SocLeads 2.0▲706It's my first time launching my own SaaS. I planned to develop it with a friend, but he refused to work with me because his developer skills are higher (in his opinion). I developed a simple online email scraper by keyword, hashtag, or followers using Google Search as a source of data (with Dorks) I will be glad to receive any feedback and suggestions.
