I've been a software engineer for over 5 years now and have worked on various greenfield and brownfield projects. I want to branch off and spend the next 3 months building a MVP SaaS product. Every post I read says it's all in the execution and effort, and the idea is nearly irrelevant. Assuming these posts are correct, the next step for me should be to find a reliable and safe product idea and simply execute better than the competitors (or find a pain point they've yet to solve.)
I'm still quite skeptical about this approach, but I'll ask anyways: if the idea is not that important, then what are some safe and reliable SaaS ideas?
