Clay vs Apollo vs ZoomInfo: which fits your team

Clay, Apollo and ZoomInfo do different jobs. Apollo is a self-serve contact database with email sequences and a dialer built in. ZoomInfo is an enterprise data and intelligence platform sold on quote-based contracts. Clay is a data and workflow platform that enriches records from 150+ data providers, and it can pull from your own Apollo or ZoomInfo account too.

So in Clay vs Apollo vs ZoomInfo, the right choice depends less on the data and more on who will use the tool, and how often. There’s no single winner. Each one is the right pick for a certain kind of team, and you can run two of them together. All prices are as of October 2026.

Clay vs Apollo

Apollo is where a rep works. Clay is where a builder builds.

Apollo puts a contact database, email sequences, a dialer and basic deal management in one self-serve tool. Its plans are per seat: Basic is $49 per seat per month billed annually with 30,000 credits per seat per year, Professional is $79 with 48,000, and Organization is $119 with 72,000 and a three-seat minimum. An email costs 1 credit and a phone number 8. Credits are pooled across the team, and they don’t roll over. Every seat on an account has to be on the same plan.

Clay doesn’t charge per seat. You pay for usage: Actions for the work Clay does, and Data Credits for the data it buys from providers. You can search for companies and people in Clay’s database without using credits, then enrich them through waterfalls. A waterfall tries one provider, then the next if the first finds nothing, which is how you raise coverage. Clay also handles CRM sync, signals and AI research, so it can run the same workflow every day instead of once. The Clay pricing guide walks through the plans and a worked example.

The difference shows up in who runs it. Apollo is built for reps to use directly. Clay rewards someone who likes building, usually a GTM engineer or a RevOps lead.

Clay vs Apollo is also not either/or. Clay’s Apollo integration lets you enrich people and companies from Apollo inside Clay, using your own Apollo account. So you can prospect and send from Apollo, and run Clay behind it for enrichment and routing.

Apollo vs ZoomInfo

Both are contact databases with tools on top. They’re sold very differently.

Apollo publishes its prices, sells by the seat and lets you pay monthly or annually. Apollo’s own FAQ describes Basic as the plan for individual sellers doing regular outbound, and Professional for full-time reps who need more credits and AI features. It suits small and mid-sized teams that want to start this week without a sales process.

ZoomInfo sells through its sales team. Its pricing page lists packages but no prices, and Vendr’s data from 1,578 purchases puts the median contract at $33,500 a year. For that you get a platform designed for daily use by larger teams. The Professional package includes mobile numbers and business emails. The Copilot packages add account scoring, buyer intent, website visitors and buying group data, and the marketing packages add audience targeting and ABM advertising.

If you have 30 reps who live in the tool, ZoomInfo’s volume pricing and depth can make sense. If you have three, Apollo’s published per-seat price is easier to start with. The ZoomInfo pricing guide covers what to negotiate if you go that way.

Clay vs ZoomInfo

These two sit at different layers, so they’re often complements. ZoomInfo is a data source. Clay is where you combine data sources into workflows.

Clay’s ZoomInfo integration enriches companies and contacts from a connected ZoomInfo account. If you already pay for ZoomInfo, you can put it first in a Clay waterfall and let other providers fill the gaps. If you don’t, Clay’s marketplace gives you access to many providers without a separate contract with each.

Which one fits your team

Four questions settle most decisions:

1. How many people will use it every week? One builder points to Clay. Several reps prospecting daily point to Apollo or ZoomInfo.
2. Do you have someone who builds workflows? If yes, Clay will repay their time. If not, Apollo works out of the box.
3. Do you want outreach in the same tool? Apollo includes sequences and a dialer. Clay sends email through its sequencer or integrations. ZoomInfo connects to the outreach tools you already use.
4. Monthly budget or annual contract? Apollo and Clay both offer monthly billing. ZoomInfo deals are negotiated, usually as annual contracts.

What a 50,000-contact list costs in each

If your goal is one list of your market, here’s roughly what each tool costs for 50,000 contacts with work emails, from the published prices:

• Apollo: two Basic seats give 60,000 credits a year for $1,176. Phones push it higher, at 8 credits each.
• Clay: a lean LinkedIn-and-email build fits one month of Launch at about $2,665, using Clay’s own credit rates. Richer workflows run higher.
• ZoomInfo: the median contract is $33,500 a year. That buys a year of a platform for your team, not just one list.

Those are tool costs only. The person running the build is usually the bigger line, and intent data can be bigger still. The cost of building a TAM in-house adds those up.

When a managed TAM build is the sensible first step

Sometimes the question isn’t which tool to buy, but whether you need one yet. A managed build from a GTM agency makes sense as a first step when:

• Nobody on your team has the hours to run the tools right now.
• You want to see your whole market, counted and scored, before you choose a tool or hire.
• You need to know which accounts to work first this quarter, not after a six-week build.

That’s the job AdsGTM does. We’re a GTM agency that maps every ICP-fit company and buyer in your market as a managed service. You get LinkedIn URLs, verified work emails and optional phone numbers, and every company is scored. The list is split into Sales-ready (contacts at companies showing buying intent now, usually around 5%) and Marketing-ready (the rest of your market). It’s delivered to HubSpot, Salesforce, Attio or a CSV within 72 hours of a 30-minute kickoff call, for a one-time price from $2,900 (see pricing and how it works).

It doesn’t replace a tool your team uses every day. Reps still need somewhere to prospect and send, and ongoing workflows still need a platform like Clay and someone to run it. A mapped market just means that whichever tool you pick starts from the full list of buyers, not a few hundred names.
