4YouandMe was formed in 2017 to help lower the burden of chronic diseases, especially for those who ha

ve the highest need and lowest access to quality care.

We are a non-profit organization comprised of an international coalition of partners including researchers, clinicians, software engineers and mathematicians.

Our 4youandMe core team includes:

Co-Founder and President

Dr Stephen Friend

Professor of connected medicine at the University of Oxford, and Chairman and co-founder of Sage Bionetworks.

Dr. Friend is an authority in the fields of genetic resilience, cancer biology, and digital health. At Dana Farber and MIT his team cloned the first human cancer susceptibility gene. While on the Faculty at Harvard, he was jointly recruited with Lee Hartwell to co-found "The Seattle Project” at the Hutch and then co-founded and led Rosetta Impharmatics were they developed the RNA expression approaches to assess the aggressiveness of breast cancers. Merck acquired Rosetta and as SVP for Oncology he rebuilt the cancer franchise using molecular profiling techniques, which would later show value in assessing the sensitivity of tumors to Keytruda.

After working at Apple from 2014-2017 on digital health, he is now a co-founder and President of 4YouandMe, the Founder and Chairman of Sage Bionetworks, and based Oxford as a Visiting Professor of Connected Medicine. Stephen is both an Ashoka fellow and a AAAS Fellow.
