What is Apollo?

Apollo is an AI sales platform that unifies data, intelligence, and execution into one connected GTM system, built so B2B teams can find, engage, and convert their best-fit buyers without stitching together multiple tools. The platform spans prospecting, outbound sequencing, a built-in dialer, inbound routing, data enrichment, and AI-driven research, all drawing from a database of 240M+ people and 30M+ companies with 98% email accuracy.

Apollo meets sellers inside the tools they already use. Via Apollo MCP, Apollo's Model Context Protocol, teams can surface contact data and trigger workflows directly inside AI assistants like ChatGPT, Codex, Claude, and Perplexity. The Chrome extension brings prospecting across the web, and for technical users, Apollo CLI enables terminal-native access for headless GTM workflows and API-driven automation.

Adoption reflects this momentum. According to Ramp's vendor data, Apollo holds a 38% adoption rate among businesses using Sales Data Providers software, up 5 percentage points year-over-year as of July 2026, and captures 34% of all first-time buyers entering the category. Apollo is trusted by 100K+ paying customers and used by 100+ teams at Fortune 500 companies, and has earned the 2026 MarTech Breakthrough Award for "Best AI-Powered Sales Solution".

Apollo offers transparent pricing starting at $49/user/month (annual billing), with a free tier available for teams that want to test data quality before committing.

What is Clearbit?

Clearbit is a B2B data provider that gathers public web data and proprietary sources, applying AI and LLMs to convert unstructured information into standardized datasets. Clearbit was acquired by HubSpot in 2023, and its data enrichment capabilities are now integrated into HubSpot's platform. No standalone Clearbit pricing page is available as a result of the acquisition.

Clearbit's core offering centers on four areas: enriching contact and company records, identifying anonymous website visitors through IP intelligence, scoring and routing inbound leads, and optimizing web forms through dynamic field shortening. The platform provides industry categorization using 6-digit NAICS, GICS, and SIC codes, normalized role and seniority data, and corporate hierarchy mapping for parent companies and subsidiaries.

Clearbit's dataset claims global coverage across every country and language, with AI/LLM-based processing used to improve data accuracy and coverage. The platform targets B2B companies and go-to-market teams that need enriched, structured data flowing into their existing CRM and marketing stack, particularly HubSpot users following the acquisition.

Where Clearbit focuses on enriching and routing data, it does not include native outbound sequencing or a built-in dialer. Teams that need execution capabilities alongside enrichment would look to integrate Clearbit's data layer with separate engagement tools.

Feature Comparison

The clearest structural difference between the two platforms is execution: Apollo includes outbound sequencing, a dialer, and AI workflow automation as core features, while Clearbit's strength lies in enrichment, visitor identification, and routing, without a native engagement layer. For teams already invested in HubSpot, Clearbit's integration may be a natural fit.

For teams that want data and execution in one system, Apollo covers both.

Pricing Comparison

Apollo's pricing is publicly listed at apollo.io/pricing and structured around four tiers (all prices reflect annual billing):

• Free: $0, 900 credits/year, 2 sequences, basic filters
• Basic: $49/user/month, 30,000 credits/year, unlimited sequences, CRM integrations, 6 intent topics
• Professional: $79/user/month, 48,000 credits/year, US dialer, 5 mailboxes, automated workflows, AI research
• Organization: $119/user/month (min 3 users), 72,000 credits/year, international dialer, 15 mailboxes, SSO, advanced security

Clearbit's pricing is not publicly displayed. Following Clearbit's acquisition by HubSpot in 2023, its enrichment features are now bundled within HubSpot's platform, contact their sales team for pricing details relevant to your use case and existing HubSpot subscription.

The practical implication: Apollo allows teams to evaluate pricing, credits, and capabilities before any sales conversation. Teams can start on the free tier, validate data quality, and upgrade when ready.

Clearbit's pricing requires direct engagement with HubSpot's sales team to scope.

How Apollo Differs from Clearbit

The core difference is scope. Clearbit is a data enrichment and signal layer, it makes your existing records better and helps identify who is visiting your site.

Apollo is built to take action on that intelligence: find the right contacts, enrich records, run multi-channel outreach, make calls, track engagement, and improve over time, all within one connected system.

According to Ramp's Sales Data Providers category data, Apollo is the fastest-growing vendor in the category as of July 2026, averaging +0.7 percentage points of adoption per month, ahead of every other vendor tracked. Teams moving into the Sales Data Providers space are choosing Apollo at a rate that reflects its expanding platform capabilities, not just its data coverage.

Several practical differentiators stand out:

• Execution included: Apollo's sequences, Power Dialer, Parallel Dialer, and AI-driven workflows are built into the same platform as its data, no separate engagement tool required.
• Living Data Network: Apollo's contacts are continuously validated and refreshed, reducing the risk of stale records degrading campaign performance.
• Transparent, accessible pricing: Apollo's free tier and publicly listed plans let teams verify fit before committing to a contract.
• AI research and automation: Apollo's AI Research Agent, AI Sequence Builder, and automated lead scoring go beyond data delivery into active workflow automation.
• Platform flexibility: From the Chrome extension to Apollo MCP integrations with ChatGPT and Claude, to the Apollo CLI for technical builders, Apollo is designed to fit how modern GTM teams work.

As Collin Stewart, CEO at Predictable Revenue, put it:

"We reduced the complexity of three tools into one."

For teams evaluating Clearbit primarily as a HubSpot enrichment add-on, that use case remains straightforward. For teams that need prospecting, enrichment, engagement, and analytics without managing multiple vendor relationships, Apollo covers the full workflow.

Apollo and Clearbit overlap in data enrichment and website visitor identification, but Apollo covers significantly more of the GTM workflow, including outbound sequences, a built-in dialer, and AI-powered automation.
