10 Best Clay Agencies in 2026: Pricing, Proof and Fit

A Clay agency designs, builds and often runs go to market systems inside Clay: account research, enrichment waterfalls, scoring, signal tracking, CRM sync and the outreach that sits on top. Some Clay agencies hand you a working system and train your team to run it. Others use Clay as the engine behind a managed outbound or paid program they operate for you. This guide ranks the 10 Clay agencies buyers shortlist most often in 2026, with what each firm sells, who it fits, how it prices and the proof each firm publishes about itself.

I run frontBrick, so we are first on this list, and I want that to be clear before you read on. Everything about the other nine comes from their own websites, checked on 9 November 2026. When a firm publishes a number, I attribute it to them. When a firm does not publish a price, I say so instead of guessing. None of the other agencies are linked, because this is a buyer's guide, not a link exchange. If you want to verify partner status, the official Clay Solutions Partner Directory is the place to do it.

One more note on scope. This list is about agencies whose Clay work is a real service line: implementation, GTM engineering, Clay powered outbound or Clay based CRM data work. It is not a list of data platforms, freelance marketplaces or general marketing agencies that happen to use Clay somewhere in the stack.

Key takeaways

The 10 best Clay agencies at a glance

How we chose these Clay agencies

I started from the firms AI answer engines and Google results name for prompts like "best Clay agency to build our outbound workflows," then cross checked them against the official partner directory and each firm's own site. Every agency here had to show three things on its own website:

1. Clay as a named service. A Clay page, a Clay service line or Clay workflows described in detail. A logo in a tools strip was not enough.
2. A clear delivery model. Either they build and hand over, or they run the program. Both are valid. Mixing them up is how buyers end up disappointed.
3. Evidence I could attribute. Case study numbers, client counts or partner status the firm publishes itself.

I left out firms that no longer fit the category. ColdIQ now positions itself as a B2B data platform with an agent and credit plans, and its agency team now operates as Frontal, which is on this list. Paid media specialists that use Clay in passing were also left out, because their core service is advertising, not Clay engineering.

1. frontBrick

Best for: B2B teams that want a working Clay system built by senior GTM engineers, documented, and handed to their own team, with managed outbound or ABM added only when it helps.

frontBrick is a boutique Clay consulting agency. We are listed in the official Clay Solutions Partner Directory as an Advanced Artisan, and you work directly with senior go to market engineers who have sales and marketing backgrounds. The people who shape the strategy also build the tables, test the workflow and explain it to your team.

What we build in Clay:

• Market mapping and account research. ICP definition, TAM mapping and Claygent research that turns specific buyer questions into account context.
• Data foundations. Enrichment waterfalls, contact validation, field standards and de duplication, synced to HubSpot, Salesforce or your CRM with clear update rules. Our guide to B2B data enrichment shows how we structure that work.
• Signals and routing. Hiring, job changes, company news and engagement layered on top of fit, so reps get the account, the reason and the next play.
• Agentic GTM systems. Agents that research accounts, interpret signals and recommend or carry out approved actions, with defined evidence, allowed tools and review points.
• Activation. Outreach prep in Instantly, Smartlead, lemlist or HeyReach, supported ad audiences and CRM updates from the same account intelligence.

How we price it. Clay implementation is a custom project, scoped around the workflows, integrations and agent behavior you need. If you want a broader build, our fractional GTM engineer engagement runs for three months in your own tools and ends with a documented handover. If you also want us to run the program, multichannel outbound starts at $4,500 per month with tools included, and ABM starts at $7,000 per month. All of it is on our pricing page.

Why we are first. Most Clay buyers do not need more columns. They need someone who can say which columns matter, which accounts deserve the expensive research and what the rep should do with the answer. That is the gap between a table builder and a GTM engineer, and it is where we spend our time.

Watch out for: We are a boutique team. If you need dozens of people running channels across several regions at once, a larger managed partner may suit you better.

2. Frontal

Best for: B2B tech companies from Series A onward that want one partner accountable for pipeline across outbound, ABM, paid media and content.

Frontal describes itself as a GTM partner responsible for qualified pipeline across every channel. Its site states that ColdIQ Agency became Frontal in 2026 with the same operators and a new name, and that case studies published under the ColdIQ Agency name are the team's work. Services listed include GTM services (outbound, signal tracking and workflows run inside your CRM and Slack), account based marketing, paid media on LinkedIn and Google, and content engineering.

Proof it publishes. Frontal reports working with 300+ companies. Its homepage cites $7.83M in qualified pipeline in 10 months in its AirOps case study, $300K+ pipeline in 9 months for Teikametrics and 20 opportunities in the first 20 days for Playbook.

Pricing. Not published on the homepage.

Watch out for: Frontal is a broad managed program. If you only want a Clay build your team will own, confirm that scope is on offer before the first call.

3. Growth Engine X

Best for: Companies with $1M+ in revenue that want a Clay powered cold email machine run at serious volume.

Growth Engine X focuses on B2B lead generation through cold email, with Clay and Claygent in the research layer. Its site says it sends 8M+ cold emails per month for clients and reports 62K+ positive responses in 2025. It also states that all work is transferable to the client, including domains, inboxes, Clay tables and lists, which is worth asking every agency about.

Pricing. Not published. The firm offers a free test campaign before you commit.

Watch out for: This is a volume model. If your total addressable market is a few hundred accounts, the mechanics that make high volume cold email work matter less than research depth and timing, so test fit carefully.

4. SalesCaptain

Best for: B2B, SaaS and service companies that want Clay prospecting tied directly to outbound campaigns the agency runs.

SalesCaptain has a dedicated Clay agency page and describes building custom Clay and AI agent workflows tailored to each client's industry. Its outbound offer combines target niches with intent, funding and revenue data, then runs LinkedIn, email and text campaigns, with HubSpot, Salesforce and other CRM integrations.

Proof it publishes. One case study on its homepage reports 120+ booked meetings and $1.5M in new revenue. A client testimonial on the site credits the team with over $320,000 in new revenue in 2022.

Pricing. SalesCaptain does not list its own price, but its Clay agency page reports that monthly retainers in the category range from roughly $3,000 to $15,000 depending on complexity and scope. That is a useful benchmark for any proposal.

Watch out for: The strength is campaign execution. If you want deep CRM architecture or agents that act on inbound leads, ask for examples of that specific work.

5. Understory

Best for: Growth stage and enterprise B2B SaaS companies that want paid, outbound, content and RevOps run by one team.

Understory calls itself an allbound B2B growth agency based in Miami. Clay sits underneath its GTM engineering practice: signals such as a past champion changing jobs, waterfall enrichment in Clay with every email double validated, and leads routed into HubSpot, Salesforce or Attio. Its homepage describes plays going live by week four and fortnightly optimization.

Proof it publishes. Understory says it has served 150+ companies, including Worldpay and Expensify, and reports $100M+ in revenue generated for clients. It cites $3,652,185 in pipeline at 7.2x ad spend for Doppel's paid search program.

Pricing. Not published.

Watch out for: Allbound means you are buying several channels at once. If budget only covers a Clay build, say so early.

6. RevPartners

Best for: Companies running on HubSpot that want Clay implementation and RevOps from the same partner.

RevPartners positions itself as RevOps plus GTM engineering for businesses on HubSpot and Clay. Its Clay implementation service covers the foundational build and playbooks, and its wider offer includes CRM operations and a Revenue Performance Model for measuring revenue across the customer journey.

Proof it publishes. RevPartners states it is the only business in the world to hold Elite accreditations with both HubSpot and Clay.

Pricing. Not published.

Watch out for: The center of gravity is HubSpot. If you run Salesforce or a lighter CRM such as Attio, check how much of their playbook transfers.

7. Sculpted

Best for: B2B software teams whose most urgent problem is a CRM nobody trusts.

Sculpted is a Clay specialist for CRM data. Its core offer is a 30 day CRM clean up sprint: define the ideal record, rebuild enrichment in Clay mapped to your fields, validate accuracy manually on 20+ sample records per property before rollout, then import into HubSpot or Salesforce. Every workflow is built in the client's own Clay account, with documentation in Notion and Loom walkthroughs.

Proof it publishes. A client quoted on Sculpted's site says contact discovery cost fell from $4.50 to about $1 per account and direct line coverage rose to 53%.

Pricing. Sculpted says it presents a fixed price investment after scoping. The amount is not published.

Watch out for: This is a focused data engagement. Outreach and signal plays come after, either with your team or another partner.

8. FullFunnel

Best for: Teams that want embedded senior operators and someone to administer Clay on an ongoing basis.

FullFunnel describes managed support and applied AI for B2B GTM teams. Its menu includes strategy, engineering, audits, pilots, data operations and Clay administration, plus a Clay data engine, n8n programs and HubSpot agent programs.

Proof it publishes. FullFunnel reports serving 1,000+ B2B organizations and 12+ years in production GTM.

Pricing. Not published.

Watch out for: Ongoing administration is useful, but make sure the system and documentation stay yours if the engagement ends.

9. Go Nimbly

Best for: Mid market and enterprise B2B SaaS companies that want Clay inside a larger RevOps architecture.

Go Nimbly is a RevOps consultancy with a dedicated Clay services line. Its positioning is RevOps built for speed and scale, so Clay tends to arrive as one part of a systems program alongside CRM, process and reporting work.

Proof it publishes. Its homepage highlights the funding stages of clients it has worked with rather than campaign results.

Pricing. Not published.

Watch out for: Consultancies built for larger transformations can be more than a seed stage team needs. Ask for a scoped first workflow.

10. demandDrive

Best for: Teams that want Clay services and extra sales development capacity from one vendor.

demandDrive presents itself as a GTM partner across sales services, growth marketing and RevOps and GTM engineering, with Clay services listed on its site. The combination is useful when you need both the system and people to work the leads it produces.

Proof it publishes. Its homepage cites $16M in pipeline generated in one case study and $136M in new converted opportunities in another.

Pricing. Not published.

Watch out for: Ask which team owns the Clay build and whether it is the same team that runs your SDR program.

Clay agency vs freelancer vs in house GTM engineer

How much does a Clay agency cost?

Most Clay agencies do not publish prices, and the ones that do rarely mean the same thing by the number. Here is how pricing usually breaks down:

• Custom implementation projects. A focused enrichment and routing build is priced very differently from a multi system build with account agents, CRM sync and several activation channels. Ask for deliverables and acceptance criteria in writing.
• Fixed price sprints. Sculpted, for example, scopes a 30 day CRM sprint and presents a fixed price after the diagnostic.
• Monthly retainers. SalesCaptain reports that retainers in the category range from roughly $3,000 to $15,000 per month. Managed outbound sits in that range or above, depending on channels.
• Clay and data costs on top. Your Clay plan and data credits are usually separate from the agency fee. Check current plans on Clay's pricing page and ask the agency for a credit estimate based on a sample run, not a guess.

At frontBrick, Clay builds are custom projects, outbound starts at $4,500 per month with tools included, ABM starts at $7,000 per month, and a $500 Power Hour gives you a 60 minute strategy session with a written plan if you want a second opinion before hiring anyone.

What a good Clay agency delivers in the first 90 days

If an agency cannot show you a sample table with real credit numbers by week five, the build is probably not as far along as the status calls suggest.

How to choose the right Clay agency

Use these questions on every first call. Two vague answers is a good reason to move on.

1. Who will build my tables? Meet the engineer, not just the account lead.
2. What happens outside outbound? Inbound routing, CRM hygiene and account monitoring are where Clay often pays back first.
3. How do you control credit spend? Look for answers like "filter for fit before expensive research" and "stop the waterfall when we have the answer."
4. What do we own at the end? Tables, workflows, domains, inboxes and documentation should all be yours.
5. How do you check AI output? Agents need defined evidence, allowed actions and human review points.
6. Can you verify partner status? Look the firm up in the official partner directory. If your team wants to learn the basics first, Clay University is free and good preparation for the call.

Sales leaders are under real pressure to do more with less. Salesforce's State of Sales research tracks how much rep time still goes to work other than selling, and that is exactly the time a well built Clay system should give back. For a wider view on how sales teams are changing, Harvard Business Review's sales coverage is a useful reading list.

When you do not need a Clay agency

Not every team should hire one. Skip the agency if:

• You have fewer than a few hundred target accounts and a rep who already researches them well.
• Nobody on your team will own the system after launch. A system without an owner decays in weeks.
• Your real problem is the offer or the message, not the data. Clay makes a good offer reach the right people faster. It does not fix a weak one.

If you are still unsure, look at the tools first. Our list of AI sales tools we use shows where Clay fits next to enrichment, sequencing and research tools.

FAQ

What is a Clay agency?

A Clay agency is a firm that designs and implements go to market systems in Clay for account research, data enrichment, scoring, automation and activation. Some build and hand over the system. Others use Clay to run outbound, ABM or paid programs on your behalf.

What is the difference between a Clay agency and a claygency?

There is no real difference. "Claygency" is an informal name for a Clay agency that has spread through the Clay community. What matters is whether the firm builds systems your team owns or runs campaigns for you.

How much does a Clay agency cost in 2026?

Most firms price custom projects and do not publish rates. SalesCaptain reports that monthly retainers in the category range from roughly $3,000 to $15,000. Clay plans and data credits are usually extra, so ask for a credit estimate on a sample run.

How do I check if a Clay agency is a certified partner?

Search for the firm in the official Clay Solutions Partner Directory. A listing is one check. You should still meet the engineer who will do the work and ask to see a relevant workflow.

Should I hire a Clay agency or a GTM engineer?

Hire an in house GTM engineer when you have a steady backlog and a team ready to manage the role. Choose a Clay agency or a fractional GTM engineer when you need a defined system built quickly and handed over with documentation.

How long does a Clay implementation take?

A focused workflow can be live in a few weeks. A multi system build with CRM sync, signals and agents usually needs one to three months, including validation and handover. The timeline depends on data access, integrations and review cycles.

Can a Clay agency also run my outbound?

Many can. Growth Engine X, SalesCaptain, Understory and Frontal run campaigns, and frontBrick offers managed outbound from $4,500 per month alongside Clay builds. Decide first whether you want to own the system or rent the outcome.

What should be in a Clay agency contract?

Deliverables and acceptance criteria, who pays for Clay and data credits, ownership of tables, workflows, domains and lists, documentation and training, and what ongoing support costs after launch.
