Our Story

How 399 Det Got Started

It was 2018. Online betting was still largely unfamiliar territory for most people in Bangladesh — foreign platforms had no Bangla support, no local payment options, and customer service in languages nobody could follow. Seeing this glaring gap, a group of entrepreneurs came together around one question: why isn't there a platform built for Bangladeshis, in Bangla, where you can play using bKash?

"We wanted to build a place where a tea vendor in Rajshahi and an IT professional in Dhaka could both play with equal comfort and confidence."

That question sparked the idea behind 399 det. The name might be a little different, but it stands for a simple belief — delivering the best experience at the right price. From day one, we focused on three things: instant deposits via bKash and Nagad, customer support in Bangla, and fair odds. Back then, no platform in Bangladesh was offering all three together.

In our first year, membership stood at around five thousand. Word spread organically — because everyone who tried 399 det told their friends. The Cricket World Cup put the platform to the ultimate test: thousands of bets at once, servers under pressure, payments needing to go out fast. We passed that test and came out stronger for it.

Today, 399 det goes far beyond cricket betting. Football, tennis, kabaddi, eSports, Live Casino, lottery — all under one roof. But what hasn't changed is our core promise: to be honest with you, pay you fast, and stand by you whenever you need us.

399 det is now part of the daily entertainment for millions of people across Bangladesh. That trust is the greatest reward we could ask for — and it's what drives us to keep getting better every single day.
