I've tried a couple of startups over the past several years, one consumer and one a b2b SaaS company. The first one had no clear business model and was more of a side project to learn to code. I hoped to turn it into a startup but in hindsight it really never had a chance. The second had a clear business model but didn't target a specific niche and ultimately had no differentiators or compelling value proposition.
I'm at a point where I don't know what to do next. Nothing jumps out at me as a clear problem that needs solving, or a "scratch your own itch" type situation. My entire motivation to learn to code was to start a startup, and I can't figure out what to do next.
Where do I go from here? How do I find an idea and convince myself that it's good enough to move forward with?
