Will Yin

Will Yin is the co-founder and CEO of Mandolin, a San Francisco AI automation company building autonomous agents for specialty drug access. A Greenwich High School valedictorian and Stanford dropout, Yin previously co-founded Jupiter (YC-backed, $9M raised) before pivoting to healthcare. At Mandolin, he and co-founder Rohit Rustagi have raised $97M to automate the back-office workflows — prior auth, benefits verification, billing — that delay cancer and Alzheimer's patients from getting life-saving specialty therapies. Within months of launch, Mandolin deployed across 700+ clinics serving 250,000+ new patients annually.
