Source: Read the reference persona
Turns one LinkedIn URL into a clean set of persona attributes the lookalike search can match on.
1. Source LinkedIn URL (Text input)
Entry point. The LinkedIn profile URL of the person you want to clone.
Example:
https://www.linkedin.com/in/frederic-mathieuOne URL per row. Use a converted prospect, a closed-won champion, or an ICP target
2. Enrich Source Profile (HTTP API POST)
Sends the LinkedIn URL to FullEnrich to pull the full source profile: title, seniority, industry, company and headcount.
Method: POST
Endpoint:
https://app.fullenrich.com/api/v2/contact/enrich/bulkAuto-run: ON when Source LinkedIn URL is not empty
Returns the structured profile used to build the search criteria.
3. Source Persona Formulas (Columns 3 to 7)
A group of formula columns that parse the source profile into the criteria the lookalike search needs:
Title → the source job title
Seniority → the source seniority level (VP, Director, Head, etc.)
Industry → the source company industry
Company Domain → the source company, excluded from results so you do not get the same person back
Headcount → the source company size band, used to keep matches at a comparable scale
Search: Find the lookalikes
Searches FullEnrich for people who match the source persona, then extracts the best matches.
4. FullEnrich Lookalike Search (HTTP API POST)
Searches FullEnrich's People Search API for profiles matching the source title, seniority and industry.
Method: POST
Endpoint:
https://app.fullenrich.com/api/v2/people/search
POST https://app.fullenrich.com/api/v2/people/search
{
"limit": 10,
"current_position_titles": [
{ "value": "{{Title}}" }
],
"current_position_seniority_level": [
{ "value": "{{Seniority}}" }
],
"industries": [
{ "value": "{{Industry}}" }
]
}Returns the top 10 matches ranked by relevance, all sharing the source role, seniority and industry but at other companies.
5. Lookalike Result Formulas (Columns 5 to 11)
A group of formula columns that parse each match from the search response into clean, usable fields:
Name → the lookalike's full name
Title → their current job title
Company → the company they work at
Domain → their company domain
LinkedIn → their LinkedIn profile URL
Each match becomes a row ready for enrichment.
Enrich: Final enrichment
Turns the lookalike list into an outreach-ready list with verified work emails and mobile phones.
6. Find Work Email (FullEnrich Native)
FullEnrich's native email-finding action, fed with each lookalike's identity:
Full Name →
{{Name}}Company Domain →
{{Domain}}LinkedIn URL →
{{LinkedIn}}
Returns verified emails with a confidence score.
7. Find Mobile Phone (FullEnrich Native)
FullEnrich's native phone-finding action, fed with the same identity. Returns a verified mobile number when available, so outreach is not limited to email.
8. Most Probable Email (Formula)
Extracts the highest-confidence email from the enrichment response for each lookalike.
Output: one clean, send-ready email per row
The workflow in action: the source profile is a VP Sales at a SaaS company that just closed → the persona reads VP, Sales, Software Development, ~200 employees → the search returns 10 VP Sales at comparable SaaS companies → enriched into a list of 10 prospects with verified emails and mobiles.
How to execute this workflow:
Drop a LinkedIn URL into the Source LinkedIn URL column
The source enrichment fires automatically and reads the profile
The Source Persona formulas extract title, seniority, industry and size
The FullEnrich Lookalike Search returns the top matches
The Lookalike Result formulas turn matches into clean prospect rows
Find Work Email and Find Mobile Phone enrich every row
Filter on found emails and push the list to your CRM or outreach sequence
When to use this template:
Clone converted prospects into a fresh list of similar buyers
Expand a working ICP from one strong example profile
Post-event prospecting from a single great connection
Territory building when you know the persona but not the names
One good profile in, a full enriched lookalike list out. Re-run with a different source whenever you find a new winner.
