The Opportunity

Problem

Gaming startups in Djibouti cannot reliably host online multiplayer games or esports events due to inconsistent high-speed internet.

Solution

DuelSync enables turn-based multiplayer esports with offline recording and cloud sync, perfect for inconsistent connections. Players record local matches, upload when stable, and leaderboards update automatically. Gaming startups host events without live streaming risks.
