How to Find and Categorize Nearby Companies in Clay Using Google Maps

Hello all, I need some guidance on what I’m trying to do in Clay. I have a list of current customer locations and addresses. Is there a way to look them up on a google map and then search for companies nearby that produce the same type of products? For example, the companies on our list manufacture boxes. How can I categorise this and set the right parameters in Clay to find the relevant nearby companies?
