Sep 2023Series BFlagship Pioneering (lead); Catalyst; Pictet Private Equity Investors S.A.; M&G Investments; Partners Investment; Modi Ventures$140MHarbinger Health is a biotechnology company developing a proprietary two-tier, multi-cancer early detection platform using blood-based liquid biopsy tests combined with AI and machine learning to identify cancer at its earliest stages before symptoms appear. Founded by Flagship Pioneering after three years of research in its Labs unit, the company launched in 2020 with an initial $50 million commitment from Flagship and has since raised approximately $190 million in total funding. On September 28, 2023, Harbinger Health announced a $140 million Series B financing round led by founder Flagship Pioneering, with participation from new global institutional investors including Pictet Private Equity Investors S.A., Partners Investment, Catalyst (M&G Investments’ purpose-led private assets strategy), and Modi Ventures. The funding will accelerate advancement of Harbinger's screening platform, including completion of the ongoing CORE-HH clinical study (10,000+ participants, primary completion December 2023), initiation of additional trials in high-risk populations, expansion of data science and commercial teams, and global scaling of its patented two-tier testing model for performance, accessibility, and cost optimization. The company envisions shifting cancer management from treatment of advanced disease to prevention and early intervention. Harbinger has achieved clinical milestones such as data presentations on platform performance and key executive hires. It plans to launch a laboratory-developed test in 2025.
Dec 2021Series AFlagship Pioneering (lead)$50MHarbinger Health is a bioplatform company pioneering early cancer detection through a simple blood test that integrates artificial intelligence, machine learning, and insights into early cancer biology. Founded in Flagship Labs in 2018 and launched from stealth on December 7, 2021, the company develops the proprietary HarbingerHx platform for liquid biopsy tests and software to identify cancer before it becomes visible or symptomatic, enabling early interventions. Flagship Pioneering provided an initial commitment of $50 million to Harbinger Health upon its public launch, marking the specified funding round led solely by Flagship. Stephen Hahn, M.D., former FDA Commissioner and Chief Medical Executive of MD Anderson Cancer Center, was appointed CEO at launch and became a Flagship CEO-Partner. The funding supports development of blood-based multi-cancer screening tests, including studies with high-risk populations, data science expansion, and commercial team buildout. Harbinger aims to make cancer screening routine, affordable, and accessible, potentially transforming oncology from late-stage treatment to preemptive detection. By a later Series B in approximately 2024, Harbinger raised $140 million from Flagship Pioneering and new investors including Pictet, Partners Investment, and M&G Investments’ Catalyst fund, bringing total funding close to $200 million. The company continues advancing its platform, with ongoing validation studies involving 10,000 participants and plans for disease-specific tests. In August 2025, Ajit Singh, Ph.D., a diagnostics veteran from Siemens, was appointed CEO, succeeding Hahn who transitioned to CEO Emeritus; Singh had been a board member since 2024.
