will using the find people feaature cost credits?

No, using the Find People feature for list building/prospecting is free. You only pay credits for data enrichment actions like finding contact information or retrieving firmographic data. For example, you can build lists from LinkedIn, Google Maps, GitHub, CRMs, and websites without using credits. Credits are only charged when you enrich the data with additional information.

Hi Nicolaos, The find people functionality will not cost credits. Finding people (and companies) on Clay is a free functionality and only information that comes from third party providers such as finding emails will charge you Clay credits. Let me know if this is not the case on your end.
