Hi, I’m Hyein
I didn't start with a marketing degree or big agency background. I started with curiosity — testing ideas that led to a campaign costing just $0.10 per offline visitor, driving 2,500+ people, and winning 1st Prize from the Korean Publishers Cooperative.
Since then, I've helped mission-driven brands crack the code of Korean and Japanese markets. In my first year of freelancing alone, I built a $100K business managing 3 brands across 3 languages — all because I understood one thing: culture drives conversion.
That's why I built HY Marketing as a boutique agency that works with a limited number of clients per market, ensuring every campaign gets the focus and cultural insight needed to win.
