There is a category of software business that rarely makes headlines but consistently produces exceptional returns: micro SaaS.

A micro SaaS is a small, often one-person software product that solves one specific problem for one specific audience. It is not competing with Salesforce. It is competing with the manual workaround that a specific type of professional currently uses because no dedicated tool exists.

The combination of AI development tools, no-code platforms, and lower infrastructure costs has made it practical for non-engineers to build functional software products. A founder with basic coding knowledge and AI assistance can build a working web app in weeks.

Simultaneously, the specificity that large software companies cannot economically pursue has left entire categories of professional workflow unsupported by good tooling. The niche that needs a specific solution and cannot find one is the micro SaaS opportunity.

Micro SaaS operates on a subscription model at $9–$99 per month. A product at $29/month with 200 subscribers generates $5,800 monthly recurring revenue — for a product that, once built, requires primarily maintenance rather than ongoing production.

The path to 200 subscribers for a product solving a genuine professional need in a specific niche is realistic within 12–24 months. The income produced is not speculative — it is contractual.

The biggest risk is building a product nobody wants. The mitigation is validation before building: confirming the problem exists, finding people who pay for existing workarounds, and pre-selling before investing significant development time.

AI development tools have reduced the cost of this validation significantly. A prototype sufficient to test a hypothesis can often be built in a weekend.

Micro SaaS offers recurring income with a specific ceiling that is achievable and a floor that, once established, is reliable. For those with product thinking and some technical access, it is one of the most capital-efficient business models available.
