Designed From The Ground Up.
From early concepts to polished prototypes, every detail was carefully refined.
Built From a Frustration.
Every macro keypad I tried made me change the way I worked.
I didn't want another device that forced compromises, I wanted one that adapted to me.So I started designing my own.
What began as a personal side project turned into more than a year of hardware iterations, software development and countless prototypes.
I built K101 because I wanted it on my own desk. Now I'm excited to share it with yours.
