Playbl is a behavioral digital health company spun out from the play2PREVENT Lab at Yale that harnesses the power of play to help adolescents live happier and healthier lives. Our mission is to market and distribute our 5 evidence-based digital health games that target critical health outcomes in adolescents around mental health, substance misuse, and sexual health. Our games have been developed in partnership with adolescents and tested using the most scientifically rigorous methods. And these are the problems we are solving: Every year, 2M+ adolescents struggle with substance misuse, 5M youth have at least 1 mental health issue, 10M adolescents contract an STI. There is a scarcity of support in schools and clinics (e.g., 1:491 school counselors to students). Averting just 1 opioid use disorder is, over a lifetime, worth $390K to the healthcare sector, $525K to the taxpayer, and close to $3.5M to society. Our games are highly engaging and accessible and can be played on every platform, giving them great potential for scale, reach, and impact on a national and global level.
