Long-time lurker, first time posting. I work in investment banking and have been wanting to build a side income stream that’s completely separate from my day job. Last night I decided to actually do it instead of just thinking about it. Using AI vibe coding tools (Bolt, Claude, Cursor-adjacent workflows) I built and launched a full SaaS product in under 24 hours. No traditional coding background. What I built: HostAI — an AI concierge for Airbnb and short-term rental hosts. Hosts set up their property details once, share a link with guests, and guests get instant answers 24/7. No more midnight texts asking for the WiFi password. What I used: Bolt.new for the frontend and deployment Supabase for auth and database Claude API for the AI layer Stripe for payments Squarespace/Google for domain and email Honest reflection: The infrastructure stuff (Supabase, edge functions, getting the API key to stop breaking) was genuinely painful. Took way longer than the actual product. But it’s done now and the foundation is solid. Live at usehostai.com — 30 day free trial. Happy to answer questions about the build process or the tools I used. submitted by /u/magnoliaandco
