Jiu Jitsu Sans Frontieres is a social network founded by Viking Wong, it focuses on the open source development of all grappling arts. The JJSF network is free for all successful applicants. We aim to follow the original practice and philosophy of the gentle art, with an emphasis to restore moral values to build better characters in human beings. We will never cease to explore new innovations to challenge ourselves.

Our goal is to give our members the opportunity to cross train with everyone in a stress-free environment, where techniques, ideas and business opportunities can be developed through our open source network. As a Jiu Jitsu focused company, we also provide services such as uniquely tailored curriculums and certified rank advancements for start-up school owners. 

Our members are very important to us. We will do our best to treat you with fairness and the respect you deserve. We simply ask the same consideration from you. Everyone comes from a unique background with different Jiu-Jitsu goals. Our goal is to provide an environment that will help you reach them. There are currently 2 types of memberships, Tier 1 & 2; both providing a solution that caters to everyone.
