Client

A US-based sports gaming startup delivering multi-sport social fantasy and betting experiences across Web, Android, and iOS platforms. The client engaged Systango to engineer a custom, multi-sport social fantasy gaming product tailored to their proprietary business model and reward system.

Challenge

  • Multi-sport consolidation gaps: Existing fantasy gaming solutions could not support simultaneous investments and play across multiple sports options within a single interface.

  • Real-time scoring & leaderboards: Calculating live fantasy scores, updating dynamic leaderboard rankings, and maintaining wallet synchronization under high concurrency.

  • Cross-platform feature parity: Building and testing complex user flows seamlessly across Web, Android, and iOS environments.

  • Secure financial workflows: Designing reliable wallet management, token purchase mechanisms, referral reward tracking, and cashout functionality.
