Buyer titles and excluded titles

Two lists on the Targeting page decide which people Clustr shows you, by job title.

List	What it does
Buyer titles	The job titles of the people you sell to, such as `CFO` or `Head of Finance`. When the list is not empty, anyone whose job title matches none of them is hidden.
Excluded titles	Job titles you never want to see, such as `Recruiter` or `Intern`. Anyone whose job title or LinkedIn headline matches one is hidden, even when they also match a buyer title.

An empty buyer-title list hides nobody. Each list holds up to 1,000 titles.

How a title matches

A title matches when its words appear in the job title, side by side or in the same order with other words between them. A match never starts in the middle of a word. Excluded titles match whole words only, so they never hide someone by accident:

Excluded title	Hides	Does not hide
`Sales`	Head of Sales, Point of Sale Manager	Salesforce Admin, Presales Engineer
`Media`	Head of Media	Head of Banking Intermediaries
`Intern`	Summer Intern, Interns Program Lead	International Payments, Internal Audit

Buyer titles also let their last word be the start of a longer word, so a list written as Sales Lead or Cyber keeps finding people:

Buyer title	Shows	Does not show
`Sales Lead`	Sales Lead, Senior Sales Leader	Lead, Sales
`Cyber`	Cyber Analyst, Cybersecurity Manager	Head of IT
`Director of Marketing`	Director, Global Marketing	Marketing Director
`VP Product`	VP Product, SVP Product, EVP Product	Vice President, Product

Capitals, accents and punctuation do not matter: AML matches “BSA/AML Officer”.
Singular and plural are the same word: Partner matches “Partners”.
Co-roles, feminine forms and compound titles count: Founder matches “Cofounder”, Président matches “Présidente”, Leiter matches “Vertriebsleiter”.
To match the start of a word in an excluded title, end it with *: recruit* hides “Recruiter”, “Recruiting” and “Recruitment”.
Buyer titles also accept a one-letter typo, such as “Marketinh”. Excluded titles never do.

When a change applies

A change applies to everyone already in your workspace within seconds. You do not need to run an import again. Nothing is deleted. A person hidden by a title comes back as soon as you remove that title. The lists also decide who your next ingestion runs bring in. Adding a buyer title today shows the matching people you already have, but it cannot show someone no run ever brought in.

From the API

With an API key:

	Buyer titles	Excluded titles
List	`GET /buyer-titles`	`GET /excluded-titles`
Add	`POST /buyer-titles`	`POST /excluded-titles`
Delete	`DELETE /buyer-titles/{id}`	`DELETE /excluded-titles/{id}`

Adding takes a keywords array, and a title already on the list is skipped:

curl -X POST https://api.clustr-ai.com/api/public/buyer-titles \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"keywords": ["CFO", "Head of Finance"]}'

From your AI assistant

The MCP server has the same six operations:

Tool	What it does
`list_buyer_titles`	List your buyer titles, with their ids
`add_buyer_titles`	Add buyer titles
`delete_buyer_title`	Remove one buyer title
`list_excluded_titles`	List your excluded titles, with their ids
`add_excluded_titles`	Add excluded titles
`delete_excluded_title`	Remove one excluded title

Ask, for example, “Add CFO and Head of Finance to our buyer titles” or “Stop showing me recruiters”.
