged, and a miss returns found=false rather than guessed data.

The limits, which the page itself states: no revenue, funding or intent data; no on-demand crawling; no name-to-domain lookup, so you need a domain, URL or work email; people tools need a card and accepted terms and exclude people in the EU, EEA, UK, Switzerland and certain US states; and the product is young, with no account team or long track record. Other pages from the same vendor describe a tech_stack field, while this page says the lookup returns no technographics, so check the current API reference for what your account actually returns.

Key takeaway: an alternative that publishes what it cannot do is easier to trust. List your must-have fields and check each one against the reference before you switch.

How to compare alternatives

1. List the fields you use. Pull a week of Clearbit calls and tally which fields your systems read. Often it is five or six.
2. Check coverage on your domains. Run a sample of 100 through each candidate.
3. Check miss behaviour. Does it return blank, guess or error?
4. Check billing. Per call, per found record, per seat.
5. Check integration effort. REST, SDK, MCP, CRM connector.
6. Check terms. Data sources, region limits, retention.

Migration steps

BusinessMCP’s page outlines a short path that applies to most switches.

1. List current calls and the fields you actually use.
2. Create a key and switch to the new endpoint; use bulk for backfills. For the BusinessMCP request shapes see the curl walkthrough.
3. Route found=false to your existing “not enriched” path instead of retrying.
4. Run old and new in parallel on a sample and compare fields.
5. Cut over gradually, one workflow at a time.

Field mapping pitfalls

• Industry taxonomies differ. A “financial services” label in one tool may not match another’s categories, so map them in a lookup table.
• Employee data differs. Some tools give a range, some a count, some both.
• Missing revenue. If you used revenue fields for scoring and the new tool lacks them, you will need a different signal.
• Logos and brand assets. The Logo API is a separate service from firmographics, and its shutdown is not solved by a data API.

Cost comparison approach

Compare the paid BusinessMCP pricing page with any rival’s, and price per found record on your own hit rate, as in company lookup API pricing. Seat-based tools can be cheap if your team uses every feature and expensive if only one is used. The wider field is covered in best company lookup tools.

When not to switch

If your Clearbit contract still runs and meets your needs, there is no urgency except planning. If you are fully inside HubSpot, use what is included. Switching for its own sake costs engineering time. Plan a fallback because the future of a legacy contract has no published end date, and revisit the decision each renewal.

A sample evaluation plan for a data team

Week one: inventory. Write down every place Clearbit data enters your stack, such as a signup webhook, a CRM sync, a nightly job or an analyst’s notebook. For each, note the fields read and what breaks if they go blank. Many teams discover that one or two workflows carry most of the dependency.

Week two: parallel run. Send the same 200 domains to the incumbent and to one or two alternatives. Build a simple comparison sheet with one row per domain and columns for each tool’s name, industry, size and country. Mark disagreements and review a sample by hand to see who is right more often.

Week three: decide and stage. Pick the replacement per workflow, not globally. A signup form might use a fast per-call API while a sales team stays on a platform that includes contacts. Keep the mapping layer thin so you can change again.

Questions to ask any replacement vendor

• What do you return when you have no record?
• Which of my current fields do you not provide?
• How do you bill misses, retries and failed calls?
• What are your rate limits and deadlines?
• What happens to my data and keys if I cancel?
• How long have you operated, and what support is there?

The last question matters more than it sounds. A new vendor can be perfectly good and still lack the account team a large company expects. Weigh that against the flexibility of simple, published pricing.
