About Koaryu
Serious studio software for schools that still feel personal.
Koaryu exists for martial arts owners who need a calmer way to run students, ranks, attendance, trials, billing, and retention without inheriting enterprise software complexity.
Positioning
Koaryu is intentionally narrower than generic gym software.
The product is built around the rhythm of a martial arts school: the student who misses class, the trial family waiting for a call, the instructor reviewing promotions, and the owner who needs to know whether the school is healthy before the evening rush.
Built for independent schools
Koaryu is focused on owner-operated and small-team martial arts studios, not enterprise gym chains.
Studio data should stay understandable
Student, guardian, attendance, rank, lead, and supported billing records stay visible and scoped to the school; new billing exports are currently unavailable.
Daily action beats dashboard theater
The product should answer what needs attention today: follow-ups, classes, promotions, retention, and tuition issues.
Koaryu
Reliable daily operations for one independent studio.
Koaryu supports one studio per user with explicit Admin, Front Desk, and Instructor boundaries. It centers the roster, ranks, schedule, attendance, leads, and honest visibility into existing billing records. Provider-backed billing changes and live Stripe activation are currently unavailable.
