FullEnrich vs. Clay Comparison

Choosing between FullEnrich and Clay for your B2B data enrichment often comes down to five questions:

• Do you need contact data only, or do you also need workflow automation, intent signals, and outreach execution?

• Is your team technical enough to build custom enrichment workflows, or do you want something that works out of the box?

• Are you enriching leads you already have, or do you need to find and qualify new prospects from scratch?

• How important is it that your data provider understands why accounts are in-market, not just who works there?

• Do you want to assemble your own stack from multiple vendors, or would you rather have one platform that handles data, intelligence, and execution together?

In short, here is what we recommend:

FullEnrich is the specialist pick for teams whose main problem is missing contact data. It queries 20+ data vendors in sequence until it finds a verified email or phone number, producing an 80%+ find rate that no single vendor matches. FullEnrich earns 4.8/5 from 79 G2 reviews with a 9.7/10 ease-of-use score -- the highest in the enrichment category.

Pricing starts at $29/month with unlimited seats and a credit model that charges only when data is found. The tradeoff: it does one thing. No intent data, no workflow automation, no outreach tools, and CRM integrations beyond HubSpot are still "Coming Soon".

Clay is the builder's platform for GTM teams that want to design their own enrichment and automation workflows from scratch. Its spreadsheet interface connects to 150+ data providers, lets you layer AI research agents, intent signals, and conditional logic across every row, then push results to your CRM or sequencer. Clay rates 4.7/5 from 185 G2 reviews with an 8.0/10 ease-of-use score -- lower than FullEnrich's, reflecting the platform's steeper learning curve.

Companies like Anthropic, OpenAI, and Rippling run their GTM operations on it. But that power comes with a steep learning curve, a dual-currency pricing model (Actions plus Data Credits) that is hard to predict at scale, and the reality that Clay orchestrates other people's databases rather than owning data itself.

Both platforms solve the enrichment problem from different angles: FullEnrich by simplifying multi-vendor contact discovery into a single click, Clay by giving technical teams a workspace to build any GTM workflow they can imagine. But neither provides proprietary data, neither captures buying intent from your deal history, and neither offers AI that understands the context behind your accounts. That gap matters when you move beyond enrichment into execution.

ZoomInfo is an all-in-one AI GTM Platform built on the largest B2B dataset available: 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business email addresses. That data fuels ZoomInfo's GTM Context Graph, an intelligence layer that connects your CRM records, conversation transcripts, and behavioral signals with the 1.5B+ data points ZoomInfo processes daily.

It captures why deals move or stall, so the AI drafting your next follow-up understands the concern behind the conversation, your next GTM play targets accounts matching your actual win patterns, and your next forecast reflects buying evidence rather than rep optimism. Your team can use this intelligence through the GTM Workspace for sellers, GTM Studio for marketers and RevOps, or APIs and MCP in any front-end.

FullEnrich vs. Clay vs. ZoomInfo at a glance

The enrichment-only problem

FullEnrich and Clay both address a real pain point: single data providers miss too many contacts. When one vendor covers 40-60% of your target list, you are leaving half your addressable market untouched.

FullEnrich solves this the simplest way possible. Upload a CSV with names and companies, click enrich, and the platform queries 20+ vendors one by one until it finds a verified email or phone number. The triple verification layer removes up to 32% of bad emails before they reach you, producing a sub-1% bounce rate on valid addresses. For US and Canada phone numbers, a telecom partnership verifies that the number belongs to the named person.

Clay solves it with more flexibility. You configure the waterfall yourself: which providers to query, in what order, with conditional logic (look for mobile numbers only if work email was not found), and AI research layered on top. Clay's approach gives you more control (you can build waterfalls for any data point, not just contact info) but it requires understanding which providers to use, how to structure the sequence, and how credits flow across each step.

Both approaches improve coverage. But coverage is table stakes. Knowing a prospect's email address does not tell you whether they are evaluating solutions, what their buying committee looks like, or which signals predict a closed deal. That requires intelligence, not just data.

FullEnrich wins on simplicity and cost

If your problem is "I have a list of names and I need their contact info," FullEnrich is a solid choice.

The pricing makes the case. At $29/month for 500 credits, a work email costs 1 credit ($0.058 per email found) and a mobile phone costs 10 credits ($0.58 per mobile). Invalid results cost nothing. For a team enriching a few hundred leads per month, total cost stays well under $100/month. FullEnrich earns 4.8/5 from 79 G2 reviews with a 9.7/10 ease-of-use score -- reflecting how quickly new accounts get productive on it.

The regional coverage also stands out. US-centric providers often lose accuracy outside North America. FullEnrich publishes find rates by region: 89% email coverage in US/Canada, 84% in EMEA, 78% in LATAM and APAC. For teams selling internationally, this geographic range is a real differentiator over a single-source US provider.

With the February 2026 launch of FullEnrich Search, the platform added prospecting with 15+ filters, removing the need for external list-building tools. It is no longer just an enrichment layer; it is becoming a simple end-to-end outbound data tool.

But the scope stops there. FullEnrich does not return LinkedIn URLs, does not provide intent data or technographics, and cannot enrich from company name and job title alone without an identifying input like a LinkedIn URL or full name. Native CRM integrations are thin: HubSpot is live, but Salesforce, Pipedrive, and outreach tools are all "Coming Soon". Non-HubSpot teams must bridge via Zapier, Make, or n8n, adding a third-party dependency and latency to every enrichment workflow.

For teams whose bottleneck is contact data and nothing else, these limitations do not matter. For teams that need to know which contacts to prioritize, what to say, and when to reach out, FullEnrich solves the first step but leaves the rest untouched.

Clay wins on flexibility and creative control

Clay takes the opposite approach: instead of a pre-built waterfall, you get a blank workspace.

The spreadsheet interface lets you connect any combination of 150+ data providers, layer in AI research via Claygent (which has completed 1 billion+ lifetime runs), and build conditional workflows that route leads through different enrichment paths based on company size, geography, or any other attribute.

Need to check if a prospect's company appeared in a competitor's case study? Claygent can browse the web and return structured answers at scale.

This flexibility has made Clay the go-to for technical GTM teams. Anthropic tripled their enrichment rate using Clay's multi-provider waterfalls. Intercom's GTM Ops director said Clay enabled more "what if we could..." questions than any prior tool. The platform spawned an entire job category (the GTM Engineer) with 400+ jobs posted at a $160K median salary.

Clay also covers more of the GTM workflow than FullEnrich. The built-in Sequencer (powered by Smartlead) handles email outreach. Signals track job changes, website visits, and social mentions. Ads syncs enriched audiences to LinkedIn, Meta, and Google. Native CRM integrations with Salesforce and HubSpot are live.

The tradeoff is complexity. Clay runs official cohort training programs, offers 9 structured courses, and has produced 7 bootcamps and 2,500 cohort alumni just to teach people how to use it. Clay rates 4.7/5 from 185 G2 reviews, but its ease-of-use score of 8.0/10 trails FullEnrich's 9.7/10 -- a direct signal of the platform's operational complexity.

Clay's dual-currency pricing model -- Actions for platform orchestration, Data Credits for marketplace data -- is hard to predict before running enrichment at scale. In a typical 5-provider enrichment setup, Clay uses approximately 15 credits per contact at $0.07-0.08 per credit, versus FullEnrich's 1 credit per email at $0.058. Features like credit spend limits and workbook-level budgets were added to address cost overruns. For a deeper look at Clay's cost structure, see our Clay pricing breakdown.

Starting at $167/month annually with CRM integrations requiring the $446/month Growth plan, Clay is a significant investment that demands a skilled operator to justify. The Clay Experts marketplace for hiring consultants signals what the real operational cost looks like.

ZoomInfo provides the data, intelligence, and execution layer neither platform has

The core difference is architectural. FullEnrich and Clay sit on top of other companies' data. ZoomInfo builds, maintains, and verifies its own.

ZoomInfo's proprietary collection and verification system maintains the largest B2B dataset available: 500M contacts, 100M companies, 135M+ verified phone numbers, 120M direct-dial phone numbers, and 200M+ verified business email addresses.

That infrastructure includes automated ML scanning 28 million site domains daily, 200,000+ users who share data back into the system, third-party partner data covering 95 million businesses, and 300+ human researchers. In a Fortune 500 competitive RFP analyzing 25 million contacts across vendors, the independent consultant concluded that "no other competitor came even close."

The data advantage compounds through the GTM Context Graph, which processes 1.5B+ data points daily and fuses ZoomInfo's third-party intelligence with your CRM records, conversation transcripts from Chorus, and behavioral signals. The result: an intelligence layer that captures not just what happened in a deal, but why.

Your CRM records that a deal moved to Stage 3. Chorus captures that the CFO joined the call and asked about ROI. ZoomInfo's intent data shows the company is researching your competitor. The GTM Context Graph connects these signals and surfaces the insight: this deal is accelerating because executive sponsorship entered at a stage that historically correlates with closed-won outcomes.

That reasoning powers every downstream action, from the follow-up email that GTM Workspace drafts for the rep to the audience segment that GTM Studio activates for marketing.

Neither FullEnrich nor Clay can replicate this. Neither has the data infrastructure, the conversation intelligence engine, or the entity resolution and signal correlation behind the GTM Context Graph.

ZoomInfo's results in practice: Redwood Logistics used ZoomInfo Marketing, CRM Enrichment, and Workflow Tools together and cut cost-per-click by 99% while saving 25 hours per week in operational overhead. These results required verified data, native intent signals, and automated workflows from a single platform -- not the separate enrichment-then-activate steps that FullEnrich and Clay require.

ZoomInfo was also named a Leader in the Forrester Wave for Intent Data Providers, Q1 2025, receiving the highest possible scores across eight criteria -- independent validation that its intent infrastructure outperforms aggregated or third-party alternatives.

Waterfall enrichment: Three different implementations

All three platforms offer multi-vendor enrichment, but the mechanics and scope differ significantly.

FullEnrich handles the waterfall for you. Its sequence of 20+ vendors is pre-configured and optimized. You provide inputs, the waterfall runs, and you receive verified results. Simple, fast, and effective for contact data. But the waterfall covers only emails, phone numbers, and basic person/company attributes. You cannot waterfall for technographics, intent signals, or custom research questions.

Clay gives you the building blocks. You choose the providers, set the sequence, define the conditional logic, and manage credit allocation across providers. This produces more tailored results (you can waterfall for any data point across any provider) but requires expertise to build and maintain. Clay's own University has dedicated courses on building effective waterfalls. Note that Sculptor, Clay's natural-language workflow builder, cannot yet modify existing tables or support all table types -- so the learning floor is higher than the marketing copy suggests.

ZoomInfo includes waterfall enrichment across 25+ alternative data sources via GTM Studio at no additional cost. The difference: ZoomInfo's own proprietary dataset is the primary source. The waterfall supplements it with additional providers only where needed.

And because the enrichment lives inside a platform with intent data, org charts, technographics, and AI orchestration, the enriched records flow directly into plays and seller workflows without any export-import step.

For contact data coverage alone, FullEnrich's focused approach likely matches or beats any single alternative. For custom workflow flexibility, Clay offers more control. But for organizations that need enrichment as part of a larger intelligence and execution system, ZoomInfo eliminates the need to stitch together separate tools.

Intent data and signals separate intelligence from information

This is where the gap between enrichment tools and a full GTM platform becomes clear.

FullEnrich provides no intent data, no technographics, and no behavioral signals. It tells you how to reach someone. It cannot tell you whether you should.

Clay offers intent signals through third-party integrations (Demandbase, Dealfront, Identity Matrix) and custom signal logic via Claygent.

You can build workflows that monitor job changes, website visits, social mentions, and technology changes. But assembling these signals from separate providers introduces latency, inconsistency, and additional credit costs. The signals also remain disconnected from your deal history. Clay does not know which signal patterns have led to closed deals in your business.

ZoomInfo's Buyer Intent tracks signals from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings sourced monthly. Guided Intent, exclusive to ZoomInfo, identifies topics historically correlated with deal success in your specific business rather than requiring you to guess which keywords matter. WebSights resolves anonymous website traffic to companies and buying team members with direct contact info.

These signals feed into the GTM Context Graph alongside your CRM and conversation data, producing recommendations grounded in your actual win patterns. That closed-loop intelligence -- what signal combinations predict your wins, not wins in general -- is something no enrichment-only tool can approximate.

CRM integration and execution readiness

Getting data into your CRM cleanly is where enrichment turns into pipeline.

FullEnrich has a native HubSpot integration that pushes enriched contacts with deduplication and field mapping. Salesforce, Pipedrive, and Zendesk are coming soon. Non-HubSpot teams must bridge via Zapier, Make, or n8n -- a third-party dependency that adds latency and a point of failure to every enrichment workflow. Outreach tool integrations (Smartlead, Salesloft, Outreach, Gong) are also unreleased.

Clay connects natively to Salesforce and HubSpot, with a dedicated Salesforce Package that surfaces Clay workflows inside SFDC. The built-in Sequencer handles email outreach directly, and Ads syncs audiences to ad platforms. For teams already using Clay as their operational hub, the path from data to action is short. But reaching that point requires building and maintaining the workflows -- and CRM integrations require the $446/month Growth plan.

ZoomInfo integrates with Salesforce, HubSpot, Microsoft Dynamics 365, and 120+ tools across its marketplace -- all native API-to-API connections, not middleware-dependent. GTM Workspace lets sellers act on signals without leaving the platform: AI-drafted outreach, one-click CRM updates, buying group intelligence, and deal execution all happen in one place.

GTM Studio lets marketers and RevOps build plays in natural language and activate them across email, ads, direct mail, and SDR routing. For teams building custom tools, APIs and MCP expose the same intelligence to any application, including Claude and ChatGPT.

The practical difference: FullEnrich gets contact data into your hands. Clay gets enriched data into your CRM. ZoomInfo gets intelligence-driven actions into your sellers' workflow.

Pricing tells you who each platform is built for

FullEnrich is the cheapest entry point. $29/month for 500 credits, $55/month for 1,000 credits, with unlimited seats on every plan. Credits roll over (3 months on monthly, 12 months on annual). You pay only when enrichment succeeds. For a quick look at FullEnrich's full tier structure, see our FullEnrich pricing breakdown.

Clay starts at $167/month annually on the Launch plan, but the real cost depends on usage across two separate currencies.

• Actions measure platform orchestration (running enrichments, calling AI models, exporting data) and reset monthly.

• Data Credits purchase the actual data from Clay's marketplace providers and roll over within caps.

CRM integrations require the $446/month Growth plan. On top of this, variable-price AI models charge based on actual token consumption, with Clay withholding estimated credits upfront and reconciling after execution -- adding another layer of cost uncertainty. In practice, RevOps teams report that a 5-provider enrichment workflow costs approximately $0.07-0.08 per credit, with typical setups consuming 15 credits per contact. Clay charges no per-seat fees, but the implicit cost is the GTM Engineer salary ($160K median) or agency fees needed to operate it effectively.

ZoomInfo is free to start with consumption credits based on usage. Plans scale with capability -- the entry point is ZoomInfo Lite, a permanent free tier with 10 monthly export credits and access to the B2B database, Chrome extension, and website visitor tracking. A genuine way to test the data before committing.

The pricing reflects different scopes. FullEnrich prices contact enrichment. Clay prices workflow access. ZoomInfo prices a full intelligence and execution platform. The question is which problem you are solving.

The learning curve reflects each platform's philosophy

FullEnrich requires almost no learning. Upload a file, map the columns, click enrich. The Help Center covers the basics in roughly 30 articles. New accounts get 50 free credits to validate results before paying. Most teams are productive within minutes.

Clay requires significant investment. The platform offers 9 structured courses, 4 formal certifications, cohort training programs, and a Slack community of 40K+ members.

The existence of 7 external bootcamps and a dedicated Clay Experts marketplace for hiring consultants tells you what the learning curve looks like. Sculptor, Clay's natural-language workflow builder, aims to lower this barrier, but it cannot yet modify existing tables or support all table types.

ZoomInfo falls in the middle. The platform is broad, but ZoomInfo redesigned its onboarding from 30 to 90 days with structured planning, implementation, and adoption phases, producing a 25% improvement in satisfaction scores. ZoomInfo University offers role-specific learning paths, and GTM Workspace is designed so sellers can act on AI-generated recommendations immediately.

Security and compliance

All three platforms hold baseline enterprise security certifications.

FullEnrich achieved SOC 2 Type II in September 2025 and is GDPR and CCPA compliant with a published DPA. One architectural advantage: FullEnrich does not maintain a contact database. It queries providers in real time and deletes enrichment data after 3 months, minimizing stored PII exposure.

Clay is SOC 2 Type II, GDPR, CCPA, and ISO 27001 compliant, with audit trails available for enterprise accounts.

ZoomInfo holds the broadest certification stack: ISO 27001, ISO 27701, SOC 2 Type II, TRUSTe GDPR Practices, and TRUSTe CCPA Practices, all renewed annually. For RevOps teams evaluating enterprise vendor security posture -- where mismatched certifications create procurement blockers -- ZoomInfo's compliance infrastructure is the most comprehensive of the three.

• You are comfortable investing time in learning a complex platform

• You need workflow automation alongside enrichment, not just contact data

Explore Clay with a 14-day free trial and see what a custom workflow can do for your pipeline.

Choose ZoomInfo if:

• You want proprietary, verified data rather than aggregated third-party sources

• Knowing which accounts are in-market matters as much as having their contact info

• You need data, intelligence, and execution in one platform instead of assembling separate tools

• Your organization is ready for AI that understands deal context, not just AI that formats data

• You want integration with your CRM, outreach tools, and ad platforms without building custom workflows

• You want to consolidate your enrichment vendor, intent tool, and workflow platform onto one contract

Start with ZoomInfo Lite for free or request a full trial to see the difference proprietary data and contextual intelligence make.

FullEnrich solves the contact data gap at the lowest cost and lowest complexity. Clay gives technical teams a workspace to build any GTM workflow they can imagine.

ZoomInfo provides the foundation underneath both problems: verified data you can trust, intelligence that explains why deals move, and access lanes that deliver that intelligence into every tool and workflow your team uses. The question is not which platform has the most features. It is whether you need a point solution, a builder tool, or a platform that turns data into decisions.

If your GTM motion needs more than enrichment workflows or contact lookups, see how ZoomInfo's all-in-one AI GTM Platform works -- data, intent, and execution in one place.

FullEnrich vs. Clay: Frequently Asked Questions

Is FullEnrich better than Clay?

It depends on your use case. FullEnrich is better for straightforward contact enrichment at low cost -- it does one thing simply and well. Clay is better for building custom multi-step GTM workflows with conditional logic and AI research. If your only problem is missing contact data, FullEnrich wins on simplicity and price. If you need enrichment as one step in a larger automated workflow, Clay wins on flexibility. Neither provides proprietary data, intent signals, or deal-context AI -- that gap is where ZoomInfo enters the conversation.

What is the difference between FullEnrich and Clay?

FullEnrich is a single-purpose waterfall enrichment tool: you input names and companies, it returns verified emails and phone numbers by querying 20+ vendors in sequence. Clay is a GTM workflow builder that uses enrichment as one step in multi-step automations -- you can enrich contacts, run AI research, score based on custom logic, and push results to your CRM in a single table. FullEnrich is simpler, cheaper, and faster to start. Clay is more powerful, more complex, and requires a skilled operator to get full value.

Is ZoomInfo an alternative to FullEnrich and Clay?

Yes, but the scope is different. ZoomInfo is an all-in-one AI GTM Platform with proprietary data (500M contacts, 100M companies), native intent signals (Buyer Intent, Guided Intent, WebSights), conversation intelligence (Chorus), and workflow execution (GTM Studio, GTM Workspace). FullEnrich and Clay are enrichment tools that aggregate third-party data. ZoomInfo provides the foundation both tools try to replicate from aggregated sources -- with first-party verification, closed-loop deal intelligence, and a single platform instead of assembled point solutions. For a direct comparison, see Clay vs. ZoomInfo.

How much does FullEnrich cost compared to Clay?

FullEnrich starts at $29/month for 500 credits (1 credit per email at $0.058/email, 10 credits per phone at $0.58/mobile). Clay starts at $167/month annually (Launch plan) with a dual-currency model (Actions + Data Credits). CRM integrations on Clay require the $446/month Growth plan. In a typical 5-provider setup, Clay costs approximately $0.07-0.08 per credit and uses around 15 credits per contact enrichment -- roughly $1.00-1.20 per contact in enrichment credits alone, before platform and Action costs. Full TCO on Clay also includes the implicit cost of a GTM Engineer ($160K median salary) or agency fees to operate it effectively.

Does FullEnrich integrate with Salesforce?

Not natively yet. As of 2026, FullEnrich's Salesforce integration is listed as "Coming Soon." Only HubSpot is live natively. Non-HubSpot teams must use Zapier or Make as middleware, which adds a third-party dependency and additional latency to every enrichment workflow. Clay has native Salesforce and HubSpot integrations, though the Salesforce Package requires the Growth plan ($446/month).

Which is better for a RevOps team: FullEnrich, Clay, or ZoomInfo?

For RevOps teams whose primary need is contact enrichment at low cost, FullEnrich is the most efficient option. For teams building custom GTM workflows, Clay provides the most flexibility -- but it requires a dedicated operator and carries real implementation overhead. For RevOps teams evaluating vendor consolidation (replacing separate enrichment, intent, and workflow tools with one platform), ZoomInfo provides the integrated solution: verified data, native intent signals, workflow automation via GTM Studio, and 120+ native CRM integrations that eliminate middleware dependencies.
