About

Giyeol Bae
Giyeol BaeFounder

Product engineer with 10+ years of experience. I started Groundcode as a solo product studio in late 2025 and have built and operated 19 products end-to-end across product, engineering, design, and operations. Recent launches include the location-based reward mini-app Money Trail and the standalone knowledge site sangsik.kr. I run Toss mini-apps and web products against real usage, retention, and unit-economics data, turning ideas across AI, utilities, and consumer apps into products that can be tested in the market.
