Clay vs Apollo (2026) Compared
Apollo gives you one database and one workflow. Clay gives you 75+ databases and infinite flexibility. The right choice depends on your team's technical sophistication.
The Short Version
Apollo is the better choice for sales teams that want contact data + outreach in one simple platform at an accessible price. Clay wins for RevOps teams and technical users who want to waterfall across multiple data providers, build custom enrichment workflows, and maximize data coverage. The biggest risk with Apollo is accepting its data accuracy limitations; with Clay, it's overbuilding workflows your team can't maintain.

Deep Dive: Clay
What They're Selling
Clay is a data enrichment and research platform. Instead of relying on one database, you query 75+ data providers and use the best result for each contact. The waterfall approach typically improves coverage 20-40% over any single provider. Clay also lets you build custom AI research workflows that go beyond basic contact data.
What It Actually Costs
Plans start at $149/month for 1,500 credits. The Explorer plan ($349/mo, 5,000 credits) is where most teams land. Heavy users hit Pro ($800/mo, 25,000 credits). Each enrichment action costs credits, so costs scale with volume and complexity. A 10-person team doing serious enrichment: $400-$1,200/month.
What Users Say
RevOps teams and growth hackers love it. They describe it as a 'spreadsheet on steroids.' Traditional sales reps find it intimidating. The learning curve is real but the payoff in data quality is significant for teams that invest the time.
Pros
- 75+ data sources means best-in-class coverage
- Custom AI workflows for deep prospect research
- Waterfall enrichment improves match rates 20-40%
- Flexible enough for any data workflow
Cons
- Steeper learning curve than traditional tools
- Credit-based pricing requires careful management
- No built-in outreach features
- Can get expensive with complex, high-volume workflows
Deep Dive: Apollo.io
What They're Selling
Apollo is the all-in-one sales platform: 275M+ contacts, email sequences, phone dialer, LinkedIn integration, and basic CRM. For teams that want one tool to handle prospecting through outreach, Apollo delivers at an aggressive price point.
What It Actually Costs
Free tier gives you 250 emails/day. Basic ($49/user/mo) is enough for most SMBs. Professional ($79/user/mo) adds advanced filters and integrations. A 10-person team on Professional: ~$9,500/year. That's less than Clay alone for most use cases.
What Users Say
Sales teams appreciate the simplicity: find a contact, add to sequence, done. The main complaints are data accuracy (particularly on phone numbers and less common industries) and occasional outdated contacts. It's 'good enough' data at a great price.
Pros
- Free tier with real functionality
- All-in-one: data + email + dialer in one tool
- 275M+ contacts with decent accuracy
- Much simpler to learn and use than Clay
Cons
- Single database limits data coverage
- Email accuracy (80-85%) lower than ZoomInfo
- Phone number quality is inconsistent
- Less flexible for custom enrichment workflows
Which Should You Pick?
The Honest Take
These tools serve different users more than they compete directly. Apollo is for sales reps who need contact data and outreach in one click. Clay is for RevOps professionals and growth engineers who want to build custom data pipelines. The teams that get the most from Clay are the ones with someone who enjoys building workflows in spreadsheets. If your team just wants to search a database and start emailing, Apollo is the right tool. Many advanced teams use both: Clay for enrichment, then push enriched contacts to Apollo or Instantly for outreach.
Questions to Ask Before Buying
- Do you have someone on your team who enjoys building data workflows?
- How important is data coverage vs simplicity?
- Do you need built-in email sequences and phone dialing?
- What's your monthly budget for data tools?
- Are you selling into mainstream industries or niche verticals?
- Do you already have a separate outreach tool (Salesloft, Outreach, Instantly)?
Frequently Asked Questions
Can I use Clay and Apollo together?
Yes. A common stack: use Clay for enrichment and data waterfall, then push enriched contacts to Apollo for email sequences and phone outreach. This gives you Clay's superior data coverage with Apollo's outreach execution.
Which has better data quality?
Clay typically produces higher coverage because it queries 75+ sources. Apollo's single database has 80-85% email accuracy. Clay's waterfalling approach can achieve 90%+ by cross-referencing multiple providers. The trade-off: Clay requires more setup time.
Is Clay replacing Apollo?
Not exactly. Clay is an enrichment and research platform without outreach features. Apollo is an all-in-one platform. Clay replaces Apollo's data component but you'd still need Apollo (or another tool) for sequences and dialing. They're complementary more than competitive.
