About me
I’m Jaemin Koo. For over a decade I’ve been starting, running, and partnering on small companies designed to compound — across hospitality, software, and design. My approach blends operating discipline with a long view: I’d rather build one thing that lasts twenty years than ten that last two. Most pages on this site are private; some are open.
