You should be able to reference text columns from your "find companies" table in your "find people" table. Clay automatically links these tables, allowing you to extract company attributes directly into your Find People table.
If you're not seeing the newly created columns, try re-running the company row in the people table. You may need to force run through the whole column to see the new values.
If the issue persists, check if your Find People table includes a lookup column that refreshes when changes are made to the Find Companies table. If you need further assistance, please request to talk to a person in this chat.
