Find Small SaaS Ideas You Can Ship Solo

Filter for buildability first

Every opportunity carries a build complexity rating and an estimated weeks-to-MVP. Filter to weekend or weeks builds and the list gets much shorter and much more actionable.

Then filter on distribution ease. As a solo founder you have no sales team, so a problem whose sufferers gather in one findable place is worth far more than a bigger problem scattered across an unreachable market.

Why narrow beats broad

A general-purpose tool competes with well-funded incumbents on every axis. A tool built for one specific workflow competes on the one axis where the incumbent is visibly failing — which is exactly what the complaint data shows you.

The vertical SaaS and micro SaaS categories are built for this. Both filter to problems where a general tool exists and is being used grudgingly.

Signals that a problem suits a solo build

• The workaround people describe is a spreadsheet, a manual copy-paste, or paying someone hourly
• The complaint names a specific step, not a general dissatisfaction
• The people complaining are businesses rather than consumers — a $49/month decision needs far fewer customers than a $5 one
• The same complaint appears on more than one platform, which usually means it is not an artefact of one community

The revenue maths

At $49 per month, a hundred customers is roughly $59k a year. That is a real income for one person and a rounding error to a funded competitor — which is precisely why the niche stays open.

The free calculators can pressure-test this before you build. The break-even calculator in particular will tell you very quickly whether the price you have in mind is plausible.
