Niche micro-SaaS

Ship a small, focused web app for one underserved audience.

A micro-SaaS solves one painful problem for a specific group (e.g. invoicing for tattoo artists). AI coding tools let one person design, build, and launch a real subscription product in weeks.

How it makes money: Monthly subscriptions; a first goal of 100 users × $20/mo.

The opportunity

How it works

A micro-SaaS solves one painful, recurring problem for one specific group — invoicing for tattoo artists, scheduling for dog groomers — instead of competing with broad tools. AI coding assistants now let a single person design, build, and ship a real subscription product in weeks instead of months, so the bottleneck moves from coding to picking the right problem. You grow by hand-onboarding your first ten paying users and letting their feedback shape the roadmap. Revenue compounds slowly but is sticky: a focused tool people rely on daily rarely gets cancelled.

Reality check

Challenges to weigh

  • Picking the wrong niche is the number-one killer — validate that people will actually pay before you build.
  • Even with AI you own support, billing, bugs, and security; a SaaS is a long-term commitment, not a one-off.
  • Distribution is now harder than building — you need a real plan to reach your niche, not just a working app.
