Clearbit Enrichment API Alternative: What to Use in 2026

If you need a Clearbit enrichment API alternative, first check what you actually used. HubSpot absorbed Clearbit into Breeze Intelligence, and a September 2026 teardown reported no new self-serve API signups. HubSpot users may stay put; everyone else should compare firmographic APIs by fields, coverage and pricing.

What changed

Per BusinessMCP’s Clearbit alternative page, which is written by a competing vendor and should be read with that in mind, HubSpot bought Clearbit in late 2023 and folded it into HubSpot as Breeze Intelligence. It reports that the free Clearbit platform, weekly visitor report and Clearbit Connect ended on April 30, 2025, that the free Logo API was switched off on December 8, 2025, and that a September 2026 teardown found no new self-serve Clearbit API signups. It says existing contracts reportedly still run, but that no HubSpot page states how long. Confirm all of this with HubSpot directly before you plan around it.

Who has which options

If you…	Consider	Note
Already pay for HubSpot	Breeze Intelligence	Included in paid plans, per the page; no enrichment API documented
Need only firmographics by domain	A public-data API	Cheaper, thinner fields
Need contacts and people data	A commercial database	Seat or credit pricing
Need funding data	Crunchbase-type sources	Enterprise licensing, per the comparison page
Need IP-to-company	An IP data service	Company field tier matters

Key takeaway: the right Clearbit alternative depends on which Clearbit feature you used. Logo, enrichment, reveal and prospecting have different replacements.

One concrete alternative

The BusinessMCP Company Data API takes a domain, URL or work email. Its Clearbit-alternative page says company_lookup returns name, industry, employee range, founding year, location, phone, LinkedIn, a description and website status, and found=false for unknown domains. It is available over REST and MCP on one key, bulk lookup accepts up to 100 domains per call, and pricing is $5 free for 7 days then prepaid packs from $10, with $0.02 per found lookup.

Be clear about the gaps, which the page itself lists: no technographics, revenue, funding or intent data, no on-demand crawling, and no name-to-domain lookup. It also describes itself as a young product from a small company, which is relevant to risk. If you depended on Clearbit’s technology or revenue fields, this is not a like-for-like swap.

Migration steps

1. Inventory usage. Which endpoints and fields did you call, and how often?
2. Map fields. List each Clearbit field you used and whether the new source has it.
3. Run a parallel test. Resolve the same 300 domains with the old and new source and compare found rate and disagreements.
4. Decide for gaps. Drop the field, source it elsewhere or accept a worse proxy.
5. Wrap the vendor. Put one function between your code and any vendor so the next change is cheap.
6. Backfill gradually. Re-enrich only stale records, with a cache and a spend cap.
7. Keep dates and sources in your database to tell old-source from new-source values.

Our pieces on enrichment options and the provider comparison help with steps 2 and 3.

Cost comparison, carefully

Direct price comparison is hard, because the comparison page states that Clearbit/HubSpot has no separate published API price; enrichment is part of paid HubSpot plans. The page lists Sales Hub Starter at $20 per seat per month ($15 billed annually) with limited-time introductory prices reportedly lower, but that is a plan price, not an API price. A pay-per-hit API will usually look cheaper at low volume and different at high volume; model it using the formula in pricing.

What not to assume

• That any alternative carries the same fields.
• That prices stated by a competitor’s comparison page are current; vendors update plans.
• That a new tool’s hit rate matches your old one. Test.
• That your existing contract status is unchanged; ask your account owner.

Keeping your options open

Whichever route you take, design for the next change. Normalise vendor responses into your own schema, store source and date, and keep the migration test script. A one-afternoon parallel test is cheap insurance against the same surprise happening again.

A worked example of a parallel test

Suppose you used a Clearbit-style lookup mainly for three fields: company name, employee range and industry. Your test plan might look like this.

1. Export 400 domains from signups in the last year, 100 each from four size bands.
2. Run them through the candidate, for example the BusinessMCP Company Data API, and through whatever you still have access to.
3. For each field, count: both agree, they disagree, only one has a value, neither has a value.
4. Hand-check 25 of the disagreements against company websites to see which source was right.
5. Compute the cost of the candidate at your real volume using the listed $0.02 per found lookup.

The table at the end tells you whether the swap is acceptable for these three fields. It will not tell you about fields you did not test, which is why the first step, listing what you actually used, comes first.

Fields people forget they depended on

When teams migrate they discover hidden dependencies. Typical ones: a technology field that fed a segmentation rule, a revenue band that drove territory assignment, a logo URL embedded in an app, or a visitor-reveal feature wired into a dashboard. Each needs its own replacement or a conscious decision to drop it. The BusinessMCP page itself says it does not offer technographics, revenue, funding or intent data, so a team that relied on those would have to look to a commercial database or accept a gap.

If your dependency was IP-based identification of website visitors, that is a different product; BusinessMCP lists a separate IP data API for it, and you should evaluate it on its own page rather than assume it behaves like the company endpoints.

Questions for your current account owner

If you are still on a legacy contract, ask these in writing:

• What is the end date of my API access?
• Will pricing change at renewal?
• Is there a documented replacement endpoint?
• What data export is available if access ends?

The comparison page says it found no public statement of a cutoff for legacy keys, so the answer has to come from the vendor, not from a blog. Get it before you plan the cut-over date.

Decision summary

Stay with Breeze if you live in HubSpot and its included enrichment covers your fields. Choose a pay-per-hit firmographic API if you need an API, want predictable low-volume costs and can live without revenue and technology data. Choose a commercial database if you need people data or funding. Whatever you choose, wrap the vendor and keep the test script.
