About BillionToOne BillionToOne
is a next-generation molecular diagnostics company on a mission to make powerful, accurate diagnostic tests accessible to everyone. Our revolutionary QCT molecular counting technology enhances disease detection resolution by over a thousandfold using cell-free DNA—a breakthrough that’s transforming lives worldwide.
Our Impact:
We’ve pioneered diagnostic solutions redefining industry standards. Unity Complete assesses fetal risk for both common recessive conditions and aneuploidies from a single maternal blood sample. In oncology, our Northstar liquid biopsy test combines treatment selection with real-time monitoring for precision cancer care.
Our Growth:
From $0 to $125 million in Annual Recurring Revenue in four years. We’ve raised close to $400 million in funding, including a $130 million Series D in June 2024, with a valuation over $1 billion. Investors include Hummingbird, Adams Street Partners, Neuberger Berman, Baillie Gifford, and Premji Invest.
Our Recognition:
Forbes named us one of America’s Best Startup Employers for 2025, and we hold Great Place to Work certification (2024). Our team reports high engagement and commitment to getting the job done.
Our Future:
Headquartered in Menlo Park with facilities in Union City, California, we continue to push the boundaries of molecular diagnostics. Recent clinical outcomes data and new cancer diagnostics advances show we’re just getting started.
