Your best buyers are not just names in closed-won deals. They are a signal.

They show which titles care, which seniority levels can act, which departments feel the pain, and which company types are most likely to understand the value. The problem is that most teams turn those patterns into broad title searches and call it targeting.

A title search finds people who look right on paper. A lookalike buyer workflow starts from people who already proved the fit.

This prompt uses Lusha in ChatGPT to analyze your best buyer contacts, find similar contacts, verify their current roles, enrich available contact data, check company and contact signals, and create an explainable recommendation score based on verified Lusha data. Instead of building a prospect list from generic titles, you start from the buyers who already moved deals forward.

How to start

1

Open Lusha in ChatGPT

Go to Lusha in ChatGPT and click “Start chat.” Every conversation started this way is automatically Lusha-enabled.

2

Or invoke Lusha in any existing conversation

Type @Lusha in the prompt bar and select Lusha from the dropdown. Unlike Claude, Lusha does not activate automatically in every ChatGPT conversation. You must invoke it every time.

3

Add your best buyers and send

Copy the prompt below, add 5–100 seed buyers, include your ICP and exclusions, and send. Lusha finds lookalike contacts, and ChatGPT recommends who to prioritize based on the returned data.

The prompt

Start from Lusha in ChatGPT or type @Lusha before sending.

3. [LinkedIn URL / email / name + company / Lusha contact ID]

Using Lusha, do the following:

1. VALIDATE THE SEED BUYERS
   Confirm that each seed buyer can be matched to a real
   Lusha contact profile.

   Return:
   - Name
   - Current title
   - Current company
   - Department
   - Seniority
   - Location
   - Match status

   If fewer than 5 seed buyers can be verified, ask me
   for more seeds before running the lookalike search.

2. FIND LOOKALIKE BUYERS
   Use the verified seed buyers to find similar contacts.

   Prioritize contacts that appear similar across:
   - Title
   - Department
   - Seniority
   - Company type
   - Industry
   - Company size
   - Region
   - ICP relevance

   Do not include contacts or companies listed in the
   exclusion section.

3. VERIFY EACH LOOKALIKE CONTACT
   For each lookalike buyer, return:
   - Name
   - Current title
   - Current company
   - Department
   - Seniority
   - Location
   - LinkedIn profile if available
   - Whether the person appears to still be at the company

4. ENRICH CONTACT DATA
   For each lookalike buyer, return:
   - Verified business email availability
   - Direct or mobile phone availability
   - DNC status if available
   - Last updated date if available

   If contact data is not available or cannot be revealed,
   say so clearly rather than guessing.

5. ENRICH EACH COMPANY
   For each lookalike buyer’s company, return:
   - Company name
   - Domain
   - Industry
   - Employee count
   - HQ location
   - Revenue range if available
   - Company LinkedIn if available

6. CHECK RECENT SIGNALS
   For each lookalike buyer or their company, check recent
   signals from the last 6 months, if available.

   Prioritize:
   - Promotion
   - Company change
   - Hiring surges
   - Hiring surges by relevant department
   - Hiring surges by location
   - Headcount increases or decreases
   - IT spend changes
   - Website traffic changes
   - Commercial activity news
   - Corporate strategy news
   - Financial events news
   - People news
   - Product activity news
   - Risk news
   - Intent topics related to my product, if available

7. CREATE AN EXPLAINABLE RECOMMENDATION SCORE
   Create a recommendation score from 1-100 using only
   the Lusha data returned and the ICP context I provided.

   Break the score into:
   - Buyer match: 35 points
     How similar the contact appears to the seed buyers.

   - ICP fit: 30 points
     How well the contact and company match my target market.

   - Timing: 20 points
     Whether recent contact or company signals make outreach
     more timely.

   - Actionability: 15 points
     Whether verified contact data is available and usable.

   Make the score explainable. Do not present it as a
   prediction that the buyer will convert or purchase.

   If there is not enough verified data to support a score,
   mark the score as low-confidence and explain what is missing.

8. ASSIGN A RECOMMENDATION
   Assign one recommendation:

   Contact now:
   Strong buyer match + high ICP fit + relevant signal
   or strong actionability.

   Add to campaign:
   Strong buyer match + good ICP fit, but weaker timing.

   Nurture:
   Partial fit, weak signal, or unclear urgency.

   Review:
   Interesting match, but missing data or unclear fit.

   Exclude:
   Poor fit, disqualified, competitor, existing customer,
   open opportunity, or unverifiable contact.

9. CREATE AI RECOMMENDATIONS
   For each Contact now buyer, write:
   - Why this person looks like our best buyers
   - Why now may be a good time to reach out, if supported
     by signals
   - What angle to lead with
   - One subject line under 7 words
   - One opening line under 30 words
   - One discovery question

   Do not:
   Invent signals, titles, responsibilities, tools, vendors,
   internal projects, contract status, or buying intent.
   Claim the buyer is ready to buy.
   Present the score as a conversion prediction.
   Include excluded contacts or companies.
   Force personalization when the data is weak.

10. OUTPUT FORMAT
   Return:
   - Seed buyer validation
   - Lookalike buyer table
   - Contact verification
   - Contact data availability
   - Company enrichment
   - Recent signals, if any
   - Explainable recommendation score with breakdown
   - Confidence level
   - Recommendation
   - Recommended outreach angle
   - Excluded contacts and why

Do not invent contacts, companies, emails, phone numbers,
signals, scores, or recommendations. If Lusha cannot verify
a contact, company, or signal, mark it clearly.

Why use Lusha in ChatGPT for AI lookalike buyer recommendations

 

Your best buyers show more than who bought. They show who understood the pain, had the authority to move, and sat close enough to the problem to care.

Lusha helps turn that pattern into a new prospect list. The prompt uses your verified seed buyers to find similar contacts, then enriches each buyer with current role, company context, and available contact data. ChatGPT adds the recommendation layer: why the buyer looks similar, whether the timing is strong, and what action to take next.

The scoring step matters because not every lookalike buyer is equally actionable. One person may look similar to your best buyers but have no available contact data. Another may be a slightly weaker match but has a recent promotion signal, strong ICP fit, and usable contact data. The prompt makes those tradeoffs clear.

The result is a prospect list built from proven buyer patterns, not generic title filters.

Lusha data is sourced and used in accordance with Lusha’s Privacy Policy and Terms of Use. Lusha is GDPR compliant and covers contacts across North America, EMEA, and APAC.

FAQ

  • How many seed buyers do I need?

    Use at least five seed buyers. Lusha lookalike contact searches require 5-100 seed contacts. You can use LinkedIn profile URLs, business emails, Lusha contact IDs, or name + company details.

  • What is the recommendation score based on?

    The score is created by ChatGPT using the Lusha data returned in the workflow. It is based on buyer match, ICP fit, recent timing signals, and actionability. It is a prioritization aid, not a prediction that the buyer will convert.

  • How is this different from a title search?

    A title search starts from a keyword. This prompt starts from real buyers who already fit your business, then finds similar contacts and explains why they may be worth targeting.

  • What kinds of seed buyers should I use?

    Use contacts who represent the buyer pattern you want to repeat: closed-won decision-makers, strong champions, expansion contacts, fast-moving opportunities, or contacts from accounts with high retention or high ACV.

  • Should sales trust the recommendation score automatically?

    No. The score should help prioritize, not replace judgment. The prompt keeps the score explainable so sales can see which data points drove the recommendation and decide how to act.
