Ask HN: How to find potentials users for my startup
2 by sanjogg | 0 comments on Hacker News.
I am currently working on a startup idea, and I would like to get some user feedback by people who have the problem I am trying to solve. How do I find people with a specific problem? (Apart from friends of friends or acquaintances). For example: If I was working on a solution for learning a language, how do I find people who are trying to learn a language?
