How to create a List of Contacts that have an associated Lead?

[EChapman]

We are trying to do a removal of any Contacts on our system that do not have an associated Lead - I have tried the guidance below but cannot find the 'Number of Associated Leads' property mentioned. Is there a way to create a list or filter on the Contacts page to see this?

Thank you!

Hi @EChapman,

Is this a generative AI answer? If so, this looks like AI hallucinating.

Here's a quick way to achieve what you're trying to do:

1. Create a contact-based list that filters for contacts associated to leads:
   1. Click 'Add filter'
   2. Change 'Filtering on' dropdown from Contact to Lead
   3. Pick any property value available for each lead, e.g. 'Create date is known'
2. Save the list
3. Create a second list of contacts who are not a member of the first list, these are the contacts without associated leads

Alternatively, you could create a custom roll-up property that counts associated leads: https://knowledge.hubspot.com/properties/create-calculation-properties
