Built with Claude · Second edition 2026
From Idea to Shipped in 20 HoursBuild, launch, and sell solo with AI
How a solo founder builds production-ready SaaS, marketplaces, and online shops with Claude. The guide, the templates, and the complete boilerplate code — auth, payments, email, legal, deployment, everything in. Plus the infrastructure that keeps it alive: a public API and an MCP server so AI agents discover and use your product, a „no-hardcoding“ standards discipline, four-tier gating, and a complete EU-sovereign migration path.
Three tiers: €19.99 (E-Book) · €69.99 (Templates) · €99.99 (Boilerplate) — or bundled for up to 12% off
What's inside
Five chapters that matter after launch
The "No-Hardcoding" Discipline
Single-source patterns, pre-edit hooks, a verify gate, and a legacy "ratchet" — the machinery that keeps a solo codebase honest. Includes a real audit of the boilerplate.
API & MCP Infrastructure
A tier-based REST API + MCP server so AI agents discover and use your product. openapi.json / llms.txt as the new sitemap.
Four-Tier Gating
free / registered / pro / elite — server guard + UI hook from a single source of truth, with a generic feature matrix to adapt.
Production Patterns
Append-only audit logs, region pinning around geo-blocks, upstream license audits, content embeds — resilience that fails loud, not silent.
EU-Sovereign Rebuild
Migrate the whole stack to EU providers — with honest cost/maturity/DX trade-offs per building block. GDPR by architecture, not just on paper.
The unvarnished version of the story
I built tradingstrategies.work in 70 hours, alone. With all the dead ends, all the wrong decisions, all the learn-as-you-go.
Those 70 hours are now available as the guide, the setup templates, and the finished boilerplate code. With Tier 3, you need 20 hours max — because the foundation is built, and you just plug in your own product.
Not a marketing claim. The difference between 70 and 20 hours is the gap between learning as you go and starting from a proven foundation.
This book goes a step beyond shipping: it documents what keeps the product maintainable, discoverable by AI agents, and defensible under EU law once real users arrive — the things that decide whether month twelve is still fun.
Three tiers, three paths
Pick the package that matches your situation. Tier 1 to learn, Tier 2 to ship with Claude Code, Tier 3 to launch directly. Or combine as a bundle and save.

What you don't get
So you know what you still have to bring yourself:
- −Your specific product idea. What your SaaS does is your job.
- −A lawyer for serious legal questions. The legal templates are templates — not legal advice.
- −Business decisions. Tier 1/2/3 helps you build, not market.
- −Branding and logos beyond an accent color.
- −Lifetime updates. Second edition, 2026, one-time purchase.
