90% think SaaS needs millions in venture capital. The other 10% build micro-SaaS with no-code and AI – solo, from home, €50–500/month running costs and €2,000–20,000 MRR.
The problem: you want a software company but you're one person.
Classic SaaS: find idea, build team, hunt product-market fit, Series A… 90% fail.
Micro-SaaS plays a different game:
- One product, one problem, one niche
- One founder (you), no employees
- Low costs (€0–500/month)
- Profit possible from day one
- AI and no-code cut effort ~80%
Reality check:
- Global SaaS market ~$307 billion in 2026
- Micro-SaaS (€1–100k MRR) fastest segment at 31% CAGR
- 50 customers × €49/month = €2,450 MRR = €29,400/year
- No-code cut dev cost from €50k+ to under €500
- AI agents can automate 60–80% of build work
Barrier is near zero. Execution is everything.
What is micro-SaaS?
Micro-SaaS = small software-as-a-service solving one specific problem for one specific audience.
Traits: one thing done extremely well, small codebase, solo founder, low fixed costs, profitable with dozens of customers, recurring revenue.
Examples: Plausible Analytics, Buttondown, Carrd, Typefully – or a tiny tool for photographers' Instagram bios at €5 × 200 users = €1,000 MRR.
Most successful micro-SaaS look boring. They solve a small problem well – and get paid.

Truth about micro-SaaS
- First 90 days are hard – you'll build unused features; stay minimal
- Churn is the enemy – 5% monthly churn needs 5% new just to stay flat
- Support takes time – 2–4 h/week even at 50 customers
- Hardest part is GTM – find, sell, retain
Winners: talk to customers before building, launch fast and ugly, one niche, retention > acquisition.
Conclusion
Five years ago: €50k and 6 months for an MVP. Today: €50 and 3 weeks.
Tools, AI, and infrastructure exist. The question is which problem you solve – and for whom.
Micro-SaaS isn't get-rich-quick. It's a real model that works if you start, learn, iterate, and persist.
In 6 months you can have €2,000–10,000 MRR – or wish you'd started.
