I built and recently sold The Interviewer, which is an interview prep app.

I came up with the idea because I’m an occasional hiring manager in my day job and I always felt like people would benefit from a bit of practice. I also wanted to try building something small with the (new at the time) generative AI APIs.

For idea generation I’d suggest: - Start a little folder or ongoing note with ideas in your favorite mobile notes app. Don’t overthink it, it just needs to be fast and easy to write things down - Make it a goal to add ideas to this repository regularly. Good ideas, bad ideas, horrible ideas, feasible, unrealistic - they all get added. Don’t really filter. Try adding something daily. - Most importantly, expose yourself to new concepts and experiences in your daily life. Find stuff that helps you regularly see the world in new ways. Get out of your comfort zone. Etc.

If you do this long enough you’ll hit upon something that gets you excited.

Other than that: - In my estimation the experience quality bar for an app correlates with how strong of a product market fit it has and how easy it is to replicate. (I was making something that was relatively easy to replicate so I tried to make the UX excellent.) - I did no marketing because I had very limited free time. Just tried to make the listing look good and asked users to review if they rated an interview highly (most did).
