Personalized health, made possible for everyone — starting with cancer.
Most people don't learn they were at risk until it's already late. We started Stage Zero, as a public benefit company, to change the part of that story a benefits program can actually rewrite: who gets found early.
Cancer prevention should be clear, personal, and within reach.
Stage Zero Health is a public benefit company. Early detection shouldn't depend on how well you can navigate a complex healthcare system — but today it does. The science of who is at risk, and what to screen for, already exists; it just rarely reaches the people who need it, at the moment it would matter.
We bring that science to the whole population. We use validated clinical risk models to find who is most likely to benefit from screening, then put a real person alongside them to make the right screening actually happen — through their own health plan and their own doctors. We measure ourselves by one number: the people we help keep healthy.
The people behind the science.

Building in the open, one cancer pathway at a time.
2024 — Founded
Stage Zero Health launches in Cambridge, MA as a public benefit company, with a simple premise: bring validated cancer-risk science to the people it rarely reaches.
2025 — First build & pilot
After interviewing hundreds of people, we built our first product focused on breast and ovarian cancer risk — the models with the strongest validation and the clearest screening pathways.
2026 — Expanding
We're extending our models toward the broader set of guideline-recommended screenings — including the breast and cervical navigation employers are now required to cover — integrating genetics, and bringing the program to employers and benefits consultants as a screening-navigation layer.
Build the upstream layer with us.
Whether you run benefits, advise employers, or just want to know your own risk — there's a door here for you.
