Launch task after creating a record

I have a user table and then company data and candidate details, both conectect to the user table.
I need to have the company record ID on the user table so I can not load it when creating record as I could do with any other form record, since the ID does not exist until record is created. If I edit the record, then yes, it’s possible to load Record ID on user table. But idea is to do it automaticaly after creating company details record. Can anyone suggest how to do it?

I don’t see an option lo launch a task after creating record. Any idea?
