20 Best Clay Experts for Outbound Sales Automation, GTM Engineering, and ABM In 2026
In this post:
Most teams searching for a Clay expert end up on the same page, the official Clay Experts directory.
The directory lists the certified partners alphabetically, sorts them by region, and offers a single line on what each one does.
For a category that has split into three different jobs to be done since 2024, that is not enough information to hire on.
A team looking for outbound execution lands on the same list as a team looking for a fractional GTM engineer or an ABM consultant.
The page does not tell you who builds what, who is best for what scale, or what each operator's actual position is on the work.
So you guess, you reach out, you take half-hour calls with five different people, and you still cannot tell which one to hire.
This list exists to fix that. We have worked alongside, learned from, or competed with most of the people on it, and the goal here is to give you a fair read on what you can get from the best of us.
We’ve cherry-picked 18 of the most effective Clay-powered sales automation and GTM 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
One quick note before we start. This is not a competitive ranking, and it is not a list of agencies that lose to Nebor on every engagement.
We put ourselves at the top by convention, the same convention every other agency on a roundup like this uses for its own.
Let’s get started.
18 Best Clay experts for Clay-powered outbound sales automation and GTM engineering
1. Andrew van Rossenberg and Yannick Kok (Nebor)
LinkedIn: Andrew van Rossenberg
Yes, that’s us and we are top of the list.
Beyond convention, we’d argue we earn the spot for a reason the other experts don’t share.
We’re Andrew and Yannick, founders of Nebor. Andrew spent 10+ years building B2B sales motions for start-ups and scale-ups before he ever sold the work to a client.
Yannick spent 10+ years in corporate SaaS sales, including a stint at OneStream where he took the worst-performing global BDR team of eight and turned it into the best-performing one within 18 months.
Combined, that is 20+ years of running outbound and full-cycle B2B sales before either of us ever sold the work as a service.
Salespeople first, automation experts second.
That sequencing is the line we put down on day one of every engagement. Most Clay shops are tool experts who learned sales second.
We are the opposite of that.
Every workflow we ship traces back to a sales call we ran ourselves first, which is why our systems read more like sales playbooks with automation on top than like enrichment chains chasing an outbound use case.
Our Clay and sales automation expertise + how our GTM motion works
With us, you get a connected revenue system instead of a campaign with Clay tables. Five stages, all running on the same Clay tables, all sitting in your accounts at the end of the build, all working as one motion instead of four disconnected ones.
Stage 1: strategy before the stack
Stage 1 covers the GTM motion, the signals, the buyer journey, and the ICP modeling. Three to four weeks of pre-Clay work that decides whether everything downstream amplifies signal or amplifies error.
You get:
Smart ICP frameworks based on your own customer data
Data ingestion from CRM, website, and LinkedIn into Clay to 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 Discolike and Ocean.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.
Most agencies skip past this and pay for it in stage four. We start there because every workflow we will build later depends on whether the diagnosis is right.
Stage 2: orchestrating multichannel outbound outreach for LinkedIn, cold email, and cold calling
This stage supposes that we’ve worked through the first one and have all the data ready and well sorted in your Clay tables. So, from there, we connect the right outreach tools and run cold outbound campaigns from there.
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 or Lemlist for cold email outreach
LinkedIn automation via HeyReach.io or Lemlist
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 we’ve gathered in Clay so they can pick up the phone and close deals from conversations we started.
Stage 3: inbound, intent, and visitor de-anonymization on the same tables
Your meeting booking platform,Leadinfo,RB2B, andApify all sit alongside Clay in this stage.
Any type of inbound or demand gen activities that happen on your website like form fills, hand-raises, booked meetings or demos, visiting key pages on your website, etc fires a webhook where we catch the lead and their data.
We feed that data back to the same Clay table to run the enrichment and outreach automatically. This also helps your team with inbound lead capture and qualification. The Clay workflow scores the lead against your ICP and sends them a message automatically.
That’s a job your team doesn’t have to worry about anymore because the workflow we build takes care of it. We have a more elaborated blog on website visitor tracking workflows you can read for more information on this.
Stage 4: you get intent data buying signals
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 readers, n8n.io, 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.
Stage 5: the RevOps backbone that holds the system together
We work inHubSpot orSalesforce, depending on what you already run.
The RevOps backbone covers dedupe and CRM hygiene, lifecycle automation, attribution that survives a nine-month cycle, and an ICP feedback loop that pushes closed-won and closed-lost data back into the prospecting tables.
This is the part of the system that survives the engagement. It is also the dividing line between a Clay expert who runs your campaigns and one who builds your revenue motion.
We’ve covered the broader category in our post on the RevOps agencies in Europe, and the position behind the work is in why we are not a lead generation agency.
What separates us from the other Clay experts on this list
What separates us comes down to three patterns the rest of the category does not run consistently.
We map your entire GTM motion before any workflow goes in, which is why our pre-Clay phase usually runs three to four weeks while most agencies move into the tool by week one.
The composable stack we ship evolves with the market rather than against it, so when a new signal source becomes useful eighteen months from now, the workflow extends instead of needing a rebuild.
And adding new segments, new markets, or new signals does not require tearing the existing tables down and starting from scratch.
You can run the system yourself once we wrap, hand it to a junior operator inside the team, or pause us and turn the engagement back on six months later.
If you want to talk through what the system would look like for your motion specifically, you can find us on LinkedIn or book a meeting with us.
2. Michel Lieben, founder and CEO of ColdIQ
Michel Lieben is one of the most visible voices in the AI-driven sales prospecting category, with a steady stream of LinkedIn posts, webinar appearances, and tactical breakdowns that make him one of the most popular automation operators and Clay experts.
His company, ColdIQ, runs the full outbound stack as a service, including email infrastructure setup, audience research, data enrichment, campaign optimization, and personalized outreach.
Michel also offers a course that teaches in-house GTM teams how to build sales systems around Clay and the surrounding stack.
The educational layer is part of why ColdIQ is one of the most-referenced names in the category, even for teams who never end up hiring them directly.
You can read our post on the best ColdIQ alternatives to further understand their services and see how they compare against most of the agencies in the field.
Clay and GTM engineering/sales automation expertise
Integration of multiple data providers: Michel connects Clay directly with data providers via APIs, which makes the enrichment chain cheaper to run than relying on any single source.
AI-powered personalization at scale: Uses Clay's AI tools, including the AI formula generator and research agent, to automate the personalized parts of outreach without losing accuracy.
Educational content creation: Michel publishes detailed comparisons of data enrichment services and guides on using AI for sales prospecting on his site and LinkedIn page.
Coaching and training programs: ColdIQ runs coaching programs that train internal teams to build and run AI-driven outbound systems on Clay.
3. Patrick Spychalski, co-founder of The Kiln
Patrick Spychalski is one of the most technically deep operators in the Clay community, and the founder of The Kiln gets called in for the workflows other shops would farm out to engineering.
Patrick was part of the early Clay building team before he co-founded The Kiln, which is the credential that matters most in this category.
The Kiln itself is a Clay-specialist consultancy serving B2B GTM teams that want CRM data cleaning, complex lead scoring, and hyper-personalized outbound campaigns built and handed back.
Patrick’s audience tilts toward technical operators and senior RevOps leaders rather than companies looking for a managed campaign service, which is why his work and ours rarely compete for the same engagement.
If you want to compare The Kiln next to the other players in the industry, we have a post that covers their positioning and best alternatives.
Clay and GTM engineering/sales automation expertise
Sales workflow automation. Designs and ships automated sales workflows that handle the lead generation and follow-up logic most teams would otherwise build with engineering help.
Deep data aggregation work. Patrick's grasp of the Clay platform sits on the technical edge, including custom data integrations and workflows that produce higher accuracy than the standard provider waterfall.
Creative data sourcing. Webinars and tutorials on data sourcing techniques pull from sources most agencies do not consider when building enrichment chains.
Hyper-personalized outreach. Combines Clay's enrichment with AI tools to write messages tied directly to the data points already pulled into the table.
4. Balša Kosić, COO and Partner at OneAway and founder at Prospeqt
Balša Kosić was the COO and a partner at OneAway, a Clay Enterprise Partner that has built over 190 Clay tables across more than 50 B2B engagements as of 2026.
Their work spans across outbound automation, GTM engineering, and CRM hygiene, with the engagement shape flexing between full campaign delivery and design-only handoff depending on what each client brings to the table.
Balša’s lane at the agency is the Clay-engineering and template work that OneAway productizes across clients.
The 190-table number matters because it implies the kind of workflow library Clay experts eventually build, where new client engagements draw from previously battle-tested templates rather than starting from scratch every time.
He’s now moved to building and running his own agency, Prospeqt.
Clay and GTM engineering/sales automation expertise
Clay template development: Balša creates Clay templates that scale across multiple clients, with workflows tuned to keep email bounce rates low and personalization variations high.
Data enrichment chains: Integrates Clay with multiple data providers to assemble accurate prospect records that sit at the center of the agency's outbound work.
CRM hygiene: Cleans and updates client CRM records as part of the engagement, which keeps outbound campaigns running off clean data rather than stale fields.
Custom workflow automation: Has overseen the development of over 500 custom Clay tables, automating the sales tasks that would otherwise sit on a rep's plate.
Educational content creation: Publishes tutorials on Clay implementation and the workflows OneAway uses internally.
5. Naufal Nugroho, head of GTM engineering at Understory
Naufal Nugroho leads GTM engineering at Understory and is a certified Clay expert.
His path into the work runs through the AE seat first, then through building his own cold email and Clay agency to six figures, then through merging that operation into Understory where he now runs outbound and account-based programs.
Naufal’s work includes Clay, AI, and signal monitoring, where the focus is on identifying buying intent and acting on it before competitors do.
His case studies showcase more of the technical end of the GTM-engineering category, including a system that processes 1,000 annual reports in under two hours and pushes the resulting intent briefs into rep-facing tools.
If you want a Clay expert who can architect full-stack GTM systems on Clay beyond running a single campaign, Naufal is one of the strongest picks in this group.
His work is heavier on signal-driven workflow logic than on managed-campaign throughput, which is the right shape for in-house teams that already have rep capacity but need the upstream system rebuilt.
Clay and GTM engineering/sales automation expertise
AI-driven prospecting: Uses LLMs including GPT, Gemini, and Grok to build prospect lists based on intent data like recent funding rounds and leadership changes, which standard providers often miss.
Signal monitoring systems. Builds workflows in Clay that score signals like funding rounds or product launches and push the alerts into Slack for the relevant rep to act on.
10-K report analysis at scale: Built a system that pulls and processes 1,000 annual reports in under two hours, scoring intent signals and generating rep-facing briefs via Clay and Make.com.
Team-driven engagement workflows: Automates the collection and qualification of leads generated from internal team posts via a Teamfluence-to-Clay-to-outreach pipeline.
Central-hub Clay stacks: Uses Clay as the central hub in GTM stacks, integrating with OpenAI, Instantly, LeadMagic, Findymail, and other tools to run personalized outreach at scale.
6. Adam Rahmouni and Jovan Shojlevski, leadership at Grow Surely
Adam Rahmouni and Jovan Shojlevski run Grow Surely, a Clay-certified outbound automation agency that now reports over $7.5M in client revenue generated through the systems they ship across more than 100 engagements.
The split in their partnership is unusually clean for the category. Adam runs the personalization and outreach systems work, and Jovan runs the deliverability layer underneath it, which is the part of cold email that decides whether the rest of the work even reaches an inbox.
Their combined expertise means a Grow Surely engagement covers both halves of the outbound problem at once, from the Clay enrichment chain through the email infrastructure that delivers the message.
If you want to compare Grow Surely against the wider category, we worked on a blog about Grow Surely alternatives where you can see how they compare against the other agencies.
Clay and GTM engineering/sales automation expertise
AI-powered data enrichment. Uses Clay alongside OpenAI APIs to enrich lead data and run personalized outreach at scale, with the AI parts tied directly to the data points already in the table.
Hyper-segmentation. Uses AI to verify each contact individually, which produces more precise targeting than standard prospecting-platform filters.
Email infrastructure work. Implements a diversified email infrastructure across Google, Outlook, and Maildoso to keep deliverability rates high under load.
Campaign management through Instantly. Runs all email campaigns through Instantly, which handles inbox warming and the centralized dashboard for campaign oversight.
Deliverability expertise. Jovan brings experience managing over 14 million emails, with a focus on sender reputation, DNS configuration, and spam placement fixes.
7. Josh Whitfield, founder of Content Marketing Media
Josh Whitfield runs Content Marketing Media (CMM), an outbound agency that bills itself as the only one globally certified across Clay, Instantly, HeyReach, and Octave at once.
With 17+ years in business leadership before he founded CMM, Josh’s positioning sits closer to the senior-operator end of the agency category than the founder-led-velocity end.
The four-platform certification matters because it covers the cornerstone tools of modern outbound rather than just the data layer.
CMM’s engagement shape covers lead generation, messaging, and email deliverability as one connected scope rather than three separate workstreams, with personalized video as a layer on top that other agencies usually treat as optional.
Clay and GTM engineering/sales automation expertise
AI-driven data enrichment: Uses Clay's integrations to turn static lead lists into data-rich prospect profiles, pulling from LinkedIn, Google Maps, and company tech stacks.
Personalized video outreach: Josh combines Clay with SendSpark to ship dynamically personalized videos that lift cold email engagement rates beyond what plain text can produce.
Automation of outbound pipelines: Automates the full outbound process, from prospect extraction to customized response triggers, which keeps the team off the manual parts.
Deliverability optimization: Offers email infrastructure evaluations including domain and IP testing, so inbox placement stays consistent under volume.
Integration with CRM systems: Wires outreach processes into Salesforce or HubSpot, enriching existing data and keeping the pipeline reporting layer accurate.
Educational content creation: Josh publishes tutorials and webinars on outbound strategies, including the Clay workflows and cold email patterns CMM uses internally.
8. Martin Thomas, fractional growth and GTM partner
Martin Thomas works as a fractional growth and GTM partner for SaaS and B2B tech companies, with over 2,000 outbound campaigns shipped across his consulting career.
He is a Clay-certified expert and runs the work as an independent operator rather than as the founder of a named agency, which is a meaningfully different shape than most of the others on this list.
The 2,000-campaign number is the credential that matters here. The pattern recognition that comes from running campaigns across that many companies is hard to compress into a course or a playbook, and Martin’s engagements offer that experience to teams who are still figuring out which outbound shape will work for them.
Clay and GTM engineering/sales automation expertise
End-to-end acquisition design: Designs and automates the full acquisition system across platforms and tools rather than working on a single channel.
Outbound campaign management at scale: Has run over 2,000 outbound campaigns using AI and data-driven approaches to keep reply rates high under volume.
CRM cleanup: Cleans CRM processes so the data flow stays accurate and the lead routing actually matches the sales motion.
Data enrichment: Uses Clay to enrich lead data for personalized outreach, with the enrichment chain tuned per client rather than templated.
Process iteration: Continuously refines the sales processes inside each engagement, including the parts that need to flex as the client's GTM motion evolves.
9. Noel Maniraguha, founder of Afonto
Noel Maniraguha runs Afonto, a B2B sales development agency built around AI-driven lead generation and outreach.
Afonto’s setup ships over 1,000 personalized emails per day across the client base and is operationally lean enough that Noel manages 15+ clients on his own with automation handling the heavy lifting.
Noel does not yet hold a formal Clay certification, but his engineering output and tactical grasp of the tool put him ahead of many operators who do. The more interesting credential is the operational one.
Running 15+ active clients with one operator means the systems Noel builds need to hold up under client load and run themselves without daily attention, which forces an operational discipline most agency-led approaches do not require.
Clay and GTM engineering/sales automation expertise
Automation depth: Has invested over 1,000 hours in building automations, with more than 90% of his work processes running on automation rather than manual execution.
Campaign cadence at scale: Built a system that ships one new campaign per client per week, which produces 10+ campaigns per month and 30+ over a six-month engagement.
Tool integration breadth: Runs a multi-tool outbound stack including HubSpot, Sales Navigator, Apollo, Vayne, ScrapeLi, Clay, Claude, GPT, Icypeas, Prospeo, and Smartlead, with the connections wired so each tool covers a clear role rather than overlapping.
10. Eric Nowoslawski, founder of Growth Engine X
Eric Nowoslawski runs Growth Engine X and is one of the most-cited names in the Clay outbound category.
He spent time as a member of the Clay team before founding the agency, and the position he has earned over the last few years is the “godfather of Clay outbound”.
Most of the workflows other Clay experts and agencies repackage publicly six to twelve months later started as Eric’s posts on the open web.
His client roster includes Forbes, Y Combinator, Refine Labs, Instantly, and ChurnZero, which gives his agency a brand-level credibility most outbound agencies cannot match.
We also worked on a blog that further explains Growth Engine X’s positioning and compares them against the other agencies in the field.
Clay and GTM engineering/sales automation expertise
Trigger waterfall campaigns: Develops custom Trigger Waterfall workflows in Clay that launch multiple campaigns based on specific triggers, including recent company founding events or new role announcements.
AI-driven personalization: Uses AI to generate personalized email content tied to the data points already enriched in Clay, so the message lands in the recipient's actual context.
Email infrastructure depth: Implements domain diversification, inbox warm-up, and the deliverability stack underneath, which keeps cold campaigns out of spam filters at high volume.
Data enrichment: Uses Clay's integrations across multiple data providers to enrich the lead data behind every campaign, rather than relying on a single provider waterfall.
11. David Emanuel Moreira, co-founder of Automate RevOps
LinkedIn: David Emanuel Moreira
David Emanuel Moreira is one of the most-referenced names in the RevOps-meets-Clay category and the co-founder of Automate RevOps, a Clay Advanced Artisan Partner.
His engagements mostly happen across the USA and the Middle East, with the work focused on building Clay workflows that handle lead generation, enrichment, and outreach inside the broader RevOps stack rather than as standalone automation.
Beyond the agency work, David runs the educator side as well. He co-leads a 6-week Clay Coaching Program that takes sales operators through the workflow design and tooling skills needed to run AI-powered RevOps inside their own teams.
Clay and GTM engineering/sales automation expertise
Clay Advanced Artisan Partner: Recognized as one of Clay's higher-tier partners, with the kind of platform-level depth that comes from running both client work and education on the tool.
Automated lead generation services: Through Automate RevOps, David ships strategy work, list building, outreach setup, and training, all tied to automated lead generation built on Clay.
AI-driven personalization: Uses AI tools alongside Clay, Apollo, and ZoomInfo for lead enrichment and prioritization, with the AI parts tied to the data already in the table.
Multi-channel outreach: Executed a LinkedIn outreach campaign that hit a 32% reply rate by qualifying connections through Clay and integrating with HeyReach for the campaign launches.
12. Jordan Crawford, founder of Blueprint and Clay advisor since 2021
Jordan Crawford is the OG independent voice in the Clay community and probably the longest-tenured external Clay advisor on this list.
He has been advising Clay since 2021 and runs Blueprint, an independent agency focused on structuring data from the public web into prospect research most other agencies cannot reach.
Government records, permits, regulatory filings, hiring threads, and competitor signals all feed into the Clay tables Blueprint builds for clients, which is a meaningfully different angle than the Apollo and Sales Navigator default the rest of the category runs on.
What Jordan ships, more than anyone else on this list, is depth on the data side. He calls one of his core frames the Pain-Qualified Segment (PQS), where prospects get grouped not by who they are but by a specific data-detectable problem they are dealing with right now.
Clay and GTM engineering/sales automation expertise
Pain-Qualified Segments (PQS): Identifies prospect groups by a specific, data-detectable problem they are facing in real time, rather than by job title or company size.
Open web as the primary data source: Government records, permits, regulatory filings, hiring threads, and competitor signals feed into Clay rather than off-the-shelf databases.
AI-agent prospect research: The Agent 7 course teaches how to chain LLMs and Clay's research agents together to reach prospects whose buying signals do not show up in standard tools.
Direct relationship with Clay product: As an advisor since 2021, Jordan often works with Clay features before they are widely documented, which helps teams pushing the platform's edge.
Tiered pricing for different commitments: Blueprint's lower tiers automate sales lists from job posts, while the enterprise tier brings Jordan in directly as a GTM data consultant.
13. Michael Saruggia, founder of The Clay Operator
Michael Saruggia is probably the strongest personal brand in the GTM Engineering space right now, and the one most likely to come up in a “where do I learn Clay” conversation with a head of revenue.
He runs The Clay Operator, where he has trained over 900 students through programs like the 80/20 GTM Engineer Course and the Clay Consultant Program. He is also the author of “The GTM Engineer”, available on Amazon.
Beyond the education layer, Michael runs Fractional GTM Engineering for mid-market companies who want to bring in a senior operator without hiring full time.
The model turns GTM Engineer from a role companies hire for once and pray works into a function they can rent for the months when the system actually needs to be built, which is a rare and useful hybrid in this category.
Clay and GTM engineering/sales automation expertise
Fractional GTM Engineering: Michael embeds with mid-market companies as the senior operator, building the Clay tables and the surrounding workflows for the months the work is needed.
80/20 GTM Engineer course: Trains both consultants and in-house operators on the parts of Clay that drive the most pipeline value, deliberately skipping the long-tail features.
Clay Consultant Program: Lower-funnel path for operators who want to land a consulting client in 60 days, with playbooks and SOPs included.
Strong public output: Author of "The GTM Engineer" book, frequent podcast guest, and a regular voice in the Clay community on what GTM Engineering actually means as a role.
Mid-market and scale-up focus: Most engagements land with mid-market companies looking to operationalize GTM Engineering rather than seed-stage startups still figuring out their ICP.
14. Nathan Lippi, founder of Clay Bootcamp
Nathan Lippi is the educator who trained the educators. Clay Bootcamp is the longest-running 1-on-1 GTM Engineering program in the category, with 300+ alumni now building careers across Clay agencies and in-house GTM teams.
Clay itself has trained 40+ employees through the Bootcamp, and the founders of agencies like The Kiln (also on this list) came through the program. That meta-layer is rarely acknowledged in lists like this, which is part of why we are putting Nathan on ours.
Clay and GTM engineering/sales automation expertise
1-on-1 GTM Engineering training: Mentorship from agency CEOs whose firms cumulatively earn $10M+ ARR, rather than a video course and a Slack channel.
300+ alumni placed: Nathan's program has produced operators inside Clay itself, inside top Clay agencies, and as independent consultants. Many of the names on this list run shops staffed with Bootcamp alumni.
40+ Clay employees trained: Clay sources GTM Engineering hires from the Bootcamp directly, which is the strongest endorsement the program has.
Real-project curriculum: The 10-week structure builds client-grade Clay tables and workflows rather than running isolated feature exercises.
Career path support: Beyond the technical training, Nathan and his mentors help alumni land their first GTM Engineering roles, which is where most operators stall when they try to learn the work alone.
15. Saharsh Agrawal, co-founder and CEO of Surface Labs
Saharsh Agrawal is the only person on this list who is productizing the Clay-style lead operations layer as actual SaaS.
He is the co-founder and CEO of Surface Labs, the YC S23 startup that is now handling 50K+ leads per month across 100+ B2B marketing teams in production.
The platform replaces the typical HubSpot Forms plus Zapier plus Chili Piper stack with one product that does the lead capture, enrichment, routing, and follow-up automation in one place.
Clay and GTM engineering/sales automation expertise
Productized lead operations: Surface Labs handles inbound capture, enrichment, qualification, routing, and follow-up automation as a single AI-powered platform.
Replaces the HubSpot Forms plus Zapier plus Chili Piper stack: One product covering the work most marketing ops teams currently run as five integrations.
AI agents in production at scale: The platform handles 50K+ leads per month across 100+ B2B marketing teams as of 2026.
YC S23 backing: Funded by Y Combinator, Garry Tan, Dharmesh Shah (HubSpot co-founder), and the AngelList CEO. The credentials are useful for the reader evaluating where bets are landing.
Engineering-led GTM perspective: Saharsh's background spans Apple, Microsoft, and the Berkeley RISE Lab, which shapes how Surface Labs treats marketing ops as a software problem rather than a workflow problem.
16. Mason Cosby, founder of Scrappy ABM
Mason Cosby runs Scrappy ABM, a boutique consultancy focused on practical, budget-conscious account-based marketing for B2B teams that cannot afford the enterprise ABM stack.
Clay sits in the data and signals layer of his work, but the orientation is ABM-first rather than outbound-first, which fills a gap none of the agency-led names higher on this list cover directly.
Mason’s ABM-first work is a useful counterweight to outbound or GTM default, especially for teams that have outbound running but cannot get the ABM motion to actually convert accounts at the scale that matters.
Clay and ABM expertise
ABM-first GTM design: Mason builds account-based programs around named-account lists, then layers Clay enrichment and signal monitoring on top, rather than starting with an outbound campaign and bolting ABM on later.
Budget-conscious Clay workflows: Targets mid-market B2B teams with ABM programs costing meaningfully less than 6sense or Demandbase plus a managed-services retainer.
Long-running practitioner podcast: Scrappy ABM is one of the longest-running ABM podcasts in B2B, with 245+ episodes covering practical execution rather than vendor pitches.
SOP-led delivery: Mason builds Standard Operating Procedures into every engagement, so the ABM motion keeps running once he steps off the project.
Speaking and workshops: Active workshop and speaking practice with frameworks tested across hundreds of consulting engagements.
17. Colin Bakker, co-founder at Utmost Agency
Colin co-founded Utmost Agency with Andrew, the predecessor to Nebor, and spent the Utmost years building Clay-powered B2B sales systems with us.
His path into the work matched ours. He came in as a former salesperson who had run his own outbound campaigns by hand and freelanced his way into systems thinking before either of us ever sold the work to a client.
Colin offers ICP modeling and TAM identification in Clay, multi-channel outreach orchestrated across Instantly and LinkedIn, intent triggers running through Apify, PhantomBuster, and n8n, and inbound qualification flows.
Clay and GTM engineering/sales automation expertise
Multi-tool sales stack design: Combined Clay with Instantly, Periodix, PhantomBuster, Apify, n8n, and FullEnrich to ship full sales systems rather than standalone campaigns.
ICP precision and TAM modeling: Built central Clay workspaces as the command center for B2B sales operations, with custom enrichment layers that targeted who, why, when, and how, rather than relying on generic Apollo or ZoomInfo filters.
Multi-channel outreach orchestration: Designed campaigns that combined email and LinkedIn with channel routing based on enrichment signals, including Outlook detection that routes the prospect to LinkedIn instead of email.
Intent data workflows: Built signal-driven outbound using RSS feeds, Apify, PhantomBuster, and Clay to surface buying triggers like funding rounds, hiring activity, and real-estate transactions in real time.
Inbound qualification automation: Connected form submissions, demo requests, and key page consumption to Clay-based scoring models so only high-fit leads ever reached sales.
Work with Yannick and Andrew (Nebor.ai) to get the sales experience led Clay workflows to generate pipeline and make your team more efficient
Clay is powerful, but only if you know how or have the right expert partner to use it correctly.
The wrong setup wastes hours. The right expert can help you unlock automated systems that save you time, bring in leads, and drive real revenue.
We built this list to make your search easier. Pick one. Reach out. And start building smarter.
The 18 names above split into three jobs to be done. Map your situation onto the right one before you start reaching out, and the shortlist falls out of the framework rather than out of brand recognition.
You want to learn Clay yourself or train your team. That is the educator bucket.
Nathan Lippi for 1-on-1 GTM Engineering coaching that builds real client-grade projects.
Michael Saruggia for a structured course and a clear consultant-track path through The Clay Operator.
Jordan Crawford for the AI-agent and open-web data sourcing side specifically.
David Emanuel Moreira's coaching program for a heavier RevOps lens, when teams need to run Clay alongside the CRM and the lifecycle layer.
You want to hire an agency or independent operator for a specific build. That is the largest group on the list and the one where situational fit matters most.
If you’re looking for a partner who possesses the sales and lead generation experience combined with Clay expertise, then Nebor is worth a serious look.
