Ask HN: How do you know what to build to peaople want this?
The best startup advice is build something what people need. How do you know what it is? Are there any strategies to get to know what people need?
this is usually called finding product market fit or validation stages and each person will approach it slightly differently, but generally what (in my own opinion) works best is:
1) do something that doesn't scale to see if people need it. want to create a mental health app? start by talking to people in mental health-adjacent subreddits etc.
2) build something that solves your problem, then show it to others to see if they faced the same issue, this is usually more 'fun'
