Apollo.io vs Clearbit: Cross-Category Comparison

Clearbit's homepage now opens with a single notice: "Clearbit has joined HubSpot! The best B2B data provider is now part of the best B2B customer platform!" Its pricing address redirects to that homepage, and no plan is listed there. So Clearbit vs Apollo is no longer a contest between two products you can buy. Apollo still sells plans starting from a free tier at $0, while Clearbit's jobs (enriching records, scoring and routing leads, identifying website visitors and shortening forms) now have to be found somewhere else.

That makes the page worth reading for a different reason. Plenty of teams still carry a Clearbit line in a stack diagram, a CRM field mapping or a renewal calendar, and the question is what replaces the capability rather than which product wins a feature comparison.

Clearbit vs Apollo: Which One Should You Choose Today?

Choose by where your CRM lives, because Clearbit cannot be bought on its own any more. A team on one of the paid HubSpot subscriptions its help centre lists gets data enrichment inside HubSpot, and that help article states that data enrichment does not consume HubSpot Credits. A team on another CRM uses Apollo, whose paid plans start at $49 per seat per month billed annually and list CSV, CRM and API data enrichment.

The rest of this page is the detail behind that answer: which Clearbit job maps to which HubSpot feature or Apollo plan line, what Apollo charges for the inbound half, and which fields to audit before anything is switched off.

Why Compare These Two Tools?

Data enrichment tools provide the contact data that sales engagement platforms use for outreach sequences. The question for buyers is often whether an all-in-one platform that includes data can replace a dedicated enrichment tool.

Apollo.io is a sales engagement platform with its own contact data. Its site describes the database as 240M contacts and 30M companies, and its plan cards bundle sequences, a dialer, CRM integrations and data enrichment under one credit pool per seat.

Clearbit was a data enrichment tool for B2B lead, contact and account data. Its homepage still describes the capability, from enriching every record to scoring and routing leads in real time, IP intelligence for visitor identification and dynamic form shortening, and it now states that Clearbit has joined HubSpot.

Clearbit's job was record enrichment rather than list building. It filled in firmographics on a lead that already existed, scored and routed it, identified anonymous website traffic and normalised job titles into a consistent set of roles and seniorities. That is a marketing operations shape, which is why it usually sat behind a form rather than in front of a prospecting list. HubSpot now documents a data enrichment feature of its own, so a team on HubSpot looks there first, and a team not on HubSpot has to find the shape somewhere else.

Where Each Tool Fits in Your Workflow

What Each Side Actually Does in a Cold Outbound Run

Apollo.io covers more of this run than one category label suggests. The same seat that sends the sequence also searches the database, reveals a contact and enriches a CRM record, and Apollo's pricing page meters all of it from one credit pool per seat. So the useful question on this page is not which product sends the email. It is whether Apollo's own data holds up on the accounts that matter, and where Clearbit earns a second line on the invoice.

The run itself still has a fixed shape. Build the list, resolve and verify a mailbox for every person on it, then send. RevenueFlow runs one message per campaign, so there are no bump steps and no thread replies scheduled behind the first send. A prospect who does not answer gets re-approached later in a new campaign with a different angle, never with a second message stacked under the one they ignored, and on LinkedIn that second message does not get sent at all.

Reading the reply and booking the meeting sit outside both products. A meeting counts when it matches criteria agreed in writing before launch, which is a commercial decision rather than a feature, and it is the number worth measuring either purchase against.

Pricing Comparison

Apollo.io Pricing

Prices are per seat per month. The page marks annual billing as a 24% saving and labels the whole ladder introductory pricing that may change, so read it again before a renewal.

Clearbit Pricing

Clearbit's homepage lists no price. Its pricing address redirects to the homepage, which opens with the notice that Clearbit has joined HubSpot and lists no plan. A Clearbit tier price found anywhere else describes a ladder that is no longer sold, so it is a historical record rather than a quote, and this page does not print one.

For a HubSpot team the cost question moves to HubSpot. Its data enrichment help article lists the feature on the Starter, Professional and Enterprise editions of its Marketing, Sales, Service, Data and Content hubs. It also states that data enrichment does not consume HubSpot Credits, while smart properties do.

Reading the Two Price Shapes Together

One side of this comparison has a price list and the other has none. Apollo publishes $49, $79 and $119 per seat per month billed annually, $65 and $99 on monthly billing for Basic and Professional, and sells Organization on annual billing only with a three seat minimum. Clearbit has no current standalone purchase path and no price to re-check, so the only live cost comparison is Apollo's plans against whatever HubSpot subscription a team already holds.

What One Year of This Stack Actually Costs

The costing that matters here is a replacement costing rather than a comparison. The team below is invented for the example and the prices are the ones Apollo's pricing page shows, so every total in this section is illustrative.

A three person revenue team on Apollo Basic pays $49 per seat per month billed annually, so $147 a month and $1,764 for the year, carrying 30,000 credits per seat per year granted upfront. On monthly billing the same card shows $65 per seat and 2,500 credits per seat per month. That covers prospecting, enrichment and sending in one line.

The Clearbit-shaped work is the part to price separately, and it splits in two. Inbound enrichment, where a form fill needs to become a scored and routed record, now lives inside HubSpot for teams already there, and HubSpot's help article says data enrichment does not consume HubSpot Credits. Outbound enrichment, where a list of companies needs contacts attached, is what Apollo's own credits cover, and 30,000 credits a seat a year is a large allowance against most outbound volumes.

The residual is visitor identification and form enrichment for a team that is not on HubSpot. Apollo's Basic, Professional and Organization cards each list website visitors with 100 companies identified monthly, and the Free card lists 20. The Inbound add-on, at $119 per team per month billed annually, raises that to up to 50,000 companies a month and enriches 5,000 form contacts a month, with credit usage applying. Adding it to the illustrative team puts the year at $1,764 plus $1,428, or $3,192.

Clearbit's Jobs, Mapped to HubSpot and Apollo

Clearbit's homepage still lists what it was bought for: enriching every lead, contact and account record, scoring and routing leads in real time, IP intelligence that reveals which companies visit a site, dynamic form shortening, and granular industry data including 6 digit NAICS, GICS and SIC codes, corporate hierarchies and a normalized role and seniority set.

On HubSpot, the data enrichment help article covers most of that list. Records can be enriched automatically and continuously, one at a time, or in bulk. Enriched fields improve lead scoring and can trigger workflow enrollment, the Intelligence tab shows website visitor activity, and form shortening checks the enrichment dataset and only displays the fields that cannot be enriched. Contact enrichment matches on first name, last name and work email address, and company enrichment on the company domain.

On Apollo, the same jobs are plan card lines. Basic and Professional list CSV, CRM and API data enrichment, AI lead scoring, 3 inbound routers, real-time form enrichment with a 10 limit and website visitors identified at 100 companies a month. The Inbound add-on raises visitor identification to up to 50,000 companies a month and enriches 5,000 form contacts a month.

Clearbit job	On HubSpot	On Apollo
Enrich every record	Automatic, continuous, individual or bulk enrichment	CSV, CRM and API data enrichment on Basic and Professional
Score and route	Enriched fields improve lead scoring and trigger workflow enrollment	AI lead scoring and 3 inbound routers
Reveal visiting companies	The Intelligence tab shows website visitor activity	100 companies a month; up to 50,000 with the Inbound add-on
Form shortening	Only the fields that cannot be enriched are displayed	Real-time form enrichment, 10 limit; 5,000 form contacts a month with the add-on
NAICS codes, hierarchies, role and seniority	Check the property list field by field	Check field by field

What Does Not Transfer Cleanly

What does not transfer cleanly is the depth of the firmographic normalisation Clearbit was bought for: six digit industry codes, corporate hierarchies, a standardised role and seniority set. A team that built routing rules on those fields should check field by field rather than assume the replacement is like for like.

Integration Ecosystem

Apollo.io Integrations

Apollo's pricing page lists CRM integrations with Salesforce, HubSpot and Pipedrive, an Outreach and Salesloft integration, SendGrid and Mailgun, workflow integrations, and LLM integrations through MCP.

Where Clearbit's Data Flows Now

Clearbit's homepage no longer lists integrations. Inside HubSpot, the data enrichment help article lists what enriched fields feed: form shortening, lead scoring, segmentation on fields such as job title, industry and company size, personalization tokens in emails and pages, and workflow enrollment. Any non-HubSpot connection that used to carry Clearbit fields is the first one to check field by field.

When to Choose Which

Read the tree as a question about where your records live rather than about which product is better. The first branch settles most cases, because a HubSpot team already has an enrichment feature to switch on and audit, while everyone else is replacing a capability rather than renewing one.

Do You Need Both, and in Which Order?

Not a both. This is a migration question with two branches.

If the CRM is HubSpot, turn on data enrichment first. HubSpot's help article says automatic enrichment settings are turned off by default and a customer action is required to turn them on, for contacts and companies separately. Then confirm the specific fields the old routing rules depended on still arrive with the same names and the same normalisation. That check is the whole project, and it is worth doing before a renewal rather than after a routing rule silently starts matching nothing.

If the CRM is not HubSpot, the enrichment shape has to be rebuilt. Apollo covers the outbound half through its own credits and its form and CRM enrichment, and the inbound scoring and routing half is the part to scope deliberately. Either way, treat a stack diagram that still shows Clearbit as a standalone line as out of date, and treat a Clearbit price found on a third party page as a historical figure rather than a quote.

Using Both Together

Using both now means one specific stack: Apollo sending outbound while HubSpot enriches the inbound records. Apollo's Basic card lists CRM integrations and its plan comparison names HubSpot among them, so the two meet at the CRM record, and the thing to settle in advance is which system may write which field. HubSpot's help article says existing data is kept unless you choose to overwrite it during manual enrichment, or turn on the setting that overwrites incorrect enrichment values.

Rolling It Out Without Breaking the Run

Audit before replacing. List every field a Clearbit deployment writes and every rule that reads one, because the expensive failure here is a routing rule that keeps running against a field nothing fills any more.

Whichever order the two arrive in, keep the sending inventory out of it. Sender domains, mailbox warmup and daily caps are their own project, and a stack change made in the same week as a sending change leaves nothing to attribute a bounce rate to. Change one layer, let a full wave run, then change the next.

Two more habits save real money. Run the trial on accounts already worked rather than on a fresh list, because the only coverage question that matters is coverage on the segment being sold to, and a vendor's own sample is chosen to look good. And export what the incumbent already found before any subscription lapses: contact records bought once are cheap to keep and expensive to buy twice.

Decision Framework

1. Name the gap before naming a tool. Write down which stage is actually costing meetings: a list that runs out, addresses that bounce, or messages that never go out on time. A stack decision made without that sentence is a preference.
2. Price the whole year, not the entry tier. Seat minimums, annual billing and per-credit top-ups move the real number more than the headline price does.
3. Measure at the pipeline, not per tool. Both products feed one funnel, so the honest measure is meetings booked against criteria fixed in advance, read before and after the change.

The Short Version

On HubSpot: switch on data enrichment, verify the fields and close the standalone line. Not on HubSpot, and the need is outbound contacts: Apollo credits cover it. Not on HubSpot, and the need is inbound scoring and routing: that is a separate scope, and Apollo's form and CRM enrichment is where to start measuring the gap.
