THE PERSON BEHIND KUMABITS

A business mind.
A builder’s hands.

I’m Vicente Berbegall. Engineer by training, commerce leader by experience, and still someone who likes to build.

Today I’m CTO at Decathlon Japan. KumaBits is my independent home for the work and ideas that connect those parts of my life.

SELECTED COLLABORATIONS

Good conversations
are a starting point.

A difficult technology decision, an interesting system, or an idea worth exploring. I’m open to a focused conversation when there is a good fit.
