Successful Micro SaaS Examples

A source-backed comparison of small software companies. Public revenue figures are dated, and unknown numbers are clearly labeled instead of estimated.

Evidence before inspiration

Compare the evidence behind each example

Revenue changes quickly and many founders keep it private. We use first-party company or founder sources, preserve the date and context of each disclosed milestone, and label missing figures as undisclosed. “Source checked” means we reviewed the linked page on that date; it does not imply a fresh revenue update.

How to read public SaaS numbers

  • Milestone is not current revenue. A dated founder post proves the company reached that figure then, not that it earns the same amount today.
  • MRR and ARR are not cash collected. They normalize recurring subscriptions and may handle discounts, taxes, refunds, and delinquency differently.
  • Undisclosed is a useful answer. Customer count, profitability, longevity, and team size can validate a business without a public revenue number.
  • Stack details expire. We only show a stack when the cited source supports it; otherwise the field stays unknown.

Frequently asked questions

Are these current revenue numbers?

Only Simple Analytics exposes a live revenue dashboard in this comparison. Other public figures are dated milestones, and each card states the source context.

Why are some revenue amounts undisclosed?

Because the company has not published a first-party amount we could verify. We do not convert customer counts, team size, or third-party estimates into invented MRR.

What should a founder copy from these examples?

Copy the research pattern: narrow problem, clear buyer, pricing model, and repeatable acquisition channel. Do not copy a product or treat an old revenue milestone as a forecast.
