Hey everyone, my name is Kubilay “Kubi” Demirhan — I’m a full-time Jiu Jitsu coach and active competitor.

This December, I’ll be competing at the IBJJF World No-Gi Championships in Las Vegas — one of the biggest tournaments in our sport.

Jiu Jitsu has given me everything — discipline, brotherhood, purpose. I’ve devoted my life to teaching kids, mentoring teens, and volunteering with organizations like the New Haven Police Activity League, helping at-risk youth find strength on the mats instead of the streets.

Competing at Worlds is more than personal — it’s a chance to represent our community and prove that hard work, heart, and discipline still win.

Your support covers travel, registration, housing, and bringing my coach with me — the essentials that make this dream real.
