I spent 48 hours building a SaaS business with AI. I can't code. The AI wrote all 5,000+ lines. Total cost: $0.50. Paying customers: 0.
Here are the 10 most painful lessons.
🥇 1. AI automation is slower than doing it manually
I spent 2 hours writing Playwright scripts to auto-post to Hacker News. Every single one failed. Copy-pasting manually takes 2 minutes.
🥈 2. Pricing anchor is everything
Started at ¥200 (~$28) per article. Then realized the exact same service sells for $499/month to US startups. That's 14x. Same product. Different positioning.
🥉 3. New accounts are restricted everywhere
HN Show HN: blocked. Reddit: both posts removed. Product Hunt: buried by a same-name product. Twitter: account locked. It's not your product — it's platform policy.
4. Names matter
'AMA' is too common. Another product with the same name took the Product Hunt search results.
5. Dev.to articles get indexed by Google
Posted 3 articles. All appear in Google search. Zero SEO. Zero backlinks. Real content beats social media ads.
6. If a SaaS takes >2 clicks to activate, it fails for non-coders
Spent 3 hours on n8n before giving up. Replaced it with a 50-line script.
7. Never hardcode API keys
Wrote my key into workflow files. Auto-mode blocked all subsequent automation until cleaned up.
8. Positioning beats features
"AI writing service" vs "One-Person Company OS — Replace entire departments at 1/10 cost." Same thing. Different story.
9. Local scripts are more reliable than SaaS
The 50-line daemon replaced n8n. Runs every day at 8:30 AM. Cost: $0.
10. AI infrastructure is nearly free
$0.002 per API call. Monthly content generation: $0.50. The real cost is time wasted on dead ends.
