You close a deal. Yalc finds the companies that look just like it, verifies the CEO and the head of sales or marketing, writes the outbound, and parks a paused campaign in Lemlist plus the contacts in your HubSpot. You just hit send.

Before and after

What changed

Before

You close a deal and never build the pipeline that compounds on it. In the standup someone asks "who else looks like the one we just won." Two days later an SDR hand scrapes a list off Sales Nav, half the companies are wrong, nobody is enriched, there is no campaign, and the momentum is gone.

After

You close a fintech deal and tell the watcher you closed new deals. It comes back with a plan and waits. You reply go. Minutes later three lookalike companies are in your HubSpot with the CEO and the head of sales verified, mobile and email, and a paused Lemlist campaign is built with the copy already written. You read it and hit send.

How it works

The breakdown, gate by gate

1

Read your recent closed won

A HubSpot search pulls your closed won deals and follows each one to its company, so the agent knows the industry, headcount, and deal size behind every win.

2

Synthesize the ICP pattern

The agent clusters the wins by industry, headcount band, and average deal value, and writes the pattern to your Yalc intelligence store as a hypothesis that sharpens every time it recurs.

3

Find the lookalikes

Yalc lookalike search returns the companies in the public market that most resemble each win, then merges and ranks them into one deduped pool.

4

Dedupe against your pipeline

Anything already in your HubSpot pipeline is dropped before a single credit is spent, so you never enrich or pitch an account a rep is already working.

5

Verify the decision makers

For the top accounts the agent finds the CEO and the head of sales or marketing and FullEnrich returns their verified work email and mobile. Anything unverified is left blank, never guessed.

6

Build the campaign, paused

The agent writes the outbound sequence, creates a Lemlist campaign with the leads loaded but paused, and syncs the contacts into HubSpot. Nothing sends until you assign a sender and hit start yourself.

Results

What goes in, what comes out

Three net new lookalike accounts, the decision makers verified, an outbound campaign written and paused, all from one closed won pattern. Zero manual prospecting between the win and the send.

You closed one. Yalc finds the next three, verifies the people, and builds the campaign.

It plans first, waits for your go, and never sends a thing until you do.

From a closed won deal to a verified lookalike campaign, paused and ready to send.
