What Users Say About Clay's Main Features
Clay's main features cover four jobs: building enriched lists, researching accounts with AI, automating GTM plays and keeping the CRM in sync. Here's what reviewers say about each, and how ZoomInfo handles the same work.
Building and enriching lists
This is Clay's core strength. Its waterfall checks providers in sequence until one returns a match, so teams get more coverage than most single data enrichment tools give them.
Ander V., a business development manager, says Clay "pulls information from multiple sources in one place, which saves a huge amount of manual research time."
Anwesh S., a lead development rep, likes that Clay "uses multiple enrichment tools in a single platform, which standardizes the data for us."
The trade-off is that Clay’s enrichment runs on third-party providers rather than one verified database, so quality depends on which providers you connect and how fresh their records are, a common source of B2B data decay.
Chris J. says "the phone number coverage is really weak, with mobile matches only around 30-35%," and Rajat S. says "sometimes the data is not fully correct, so I still need to check it myself."
How ZoomInfo compares: ZoomInfo starts from its own data foundation of 500M contacts, 135M+ verified phone numbers and 120M+ direct dials, verified by 300+ human researchers with up to 95% accuracy on first-party data. GTM Studio then adds built-in waterfall enrichment across 25+ vendors to fill any gaps. Compare more options in our guide to waterfall enrichment tools.
Researching accounts with AI
Claygent, Clay's AI research agent, visits websites to find data points no provider sells, such as open roles or recent news. Reviewers rate it highly.
Chris J. says Claygent "has been particularly useful for handling unstructured tasks, like scanning career pages and pulling recent news."
Manzar I., a sales manager at an enterprise company, says it "can visit company websites to find specific news or signals that I used to search for manually."
The catch is prompt quality. Manzar I. adds that it takes time to "write prompts that work well with the AI."
How ZoomInfo compares: ZoomInfo's AI account research works from the GTM Context Graph, which combines verified company data with your CRM records, conversation history and intent signals, so research starts from what's already known about the account.
Automating GTM plays with agents
Clay has moved from enriching lists to running plays with AI sales agents. Workflows, now in open beta, lets teams build plays visually with agents and code. In October 2026, Clay also introduced a global agent: you describe an outcome, Clay plans and builds the campaign for you to approve, and scheduled tasks keep it running. It's in early access, so most G2 reviews predate it.
ZoomInfo has a multi-agent solution in the form of Agent Teams, available in both GTM Studio and GTM.AI, ZoomInfo's headless layer. The two take different routes to the same goal.
Clay's global agent | ZoomInfo Agent Teams | |
How you start | Describe an outcome, and Clay plans the work for you to approve | Give it an outcome in plain English, or start from 50+ ready-made agents |
Data it works from | Business context in Clay's Knowledge Hub, plus data from Clay's provider marketplace | ZoomInfo's GTM Context Graph and verified data foundation |
What starts it | Scheduled tasks toward a goal | Schedules, CRM events, website visits, completed meetings or webhooks |
Where it acts | Clay's Sequencer, ad audiences and integrations | Build multi-agent orchestration in GTM Studio and via GTM.AI |
Controls | Approval before running a workflow on real records | Monitoring, admin controls and role-based access |
Cost control | Free while in alpha. Enrichments and workflow runs it triggers use Clay credits | A credit estimate before each play runs |
In practice, Clay's agent helps a GTM engineer design campaigns, while Agent Teams runs whole GTM motions end to end for every rep. It works from each account's current state rather than a fixed workflow. In a champion tracking play, for example, an Agent Team spots a past buyer's move to a target account, reconstructs their role in the original deal, drafts outreach and briefs the account owner in Slack.
monday.com used GTM Studio to launch programs four times faster.
"AI is supposed to give you the ability to be creative, to optimize, to see the full picture. It gives you the ability to drop the operations and take your marketing abilities to the next phase."
Keeping your CRM and stack in sync
Integrations are tied for Clay's most cited pro on G2, and reviewers like how far they can stretch them.
Soheil S., a head of service delivery, values that "when a vendor is not available inside it, we can still make HTTP calls to that vendor."
Nick T., a senior business development rep, says it makes his job easier because he's "sourcing companies and contacts directly from one app + doing the enrichments + importing/updating my CRM."
Timing is the limit some teams hit. Soheil S. says "any signal is captured only once a day," which can let leads slip past a CRM block list between syncs.
How ZoomInfo compares: ZoomInfo connects natively to Salesforce, HubSpot and Microsoft Dynamics, keeps records current with CRM data enrichment and starts plays from live events such as website visits and CRM updates. GTM.AI brings the same data to any tool or AI agent through API and MCP.
What It Takes to Run Clay
Clay's biggest strength, flexibility, is also why it's hard to learn. It looks like a spreadsheet, but reviewers say getting real value from it is closer to engineering, which is why Clay has popularized the GTM engineer role.
Chris J. says, "The UI looks like a friendly spreadsheet, but when you need conditional logic and formula chains, it's basically programming."
Ted S., on an IP compliance team, says "there's definitely a learning curve, especially if you're not familiar with enrichment logic or building workflows."
Even happy users agree. Eiad A., a growth marketing specialist, notes a learning curve "particularly when you start building more advanced workflows."
Clay's AI assistant, Sculptor, helps inside a single table and when writing Claygent prompts, and its new global agent can plan and build plays from a goal you describe in plain English. Advanced workflows still take practice.
Support reviews are split. Eiad A. says it's "easy to get practical help from someone who understands the product," while a financial services reviewer says, "Good luck trying to talk to an actual human being."
How ZoomInfo compares: GTM Studio launches with pre-built plays, and RevOps and marketing teams can build an Agent Team in plain language or code and have it live in a day, without engineering support.
Clay Pricing and Credits
Clay charges for two things: Actions, which measure platform usage such as enrichment runs, and data credits, which buy data and AI from vendors in Clay's marketplace. Each Clay plan bundles both, and you can expand either one at any time.
Free: $0, with 6,000 Actions and 1,200 data credits a year, unlimited seats and tables, Claygent and up to 200 rows per table. Phone number enrichment isn't included.
Launch: from $167 a month for 180,000 Actions and 30,000 data credits a year. Adds phone enrichment, Audiences search, signals such as job changes, and sending through Clay's Sequencer or an integration.
Growth: from $446 a month for 480,000 Actions and 72,000 data credits a year. Adds CRM and data warehouse sync, web intent signals, webhooks, any HTTP API, ad audiences and priority support.
Enterprise: custom pricing, with SSO, role-based access with credit budgets by workbook, and a dedicated growth strategist.
Monthly billing costs about 10% more, and every plan lets you bring your own API keys for providers you already pay.
What users say about credits
Credits are the biggest source of negative reviews, mostly because usage is hard to predict.
Chris J. says, "Failed enrichments still burn credits, and we've blown through monthly credits early a couple of times."
A mid-market software user who rated Clay 1/5 says changing a dedupe setting "re-ran the entire workbook and blew through our entire month's credits ($1000 in credits burned) with no clear warning."
krishna S., a founder, says Clay "recently changed the pricing, so they are a bit expensive compared to the previous pricing."
The safest approach is to model a real workflow with Clay's pricing calculator before committing, then set budgets on large tables.
How ZoomInfo compares: Free to start with consumption credits based on usage, ZoomInfo lets teams try the platform before scaling up. Agent Teams runs on one credit meter and shows a credit estimate before each play runs, and GTM Studio's Records Under Management lets you pay for a record once, then re-pull or re-enrich it free for up to a year.

Clay vs. ZoomInfo
Clay and ZoomInfo solve different parts of the same problem. Clay is an orchestration layer that pulls data from many providers and lets you build workflows and agents on top. G2 even lists GTM Workspace, powered by ZoomInfo, among Clay's integrations, so teams can bring ZoomInfo data into Clay.
ZoomInfo is an all-in-one AI GTM Platform that starts with its own data: 500M contacts and 100M companies. The GTM Context Graph fuses that data with your CRM records, conversation intelligence and behavioral signals to explain why deals move or stall. Teams act on it in GTM Workspace for sellers, GTM Studio and Agent Teams for sales, RevOps and marketing, and GTM.AI, ZoomInfo's headless layer for AI agents, for any tool. GTM Workspace is rated 4.5/5 from 9,178 reviews on G2. It's why 37 of the top 40 AI companies run their GTM on ZoomInfo.
The practical difference is who does the building. With Clay, your team assembles the data, workflows and agents. With ZoomInfo, the data and intelligence come built in, so teams hand over the work and keep control.

Who Should Use Clay?
Clay is a strong fit for:
Teams with a dedicated GTM engineering or RevOps builder
Teams that need custom research no data provider sells, using Claygent
Agencies and growth teams running many experimental campaigns
Teams that already pay for several data providers and want one place to combine them
Clay is a weaker fit for:
Teams without someone to build and maintain workflow automation
Budgets that need predictable monthly costs
Phone-led outreach, where reviewers report weaker mobile coverage
Teams that want verified data, intelligence and execution in one platform
Our Verdict on Clay
Clay earns its reviews. For teams with someone who can build and maintain workflows, it's a powerful way to combine data providers, run custom AI research and automate plays that no off-the-shelf tool covers. Its new agents push it further toward running campaigns as well as preparing data.
The trade-offs are just as consistent. Clay takes real technical skill, its data is only as good as the providers you connect, and credits are hard to predict at scale. Teams that want verified data, an intelligence layer and agents that run whole GTM motions end to end without building them from scratch should compare it with ZoomInfo.

Frequently Asked Questions About Clay
What does Clay do?
Clay is a GTM data and workflow platform. Teams use it to build prospect lists, enrich contacts and companies across 150+ data providers, research accounts with its AI agent Claygent and send the results to their CRM, sequencer or ad platforms.
Is Clay worth it?
Clay is worth it for teams with a GTM engineer or RevOps builder who can design and maintain workflows, especially for custom research and multi-provider enrichment. It's a weaker fit for teams that need predictable costs, strong phone coverage or a platform that works without building.
How much does Clay cost?
Clay has a Free plan, then Launch from $167 a month and Growth from $446 a month, with custom Enterprise pricing. Costs can climb because Clay charges for both platform usage (Actions) and the data and AI you pull from providers (data credits), so bigger waterfalls, larger lists and re-runs all add up.
Does Clay have hidden costs?
Clay's pricing is public, but costs can climb because it charges for both Actions and data credits. Reviewers say failed enrichments and re-runs still use credits, so model a real workflow in Clay's pricing calculator and set budgets on large tables before scaling.
Does Clay have AI agents?
Yes. Claygent, Clay's AI research agent, is available on every plan, including Free, and each run uses your plan's credits. In October 2026, Clay also introduced a global agent that plans and builds campaigns from a goal you describe, now in early access. ZoomInfo offers Agent Teams in GTM Studio, which runs whole GTM motions end to end on ZoomInfo's verified data with live triggers, monitoring and a credit estimate before each play runs.
Who owns Clay, and how big is it?
Clay, legally Clay Labs Inc., is a private, venture-backed company based in New York, led by co-founder and CEO Kareem Amin. It raised a $115M Series D in 2026 at a reported $7.1B valuation and has passed $100M in annual recurring revenue. Clay says more than 500,000 GTM teams use it.
Is Clay better than Apollo?
It depends on your team. Apollo suits small sales teams that want a contact database, sequencing and a dialer in one low-cost tool. Clay suits teams with a GTM engineer who need custom enrichment and research across many providers. Teams that want verified data, an intelligence layer and AI agents in one platform often compare both with ZoomInfo.
What are the best Clay alternatives?
ZoomInfo is a strong alternative for teams that want verified data, an intelligence layer and AI agents in one platform. Apollo suits small teams that want data and sequencing in one low-cost tool, as our Apollo reviews show. Our Clay alternatives guide compares more options.
