Why we built this practice

Most teams buy Clay
and never ship.

Clay is powerful, but the learning curve is real. Most teams sign up, build a few tables, burn through credits on enrichment that does not match their ICP, and abandon it within a quarter. A specialist Clay agency removes that risk. closed:in runs Clay daily for our own outbound and for every client engagement, so the workflows we ship for you are battle-tested in production.

Official Solutions Partner

Listed on Clay's official partner directory. Vetted and certified to build production Clay workflows for clients.

We use Clay daily

Clay is our primary enrichment layer for every client. We know which providers return data versus burn credits, and which Claygent prompts actually work in production.

End-to-end deployment

Not just setup. We build the tables, write the Claygent prompts, wire Clay into your CRM, and document everything so your team can take over.

What we ship

Clay workflows that
run in production.

Waterfall enrichment

Email and phone waterfalls across Apollo, Findymail, Datagma, Hunter and other providers, sequenced for hit rate and cost. We tune for your specific ICP.

Custom Claygent prompts

Frequently asked

Questions, answered.

What does a Clay agency do?

A Clay agency designs and builds Clay workflows for B2B teams that need enriched, accurate prospect data but do not want to learn the platform themselves. closed:in handles waterfall enrichment setup, Claygent prompt engineering, signal-based scoring, CRM synchronization, and ongoing maintenance of Clay tables.

What is a Clay Solutions Partner?

A Clay Solutions Partner is an agency officially vetted and certified by Clay to build Clay-based workflows for clients. closed:in is on Clay's official partner directory at clay.com/experts/partner/closedin.

How is closed:in different from other Clay agencies?

We do not just set up Clay and hand it over. We run Clay daily for our own outbound and for client engagements. That means our workflows are battle-tested, our Claygent prompts are tuned for real production use, and we know which enrichment providers actually return data versus burning credits.

Do I need my own Clay subscription?

Yes. Clay workflows live in your Clay workspace so you own the data and templates after the engagement. We help you pick the right Clay plan based on monthly enrichment volume.

How much does a Clay engagement cost?

Clay-only engagements typically run between EUR 2K and EUR 6K for initial setup, plus an optional monthly retainer for ongoing optimization. Full outbound engagements that include Clay, copy and infrastructure are EUR 3K to EUR 8K per month.

Which CRMs do you integrate Clay with?

Most commonly Close, HubSpot, Salesforce and Pipedrive. Clay also pushes into Google Sheets, Airtable and Slack, and we wire those up where they fit the workflow.

How long does a Clay project take?

A standard Clay engagement runs 2 to 3 weeks from kickoff to production. Custom Claygent workflows with multi-source enrichment, signal scoring and CRM sync can take 3 to 6 weeks depending on complexity.
