Pricing

Apollo is the more accessible entry, with a free plan and paid plans from around $49/seat/mo that bundle the database, sequencing, and a dialer. Clay also has a free plan but paid plans start at around $167/mo billed annually, and its credit-based usage can be hard to predict because every enrichment provider you chain consumes credits. Apollo’s pricing is simpler to forecast; Clay’s cost scales with how ambitious your workflows get. Teams that just need cheaper European data sometimes pair either with Pipecorn for credit-based enrichment, but for most US-centric stacks this comes down to Clay versus Apollo.

Verdict: Apollo for predictable, lower entry pricing; Clay if its flexibility justifies the higher, usage-based cost.

Features

Apollo is all-in-one: a 275M+ contact database, sequencing, a dialer, intent data, and a strong Chrome extension, so you can go from find to outreach without leaving the app. Clay is a composable engine, chaining 100+ data providers in a waterfall to maximize hit rates, running AI research agents to enrich and score accounts, then pushing lists to your sequencer or CRM. Apollo gives you a database and a workflow out of the box; Clay gives you the building blocks to design your own.

Verdict: Apollo for a complete prospect-to-outreach workflow; Clay for bespoke, signal-based enrichment at scale.

Integrations

Clay leads on breadth that matters for data work, with around 120 integrations including HubSpot, Salesforce, Apollo, Smartlead, and OpenAI, and it can even use Apollo as one of its waterfall sources. Apollo has roughly 100 integrations across Salesforce, HubSpot, Gmail, Outreach, and Zapier. Clay is the better hub for assembling data from many places; Apollo is the better single source plus outreach engine.

Verdict: Clay for connecting many data sources; Apollo for a self-contained stack.

Ease of use

Apollo is intermediate but approachable, since the workflow is largely defined for you. Clay is advanced, with a real learning curve: the spreadsheet metaphor is powerful, but you assemble the logic yourself, and getting waterfalls and AI prompts right takes time. Teams with RevOps muscle love Clay; teams that want results on day one tend to prefer Apollo.

Verdict: Apollo for a faster ramp; Clay if you have the skills to exploit its depth.
