Clay vs Apollo: Which One Fits Your Prospecting Workflow?

Clay vs Apollo comes down to this: pick Apollo if you want one tool that finds contacts, reveals emails and sends sequences for a fixed per-seat price. Pick Clay if you have someone who will build workflows, and you need data from many providers plus AI research in the same table. Apollo is a database with outreach attached. Clay is a workflow builder with a data marketplace attached.

Many teams end up running both: Clay's Apollo integration lets you call Apollo from inside a Clay table with your own Apollo account [1][5]. The question is which one sits at the center of your process.

What is the core difference between Clay and Apollo?

Apollo sells access to its own database, and Clay sells access to everyone else's. Apollo says its data covers 240M+ contacts and 30M+ companies, and it runs search, sequencing, a dialer and CRM sync on top of that [2][3]. Clay lists 150+ data partners on its pricing page and charges you per enrichment and per action as you build tables that combine them [1].

That difference drives everything else. In Apollo, the default unit of work is a saved search and a sequence. In Clay, the default unit of work is a table where each column is a step you configure.

How do Clay and Apollo compare side by side?

The short version is in the table. Prices are as of October 2026; check the Clay pricing page and Apollo pricing page before you buy.

	Apollo	Clay
Data source	Own database: 240M+ contacts, 30M+ companies [3]	Marketplace of 150+ providers, plus your own API keys [1]
Waterfall enrichment	Apollo data first, then 20+ partners; emails and phone numbers only [3]	Any data point, any provider order you choose [7]
AI research	AI Research at 1 credit per run; AI filters and scores [2]	Claygent agents with web access; "Use AI" for writing and classification [6]
Outreach	Sequences, dialer, mailboxes built in [2]	Clay Sequencer, or push to your existing tool [1]
Pricing model	Per seat, credits pooled across the team [2]	Platform fee in Actions plus Data Credits; unlimited seats [1]
Entry paid price	Basic $49/seat/mo annual, $65 monthly [2]	Launch from $185/mo monthly (Actions plus Data Credits) [1]
Free plan	75 credits/mo [2]	100 Data Credits, 500 Actions/mo, 200 rows per table [1]
Learning curve	Low: filters, lists, sequences	High: you design the workflow
Best for	Reps and small teams running volume outbound	GTM engineers building custom enrichment and scoring

Where does each tool get its data?

Apollo answers most lookups from its own records, and reaches outside only when a field is empty. Its Waterfall Enrichment "fills each record with Apollo data first, then lets 20+ partners fill in the rest," and you choose the partner order [3]. Apollo's FAQ says the waterfall currently covers emails and phone numbers [3].

Clay has no primary database you are locked into. Its waterfall page lists providers such as Prospeo, DropContact, Datagma, Hunter, People Data Labs, Apollo, Lusha and Snov for work emails, and says you can waterfall "any data point," including tech stacks and job openings [7]. If a lookup returns nothing, Clay charges neither Data Credits nor Actions [1].

The trade-off is accuracy versus simplicity. In our test on 100 accounts, Apollo found contacts at 98 of 100 companies, but 26 held outdated titles. Clay's multi-provider lookups resolved valid emails at 91 of 100 accounts, at an average of 4.2 credits per row for a three-provider waterfall plus a Claygent lookup [9].

How does the day-to-day workflow differ?

Apollo is filter, select, act. You open People or Companies, apply filters, then save, list, sequence, export or push to CRM from an action bar [4][5]. Apollo uses AND logic across filters and OR logic inside a filter, and shows up to 100 pages of results [5].

Clay is build, run, check. You start a table from a source, then add columns one at a time: find people, find email, validate, research with AI, score, export. Each column can call a different provider, and Claygent can read websites to fill fields no database stores [6]. For a step-by-step version, see our Clay tutorial, and for ready-made starting points, our list of Clay templates.

Expect the setup gap to be real. A rep can run a useful Apollo search on day one. A useful Clay table takes an hour or more the first time, and complex ones are a GTM engineer's job.

What does one prospecting job look like in each tool?

Take one job: find heads of RevOps at US B2B software companies with 50 to 500 employees that are hiring SDRs, get verified emails, and start a sequence. Both paths below are described from each vendor's documentation, not from a new test.

In Apollo

1. Click Companies, then Show Filters > More Filters. Set Location to United States, # of employees to 51–500, Industry & keywords to software, and Job postings to "Sales Development Representative" [4][5].
2. Bulk-select the results and choose Find people. Apollo opens a people search scoped to those companies [4].
3. Add Job titles (Head of RevOps, Director of Revenue Operations) and seniority filters, then save the contacts to a list [5].
4. Reveal emails at 1 credit each. Fifty contacts cost 50 credits, inside the Basic plan's 2,500 monthly credits [2].
5. Select the list and enroll it in a sequence [5].

Record selection limits apply per action: 1,000 records on Basic, 2,500 on Professional, 10,000 on Organization [2]. Apollo's job-postings data is its own, so you are trusting its refresh cycle for the "hiring SDRs" signal.

In Clay

1. Create a table with the Find Companies source: United States, software, 50 to 500 employees, plus a semantic description of your ICP. Or import the account list you already have as a CSV [10].
2. Add Find People scoped to those companies, with RevOps titles and a limit of one or two people per company. Sourcing people uses no Actions [11][12]. You can also use the "Find People at Company By Job Title" action with your own Apollo account [8].
3. Add the Work Email waterfall with a Conservative validation strategy. It stops at the first valid result and charges only the provider that found it [13].
4. Add a Claygent column that opens each company's careers page and returns "yes" plus the job URL if an SDR role is open [6].
5. Filter to rows where the Claygent column says yes, then send them to Clay Sequencer, your sequencing tool or your CRM [1].

Clay's own example puts 100 contacts with profiles and emails at about 95 Data Credits, or 50 with your own email provider key, plus 1 Action per enrichment and per export [12]. Clay costs more steps and more decisions. In exchange, the hiring signal is checked live on the company's own site, with a URL you can audit, and each step can use a different provider.

How do Clay and Apollo charge you?

Apollo charges per seat, and Clay charges for usage with unlimited seats. As of October 2026, Apollo's Basic plan is $49 per seat per month billed annually ($65 monthly) with 2,500 credits a month, Professional is $79 annually ($99 monthly) with 4,000, and Organization is $119 per seat annually with a 3-seat minimum and 6,000 credits [2]. An email costs 1 credit and a phone number costs 8 [2]. Credits pool across the team and do not roll over [2].

Clay's Launch plan starts at $185 a month billed monthly, with 2,500 Data Credits and 15,000 Actions; Growth starts at $495 with 6,000 Data Credits and 40,000 Actions [1]. Data Credits start at $0.05 each, roll over up to 2x your monthly amount, and are skipped entirely if you bring your own API keys [1]. Actions reset monthly.

For a five-rep team, Apollo Professional costs $395 a month on annual billing before add-ons. Clay Growth costs $495 a month on monthly billing regardless of seat count. The detailed breakdowns live in our Clay pricing and Apollo pricing guides.

Which one should you choose?

Choose Apollo when your bottleneck is volume and your team is mostly reps. It is cheaper per person, needs no builder, and keeps search and sequencing in one screen. Accept that its database will carry stale titles, and that the waterfall only fills emails and phones [3].

Choose Clay when your bottleneck is data quality or custom signals, and you have a GTM engineer. It is the better tool for scoring accounts, combining providers and running AI research on every row. If you are also weighing an enterprise database, read Clay vs ZoomInfo.

Use both when you want Apollo's sequencing and Clay's enrichment. Clay's Apollo actions can add contacts to Apollo sequences and update Apollo contacts directly [8].

Neither tool is built to read logged-in sources such as a buyer's Reddit thread or a new VP's LinkedIn posts. In our 100-account test, Clay's cloud requests to strict platforms often hit anti-bot barriers or returned truncated HTML [9]. That is where browser-based research fills the gap. Drevon reads those sources in your own browser session and returns a brief where every claim links to its source, then exports to Clay or HubSpot. Our earlier Clay, Apollo and Bardeen comparison covers how browser-based tools fit next to Apollo.

Frequently asked questions

Is Clay better than Apollo?

Clay is better for custom enrichment and AI research; Apollo is better for fast, cheap volume outbound. If nobody on your team will build workflows, Apollo is the better buy.

Can you use Apollo inside Clay?

Yes. Clay's Apollo integration includes Enrich Person, Enrich Company, Find People at Company By Job Title and Add contact to sequence, and each requires your own Apollo account [8].

Is Apollo cheaper than Clay?

Per seat, usually yes. Apollo Basic is $49 per seat per month on annual billing [2]. Clay's paid plans start at $185 a month but include unlimited seats [1], so Clay can be cheaper for large teams with light usage.

Does Clay have its own contact database?

Clay mainly resells data from its partners through Data Credits, and supports unlimited search with Audiences on paid plans [1]. Apollo is the one with its own primary database [3].

Do Clay and Apollo credits roll over?

Apollo credits expire at the end of each billing cycle, including add-on credits [2]. Clay Data Credits roll over up to 2x your monthly amount on Launch and Growth; Actions do not roll over [1].
