Alternatives to Clearbit for Data Enrichment: 5 Routes

The practical alternatives to Clearbit for data enrichment fall into five routes: a pay-per-call company API, enrichment built into your CRM, a contact-focused database, a bulk record vendor, and a do-it-yourself pipeline. Pick by the job you need done, then test each candidate on your own domains.

First, decide what “enrichment” meant for you

Clearbit enrichment covered several different outputs, and replacements rarely match all of them. Write down which fields your code or your routing rules actually read. For many teams the real list is short: company name, industry, employee band and country. Teams that used technographics, funding or revenue fields need a different shortlist from those who only needed a firmographic basics.

This is also why the question “what is the best alternative” has no single answer. As BusinessMCP’s Clearbit API alternative comparison puts it, Clearbit was folded into HubSpot as Breeze Intelligence, and enrichment is now described as a feature of paid HubSpot subscriptions rather than a standalone API. The same page reports that a September 2026 teardown found no new self-serve Clearbit API signups. Existing contracts reportedly still run, but no end date is published.

The five routes

Route	Example approach	Good for	Watch out for
Pay-per-call company API	Domain in, firmographics out, billed per hit	Developers, irregular volume, prototypes	Narrow field list
CRM-native enrichment	HubSpot Breeze Intelligence	Teams already on HubSpot	Not sold separately; not an external API
Contact database	ZoomInfo, Apollo	Sales teams needing people data	Seats, contracts, credits
Bulk record vendor	Coresignal-style datasets	Analytics, large batch loads	Monthly plans, per-record cost
DIY pipeline	Registry and web data you assemble	Unique requirements	Engineering time and upkeep

Route 1: pay-per-call company APIs

This is the closest drop-in for developers. You send a domain, you get a company record. BusinessMCP’s company data API is one example. Its company_lookup accepts a domain, URL or work email and, per the comparison page, returns name, industry, employee range, founding year, location with an ISO-2 country, company phone, LinkedIn page, a short description and website status. Price is $0.02 per company, charged only when found, and misses return found=false instead of a guess.

The limits matter as much as the features. The page states there is no name-to-domain lookup, no on-demand crawling, and no technographics, revenue, funding or intent fields. If any of those were in your Clearbit payload, you have a gap.

Route 2: CRM-native enrichment

If your sales process lives in HubSpot, Breeze enrichment is the path of least resistance. The comparison page says it is included in paid Marketing, Sales, Service, Data and Content Hub subscriptions and, for standard enrichment, does not consume HubSpot Credits. That makes it the better choice for HubSpot shops, and the page says so itself. The trade-off: it is not sold separately, so the effective cost is the seat, and HubSpot’s knowledge base documents no enrichment API.

Route 3: contact databases

ZoomInfo and Apollo are built around people and direct contact data, with intent signals in ZoomInfo’s case. Per the BusinessMCP comparison table (prices checked late September to early October 2026), ZoomInfo’s credits were about $0.38 each at the $1,000 tier and Apollo seats ran $49 to $119 per month on annual billing. They solve a different problem from firmographic enrichment. Read the side-by-side on ZoomInfo and Apollo before treating them as like for like.

Route 4 and 5: bulk vendors and DIY

Bulk record vendors suit analysts who want large datasets, and the same comparison lists entry plans from $49 a month. A DIY pipeline gives control but costs engineering hours; it rarely beats buying unless you have unusual sources.

Key takeaway: choose the route from the fields you actually use, not from the vendor with the longest feature list. A narrow API that returns exactly your four fields beats a platform you pay seats for.

How to compare candidates fairly

Use the same sample for every vendor so the numbers are comparable.

1. Export 200 to 500 domains from your CRM, mixing large companies, small ones and a few you know are obscure.
2. Run each candidate and record three things: how often it returns a record, how many returned fields are correct when you spot-check by hand, and what each hit cost.
3. Compute cost per correct record rather than cost per call. A cheaper call with a worse hit rate can cost more overall.
4. Check what a miss costs. BusinessMCP states misses are not charged; other vendors differ, and the price page is the place to confirm.
5. Look at freshness. Ask how often records are refreshed and whether a last-measured date is exposed.

The checklist for choosing an enrichment API expands this into a scorecard. If you already have code calling Clearbit, the migration guide covers field mapping and the order to cut over.

Where free options fit

You can run the whole sample test for little or nothing. BusinessMCP gives new accounts $5 of free credit for 7 days, once, which at $0.02 per found company covers a few hundred lookups if your hit rate is decent. Other vendors in the comparison offer small free tiers, for example Hunter with 50 credits a month. Our free alternatives roundup lists what each free tier does and does not cover.

A realistic recommendation

If you are a developer who needs firmographics by domain and does not use HubSpot, shortlist a pay-per-call API and one bulk or contact vendor, run the sample test, and decide on cost per correct record. If you are on HubSpot, confirm what your tier includes before buying anything. If you depended on funding, revenue or technographic fields, plan for a second source, since the narrow APIs say plainly they do not carry them.

Whatever you pick, keep the vendor call behind a small internal function. The reason you are reading this is that a data vendor changed its terms. Making the next swap a one-file change is the cheapest insurance you can buy.

Practical edge cases that break enrichment

Even a good provider fails in predictable places, and knowing them in advance saves a week of confusion after launch.

• Free-mail domains. Addresses at consumer mailbox providers carry no company information. Filter them before you call any API, or you will pay in time and sometimes in money for guaranteed misses.
• Subsidiaries and brands. A visitor from a regional subsidiary may resolve to the parent, or not at all. Decide whether your CRM wants the parent or the local entity, and write that rule down.
• Platform domains. BusinessMCP’s comparison page notes that brand platforms such as google.com return a name only. Any provider will behave oddly on domains that host other people’s content.
• Redirecting or offline sites. A domain that no longer responds is often a closed or acquired business. Some providers expose website status with a last-measured date, which is useful for filtering dead leads, and BusinessMCP’s company search excludes offline websites by design.
• Taxonomy drift. Industry labels differ between vendors. Normalise them into your own values so a vendor swap does not silently break routing rules.

Treat these as test cases in your sample. Include a dozen domains of each kind and see how each candidate behaves. The result will say more about operational fit than any feature list.

Where to try a lookup before committing

You can sanity-check a handful of companies without writing code. BusinessMCP offers a free company lookup tool for single domains, which is a quick way to see what fields come back and how a miss is shown. It is no substitute for a 300-domain sample, but it tells you in two minutes whether the output shape matches what your CRM expects.

If the shape fits, move to the scripted test described above, then use the pricing breakdown to turn your measured hit rate into a monthly budget. Keep the vendor behind a wrapper; of all the advice in this guide, that is the piece that pays off most reliably when the market moves again.
