The cost of building software has dropped faster in the last two years than in the previous decade. AI coding tools and no-code platforms have made it possible for a solo founder to build, launch, and grow a micro-SaaS — a focused software tool solving a specific problem — in weeks rather than months.
Step 1: Find the Right Problem
The most common failure mode for micro-SaaS isn’t technical — it’s building something nobody needs badly enough to pay for. Look for problems that are recurring, specific, currently solved expensively, and in a domain you understand.
Source for finding problems: Read community forums and product reviews for your target industry. Look for recurring complaints about existing tools.
Step 2: Validate Before Building
- Landing page test: Build a landing page, run $100 in targeted ads, measure sign-ups. Benchmark: 5%+ conversion suggests real demand.
- Manual first: Solve the problem manually for 3–5 early customers. Understand the full solution before automating.
- Direct outreach: Message 20 people in your target market. Five honest positive responses is stronger signal than 100 landing page sign-ups.
Step 3: Build With AI Tools
- UI/Frontend: v0.dev or Cursor for React development
- Backend: Supabase for database and auth
- AI features: OpenRouter for model access
- Payments: Stripe for subscriptions
A technical solo founder using AI coding tools can build a working MVP in 2–4 weeks.
Step 4: Price and Launch
Target $19–99/month per user. Avoid free tiers until you have product-market fit evidence — free users rarely convert and consume support resources. Launch first to your validation list.
Realistic Expectations
50 customers at $29/month = $1,450/month recurring. That’s meaningful side income that can grow. The goal isn’t to build the next Salesforce — it’s to build something small that generates income predictably and compounds over time.
