Build and launch audiences in minutes
Iterate without paying to pre-enrich every audience
Turn campaign performance into the next action
Pricing model
Clay
Credits are consumed to source, enrich, and process records before the audience’s performance is known
Primer
Pricing is based primarily on audiences and, to an extent, activated ad spend—not enrichment credits for every record tested
Why it matters
Paid media requires constant experimentation at scale. Teams should be able to test audiences without paying to enrich every idea first
Primary use case
Clay
General-purpose GTM data enrichment and workflow orchestration
Primer
B2B audience intelligence, activation, measurement, and optimization for paid media
Why it matters
Primer’s paid-media specialization is designed to produce better campaign ROI
Time to production
Clay
Teams must configure sourcing, enrichments, logic, and destination syncing
Primer
Easy, intuitive audience builder with paid-media workflows already built in
Why it matters
Launch campaigns within minutes of signing up
Audience creation
Clay
Assemble audiences through connected sources, searches, enrichment steps, and custom workflows

Why it matters
Primer removes complexity between an audience idea and activation
Audience iteration
Clay
New audience tests may require additional enrichment and workflow credits
Primer
Quickly build, evaluate, archive, replace, and relaunch audiences
Why it matters
Test more ideas and learn faster without watching a credit balance
Scale
Clay
Credit consumption increases as more records are sourced, enriched, refreshed, and tested
Primer
Designed for large, continuously changing paid-media audiences
Why it matters
Advertising performance depends on reaching and continually optimizing audiences at scale
Paid-media specialization
Clay
Paid media is one component of a broader GTM platform
Primer
Purpose-built for B2B advertising workflows and campaign outcomes
Why it matters
Product decisions and recommendations stay focused on improving media performance
Cross-channel activation
Clay
Destination activation requires configured workflows, with native support still expanding
Primer
Activate and manage audiences across major advertising destinations from one platform
Why it matters
Reach the same buying audience wherever campaigns run
Audience exclusions
Clay
Exclusions can be built through custom data and workflow logic, with enrichment credits required where records must be enriched
Primer
Create anti-ICP and suppression audiences of up to 50 million records without paying to enrich every record
Why it matters
Stop wasting budget on employees, customers, competitors, and poor-fit accounts
Measurement
Clay
Reporting is not designed around optimizing paid-media audience performance
Primer
Audience-level performance and incrementality measurement
Why it matters
Understand whether an audience changed outcomes—not only whether records were activated
Recommendations
Clay
Agents can help score accounts, build audiences, and recommend GTM plays, but are not focused on in-campaign audience performance
Primer
Identify what performed, why it performed, and which audience or adjustment to try next
Why it matters
Primer’s recommendations help improve the next media investment
Performance-to-action
Clay
Teams must construct and maintain the feedback workflow themselves
Primer
Move from campaign insight to a newly assembled and activated audience in minutes
Why it matters
Shorten the loop between learning and the next campaign
Operating Model
Primer gives you the paid-media
operating model out of the box
With Clay, teams typically configure:
Data sourcing
Record enrichment
Audience logic
Refresh schedules
Destination syncing
Primer is built around a different workflow:
Build
an audience
an audience
Preview, refine it
and activate
and activate
Measure

Use those insights
to build the next audience

Paid media isn’t a one-time enrichment project. Strong audience strategies emerge through repeated experimentation.
Primer lets marketers move from idea to campaign without first designing, debugging, and maintaining a custom data workflow
Audience experimentation
Where Primer wins for paid-media
experimentation
Audience experimentation
With a credit-based model, every new audience idea can require more:
Record sourcing
Enrichment
Data refreshes
Workflow steps
And those costs happen before you know whether the audience will perform.
With Primer you can:
Test different audience definitions
Add or remove buying roles
Broaden or narrow targeting
Build anti-ICP and suppression audiences
Replace underperforming audiences
Scale successful segments
And those costs happen before you know whether the audience will perform.
That means:
Test more audience ideas
Learn what works faster
Experiment without watching a credit balance
Invest based on performance instead of enrichment cost
You aren’t rewarded for enriching the most records.
You’re rewarded for finding the audience that produces the best return.
Measurement
Building an audience isn’t enough
Understand what actually performed
Clay can help teams find accounts, enrich records, score opportunities, and orchestrate GTM workflows.
Primer goes deeper into what happens after an audience enters a campaign.
Primer helps paid-media teams understand:
- Which audiences produced meaningful lift
- Which companies and roles correlate with performance
- Where budget is being wasted
- Which exclusions could improve efficiency
- Which audience should be tested next
Primer turns performance into action
The workflow doesn’t stop at reporting.
Understand what performed → identify why → recommend the next audience or adjustment → build it → activate it.
- When a segment produces lift, expand it.
- When a company attribute, role, or exclusion correlates with better outcomes, incorporate that learning into the next campaign.
- When an audience underperforms, refine it.
The goal isn’t simply to build an audience. It’s to continuously improve the return generated by that audience.

- You need audience-level performance or incrementality measurement
