In late 2019, a group of tech enthusiasts and gaming experts asked a simple question: why should people in Bangladesh be denied access to world-class online betting? Several platforms existed at the time, but all of them relied on English interfaces, foreign payment methods, and were never designed with Bangladeshi players in mind. ok big was born to fill that gap.
The team started with just twenty people — a small office, a big dream. Within the first year, ok big won over cricket fans across Bangladesh, and for good reason: bet in Bangla, deposit via Mobile Pay, and get your winnings back fast. Nobody else was offering all three together at the time.
Ok big believes that real trust is the foundation of any business — and trust isn't built overnight. When the whole world came to a standstill during the 2020 lockdowns, ok big's servers never went dark for a single day. By standing by its players through those difficult times, ok big proved that this platform exists not just for business, but for people's enjoyment.
Ok big launched its mobile app in 2021, and user numbers have grown significantly every month since. Players quickly realized that the ok big app isn't just an app — it's an entire casino and betting world that fits right in your pocket.
