11 Best Clay Experts for Outbound Sales Automation and GTM Engineering

Most Clay users waste hours scrolling through the “Clay Experts” page, hoping to find someone who actually knows what they’re doing.

But the page offers little to go on. No real case studies, no breakdown of how they use Clay, and barely any insight into what they’ve built. 

You’re left guessing: Is this person just good at making Loom videos, or can they actually build a system that books meetings and drives revenue?

There is also the fact that not all Clay experts are necessarily listed there. Or maybe you find the ones there expensive and are looking for alternative options. 

That’s exactly why we wrote this list.

We’ve cherry-picked 10 of the most effective Clay-powered outreach and data enrichment experts and we’re giving you the details you won’t find anywhere else. 

For each expert, we show:

• What kinds of systems they build
• Which tools they combine with Clay
• What results they’ve driven for clients
• How to contact or hire them directly

Whether you’re a founder who wants to scale outbound, a marketing team trying to enrich leads faster, or a sales pro looking to book more demos, this list gives you the real deal.

Let’s get started.

Note: Struggling to connect with decision-makers in your target market?

We’ll run a completely done-for-you outbound campaign and automate your sales prospecting process to generate a pipeline with prospects ready to engage on autopilot.

11 Best Clay experts for data enrichment and outreach

Here are the top Clay experts you should consider. 

Keep in mind that this is not a list where we are comparing their services or claiming that we are better than they are. These are actually competitors and good friends we see in the trenches and are quite cordial with. 

You can be sure that everyone on this list can help you design GTM workflows with Clay and help boost your sales. 

1. Andrew van Rossenberg and Colin Bakker (Utmost Agency)

LinkedIn: Andrew van Rossenberg

LinkedIn: Colin Bakker

Yeah, that’s us. And we believe we’re the best Clay experts you can hire today. 

So, we’re Andrew and Colin, founders of Utmost Agency. 

We help startups and B2B companies build sales systems that run on autopilot. No fluff, just clean, efficient outbound and inbound sales pipelines that do what they’re supposed to: get leads, book sales appointments or close deals for you.

We’ve spent years testing what works and what doesn’t. 

Our experience being former salespeople in the trenches doing the heavy manual work and freelancing has taught us that most sales and RevOps teams burn out trying to manage too many tools and too many tasks manually. 

We are sure that’s probably what brought you here. So we got together and built Utmost Agency to simplify the entire process. 

We built a system that uses Clay as the brain and connects to tools like Instantly.ai, PandaMatch, Phantombuster, n8n.io, FullEnrich, Apify, TryTelescope, Periodix, ChatGPT, Claude.ai, and more to handle the rest.

With this, we design full-stack sales machines that:

• Find your ideal leads
• Enrich them with smart data
• Reach out across multiple channels
• Track every response and action
• Feed qualified leads directly to your calendar or CRM

Our Clay and outreach expertise + How our sales engine works

We use a 4-step sales system engineered for precision, automation, and conversion with Clay and Claygent at the heart of it all.

Step 1: ICP precision, TAM (total addressable market) identification, and smart targeting

For us, sales success starts with targeting the right people. 

So, our process begins with stakeholder interviews to deeply understand your product, your market, and your customers’ pain points. 

From there, we build a centralized Clay workspace and make it the command center of your outbound and inbound sales strategy.

You get:

• Smart ICP frameworks based on your own customer data
• Data ingestion from CRM, website, and LinkedIn into Clay. Basically, we connect your existing data into Clay to learn from it and start from there. It also helps align outbound with inbound from the start. 
• Contextual ICP expansion using PandaMatch.io to find look-alike audiences from your best customers to win you more deals. 
• TAM identification based on data you gathered from defining your ICP, like what industry they’re in, company size, location, job titles, etc. 
• Deep filtering logic based on real-world behaviors

Unlike most agencies that rely on generic databases like Apollo, ZoomInfo, or Lusha, we choose the data source based on your ICP and business industry or niche. Then we build custom enrichment layers that identify not just who to target, but why, when, and how.

Step 2: Multi-channel outreach automation

We orchestrate a multi-channel outreach system.

You get:

• Personalized messages crafted using Claygent + LLM (Claude or ChatGPT) based on the enriched lead data in our Clay table, along with intent data 
• Native push into Instantly.ai for email outreach
• LinkedIn automation via Periodix
• Built-in deliverability tracking and fallback channels (e.g., we send a LinkedIn message if we detect the target is using Outlook)

Every campaign is monitored, refined, and auto-synced. Each outreach channel speaks to the other. 

Bonus: We also equip your internal sales team with enriched data and cold calling openers that tie back to real-time campaign intelligence so they can pick up the phone and close deals from conversations we started.

Here is what the workflow for the first two steps look like:

Step 3: Intent data automation in real-time

While most agencies rely on static buyer lists, we take things the extra mile and run systems that watch the market and act when buyers need your solution, moving towards needing solutions or showing signs for it.

Basically, here, we build a system combining RSS feeds, n8n, Apify, PhantomBuster, and Clay at the center. 

RSS feeds, Apify, and PhantomBuster serve to capture real-time intent data based on parameters we define for buying signals and intent data about your business and product. 

They then push the data into Clay, which enriches the data and reaches out automatically. 

Here, you get:

• Live job scraping (e.g., SDR roles = need for sales automation)
• Funding round alerts via Crunchbase + TechCrunch
• Competitor acquisition tracking
• News and signal-based workflows for niche markets

We capture these signals via PhantomBuster, Apify, RSS feeds, and n8n, we push them into Clay, enrich automatically, and then instantly trigger into multi-channel outreach.

For example, if we have a client who sells furnishing solutions, when a real estate developer announces new property acquisitions, that’s a signal that they’re going to be needing furnishing solutions. 

So, we scrape the news, identify decision-makers, and send an AI-personalized pitch before any competitors get wind of the opportunity.

Keep in mind, we go further than these tools. It’s all dependent on your business, target customers, and the unique strategies we uncover for your market. 

Here is what the workflow looks like:

Step 4: Inbound qualification and sales handoff (inbound-led outbound sales)

Once outbound starts working, we layer in inbound. 

Here, the idea is simple. Manual inbound lead qualification takes time, it’s messy, and usually, there are disagreements between what marketing believes is a qualified lead and what sales reps believe it should be. 

There are actually a lot of issues here that make businesses lose deals. So, we help automate this for you as well. 

We connect form submissions, demo requests, key page content consumption, and downloads directly from your website into Clay. Same for interest from your social media posts. 

This happens through webhooks, n8n, Clay, and the tech stack on your website. 

Every inbound lead is:

• Enriched using the same robust outbound logic
• Qualified instantly via a custom scoring model (we do this together with you or your sales team)
• Routed to sales with personalized insights and contact strategies

We plug your inbound traffic into an improved version of the same Clay table. You get faster lead response times, zero manual qualification, and an always-on pipeline that lets your team focus purely on high-fit conversations.

This is just an overview, an aggregated description of our entire workflow. There’s more to the actual work, process, tools, sales thoughts, and marketing logics involved. Read it in the post below:

What sets us apart

1. We’re more than a Clay agency. We are a sales automation agency with sales acumen before Clay. So, every automation, filter, API, or webhook is tied to a conversion goal.
2. Instead of sticking to one tool, we build layered systems with PandaMatch, LeadMagic, Hunter, BounceBan, Apify, n8n, Periodix, Instantly, and more.
3. Most providers stop at email sequences. We build entire pipelines and engineer GTM systems that watch for buyer intent, personalize outreach, automate follow-ups, and qualify inbound leads.
4. Our clients don’t just “run campaigns”—they get a 24/7 sales infrastructure that adapts and scales.
5. With us, you get clear and immediate business outcomes with shorter sales cycles, higher conversion rates, better-qualified pipeline, and lower customer acquisition costs.

Note: Struggling to connect with decision-makers in your target market? We’ll run a completely done-for-you outbound campaign and automate your sales prospecting process to generate a pipeline with prospects ready to engage on autopilot.
