Rebet

View Company Profile

Rebet is a free-to-play social sportsbook platform for the U.S. market (available in 47 states) that lets users bet on favorite teams, create peer-to-peer challenges, and share wagers in a social-feed style app. It runs on two currencies: Rebet Coins, a purchasable in-app currency for casual play, and Rebet Cash, earned through promotions and prizes and redeemable after winning wagers. Revenue comes mainly from selling additional Rebet Coins inside the app. The product uses a data partnership with Sportradar to offer betting markets across more than 60 leagues. The social focus and built-in community features set it apart from traditional sportsbooks by enabling friends to compete and socialize around bets. The founders launched the app in 2024 after backing from seven-figure private investment, with the goal of adding a communal, social layer to sports betting and turning social engagement into a revenue stream through digital currencies and promotions.
