About Harbinger Health

Harbinger Health is pioneering the detection of early cancer and enabling foundationally new approaches to cancer screening, diagnosis, and management. Incubated within Flagship Pioneering for three years before launching in 2021, Harbinger combines advances in artificial intelligence with proprietary insights into the biology of early cancer cell formation to identify cancer before it is visible or symptomatic with the aim of developing low-cost, multi-cancer blood tests.

At Harbinger, we intend to lead in shaping this future – creating a proactive paradigm so that people can live cancer-free for longer, adding years to life and life to years. We envision a future where, instead of keeping cancer from spreading, it could be kept from forming, making a cancer diagnosis a routine health problem to be addressed rather than a life-altering event to be feared with profound implications for people, healthcare systems and societies.

Our answer starts with proprietary solutions we are developing with our platform technology.  By making cancer screening accessible on a global scale, Harbinger Health has the potential to fundamentally change cancer care, for everyone.

Our lifesaving work is grounded by our principles of rigor and transparency, constructive engagement, inclusiveness, accountability and quality, and a strong commitment to our customers, patients, and each other.  These values drive our decisions and actions. We are a highly dynamic, entrepreneurial, and innovation-driven organization seeking collaborative, passionate, and dedicated people to join our team.
