When he asked me to help him, he had already spent a few months vibecoding the landing page and then got stuck in the payment infrastructure and the database to track purchases, returns, etc. When I looked at his vibe coded app, it was a nightmare, all routes broken, api calls sync, event loops booking, etc -> then I realized, vibe coding is great only if you know what you are building in a technical sense. It took me 2 weeks to fix his app and set up the infrastructure - while doing it from scratch could have only taken a few days.
That is when I realized, what if we train an AI to be a software engineer and then that AI do the building, review, and shipping! I spend few month part time working on it and created the first version last summer, soon it started to grab attention, people started assigning an idea to it and walked away, the agent then built most of the app and asked for feedback when was needed - initially it had memory and planning performance issue and I spent the next 4 months optimizing it and re-launched early this year.
In a few weeks after launch, I got tons of requests for adding automatic marketing and sales agents - so I added email campaigns, Meta ads, LinkedIn outreach, and AI viability agents in the next few months. When I closed the loop, a user could bring an idea, Leapd would build the app, and launch marketing campaigns to bring customers, all on autopilot.
The stack I used is: Vercel for frontend deployment, AWS for backend, Stripe for payment, Postgres/RDS, and S3 for database. And Claude for running sessions and coding + custom agents that do the actual tasks - happy to share more if anyone is interested.
