Solo SaaS ideas for solopreneurs
Small software, big leverage: where solo founders find SaaS ideas that pay.
Where solo SaaS ideas come from
- App marketplace reviews: one-star reviews of popular apps list missing features.
- Your own job: the spreadsheet everyone in your role maintains could be a product.
- Integrations: connecting two tools a niche already uses.
Patterns that suit one person
- A narrow audience that will clearly pay, usually businesses rather than consumers.
- Low support burden: self-serve onboarding, no custom work.
- A channel you control, or a marketplace that sends traffic.

How to choose between these ideas
Score each idea 1–5 on four questions and start the one with the highest total:
- Can you get paid in 30 days? Services usually beat products here.
- Do you already have the skill? Learning and selling at once doubles the risk.
- Do you know where buyers gather? A community, marketplace, local street or your old industry.
- Could it run on 5–10 hours a week? Most people start alongside a job.
Then validate before spending money: see how to test a business idea.
