I grew up in Busan and spent my teens and twenties in San Francisco. I studied Cognitive Science at UC Berkeley. After graduating, I worked in data analytics and business development at a B2B SaaS startup, Gong.io.
I came back to Korea and started a company. Raised funding, built a team. But I quickly realized something: I'm not a founder who builds from zero. I'm closer to an investor — someone who spots existing innovation and allocates capital to it.
I didn't want money itself. I wanted the freedom money gives. Instead of trading my time for money, I needed assets that work while I sleep. The 4-Hour Workweek, Rich Dad Poor Dad, and The Almanack of Naval Ravikant shaped that thinking.
That search led me to Bitcoin. Not as a trade. As a shield against a monetary system that's changing. What Is Money? — The Saylor Series explained why.
Now I invest in Bitcoin and early-stage startups from Seoul. Lately I've been building things with Manus AI. This blog is one of them.
Interests
I'm drawn to moments when paradigms shift. Apple, Tesla, Bitcoin — looking back, everything I was pulled toward was on the side of a changing board. Finding the people and companies moving in that direction is what I find interesting.
I enjoy reading books. My highlights from everything I've read are here. If you've read any of the same books, reach out.
Why I write
To think clearly. Writing reveals what I actually understand and what I'm just assuming.
I publish it publicly because I think people with similar ideas will find it. If something resonated, get in touch.
