Best Methods to Build a Franchisee Lead List and Contact Info

Hey! I’m trying to figure out the best way to build a franchisee lead list — specifically for identifying individual franchise owners and getting their contact info. One question I have: Is there a way to pull contact details from a Google Maps link (like for a location of a franchise), or is there a better method/tool that you’ve used before? If anyone has done something like this or has tips, I’d really appreciate your insight!
