TL;DR: Your CRM’s closed-won folder isn’t an archive; it’s your most accurate ICP. By integrating Lusha natively into Clay, you can turn a small list of successful customers into hundreds of enriched, signal-scored prospects that look exactly like your best buyers. Stop guessing who to call and start using a data-driven lookalike engine.


Every sales leader wants more perfect-fit leads, yet most teams build their prospecting lists based on gut feel or broad filters.

The result? Mediocre conversion rates and wasted outreach. The solution isn’t more data—it’s better signals. 

By building an ICP blueprint from your actual sales history, you can move away from manual searching and toward a high-velocity lookalike engine.

From archive to engine: The 5-step workflow

We recently sat down with Clay to demonstrate how to stop treating your CRM like a graveyard and start using it as a launchpad. 

Here is the framework for building a lookalike engine that scales.

1. Define your ICP 

Most ICPs live in a slide deck built on assumptions. 

Your closed-won data is different—it’s empirical. It tells you exactly which industries, sizes, and growth trajectories actually convert.

  • The action: Export the accounts you’d clone if you could. Feed that list into Clay.

2. Build the blueprint with Lusha 

Once your wins are in Clay, run Lusha enrichment. You aren’t just doing data entry; you are building a precise profile of your buyer.

  • The data: Pull company size, industry, location, and verified headcount.
  • The goal: Create a blueprint that tells the system exactly what to look for next.

3. Generate a lookalike list 

Using Lusha’s recommendation engine inside Clay, you can transform a small sample into a massive opportunity. In our recent demo, 50 accounts became 600+ enriched lookalikes. These are accounts your reps have likely never touched, but they match your successful history almost perfectly.

4. Score by signal, not instinct 

A list is only useful if you know who to call first. We use Lusha’s signal layer to find companies “in motion”:

  • Headcount growth: Are they hiring?
  • Web traffic: Is their digital footprint expanding?
  • Executive hires/funding: Are there “change events” that indicate a budget is available? The companies matching your blueprint and showing activity become your priority tier.

5. Push back to CRM 

The final step is removing the “admin tax” from your reps. The top-tier prospects are pushed back into Salesforce—enriched and prioritized. Your team spends Monday morning selling, not researching.

Quality data: The foundation of the stack 

For GTM teams, the quality of the data determines the outcome. A lookalike engine built on stale data produces mediocre results quietly, wasting months of sales effort before anyone notices the lack of conversion.

“If I started with maybe 50 or 100 companies, Lusha has expanded that list into almost 600 companies, many of which I likely don’t have in my CRM.”Everett Berry, Head of GTM Engineering at Clay

When your ICP blueprint is built on Lusha’s verified, continuously updated data, the output reflects reality. 

That’s the difference between a simple list and a revenue-generating system.
