These lean, nimble products solve small but ubiquitous problems, earning strong recurring revenue with minimal overhead. Curious how disciplined simplicity can pay off big? Let’s dive into five niches where modest apps are turning into money machines.

#### Final Thoughts

If there's one lesson from these stories, it's this: you don't need to chase the next billion-dollar unicorn to build something meaningful. Micro SaaS founders are proving, time and again, that solving small, overlooked problems can snowball into life-changing businesses.
