Choose and Validate Your SaaS Idea

2-3 daysRequired

Pick a problem you've personally experienced. Use AI to analyze competitors and market gaps. Post validation threads on Twitter/X, Reddit, Indie Hackers.

List 3-5 pain points you've experienced personally
Use Claude/GPT to analyze each idea's competitive landscape
Build landing page with 'Join Waitlist' button
Goal: 50+ email signups or 3 paid pre-order intents in 72 hours

Choose Tech Stack and Set Up Project

1 dayRequired

Pick the simplest stack. Recommended: Next.js + Supabase + Vercel (zero-config deploy) or Cloudflare Workers + D1 (zero cost).

Install Cursor, configure AI models (Claude Sonnet recommended)
Run npx create-next-app or wrangler init
Configure Supabase: database + Auth + Storage
First deploy to Vercel/Cloudflare, verify CI/CD pipeline

Build Core Features (MVP)

7-10 daysRequired

Build only 1-2 core features. Use Cursor Agent mode to describe requirements and have AI generate ~80% of the code. Deploy daily.

Build database schema first, then API, then frontend
Cursor Agent workflow: describe feature → review code → test → deploy
Deploy at least once daily to keep it demoable
Core principle: cut features, not quality

Integrate Payments and Handle Edge Cases

3-5 daysRequired

Add Stripe Checkout (AI can generate the code in ~30 minutes). Handle errors, add monitoring, polish UX.

Stripe Checkout integration with webhook handling
Add Sentry error monitoring (free tier)
Email notifications: Resend free tier (3,000/mo)
Basic security: rate limiting, input validation, CORS config

Prepare Launch Assets

2-3 daysRequired

Write product descriptions, take screenshots, record demo video. Set up Product Hunt page, Twitter thread, final landing page.

3 versions of product copy (50 words / 200 words / 500 words)
Product screenshots (3-5) + 30-second demo video
Product Hunt page (set up 1 week ahead)
SEO basics: meta tags, Open Graph, sitemap.xml

Launch and Get First Users

1 day (launch) + ongoingRequired

Launch simultaneously on Product Hunt, Twitter/X, Hacker News, Indie Hackers. Build in Public: share revenue and user data openly.

Product Hunt launch (pick a weekday, avoid major launch days)
Twitter/X: share the complete 0-to-launch journey
Hacker News Show HN post
Be online 24 hours on launch day to respond to all feedback

Iterate and Grow

Ongoing (day 31+)

Iterate based on real user feedback. Focus on retention > acquisition. Start building SEO content and community presence.

Daily check: user feedback, error logs, conversion funnel
Ship 1-2 most-requested features per week
Start writing SEO blog posts (AI-assisted, 1-2 per week)
Monthly review: revenue, users, retention, next steps

Warnings & Tips

96% of projects won't be profitable

Only 4 of Pieter Levels' 70+ projects succeeded. Don't invest more than 30 days in any single idea. Set a hard stop: no paying users in 30 days = pivot immediately.

AI code is NOT maintainable code

AI-generated code may run perfectly but hide security vulnerabilities and architectural debt. PhotoAI's 40,870-line single PHP file makes money but can't be handed off. Security-critical sections (auth, payments) MUST be manually reviewed.

Thin wrappers are a dead end

If your product is just a frontend for an LLM API, the model provider can launch a competing feature anytime. You must build proprietary data or workflow layers on top, or your moat is zero.

LLM API costs spike with user growth

GPT-4o output costs $15/M tokens, Claude Sonnet $15/M tokens. 1,000 active users making 10 calls/day = $300-500/month in API fees alone. Set spending limits and implement aggressive caching from day 1.

Over-engineering is the #1 enemy of indie devs

A product with 0 users doesn't need Kubernetes, microservices, or complex architecture. Pieter Levels runs $105K/mo on a single PHP file. Simple = fast = more attempts = higher success probability.

Highlights

AI multiplies dev productivity 5-10x

Cursor Agent mode + Claude Code lets one person do what previously required a team. Pieter Levels now barely writes code himself, relying entirely on AI assistance.

Zero-cost startup is genuinely possible

Cloudflare Workers + D1 + Vercel Hobby + Stripe is completely free at 0-1,000 users. You pay infrastructure from revenue as you grow.

Battle-tested methodology

Based on real experiences from Pieter Levels ($420K/mo record), Marc Lou ($116.9K MRR), and other successful indie hackers — not theoretical advice.

Honest about the 96% failure rate

Doesn't sugarcoat that only 4 of Pieter Levels' 70+ projects ever made money. Teaches you how to improve your odds, not guarantee success.

Complete 30-day roadmap with daily deliverables

4-week plan from validation to launch with specific deliverables and go/no-go criteria each day. Not vague 'suggestions' — actionable steps.

Distribution strategy > Product strategy

Explicitly addresses that in 2026, the competitive moat is distribution, not product. Teaches Build in Public, SEO, and Product Hunt launch tactics.
