In Bourg-la-Reine, just south of Paris, the Brazilian jiu-jitsu section of the ASBR sports club goes by a three-letter name: BLR. Created in 2015, the team now gathers 200 members, a kids program, and a share of competitors most clubs can only dream of: 60% of the members compete, and one of them wears the colors of the French national team (CFJJB).
Leading this collective is Kenji Sette-Matsushima, a 3rd degree black belt, supported by teammates such as Arnaud and Reda. And to run a structure this size without losing his evenings to admin, the team relies on OSS Academy.
A team born inside a multisport club
BLR is not a classic private academy: it is the jiu-jitsu section of ASBR, Bourg-la-Reine’s multisport club. That associative setting gives the project a distinct identity, rooted in local life.
Since 2015, the team has grown year after year into a 200-member BJJ club south of Paris: from kids to adults, including fifteen women on the mats. That growth never came at the expense of the club spirit, the sense of belonging Kenji puts at the center of his work.
A competition culture, fully embraced
The number says it all: 60% of BLR members are competitors. The club even counts a French national team member (CFJJB) in its ranks.
That density of competitors demands serious organisation: calendars, registrations, tracking divisions and results. It is exactly the kind of logistics that spirals out of control when it lives in scattered messages and spreadsheets, and exactly what a centralised platform is there to keep under control.

How BLR uses OSS Academy
For Kenji, the app has become the club’s control room:
- Student progress: each student’s journey is visible over time, from first classes to belt promotions
- Merchandising and payments: the club shop and collections run through the platform, with no parallel bookkeeping
- Competitions: deadlines and registrations are centralised for every competitor
- Belt promotions: belts and degrees are recorded and visible to students
- Community: club news lands directly in the pocket of all 200 members
The last word belongs to Kenji: the app helps BLR “foster a sense of belonging and community within our team”. For an associative club whose strength has always been the collective, that is exactly what a tool should do.
