This project came out of my own need. I’m a builder and struggle with the early stage of validating ideas with a relevant market. I’d browse Reddit and Yelp, but just wanted direct emails and that wasn’t an option via Yelp, so I found the emails myself for 4M+ US business listings on Yelp. Since this seemed valuable for other solo founders, I built SumoLists for anyone else that struggled with seeding early discussions and finding product market fit.
