We build software (LMS) for coaching centers in Bangladesh

Biddaan is a learning management system (LMS) built for coaching centers in Bangladesh. Attendance, online exams, fee collection and a student portal in one place, in Bangla. Biddaan is built and run by NerdDevs Ltd., a software company in Dhaka.

Our story

Where WhatsApp and Excel stop working

Most coaching centers in Bangladesh still run on WhatsApp groups, paper registers and Excel. Once a center passes 300 students, the day goes into matching attendance, chasing unpaid fees and putting together exam results.

Biddaan launched in 2025 to solve that. Attendance, exams, fees and a student portal in one place, in Bangla, set up in 48 hours.

Today 29,800+ students at 165+ coaching centers use Biddaan. From small neighbourhood coaching centers to large institutions like Fahad's Tutorial, they all run on the same platform.
