Micro SaaS
Level 4
Sell small software that solves a narrow problem, on subscription. The longest route and the highest failure rate — and the only band where revenue arrives in a month you did not work.

We have zero verified cases for this model, so no revenue range is shown. Publishing a figure without evidence is not something we do.
Who you sell to
- A specific profession
- Small operators
- A narrow group with one shared problem
How the money comes in
- Monthly subscription
- Usage-based billing
Steps
- Pick one friction in work you already know
- Build the smallest version and put it in front of ten people
- Ask whether they would pay — using and paying are different
- For expensive generation, consider having users bring their own API key
Risks
- The stretch before first revenue is long, and you need to live on something during it
- Selling is harder than building — engineers fall into this one hardest
- If a general model absorbs the feature, the product is replaced wholesale
- Products with a dozen subscriptions are commonly listed for sale — that is the reality of this band
