Exploring Ways to De-Anonymize Reddit Usernames with Clay

Hello everyone, is there a way to de-anonymize usernames on reddit using clay? i am looking for company names behind a certain set of usernames on reddit. i know reddit works in shadows and it's pretty hard to do this but still might there be a way? one idea i had was to take the usernames and scrape their profiles for all the posts and comments and see if they mentioned their company somewhere. but this is a monumental tasks that will be costly and still yield low confidence results. would appreciate if anyone has any ideas.
