I read a lot of articles and posts on social networks regarding startups and how you should start your project to be successful. Almost every founder is advising to find one pain point and give a solution. Even if there are bunch of competitors geometry vibes, you need find one pain point and solve it in your product according to advises.

That’s clear for me, how can I find that one pain point or problem shared by a group of people? Where should I look for the pain points of potential customers? Does anyone have an algorithm or a step-by-step framework for this?
