Ask HN: Founders, what was the major sourcing channel for your first 100 users?

Idk other platforms but you can try Rappo https://www.buildrappo.com/… I tried LinkedIn to reach out customers but the response rate is way low. I don’t want to spend too much on customer research so I tried Rappo as one of my colleague referred to me.

LinkedIn is indeed a tough place to have a talk with customers, even though it has great amount of people. This buildrappo sounds like a good option.

Sorry, I have shared a broken link. https://www.buildrappo.com/founders/ For founders
