Apollo.io vs Clay

Both are go-to-market platforms for B2B prospecting, but Apollo.io bundles its own contact database with built-in outreach, while Clay focuses on waterfall enrichment across 150+ providers and AI research automation.

Quick answer: Apollo.io is the better choice for b2B sales and revenue teams, especially startups and small-to-midsize companies, that want database, enrichment, and outreach in one affordable platform.; Clay is the better choice for revOps, marketing, and outbound teams running high-volume GTM that need broad data coverage and AI research automation in a flexible workspace..

The verdict

Pick Apollo.io if you want a database, enrichment, and outreach in one affordable package. It pairs a large B2B contact and company database with advanced filters, verified email and phone enrichment, and multi-channel sequences across email, calls, and LinkedIn. With a free plan, a 14-day trial, and paid tiers from a low entry price, it is the simpler, cheaper starting point for sales development and revenue teams running outbound without stitching tools together. The trade-offs are data accuracy that can vary by region and industry, and credit limits that get restrictive on lower tiers.

Pick Clay if you want maximum data coverage and AI-driven automation. Its waterfall enrichment queries 150+ premium providers in sequence to maximize match rates, and Claygent AI agents handle custom research at scale inside a flexible, spreadsheet-style workspace with conditional logic and a natural-language builder. It includes a native email sequencer, ad syncing to LinkedIn, Meta, and Google, two-way Salesforce and HubSpot sync, plus webhooks and an HTTP API. Expect a steeper learning curve and credit-and-action pricing that is harder to predict, so it pays off most for teams running serious GTM volume. Many teams pair the two: Apollo as the all-in-one base, Clay as the enrichment and automation layer.

Rating	4.5	4.6

Pricing compared

Both are freemium with a permanent free plan and a 14-day trial, but they sit at very different price points. Apollo.io starts at $49/mo per user, with Basic, Professional, and Organization tiers billed per user per month and an annual discount, plus a free plan with limited monthly credits. Clay starts higher, around $185/mo, layering a credit-and-action model on top of monthly plans so costs scale with how much data you pull and how many workflow steps you run, with custom Enterprise pricing above that. Apollo.io is the cheaper and more predictable entry point; Clay's usage-based model needs planning and suits higher-volume teams.

Features compared

Apollo.io centers on its own B2B contact database with advanced filters, data enrichment for verified emails and phone numbers, multi-channel sequences with A/B testing and analytics, lead scoring and buying signals, AI writing assistance, and CRM integrations. Clay centers on waterfall enrichment across 150+ data providers, Claygent AI research agents, intent signals such as job changes and hiring activity, spreadsheet-style workflow automation with conditional logic, a native email sequencer, and two-way Salesforce/HubSpot sync plus webhooks and an HTTP API. Apollo is the more self-contained all-in-one prospecting and outreach tool; Clay trades that bundling for deeper enrichment coverage and programmable AI automation.
