Clearbit vs ZoomInfo
Clearbit
No longer sold on its own, now HubSpot data enrichment $20/ZoomInfo
Enterprise depth, now with a self-serve API $0.38/Clearbit vs ZoomInfo used to be inbound enrichment against outbound intelligence, and it still is, except Clearbit now lives inside HubSpot as data enrichment and comes with paid HubSpot seats on Starter and up. Pick Clearbit if you are on HubSpot and the job is enriching and routing inbound leads with company data. Pick ZoomInfo if the job is outbound: mobiles, org charts, budgets and intent on large accounts, delivered into whichever CRM you run. HubSpot's enrichment uses no credits and costs the seat, while ZoomInfo's self-serve route charges $0.38 a newly enriched record, so both can be forecast from a web page, on different bases.

Pick each one when
Clearbit
- You run HubSpot and the enriched records stay there.
- Inbound is the motion: scoring and routing form fills and website visitors.
- Enrichment priced into a seat suits you better than an annual package.
ZoomInfo
- Outbound is the motion and you need mobiles and direct contacts.
- Org charts, department budgets and hierarchy on enterprise accounts are the point.
- Your CRM is Salesforce or anything else that is not HubSpot.
Neither vendor publishes a match rate you could hold them to, so the rate card only tells you half the story. Take 500 rows from the segment you actually sell into, run them through one free tier and a small paid top-up on the other, verify both result sets, and divide spend by survivors. Half a day and about $20, and on a close pair it changes the answer often enough to be worth it.
What each one costs, tier by tier
Both publish a full rate card, so this comparison runs on numbers rather than on adjectives. Clearbit lists 3 tiers and ZoomInfo lists 3. Every figure is read off the vendor's own pricing page, and the pages they came from are listed at the foot of this one.
| The short version | Clearbit | ZoomInfo |
|---|---|---|
| Cheapest paid plan with the API | Starter, $20 | Pay as you go, $0.38/data credit |
| Tiers published | 3 | 3 |
| Free tier | Not sold standalone. Requires a paid HubSpot seat. | 1,000 data and 1,000 AI credits at signup, no card. Credits expire after 12 months. |
| Unit cost at entry | Not sold by the unit | $0.38 per data credit |
The cheapest paid plan is rarely the plan you end up on, because what moves you up a tier is usually volume rather than a feature. The two rate cards below are what you are choosing between.

What Clearbit and ZoomInfo cost at your volume
Put your own volume in. The model picks the cheapest published plan that covers it on each side, which is the question a rate card cannot answer and the one that decides the bill.
Clearbit
Priced per seat, so the bill moves with headcount rather than with volume.
ZoomInfo
Priced on the volume you use, so the plan that covers a normal month is the one that decides the bill.
Plans are read from each vendor's own pricing page and the model picks the cheapest one that covers you, so these are list prices on the billing term each vendor publishes, annual where that is how it prices, before any discount you negotiate.
What a year costs at three volumes
The same plan-fit arithmetic as the model above, run out to a year, because an annual number is what a budget actually asks for.
Clearbit is priced per seat, so that column does not move with volume. The figure shown is 3 seats for a year.
| A year at | Clearbit | ZoomInfo |
|---|---|---|
| 1,000 a month | $720 Starter | $4,560 Pay as you go |
| 10,000 a month | $720 Starter | $45,600 Pay as you go |
| 50,000 a month | $720 Starter | $228,000 Pay as you go |
These are list prices on the published plan that covers each volume, on the billing term each vendor publishes, so they are the number before you negotiate.
How this plays out once it is running
Clearbit's own site now reads "Clearbit has joined HubSpot!" and offers a customer login rather than a signup. What it advertised is still the inbound kit: company enrichment with 6-digit NAICS, GICS and SIC codes, corporate hierarchies, normalized role and seniority, IP intelligence to reveal the companies visiting your site, and form shortening. Inside HubSpot it is now data enrichment, included with paid seats on Starter and up, and HubSpot says it consumes no HubSpot Credits.
ZoomInfo is the outbound database, sold as quoted packages of licenses, credits and features, and since GTM AI also as a self-serve API at $0.38 a data credit after 1,000 free. A credit is spent per newly enriched record, through the app, the Chrome extension or the API, and the pricing page says what a credit costs depends on the depth of data in the package. Its Marketing Demand and ABM Enterprise packages list 75,000 and 150,000 included credits, and its Copilot tiers add intent, website visitors, champion tracking and job posting changes on top of the contact data.
What each one is genuinely good at
These are the things that keep somebody paying after the first month, which is a different question from what the marketing page leads with.
Clearbit
Built for inbound, inside the CRM
For a HubSpot team, HubSpot data enrichment fills contacts and companies where the workflows already run, with no second contract, key or sync. Routing a form fill by industry code, company size and seniority is the use case Clearbit was designed around.
No per-record meter
HubSpot says data enrichment does not consume HubSpot Credits, so enriching inbound records costs the seat and nothing per row. A ZoomInfo package is an annual forecast of credits; a seat price is a smaller and more forgiving commitment for uneven inbound volume.
The CRM API around it is free
HubSpot's CRM API is included on the free tier at 100 requests per 10 seconds, with two official MCP servers. Whatever you do with the enriched records afterwards, reading and writing them costs nothing extra.
ZoomInfo
Contacts and mobiles at depth
ZoomInfo Professional carries mobile numbers and business email alongside contact and company profiles, and its richer credits add technographics, department budgets and org charts. Clearbit's data here has no mobile numbers at all, so a calling motion only has one option on this page.
It works with whichever CRM you run
CRM integrations include HubSpot and Salesforce, and Copilot Advanced exports emails to Outreach or Salesloft. HubSpot data enrichment fills HubSpot records only, so a Salesforce shop has no route to it.
The signal layer is part of the product
Copilot Advanced adds buyer intent signals, website visitors, champion tracking and job posting changes, and Copilot Enterprise adds real-time and custom intent. For outbound teams that prioritize accounts by signal, that is a single contract rather than a stack.
Where each one falls down
Every provider on this site has a case it handles badly, and the people who find out are the ones who bought it for that case. These are the ones worth knowing before you sign rather than after.
Clearbit
Not sold on its own, and HubSpot only
There is no standalone Clearbit contract for new buyers, and access requires a paid HubSpot seat on Starter and up. The HubSpot developer reference page for the enrichment returned a 404 when this directory fetched it, noting that API reference content had moved. If your records live anywhere but HubSpot, this side of the page is closed.
You cannot buy the enrichment without the seats
Enrichment uses no HubSpot Credits and comes with paid seats on Starter and up, so it cannot be bought for records or for a pipeline on their own. The credit-metered part is intent, at 10 HubSpot Credits a company a month.
No mobiles and no MCP server
Work email, firmographics, technographics and intent, and nothing to dial. There is no MCP server for the enrichment either, so an agent reaches it only through HubSpot's own tools.
ZoomInfo
The packages are still a quote
Every enterprise package is a quote built from licenses, credit usage and features, and the self-serve route that publishes $0.38 a data credit sells no mobile numbers. The throughput is published, 5 requests a second on self-serve and up to 35 on the packages, but the price of the dialable row is still learned after a sales process.
Credit prices vary by package, and integrations need a minimum
Richer records cost more credits than basic firmographics, so an allowance does not translate into a row count until you map your fields. Pre-packaged integrations typically carry a base cost and a minimum bulk credit purchase on installation.
The API reference reads as legacy
Integration is REST against an API reference titled "ZoomInfo API - Legacy" on the page this directory read, so check which endpoints are current before building. ZoomInfo also runs an MCP server at mcp.zoominfo.com/mcp, which is the shorter route for an agent.
Using Clearbit and ZoomInfo together
Teams comparing these two often end up running both, and the arrangement below is the one they settle on.
This pairing is common in HubSpot shops and it is a split by direction rather than a duplication. HubSpot data enrichment covers inbound: form fills and website visitors scored and routed by company fields. ZoomInfo feeds outbound: lists of named accounts with mobiles, org charts and intent, synced into HubSpot through its integration.
The cost to watch is the same record enriched twice. A ZoomInfo export into HubSpot spends a ZoomInfo credit, and HubSpot's enrichment then fills the same fields again, so two sources can disagree on one record. Decide which system owns which properties, and keep HubSpot's enrichment on company fields for inbound records only.
Outside HubSpot there is nothing to combine, because Clearbit is not sold on its own. A Salesforce team reading this page is really choosing between ZoomInfo and the standalone enrichment APIs in this directory, and the deciding number is a match rate measured on its own list.
Clearbit or ZoomInfo, for you
Five questions, answered from the same records as the rest of this page. Nothing is sent anywhere and there is no result to email yourself.
Each answer leans one way. The recommendation appears here once you have picked at least two.
A tool like this can only weigh what is on the page. It does not know your workload, and the one test that does is the bake-off on this page: your own rows, queries or records, run on the cheapest entry each side offers.
Where an answer leans on a certification or an integration, it means that vendor publishes it on the pages this directory read, which is not the same as the other one lacking it. The sources are listed at the foot of the page.
Where the data comes from, and what you may do with it
The question that arrives late and expensively is who is allowed to hold the data. These are the fields each one returns, the coverage it claims and the compliance it publishes.
| Provider | Fields returned | Coverage | Compliance | Redistribution |
|---|---|---|---|---|
| Clearbit | Firmographics, Technographics, Intent and news | Global | GDPR DPA SOC 2 Type II CCPA | Not stated |
| ZoomInfo | Work email, Mobile phone, Firmographics, Technographics, Intent and news, Job changes | Strongest in NA | GDPR DPA CCPA | Not stated |
None of these states a redistribution position on its pricing or docs pages. Internally that never matters. Put the rows in something your customers can see and it becomes the question your legal team asks first.
Two practical notes that apply to every provider on this page. A compliance badge describes the vendor rather than your use of it, so a GDPR DPA does not give you a lawful basis for the outreach you send. And every one of these vendors runs its own opt-out, which means a person who asks you to delete their record has to be removed from your copy as well as from theirs.
Moving between Clearbit and ZoomInfo
Most readers of this page are already on one of these two, and the order below catches the expensive mistakes while they are still free.
Measure the thing you are about to lose
Run 500 rows you already have through Clearbit and record the match rate, the fields that came back populated and the cost. Without that number a migration cannot be judged, because every provider looks cheaper per unit than the one you are paying for today.
Check which fields change
ZoomInfo returns every field Clearbit does, so nothing downstream has to change shape. Confirm the values rather than the keys: two providers can both return a mobile number and disagree about which one it is.
Rewrite the auth and the limits, in that order
Clearbit works through HubSpot, not a standalone Clearbit key. ZoomInfo uses OAuth 2.0: client credentials for server-to-server, or authorization code with PKCE.
The limits are the part that bites later. Clearbit's limits: no separate meter: enrichment runs on paid HubSpot seats and uses no credits. Intent signals spend HubSpot Credits, which reset monthly.
ZoomInfo's limits: Self-serve 5 requests a second; packages 5, 25 or 35, with hourly and daily caps. A loop tuned to the first will either crawl or get throttled on the second.
Run both for one billing cycle
Keep the old key live and route a slice of real traffic to the new one. A month is the shortest honest test, because credit expiry, rollover and the overage rate only show up at renewal and those are where the surprises live.
Cancel on the renewal date
Credits on most of these plans do not survive a downgrade. Check what happens to the balance you have already paid for, and time the switch so you are not buying the same records twice.
The step people skip is the first one, and it is the only one that cannot be done after the fact. Once the old key is off you have nothing to compare the new match rate against, so a provider that is quietly worse on your segment looks like a provider that is fine.
The wider field for both
Sometimes the answer is neither, and the reason you are comparing these two points somewhere else entirely: Clearbit alternatives and ZoomInfo alternatives both start from the reason people leave.

4Nobody leaves ZoomInfo because the data is bad. They leave because the packages are annual and quoted, and the self-serve route that now exists costs $0.38 a record.
