Improving Company-People Linking in Database Setup

Question: I created a table to find companies. I then created a table to find people for these companies. At the moment there are a lot of people missing in the companies table. I'm able to find them manually and want to add them to the table. Sculptor suggests to add the Linkedin profile URL to the table, and Clay will then populate all the other rows. Unfortunately it doesn't work and I'm also wondering isn't there a better way so my setup remains organized eg. The people in the second table are linked to the same company on the first table
