About
I'm the CEO of Tetra and GP of 조약돌개인투자조합, working hands-on with early-stage Korean startups — from incorporation to early fundraising and first product validation.
My career started in PE at ORIX Corporation in Tokyo, moved to venture investing at BonAngels Venture Partners, one of Korea's leading early-stage VCs, then to PUBG/KRAFTON where I led Corporate Development and new business at global scale.
Today I bring that background directly to founders at the earliest stages — when building the first team, raising initial capital, and validating the first product matters most.
Through Tetra (studio), 조약돌개인투자조합 (fund), and this site (perspective), I put what I've learned into practice.
