Apollo vs ZoomInfo vs Clay (2026): Which B2B Prospecting Tool to Buy at Your Team Size

Last updated November 7, 2026 · 8 min read
Choose Apollo if you have fewer than about 15 reps and need a contact database and email sequences in one login for roughly $49 to $79 per user per month. Choose ZoomInfo if you sell into large North American companies, have 25 or more sellers, and can sign an annual contract that buyers report in the tens of thousands of dollars. Choose Clay only when someone on the team (usually a RevOps or growth hire) will build enrichment workflows, and budget for the $495-a-month Growth plan if you need it to sync with your CRM.
Monday, 9:15 a.m. Your new SDR loaded 400 VP of Finance contacts into a sequence on Friday. Sixty-one bounced over the weekend, the domain warmup score dropped, and the two replies that came in were both from people who left their company in the spring.
That is the week someone opens three pricing pages.
Apollo, ZoomInfo and Clay show up on every shortlist for B2B prospecting data, and they are sold as if they compete head to head. They mostly do not. Apollo is a database with a sales engagement tool bolted on. ZoomInfo is a database sold to enterprises on annual contracts. Clay began as a layer over other companies’ data. It rents dozens of providers and lets you script what happens to each row.
Plans and limits come from the Apollo, ZoomInfo and Clay pricing pages, checked November 7, 2026. Clay publishes exact prices. Apollo’s page loaded plan names and credit rules but no dollar amounts when we checked, so the Apollo prices below are the figures widely reported this year and marked that way. ZoomInfo publishes nothing. SaaS Versus does not sell prospecting data, and the site footer notes that some links may be affiliate links.
Apollo vs ZoomInfo vs Clay at a glance
| Feature | Apollo | ZoomInfo | Clay |
|---|---|---|---|
| Starting paid price | About $49/user/month on annual billing (Basic, widely reported) | Not published; quote only | $185/month, or $167/month annual (Launch) |
| Free plan | Yes, for light use; Gmail only for email | Free trial on some use cases, terms not stated | Yes: 100 data credits, 500 actions a month, 200 rows per table |
| Plans | Free, Basic, Professional, Custom | Custom packages by use case | Free, Launch, Growth, Enterprise |
| Pricing model | Per seat, plus team-pooled credits that reset each cycle | Annual contract; API and MCP priced on usage | Flat plan with unlimited seats; you buy actions and data credits in tiers |
| CRM sync | Core integrations on Basic; advanced on Professional | Yes, scoped in the contract | Growth plan and up only |
| Built-in email sequencing | Yes, from Basic | Available in its wider platform; ask what your package includes | Email campaigns from Launch |
| API access | Custom plan | Usage-priced | HTTP API from Growth |
| Best for | Founders and sales teams under about 15 reps | Enterprise sales orgs selling into large North American accounts | RevOps-led teams that want to combine several data sources |
| Biggest drawback | Credits expire every cycle, and phone numbers burn them fast | No price until you talk to sales, and annual lock-in | Somebody has to build and maintain the workflows |
What a five-rep team pays in year one
Same team in every row: five sellers, one sales manager who also does ops, HubSpot as the CRM. The numbers are list prices or labeled estimates, before any negotiation.
| Setup | Year-one cost | Source of the number | What it leaves out |
|---|---|---|---|
| Apollo Basic, 5 seats, annual | About $2,940 | $49/user/month, widely reported | Extra credits if reps pull a lot of mobile numbers; advanced CRM features sit on Professional |
| Apollo Professional, 5 seats, annual | About $4,740 | $79/user/month, widely reported | Add-on credits, which Apollo charges immediately when bought |
| Clay Growth, annual, entry credit tiers | $5,352 | $446/month on clay.com | Your own data provider keys if you bring them, plus a separate sequencing tool unless you use Clay’s |
| ZoomInfo | Quote only | Buyer-reported contracts mostly land in the tens of thousands per year | Everything you will learn on the sales call, including the renewal increase |
Clay Launch would be cheaper than Growth at $2,004 a year on annual billing. It does not sync to HubSpot. For most teams that ends the conversation about Launch.
Apollo: the default for teams that cannot wait for procurement
Apollo’s whole appeal is that a founder can sign up with a credit card on a Tuesday, find 300 heads of engineering at Series B fintechs by lunch, and have a five-step sequence running before the end of the day, without a contract or anyone from finance getting involved.
The credit rules are where it gets you. Credits are pooled across the team and granted at the start of each billing cycle, and anything unused expires at the end of it (purchased add-on credits included). Third-party breakdowns of Apollo’s credit costs put a mobile number at several times the cost of a verified email, so one SDR who reveals every phone number in a 500-contact list can drain a month of team credits by Wednesday. Admins can cap credits per user. Turn that on during week one.
One more rule that trips people up: every seat on an Apollo account has to be on the same plan. You cannot put two power users on Professional and leave the rest on Basic.
Data quality is the long-running complaint, and it is fair. Apollo’s database is large and cheap, and some share of it is stale at any moment. Verify emails before a big send and you will mostly be fine.
ZoomInfo: the enterprise answer, priced like one
ZoomInfo’s argument is depth on large North American companies: direct dials, reporting lines, technographics and intent signals for accounts where you need the name of the third person in the procurement chain. Teams selling six-figure contracts into the Fortune 1000 tend to stick with it for exactly that reason, and if your reps spend their day on the phone, test its direct-dial coverage against Apollo’s on 50 of your real target accounts before deciding.
Everything else about ZoomInfo is opacity. Its pricing page sells packages by use case behind a form. The FAQ on that page asks whether you can pay monthly and what credits are, then gives no answers. Procurement-data sites publish buyer-reported contracts, and most of what they report sits in the tens of thousands of dollars a year for a mid-size team. We could not check those numbers against any list price, so use them as leverage in the negotiation and leave them out of the budget.
Read the auto-renewal clause twice.
Clay: a data workbench for someone who likes spreadsheets
Clay works like a spreadsheet where every column can call an API. You load a list of target companies, find people at each one, then run a waterfall: try provider one for a work email, fall through to provider two if it comes back empty, then three. Claygent, its AI research agent, can read a prospect’s website and fill in a column like “do they mention SOC 2 on their security page.” Done well, it gives you match rates and personalization nobody on a single database can touch.
Done badly, it is a $5,000 spreadsheet nobody opens after March.
Pricing is the most transparent of the three by a wide margin. Clay splits usage into actions and data credits, sells each in tiers, and lists every tier with its price on the page. The catch is in the plan gates. CRM integrations, the HTTP API, webhooks and web intent signals all start at Growth, and data warehouse connections plus SSO are Enterprise only. Clay’s own page also contradicts itself in places (its FAQ and plan table disagree on Launch’s starting data credits and on how much rolls over), so get the allowance written into the order form.
Where each option fits (and where it does not)
| Option | Fits | Does not fit |
|---|---|---|
| Apollo | Founder-led sales and teams up to roughly 15 reps who want data and sequencing in one tool, paid on a card this week | Teams whose reps live on the phone and burn mobile-number credits, and regulated buyers who need SSO without moving to a custom contract |
| ZoomInfo | Sales orgs of 25 or more selling into large North American enterprises, where org-chart depth and direct dials justify an annual contract | Startups that need a price before a demo, and anyone who cannot commit to a full year |
| Clay | Teams with a RevOps or growth person who will own enrichment, and companies already paying for one data source that want to fill its gaps | Teams without a builder, and anyone who needs CRM sync but only has budget for Launch |

Clay: Strengths and Weaknesses
✓Pros
- ✓Every plan and credit tier priced publicly, with unlimited seats
- ✓Waterfall enrichment across many providers, plus Claygent for AI research columns
✗Cons

The Verdict
Under 15 reps, buy Apollo Professional, cap credits per user in the first week and verify emails before every large send. It is the cheapest way to get a working outbound motion, and you can leave without a contract fight. Add Clay Growth once you hire a RevOps person who asks for it by name; that is the signal someone will actually maintain the tables. We would only sign a ZoomInfo contract with 25-plus sellers working enterprise accounts, after a 50-account coverage test against Apollo, and with the renewal cap in writing. For that buyer it can be the right call. For most startups reading this page, it is a year-one budget line that Apollo covers for a fraction of the price.
Frequently Asked Questions
How much does Apollo.io cost in 2026?
Apollo sells four plans: Free, Basic, Professional and Custom. Its pricing page loads prices in an interactive calculator, and the figures widely reported in 2026 are $49 per user per month for Basic and $79 per user per month for Professional on annual billing, with monthly billing costing more. Credits are pooled across the team, granted at the start of each billing cycle and do not roll over. Every seat on an account has to be on the same plan.
How much does ZoomInfo cost?
ZoomInfo does not publish prices. Its pricing page sells custom packages by use case (prospecting, account-based marketing, enrichment and others) behind a Get pricing form, and prices API and MCP access on usage. Buyer-reported contract data from procurement sites puts a typical annual contract in the tens of thousands of dollars, but those figures are secondhand and you will only get a real number from a quote.
How much does Clay cost?
Clay publishes everything. Free is $0 with 100 data credits and 500 actions a month and a 200-row limit per table. Launch starts at $185 a month, or $167 a month on annual billing. Growth starts at $495 a month, or $446 a month annually, and is the first plan with CRM integrations, the HTTP API and webhooks. Enterprise is quoted. Every plan includes unlimited seats.
Is Clay a replacement for Apollo or ZoomInfo?
Partly. Clay is a workflow and enrichment tool that queries many data providers in sequence (a waterfall) and pays for them with Clay credits. You can prospect inside Clay without a separate database, but many teams use it on top of Apollo or ZoomInfo exports to fill in missing emails and phone numbers and to write personalized first lines. If nobody on your team will build and maintain Clay tables, it is the wrong first purchase.
Which is cheapest for a small sales team?
Apollo. A three-rep team on Basic pays roughly $1,764 a year at the widely reported $49 per user per month annual price, and that includes the contact database, email sequencing and core CRM integrations. Clay Launch is $2,004 a year on annual billing with unlimited seats but no CRM sync, and ZoomInfo contracts are quoted far above either.
Does Clay connect to Salesforce or HubSpot on the Launch plan?
No. Clay's pricing table lists CRM integrations, auto-sync and enrichment as starting on Growth ($495 a month, or $446 a month annually). On Launch you can export CSVs or push through email campaign integrations, but not sync records to a CRM.
