01 - Problem

Tournament and league management was manual, slow, and error-prone

Organizers relied on spreadsheets, WhatsApp groups, and paper brackets, leading to missed registrations, delayed score updates, referee disputes, and poor visibility. Scaling to even 16–32 players became chaotic with no centralized platform.

Players and fans had no real-time leaderboards, social sharing, or quick learning resources. Esports and traditional sports alike lacked a simple, fast tool for event creation, virtual officiating, and multi-admin control.

Problem
01
Manual & Fragmented Operations
Spreadsheets and group chats caused errors in scheduling, registration, and score tracking.
02
No Real-Time Control
Referees couldn’t officiate digitally; no live updates or multi-admin access.
03
Low Engagement
No social sharing, leaderboards, or mini-reads to keep players and fans involved.
02 - Constraints
