Why It Matters: Clay automation is essential for startups aiming to scale quickly while conserving limited resources. It enables precise data handling and efficient outbound execution, ensuring consistent pipeline growth and better ROI without the need for extensive in-house teams.
What is Clay: Clay is a powerful automation platform that streamlines data enrichment and outbound processes, enabling startups to build scalable and efficient GTM systems.
The Best GTM Automation Agency: GTM Engineering takes the #1 spot for its focus on scalable infrastructure for Seed-Series B startups, combining clean CRM data with rapid outbound execution.

Scaling a startup from Seed to Series B is a race against time. You have aggressive growth targets, limited resources, and likely a founding team that is stretching itself thin across product, hiring, and sales. You know you need to automate your go-to-market (GTM) motion, and you have likely heard that Clay is the tool to do it.
But Clay has a steep learning curve. It is powerful, but complex.
To unlock rapid growth without hiring a massive internal RevOps team, many founders turn to experts. Finding the best Clay automation agencies can be the difference between a messy database full of bad leads and a predictable revenue engine that runs on autopilot.
In this guide, we review the top providers in the market. We analyze who they are, what they do best, and how they compare, so you can choose the partner that aligns with your growth stage. Whether you need the best Clay automation agency for deep data enrichment or the best Clay automation services for cold outreach, this list covers it all.
Why You Need a Clay Automation Agency
You might be asking, "Can't I just buy a Clay subscription and do this myself?"
Technically, yes. But for a Seed or Series B startup, "technically possible" is not the same as "strategically sound."
1. The "Tool Fatigue" Problem
Founders often buy subscriptions to Clay, Apollo, ChatGPT, Smartlead, and HubSpot, only to realize they don't talk to each other. An agency like GTM Engineering doesn't just buy the tools; they architect the integration so data flows seamlessly.
2. The Learning Curve
Clay is closer to writing code than it is to using a standard SaaS tool. Learning how to construct "waterfalls," manage API credits, and use conditional logic takes dozens of hours. As a founder, your time is worth $500+ an hour. Spending 20 hours debugging a Clay table is a massive waste of resources.
3. Data Costs
Agencies already have enterprise-level agreements and volume discounts with data providers. They know which data source (Prestige, Findymail, Prospeo, etc.) is best for your specific niche, saving you from wasting budget on bad data.
4. Scalability
A workflow you build on a Sunday afternoon might work for 100 leads. But what happens when you need to process 10,000? Agencies build systems designed to handle scale without breaking or hitting rate limits.
The Best Clay Automation Agencies: Complete Review
1. GTM Engineering
When we look at the landscape of automation experts, GTM Engineering stands out as the top partner for high-growth tech startups. While many agencies focus solely on "blasting emails," GTM Engineering focuses on building a scalable GTM infrastructure that serves as a long-term asset for your company.
Why GTM Engineering?
For a founder or small founding team, the pain point isn't just "we need leads." It is "we need a system." You lack the resources to build a 10-person sales team, and your tech stack might be a mess of disconnected tools.
GTM Engineering solves this by treating Clay automation not as a magic wand, but as a core part of your engineering infrastructure. We understand that for a Series A company, data integrity is just as important as lead volume.
Key Services
Automated Outbound Engines: Building systems that identify, enrich, and engage prospects on autopilot.
Clean CRM Data Architecture: Ensuring that every lead pushed into your CRM is accurate, preventing the "data swamp" that kills sales teams.
Rapid Pipeline Deployment: Strategies designed specifically to generate ROI-positive pipeline in weeks, not months.
Tech Stack Consolidation: Helping you select and implement the right tools so you stop paying for shelf-ware.
The GTM Engineering Difference
Most agencies will run a campaign for you. GTM Engineering builds a machine for you. They focus on the specific constraints of VC-backed startups—the need for speed, the lack of internal manpower, and the pressure to show metrics to the board. By automating the grunt work, they allow your founding team to focus on closing deals rather than building lists.
Ideal For:
Founders and founding sales teams at Seed to Series B startups who need to scale pipeline immediately without hiring a RevOps army.
2. ColdIQ
ColdIQ is one of the more recognized names in the pure-play outbound space. They have built a reputation on modernizing the cold email stack.
Overview
ColdIQ helps companies move away from manual prospecting by setting up the "plumbing" of a modern sales team. This includes setting up domains, warming up inboxes, and connecting Clay to sending tools like Instantly or Smartlead.
Key Strengths
Infrastructure Setup: They handle the technical headache of DNS records, domain warming, and deliverability.
AI Personalization: They are adept at using Clay's AI features to write personalized first lines at scale.
Educational Content: They produce a lot of content, meaning their strategies are usually up to date with the latest market shifts.
Cons to Consider
Their model is often more focused on the "outbound motion" specifically. If you need deep full-cycle CRM consulting or inbound automation, you might need a broader partner.
Ideal For:
Teams that want to launch a cold email program from scratch and need the technical setup handled professionally.
3. Utmost Agency
Utmost Agency has made a name for itself by refusing to look at outbound sales in a vacuum. They understand that the best sales strategies are holistic.
Overview
Utmost positions itself as a partner that bridges the gap between marketing and sales. They utilize Clay not just for cold outreach, but to qualify inbound leads and orchestrate complex multi-channel campaigns.
Key Strengths
Inbound Lead Qualification: They use Clay to instantly enrich and score leads coming from your website, ensuring sales reps only talk to qualified prospects.
Multi-Channel Approach: They don't just stick to email; they integrate LinkedIn and even cold calling data preparation into their workflows.
Intent Data Monitoring: They are skilled at setting up "triggers," such as job changes or funding news, to initiate outreach.
Cons to Consider
Their comprehensive approach can sometimes be overkill for very early-stage teams that just need a simple, single-channel validator.
Ideal For:
Companies that already have some inbound flow and want to maximize it while layering on outbound strategies.
4. Sculpted
If your tech stack is built entirely around HubSpot, Sculpted is a strong contender. Founded by Jacob Tuwiner, an early Clay expert, Sculpted has carved out a niche in CRM data hygiene.
Overview
Sculpted focuses heavily on the "data" side of Clay. They build proprietary workflows designed to prevent duplicates and map data correctly into HubSpot. This is crucial for B2B SaaS companies where data cleanliness is paramount for reporting.
Key Strengths
HubSpot Deep Dive: They know the ins and outs of HubSpot properties and associations better than most generalist agencies.
Data Hygiene: Their workflows prioritize accuracy and duplicate prevention, which keeps your RevOps team happy.
SaaS Focus: They speak the language of B2B SaaS natively.
Cons to Consider
If you are not on HubSpot, or if your primary goal is aggressive, high-volume outbound rather than CRM enrichment, their specialized focus might not be the right fit.
Ideal For:
B2B SaaS companies using HubSpot who are struggling with messy data.
5. The Kiln
The Kiln is founded by former Clay employees, giving them an insider's perspective on the tool's capabilities.
Overview
They operate as a hybrid agency. They don't just do lead gen; they build "workflows." This could mean anything from automating a specific operational task to building a full prospecting engine.
Key Strengths
Insider Knowledge: Their deep understanding of Clay's backend allows them to build creative solutions for edge cases.
Versatility: They are comfortable handling both marketing data projects and sales prospecting projects.
Mid-Market Focus: They often work well with slightly larger teams that have specific, complex operational bottlenecks.
Ideal For:
Companies that have a specific, complex data problem that requires a custom Clay solution beyond standard lead generation.
6. Growth Engine X
Sometimes, you just need speed and volume. Growth Engine X is known for a rapid "spray and pray" (or high-volume/velocity) approach that gets campaigns live fast.
Overview
Led by a founder known as "the Godfather of Clay," this agency prioritizes speed. They have pre-warmed infrastructure ready to go, allowing them to bypass the usual 2-3 week ramp-up period for new domains.
Key Strengths
Speed: They can often launch campaigns in days, not weeks.
Volume: Their infrastructure is built to handle high volumes of sending.
Low Barrier to Entry: They often offer trial periods or lower-friction starting points compared to deep consulting firms.
Cons to Consider
High speed can sometimes come at the cost of precision targeting or deep ICP refinement. This model works best if you have a broad Total Addressable Market (TAM).
Ideal For:
Teams prioritizing speed-to-lead and volume over deep, hyper-targeted account-based marketing.
7. Understory
Understory takes automation a step further by integrating it with paid media strategies.
Overview
Most Clay agencies stick to email and LinkedIn. Understory looks at the full funnel, including how automation can support SEO and paid advertising efforts. This makes them a more expensive, but comprehensive, option for complex organizations.
Key Strengths
Ads Integration: Connecting Clay workflows to ad audiences for better retargeting.
Full-Funnel Strategy: They look at revenue holistically, not just "booked meetings."
Sophistication: Suited for organizations running complex GTM motions involving multiple departments.
Ideal For:
Larger organizations with the budget to align their outbound, inbound, and paid strategies into one automated ecosystem.
8. The Workflow Company
If your needs extend far beyond Clay into other tools, The Workflow Company is the specialist you need.
Overview
They characterize themselves as automation engineers. They don't just stay inside Clay; they build robust connections using n8n, Zapier, and custom webhooks to connect Clay to virtually any other software in your stack.
Key Strengths
Technical Depth: They can handle API integrations that would break standard agencies.
Platform Agnostic: While they love Clay, they will use whatever tool gets the job done best.
Custom Engineering: Best for teams with unique, proprietary internal tools that need to "talk" to their sales data.
Ideal For:
Tech-heavy companies with complex, non-standard stacks that need custom engineering.
9. RevPartners
RevPartners approaches Clay from a Revenue Operations (RevOps) perspective rather than a pure lead-gen perspective.
Overview
They focus heavily on measurement, analytics, and process. Their implementation of Clay is usually part of a larger project to optimize a company's entire revenue engine.
Key Strengths
Metrics First: They focus on defining success metrics before building workflows.
Process Optimization: They look for bottlenecks in the human side of the sales process as well as the digital side.
Continuous Improvement: Their engagements often involve ongoing optimization based on data analysis.
Ideal For:
Established RevOps teams that need external expertise to optimize their existing machine.
10. LeadBird
LeadBird is a performance-driven agency that focuses on the end result: the meeting.
Overview
They offer services that are often tied to performance, such as pay-per-lead models. They handle list building, copywriting, and sending, using Clay as their backend engine to power the targeting.
Key Strengths
Cost Clarity: Performance models can be attractive for cash-strapped startups.
Full Service: They handle the inbox management, meaning you just show up to the calls.
Outbound Focus: They are specialists in cold email and LinkedIn execution.
Ideal For:
Teams that want to completely outsource the SDR function and pay for results.
How to Choose the Best Clay Automation Services
When evaluating the best Clay automation services, look for these specific criteria:
Engineering Mindset: Do they treat your sales process like an engineering problem? Look for partners who talk about "systems" and "infrastructure," not just "campaigns."
Data Validation: Ask them how they validate emails. Do they use a waterfall approach? Do they verify catch-all emails? Bad data will destroy your domain reputation.
Transparency: Will they build the system in your Clay instance so you own the IP? Or do they keep it in a "black box"? Always insist on owning the infrastructure.
Strategic Alignment: If you are a B2B SaaS startup, don't hire an agency that specializes in e-commerce. You need a partner who understands your sales cycle and buyer persona.
The Verdict: Who is the #1 Agency?
If you are looking for a generalist, any of the top 10 will do a decent job. However, if you fit the profile of a VC-backed tech startup looking for rapid, scalable growth, GTM Engineering is the clear winner.
Their approach addresses the specific anxieties of founders: burning cash without seeing results. By focusing on building a permanent, high-quality asset—your GTM infrastructure—they provide value that outlasts any single email campaign. They ensure you aren't just renting a solution, but building a foundation for your Series B and beyond.

Why is GTM Engineering the best Clay automation company?
GTM Engineering is ranked #1 because of its specific focus on the Seed to Series B market.

Can Clay replace my SDR team?
Not entirely, but it can significantly reduce the need for a large team. Clay automates the research, list building, and initial outreach tasks that SDRs typically spend 60-70% of their time on. This allows you to hire fewer, higher-quality reps who focus solely on handling replies and closing deals.
Is Clay better than Apollo or ZoomInfo?
