The Vision: Democratizing Maternal Healthcare

Shohay (meaning “helpful” or “supportive” in Bengali) was conceived to address a critical gap in Bangladesh’s maternal health landscape. Despite significant improvements in healthcare infrastructure, expecting parents-particularly in semi-urban and rural areas-lacked access to:

• Medically verified pregnancy information in their native language
• Structured guidance aligned with Bangladeshi healthcare protocols
• Digital tools to manage medical records and appointments
• Support systems that engaged both mothers and fathers

Dr. Tasnim Jara envisioned a platform that would serve as a digital midwife-combining evidence-based medical content with the cultural sensitivity required for Bangladeshi families.

To realize this vision at scale, Shohay Technologies partnered with Appinion BD Limited, a software development company with deep expertise in high-scale mobile applications and offline-first architecture for the Bangladeshi market.
