This article is for founders, CMOs and revenue leaders who are about to renew a big B2B data contract and wonder whether there is a better way to buy contact and company data. We write it as long-time ZoomInfo customers, and happy ones.
Should you buy a full ZoomInfo subscription or use Clay?
Buy a full ZoomInfo subscription when a large sales team prospects in the database every day and needs direct dials, org charts, intent data and one vendor. Use Clay when a lean team needs specific lists, enrichment of inbound leads and custom signals: it pulls from more than 150 data providers in a waterfall, adds an AI research agent, and charges for the credits you use instead of a full annual platform contract. You can also connect your ZoomInfo account inside Clay and use both.
AI Summary
For years the standard way to get B2B data was to buy a full subscription to one large database, and ZoomInfo was the best of them. We were very satisfied ZoomInfo users and had their API for years. Clay changes the model: instead of buying one whole database up front, you build a table, pull from more than 150 data providers in order until one has the answer, add an AI agent that researches each company on the web, and pay for the credits you use. A full ZoomInfo subscription still makes sense for large sales teams that prospect in the database all day. For lean teams that need specific lists, enrichment and custom signals, Clay is usually the better buy, and you can even plug your ZoomInfo account into it.
The Old Way: Buy the Whole Database
The old way was simple. You signed an annual contract with ZoomInfo, gave your reps seats, got a pool of export credits, and bought API access so the data could flow into your other systems. In return you got one of the largest and best-maintained B2B databases in the world: contacts, direct dials, company firmographics, org charts, technographics and intent signals, all in one place and from one vendor.
We want to be clear about our own experience. We were very satisfied ZoomInfo users, and we had their API for years. The data was good, and the API is what made it useful: records went into the CRM and marketing automation automatically instead of being exported to spreadsheets by hand. Nothing in this article is a complaint about ZoomInfo's data.
What defined the old way was not quality. It was the shape of the purchase:
- You bought everything to use a slice. Most teams only need a fraction of the database, but the subscription is priced for the whole platform.
- You committed for a year. Pricing is negotiated, contracts are annual, and the cost grows with seats, credits and add-ons such as intent data and API access.
- You had one source. When ZoomInfo did not have an email, a phone number or a niche company, there was no second place to look inside the same workflow.
The New Way: Clay
Clay is not a database. It is a workbench for data. You start with a table of companies or people, then add columns that fill themselves in. Each column can call a data provider, an AI model or any API, and the result feeds the next column.
Waterfall enrichment
The idea that changes the economics is the waterfall. To find a work email, Clay can ask one provider, and if that provider comes back empty, ask the next one, and the next, until one returns an answer. You pay only for the lookups that run. Because no single provider covers every company and every person, a waterfall across many sources usually finds more than any one database does on its own.
Claygent: research that is not in any database
Clay also includes Claygent, an AI agent that reads websites and searches the web to answer questions you write in plain language. Does this company sell to hospitals? Do they have a partner program? Did they just open an office in Europe? Those answers are not fields in a traditional database. With Claygent they become a column you can filter and score on.
Pricing you can start small with
As of October 2026, Clay has a free plan, a Launch plan starting at $167 a month and a Growth plan starting at $446 a month that adds CRM sync, webhooks and calls to any HTTP API. Enterprise is custom. Plans are priced in credits for data and actions, so cost follows how much you actually enrich.
Clay vs ZoomInfo at a Glance
| The old way: a full ZoomInfo subscription | The new way: Clay | |
|---|---|---|
| How you buy | An annual contract for a full platform, priced by seats, credits and modules | A monthly or annual plan priced by credits, with a free tier to start |
| Where the data comes from | ZoomInfo's own database, researched and maintained by ZoomInfo | 150+ providers in one table, tried in order until one returns an answer (a waterfall) |
| API and CRM sync | Available, usually as part of a larger package | CRM sync and calls to any HTTP API on the Growth plan and up |
| Research beyond the database | Intent signals, org charts, technographics and news from ZoomInfo | Claygent, an AI agent that reads websites and the web to answer custom questions about each company |
| Who does the work | Reps search and export inside ZoomInfo | One builder sets up tables and workflows that run on their own |
| Best for | Sales teams that live in the database every day | Lean teams that need specific lists, enrichment and custom signals |
You Do Not Have to Choose
Clay and ZoomInfo are not strictly rivals. ZoomInfo is one of the providers you can use inside Clay: you connect your own ZoomInfo account and run its company and contact enrichment as a column in a Clay table, alongside other providers and Claygent. Teams that already trust ZoomInfo's data can keep it as their first source and let Clay fill the gaps.
When a Full ZoomInfo Subscription Still Makes Sense
- Many reps prospect all day. If a large sales team searches, builds lists and calls from the database every day, a platform built for reps is worth paying for.
- You need direct dials and org charts at scale. ZoomInfo's phone coverage and its view of who reports to whom are hard to match by stitching sources together.
- You want one vendor. One contract, one support team, one compliance review and one place to point when data is wrong.
- You run on intent data. If your plays start from ZoomInfo's buying signals, the full platform keeps them in the same system as the contacts.
When Clay Is the Better Buy
- A small team needs specific lists. You know your ideal customer and need the right few thousand records, not access to the whole database.
- You enrich inbound leads. Form fills, event lists and website visitors get completed and scored automatically before they reach sales.
- Your best signals are custom. The questions that predict a good customer for you are things Claygent can find on a website, not standard fields.
- You want to start without a big contract. You can prove the workflow on the free or Launch plan before committing real budget.
- You already think in workflows. If you used an API to wire data into your systems, Clay will feel natural. It is the same idea with the plumbing already built.
What Changed
The old way assumed that data was scarce and that the hard part was owning the biggest database. Today data is spread across many good providers, and AI agents can read the web for anything that is missing. The hard part now is knowing which questions to ask and wiring the answers into your CRM, your marketing automation and your sales process. That is a build problem, not a buying problem, which is why we think about it the same way we think about running AI agents for your business and choosing a marketing platform such as HubSpot or NetSuite.
The Other Side of the Table: AI Is Researching You Too
When a buyer's team uses Clay, Claygent and similar agents read your website to decide whether you belong on their list. If your site hides what you do, who you serve and where you operate in images, scripts or vague copy, the agent gets it wrong or skips you. The same tools that make prospecting smarter make a machine-readable website more important.
