You might not realize how important certain letters are until they’re gone. A, B and O are the main blood types and when not enough people donate blood, A’s, B’s and O’s may be missing from hospital shelves when a critical patient arrives. Every two seconds, someone in the U.S. needs blood. But for the past four years, new Red Cross blood donors have declined by about 80,000 each year.

Through GroundTruth’s charity program, Location for Good, we’ve been able to support several charities and companies by using our technology to driving awareness and action for good. Now it’s time to support our next cause: American Red Cross’ #MissingType campaign.

GroundTruth and WeatherBug are helping American Red Cross hit a goal of 370,000 new donations this summer. Join us in hitting our company goal of 50 pledges, so patients can receive the lifesaving care they need. Make and keep an appointment today to give blood to the American Red Cross. Simply select the pledge button on the right and enter your zip code to find all blood donation opportunities near you.
