SocialBlood’s Story

Socialblood is a social network that connects blood donors and recipients of the same blood type through Facebook. Socialblood, has created a social space for thousands of potential blood donors and recipients to meet and potentially donate.

Karthik Naralasetty is an internet entrepreneur and founder of social networking site socialblood. He was born in Andhra Pradesh, India. Karthik dropped out of Rutgers University, New Jersey in 2009 to found his own technology company called redcode Informatics in Bangalore, India.

Karthik Naralasetty saw a request on Facebook seeking a B+ blood donor for his father who was undergoing a heart surgery. Surprisingly, after two hours a new post read, “Thanks to Facebook, we found a donor for my dad!” That got Karthik thinking that Facebook can be used to solve the issue of finding blood donors when in emergency. Not long after his return, Karthik witnessed near his home in Bangalore a family’s struggle to find regular blood transfusions for their four-year-old daughter to treat her thalassemia, a genetic blood disease. Every 25 days the family experienced the nightmare of trying to secure blood, going from hospital to blood bank, regularly being informed that they would be sold blood only if they provided a donor to replenish the supply. Studies have shown that a main reason people do not donate blood is because “no one asked them.” In a country of billion people, Karthik realized he could make a difference by finding those would-be donors who had never been asked. He created, a social media platform that connects blood donors and recipients of the same blood type through Facebook.

The idea is simple—so simple, in fact, that it is a bit too limited right now. The Socialblood website links to eight different groups on Facebook, one for each blood type. You can request to join the Facebook group for your own blood type and a moderator will approve your request. For instance people having blood type A+ will be in one group while B+ in another and so forth, they are doing this so that in case of an emergency people can quickly reach out to the blood group of their need.

In November 2011 Karthik won the Staples Youth Social Entrepreneur Award for his work at
