Koko has reached over 5,000,000 young people and over 91% of users have found our services helpful. Our goal is to expand further, envisioning a world where services like ours are accessible to everyone for free, with zero friction and complete ubiquity.

"A lot of people express online that they are struggling, and we don’t yet have a good understanding of how best to provide help and support. Koko is filling this gap and providing scientifically-supported tools to help those who are struggling. They’re figuring out what works best and then putting it to work to help people." - Dr. Matthew Nock, Ph.D.
