Building one SaaS is hard. Building five in two weeks sounds insane. But here is how I did it — and why the portfolio approach works.
The Portfolio Strategy
Instead of betting on one product, I built five complementary tools targeting EU compliance and developer tools. Each product uses the same tech stack (Next.js + Vercel + Stripe), has a free tier, and cross-promotes the others.
The Five Products
1. AccessiScan — WCAG Scanner
Problem: EU businesses face fines up to 600K euros for non-accessible websites
Solution: 201 WCAG checks in 60 seconds. Free 3 scans/month, paid from $9/mo.
2. CaptureAPI — Screenshot API
Problem: Managing headless browsers for screenshots at scale
Solution: One API call for screenshots, PDFs, OG images. 200 free/month, from $9/mo.
3. CompliPilot — AI Act Compliance
Problem: AI companies don't know if they comply with the EU AI Act
Solution: 200+ automated compliance checks. Free 3 scans/month, from $29/mo.
4. DocuMint — PDF to JSON API
Problem: Manual data extraction from PDFs costs thousands of hours
Solution: One API call, any PDF, clean JSON. 100 free pages/month, from $19/mo.
5. ChurnGuard — Payment Recovery
Problem: Failed payments cause 20-40% of SaaS churn
Solution: Automated 3-step dunning. 30-50% recovery rate. Free plan available.
The Shared Stack
Every product uses: Next.js 16, TypeScript, Tailwind CSS, Vercel, Stripe, Upstash Redis. Write auth once, billing once, deploy pipeline once — reuse across all five.
Timeline
- Week 1: Core functionality for all 5
- Week 2: Pricing, Stripe, blog content, SEO
- Week 3: Marketing — 100 cold emails, 50+ directory submissions, blog posts
Cost to Build
About $60 total: 5 domains. Everything else on free tiers.
Revenue So Far
Zero. But the infrastructure is live, products work, and the marketing flywheel is spinning.
Also Built
ToolKit Online — 143+ free online tools (calculators, converters, developer tools) in 6 languages. The SEO traffic engine.
FAQ
Why five instead of one?
Diversification. If one market fails, others might work. Shared stack means low marginal cost per product.
When do you expect revenue?
Within 2-3 months. Products need SEO authority and outreach conversion time.
Are you using AI to build?
Yes. Claude Code for development, AI for content drafts (human-edited). Strategy and business logic are human decisions.
