BloodLink
Find a blood donor nearby, fast, with contact details shared only when the donor says yes.
BloodLink, shown to users as BloodDonor.site, connects people who need blood with willing donors nearby. Donors sign up with their blood type and location. Hospitals and patients search compatible donors and send a request; contact details are shared only when the donor accepts. Hospitals get 100 free searches and then a subscription; sponsors fund the service and are thanked in the app.

The problem
- In many countries families must find blood donors themselves, often through social media posts in an emergency.
- Donor lists are on paper or in chat groups and quickly go out of date.
- Donors are afraid of their phone number being spread publicly.
The product
A donor registry with privacy built in. Searches show compatible donors by blood type and distance, without contact details. A request goes to the donor, who accepts or declines. Only on acceptance are phone and email shared both ways. Private receivers can search for free within daily limits; hospitals must be verified.
- Donors sign up with blood type and location.
- A hospital or patient searches for compatible donors nearby.
- They send a request to selected donors.
- The donor accepts; contact details are shared both ways.
- Sponsors are shown and thanked, which funds the service.
Who pays and why
Business model
| Revenue line | Price | Notes |
|---|---|---|
| Hospital plan | $300 / month | After 100 free searches including contact. |
| Sponsor tiers | Main, partner, supporter | Logo in app, emails and reports, with their own portal. |
| Private receivers | Free | Daily limits prevent abuse. |
Sponsors get a portal with views, clicks and real donor impact, and a printable report.
Market and targets
The need is greatest where blood supply depends on family replacement donors, which is common in many developing countries. There, an organised, privacy-safe registry is valuable to hospitals and attractive to sponsors who want visible local impact.
Targets are planning assumptions.
