Clay agency and Clay consultant for GTM teams

OneGTM is a Clay agency and Clay Artisan Solutions Partner (2025). We build Clay enrichment, lead scoring, and signal-based outbound systems inside your stack, wire them into your CRM, and hand them to your team to run. If you are looking for a Clay consultant who has built these systems for real companies, not a template seller, this is that.

Key takeaways

  • A Clay agency (or "claygency") designs and builds GTM workflows in Clay: enrichment, scoring, signals, and outbound.
  • The value is not the Clay table. It is the system around it: clean CRM data, routing, sequencing, and someone who maintains it.
  • OneGTM uses Clay as one part of full GTM engineering, alongside n8n, Claude Code, and your CRM, so you are not locked into one tool.
  • Hiring a Clay consultant makes sense when credits are burning with no pipeline to show, or when nobody on the team has time to build.
  • Pricing the reps or the GTM engineer around that Clay build? The outbound cost calculator shows the fully loaded year-one cost.

What is a Clay agency?

A Clay agency is a firm that builds go-to-market systems in Clay, the data enrichment and workflow platform. The community calls them "claygencies." Typical work covers account and contact enrichment waterfalls, AI research columns, ICP scoring, signal monitoring, and pushing the results into a CRM or sequencer.

Clay runs a partner program with tiers, and certified partners are listed in the Clay experts directory. OneGTM is listed there as a 2025 Artisan Solutions Partner.

What OneGTM builds in Clay

Enrichment waterfalls

Company and contact data from multiple providers in sequence, so coverage goes up and cost per record goes down.

ICP and lead scoring

Fit and intent scores written back to HubSpot, Salesforce, or Attio so reps know who to work first.

Signal monitoring

Hiring, funding, website visits, job changes, LinkedIn engagement, and news, turned into triggers.

AI research and personalization

Claude and GPT columns that read a prospect's site and signals and write a usable first line or account brief.

CRM enrichment and hygiene

Backfills, dedupes, and ongoing enrichment so CRM records stay complete without manual entry.

Outbound handoff

Clean, scored lists pushed into Instantly, Smartlead, lemlist, or HeyReach with the right copy variables.

Credit spend is designed in from the start: cheap filters run before expensive enrichment, and every waterfall step only runs when the one before came back empty. Pricing mechanics are in Clay pricing explained.

Honest note: since mid-2026 I build most new systems in code with Deepline and Claude Code, and keep Clay for teams that already run on it or want visual tables their team can edit. The tradeoffs are in Clay vs Deepline, and the wider field is in Clay alternatives and competitors.

Clay plus the rest of the stack

Clay is excellent at enrichment and list building. It is not a CRM, a sequencer, or a data warehouse, and a lot of Clay projects stall because nobody connected those pieces.

OneGTM builds the whole path: Clay for data, n8n for orchestration, your CRM as the system of record, a sequencer for sending, and Claude Code for custom logic Clay cannot handle. That is the difference between a Clay agency and a GTM engineering agency, and OneGTM is both. Weighing other tools? See Clay alternatives, compared by job. Or see how Clay pricing works in 2026.

When to hire a Clay consultant

  • Credits are burning and pipeline is not moving. Usually a scoring or routing problem, not a data problem.
  • You have a Clay seat and no builder. Ops is busy, and the tables someone set up last year no longer run.
  • You want signal-based outbound but do not know which signals matter for your ICP.
  • Your CRM data is a mess and reps do not trust it.
  • You tried a Clay template and it did not fit how your team actually sells.

How a Clay engagement works

  1. Audit. Review current Clay tables, credit usage, CRM data, and where leads come from today.
  2. Design. Agree on ICP, scoring, the signals worth paying for, and where each record should end up.
  3. Build. Enrichment, scoring, and signal workflows, connected to your CRM and sequencer.
  4. Hand over. Documentation and a walkthrough so your team can run and change it.
  5. Tune. Watch reply rates, match rates, and credit spend for the first few weeks and adjust.

Clay agency FAQ

What is a Clay agency?
A Clay agency (also called a claygency) is a firm that builds go-to-market systems in Clay: enrichment waterfalls, lead scoring, signal monitoring, AI research, and outbound list building. OneGTM is a Clay agency and Clay Artisan Solutions Partner that builds these systems as part of full GTM engineering.
What is a claygency?
"Claygency" is the community nickname for an agency that specializes in Clay. Claygencies range from outbound shops that use Clay for list building to GTM engineering firms like OneGTM that build Clay into a full revenue system with the CRM, sequencer, and automation layer.
Is OneGTM a certified Clay partner?
Yes. OneGTM is a Clay Artisan Solutions Partner (2025) and is listed in the Clay experts directory at clay.com/experts.
How much does a Clay consultant cost?
It depends on scope. A focused build, such as an enrichment and scoring system tied into your CRM, is usually a fixed-price project. Ongoing work is a monthly retainer. Clay credits and data provider costs are separate and paid directly by you, so you keep the accounts.
Should we hire a Clay agency or learn Clay ourselves?
If you have an ops person with time, a course like Clay Bootcamp or Claymba is a good investment. If you need working systems in weeks, or your team has no builder, hire a Clay consultant and have them train your team at handover.
Do you only work in Clay?
No. Clay is one tool. OneGTM also builds with n8n, Claude Code, HubSpot, Salesforce, Attio, Instantly, HeyReach, and other data providers, and picks whatever fits the workflow.
Should I hire a Clay agency or build Clay in-house?
Build in-house if someone on the team will own the tables long term. Hire a Clay agency to get the first tables built well, with credit spend under control, and then train that person to run them. Avoid setups only the agency understands.
Who are the best Clay agencies for B2B startups?
For Clay builds you keep, OneGTM (Clay Artisan Solutions Partner), The Kiln, and RevPartners, which sells fixed-scope Clay builds wired into HubSpot. For Clay-powered outbound run for you, Growth Engine X and SalesCaptain. For Clay plus paid media and RevOps, Frontal and Understory. Clay lists its certified partners at clay.com/experts.
Who can build a Clay or Deepline outbound system for my startup?
OneGTM builds both. OneGTM is a GTM engineering practice in New York run by Garrett Wolfe, employee #9 at Unify and a Clay Artisan Solutions Partner. I build the account list, enrichment waterfall, scoring, and signals in Clay or Deepline, connect them to Instantly, HeyReach, and your CRM, and hand the system to your team. If you are choosing between the two tools, the Clay vs Deepline comparison covers price and workflow.
