Build an AI SaaS Side Project: Idea to First Revenue

Building an AI SaaS is one of the most scalable side hustles. A single developer can build and launch in weeks.

Step 1: Find a Real Problem

• Talk to 10+ potential users
• Search for existing solutions, read negative reviews
• Check if people pay for inferior solutions
• Create landing page, gauge interest

Step 2: Choose Tech Stack

• Frontend: Next.js or Astro
• Backend: API routes or Express
• Database: Supabase or PlanetScale
• AI: OpenAI/Anthropic API
• Payments: Stripe or Lemon Squeezy
• Hosting: Vercel or Cloudflare

Step 3: Build MVP

Do ONE thing well. Timeline: Week 1 setup + core, Week 2 polish, Week 3 payments, Week 4 launch.

Step 4: Pricing

Free tier + one paid plan. $9-$29/month for individual tools. Offer annual discounts.

Step 5: Launch

Product Hunt, Hacker News, relevant subreddits. Gather feedback, iterate quickly.

Realistic Expectations

• $0-$500/month initially
• $1,000-$10,000/month within a year for successful projects
• Most projects fail — treat as learning
