Micro-SaaS

Micro-SaaS is a small software-as-a-service business built and run by one person or a tiny team, serving a narrow niche with focused functionality. Think a single sharp tool for a specific workflow, not a sprawling platform. The revenue is recurring, but the ambition is modest by design: a profitable, low-overhead business rather than a venture-scale rocket.

Why founders love it: the economics are forgiving. Subscription revenue compounds, the support load stays manageable because the scope is small, and you can stay solo far longer than a broad product would allow. It suits a portfolio approach, where several micro-SaaS products each clear meaningful revenue without any one needing to be a unicorn.

What it looks like in practice. Say you're building a tool that lets agencies schedule client reports: you run the whole backend, auth and database on Supabase, so you never staff an ops team. Your marketing site is a single page in Webflow that you edit yourself between support tickets. And because retention is everything in a narrow niche, you drip onboarding emails through Brevo to get new users to their first win before they churn.

The constraints are real. A narrow niche caps your market, so pricing and retention matter more than raw growth, and distribution is the hard part while the product is usually the easy part. You win by owning a problem a defined group feels sharply and would happily pay to remove.
