ABOUT

MOON KIM

I started with code. Now I build systems for growth.

I began my career as a developer. Today, I am a growth product consultant and the founder of YNF. I connect technology, data, and AI to turn strategy into products and systems that work.

01 / THESIS

A Seoul workspace combining code, analytics, and system diagrams

Strategy should work in the real world.

To me, growth is not a one-off campaign. It is the work of defining the right problem and connecting product, data, and automation to produce repeatable outcomes. My background as a developer means I can go beyond recommendations and build the systems the work requires.

YNF began with a personal desire to live more freely. Today, I am building products and experiments around a broader belief: AI can become basic infrastructure that helps anyone work and live with greater freedom.
