Clearbit vs Apollo: a side-by-side comparison

Two products that solved adjacent problems and now live in different worlds

Clearbit and Apollo were once direct competitors — both pulled firmographic and contact data from the same broad pool of public sources. The HubSpot acquisition in November 2023 changed that. Clearbit became Breeze Intelligence, a HubSpot-only enrichment layer; the standalone API was deprecated April 30, 2025. Apollo continued as an independent platform and expanded into the sales engagement space (sequences, dialer, AI assistance). Today they overlap on data enrichment but solve fundamentally different jobs.

Side-by-side comparison

The fastest scan of where the two products sit. Pricing, deployment time, and integration depth often shape the decision before any feature comparison matters.

Four scenarios where Clearbit (Breeze Intelligence) fits well

Clearbit is no longer evaluated as a standalone product — it's evaluated as a HubSpot capability. The scenarios where it fits all share one common thread: HubSpot is already your committed CRM or you're actively committing to it.

• You're already on HubSpot Professional or Enterprise
  If your CRM, marketing automation, and sales engagement already live in HubSpot, native enrichment removes a vendor and a sync layer. Standard enrichment doesn't consume HubSpot Credits on paid plans, which means the practical cost is the platform you're already paying for. The integration is zero-configuration: visitor identification, form shortening, and CRM record enrichment work in the same workspace your team uses every day.
• Your motion is inbound-marketing-led with strong content and forms
  Form shortening (auto-filling fields based on returning visitor data) and IP Reveal (identifying anonymous companies visiting your site) are Clearbit's strongest features. They convert anonymous interest into structured leads inside the same system that handles your nurture sequences. For inbound-led B2B with marketing-qualified leads as the primary funnel input, this lives where the work happens.
• You need buyer intent integrated into existing HubSpot workflows
  Buyer intent signals (companies showing topic-related research activity) flow into HubSpot's lead-scoring and workflow automation natively. Sales gets prioritized accounts; marketing gets segmentation criteria for nurture; both operate from the same data foundation. Standalone intent platforms require integration work that Breeze Intelligence skips entirely.
• Your team has limited bandwidth for stack management
  Adding a separate enrichment vendor means contracts, security review, integration upkeep, and another tool for the team to learn. Breeze Intelligence collapses that overhead — one vendor relationship, one security review, one billing line. For lean RevOps teams that want fewer moving parts, the consolidation is the value.

Four scenarios where Apollo fits well

Apollo's positioning shifted significantly post-2023 from a pure data provider to a database-plus-engagement platform. The scenarios where it fits all share one thread: outbound sales motion with the database, sequencing, and dialer wanted in one workspace.

• You're running outbound prospecting with sequences and dialing
  Apollo combines the contact database with the engagement layer (email sequences, A/B testing, US and international dialers, call recording). For SDR teams running cold outbound, having contact reveal, sequence enrollment, and dialer in one workspace means fewer tab switches and tighter feedback loops between which contacts get added and which sequences they enter.
• You're on Salesforce, Pipedrive, or any non-HubSpot CRM
  After the Clearbit/Breeze transition, Apollo is one of the few enrichment-grade platforms that still works natively with non-HubSpot CRMs. Salesforce integration is mature; Pipedrive, Outreach, and Salesloft connections are supported; the REST API handles custom CRMs. If your stack is committed to Salesforce, Apollo is the closer comparison to historical Clearbit.
• Your team needs predictable per-seat pricing
  Apollo publishes its plan pricing publicly and bills per user per month. Budgeting for 8 SDRs at the Professional tier is straightforward arithmetic ($79 × 8 × 12 = $7,584 annually before credit overages). The transparency lets RevOps forecast spend without negotiating opaque enterprise contracts. Credit overages and mobile-credit caps still apply, but the per-seat baseline is predictable.
• You want a free tier to validate before committing
  Apollo's permanent free plan (900 credits annually, 2 sequences, basic search filters) is enough to test data quality on your specific ICP before paying. Most enterprise enrichment platforms require sales conversations and demos to access; Apollo lets a single SDR self-serve, validate, and decide whether to upgrade. The free tier reduces evaluation friction.

Five capability areas where the products differ

Both platforms enrich CRM records and reveal contact data — that's the overlap. The differences show up in what each platform does beyond the database layer. Here's how each handles the five capabilities most teams care about.

Actual cost at three customer sizes

Headline pricing rarely reflects actual cost at scale. Clearbit's $45/mo headline is technically accurate but excludes the required HubSpot subscription. Apollo's $49/user/month headline excludes credit overages and mobile credit costs. Here's what each tier actually runs at three customer sizes, with the assumptions stated.

Switching costs in both directions

Switching costs run in both directions and look very different depending on which way you're moving. Clearbit's HubSpot lock-in means leaving requires either a CRM migration or re-platforming the enrichment layer. Apollo's CRM-agnostic position means leaving primarily affects the engagement layer (sequences, dialer history) rather than core CRM data.

What neither platform handles well

Both platforms solve the data + workflow layer for B2B sales. Both have meaningful gaps where teams typically end up bolting on additional tools or building custom infrastructure. Acknowledging these gaps before signing changes which platform you actually choose.

Six questions to answer for yourself

Six questions worth answering before deciding. The right tool follows from the answers, not from the comparison table. Take ten minutes per question; the wrong tool here costs more than the time spent deciding.

1. 01
   Are you committed to HubSpot as your CRM?

   If yes, Clearbit (Breeze Intelligence) is the lower-friction path — same vendor, same workspace, same security review. If you're on Salesforce, Pipedrive, or another CRM, Clearbit is effectively unavailable; switching to HubSpot to get Clearbit is a multi-quarter project, not a tooling decision. The CRM commitment determines half the choice.
2. 02
   Is your motion inbound-led or outbound-led?

   Inbound-led teams (content, SEO, paid acquisition feeding form submissions) get more value from Clearbit's form shortening and visitor ID inside HubSpot. Outbound-led teams (cold email, dialer, multi-touch sequences) get more value from Apollo's combined database + engagement layer. Mixed-motion teams need to decide which side they're optimizing for first.
3. 03
   Do you need predictable per-seat pricing or are you comfortable with usage-based billing?

   Apollo bills per seat with credit caps and overage charges — predictable baseline, variable overage. Clearbit bills as HubSpot subscription + credits — the subscription is predictable, the credit consumption scales with AI feature usage and is harder to forecast. RevOps teams that need clean budget projections often prefer Apollo's structure.
4. 04
   What's the actual quality requirement for your contact data?

   Apollo's email accuracy of 65–70% and mobile accuracy of 30–75% is acceptable for high-volume outbound where you can verify before sending. For high-stakes outreach (ABM, executive outreach, regulated industries), you need either Cognism-tier human-verified data or waterfall enrichment across multiple providers. Neither Clearbit nor Apollo is the answer at the high-accuracy end.
5. 05
   How much engineering capacity do you have for integration work?

   Clearbit-on-HubSpot is zero-configuration if HubSpot is already deployed. Apollo's CRM integrations are mature but require configuration work for non-HubSpot CRMs (especially Salesforce custom objects, Pipedrive workflow rules, custom CRM REST APIs). Engineering-poor teams often default to whichever path requires the least integration debt.
6. 06
   What's your ICP geography?

   Both platforms skew North-American in their data coverage. For EMEA-focused teams, Cognism has stronger GDPR-compliant European data than either. For APAC, both platforms have meaningful coverage gaps. If 30%+ of your ICP is outside North America, neither Clearbit nor Apollo is the strongest answer — both can complement a region-specialized provider, but neither is the foundation for international ICP.
