100 Thieves and Be The Match Mobile 1

Save lives
with 100 Thieves

100 Thieves and Be The Match are teaming up to save lives. Gamers including NoahJ456 and Neeko are on a mission to add 10,000 potential new blood stem cell donors to the Be The Match Registry®.

70% of blood cancer and blood disease patients do not have a fully matched donor in their family. They depend on people like you to literally be their cure.

Are you Michaela's match?

100 Thieves Michaela

Michaela is 23 years old. She loves dogs, watching movies and playing Call of Duty. Michaela is also battling blood cancer for the third time.

The only cure is a blood stem cell donation from an unrelated donor–but right now, Michaela doesn’t have a match on the donor registry.

You could match Michaela or one of the thousands of patients who need help. Your healthy blood stem cells could change someone’s world.

About Be The Match®

For people with life-threatening blood cancers—like leukemia and lymphoma—or other diseases, a cure exists. Be The Match connects patients with their donor match for a life-saving marrow or umbilical cord blood transplant. People can contribute to the cure as a member of the Be The Match Registry®, financial contributor or volunteer. Be The Match provides patients and their families one-on-one support, education, and guidance before, during and after transplant. ​ Be The Match is operated by the National Marrow Donor Program® (NMDP), a nonprofit organization that matches patients with donors, educates health care professionals and conducts research through its research program, CIBMTR® (Center for International Blood and Marrow Transplant Research®), so more lives can be saved.
