I'm Changhyuk Ban.

I build AI products from Korea 🇰🇷

Solo founder. No VC, no team, no bullshit. Inspired by Pieter Levels, I'm building multiple AI products in public.

Journey

• 2026.04 — Started mrban.io
• 2026.03 — Launched AtoZAI (Korean AI coding platform)
• 2026.01 — Started vibe coding

What I believe

• Ship fast. Ugly is fine.
• Build in public. Numbers don't lie.
• Solve your own problems first.
• Stay solo as long as possible.
• Korea has builders the world doesn't know yet.

What I'm not

• Not a marketing expert (I'm learning).
• Not a native English speaker (but I ship).
• Not VC-funded.
• Not doing this for exit. Just indie.
