Built by people who’ve sat in your chair.
Doctors use AI on millions of cases a month. Now patients do too. OpenCancer puts the same intelligence to work, only for you, with real cancer scientists behind it.

Ari Akerstein · Co-founder & CEO
In 2018, as a new dad, Ari was diagnosed with an aggressive blood cancer.
A product leader (ex-Meta, Included Health, Walmart Labs) with graduate training in molecular biology, he PM’d his own treatment and wrote about it in Chemolog. Most patients don’t have that time or that training. OpenCancer is the toolkit he wishes he had: records translated to plain English, trials you’d otherwise miss, and the right questions for your next appointment.

Brad Power · Co-founder
Brad spent a career redesigning how work gets done. Then cancer arrived.
With 100+ articles published with Harvard Business Review, Brad turned that discipline on the disease: he co-founded the Cancer Patient Lab, helping patients use cutting-edge diagnostics and evidence to go beyond standard of care. He has been profiled by Cancer Commons and the National Coalition for Cancer Survivorship.
Why “open”? Patients deserve access to the personalized tools and trusted services that too often get missed in healthcare.
