The challenge
When someone needs blood, families scroll through Facebook groups and call numbers that are years out of date. Donors who gave blood last month get calls they cannot answer, and fake donors waste precious time.
Our approach
- 01
Only donors who can give today
Search shows only approved donors who are ready and last gave blood at least 90 days ago. SMS-verified donors are listed first, and visitors can report fraud donors.
- 02
Alerts that reach the right people
A new blood request alerts subscribers within 50 km by push notification, capped so nobody is spammed. Donors also get a reminder on the day they can give again.
- 03
Bangla first, fast on any phone
Fully Bangla and installable as an app that works offline, with shareable request posters, donor photocards and an AI assistant that answers questions in Bangla.
