Hadley has done a little bit of everything on the path to co-founding Eniac. Starting as a developer and engineering team lead at Pegasystems, he later took on roles as a product manager at Microsoft and strategist at Samsung, where it became clear that big companies were not for him. Hadley is passionate about improving the lives of people with intellectual and developmental disabilities, which stems from his close relationship with his brother Traves. He is a Board Director for Cardinal Cushing Centers, which serves adults and children with intellectual disabilities across 4 campuses in Massachusetts.
