I built a B2B AI SaaS in 4 months using ONLY a 4GB Android phone (0 coding). Today we are live! 🚀
Hey everyone!
Most founders here have insane tech stacks, dual monitors, and perfectly optimized setups. I had a very different reality.
Over the last 4 months, I built my startup entirely from scratch without a computer. I structured, prompted, and put together every single piece of the app using only a 4GB RAM Android phone and I had zero programming experience before starting.
Today, that wild experiment is live on Product Hunt.
It’s called Domin.ai — a real-time AI sales co-pilot. It’s designed to help founders and sales teams crush complex, high-ticket objections instantly via WhatsApp.
Building this strictly from a small smartphone screen forced me to be hyper-focused on simplicity. It made me cut the noise and focus only on a clean, minimalist UI and a core feature that actually drives revenue.
I’d be incredibly honored if you could check out our launch today, see what a solo founder built from a phone, and drop some brutal, honest feedback in the comments.

Thank you for supporting bootstrapped solo founders! 🙏

no computer at all for 4 months is the part I can't picture. what were you actually using on the phone to write and deploy the code, some cloud IDE, or was it all through an AI builder's chat interface with zero direct code editing on your end?
