How I work
A small studio with simple rules
Live every weekend
Ship, then polish. Every weekend ends with something you can open and use, not a plan in a document.
One person, plus AI agents
AI agents write, test and deploy the code, then report back to me. I pick what we build and sign off on anything that touches money or your data.
About
Hi, I'm Min.
I'm Min Tun, the founder of SoeSan Holdings. I don't come from a software background. I spent more than 12 years at Dunkin', starting as a crew member in 2007 and working up to store manager, and I taught myself to build software on my own time. I spend my spare time on history, space and tech, which is why the work above includes an eclipse planner, a satellite tracker and a history game.
In October 2026 I started building in public with a team of AI agents, and we've shipped 24 products since. Now I'm doing the harder part: building a real business, one product at a time, starting with Pennyrow.
Let's talk.
The quickest way to reach me is a message on X. New builds show up there first, too.
