Our take

BillionToOne is a precision diagnostics company. Its proprietary molecular counting platform (Quantitative Counting Templates) accurately counts DNA molecules at the single-count level, which has the ability to significantly improve disease detection. While initially focused on prenatal screening and oncological liquid biopsies, the company’s QTC technology is highly scalable and has the ability to make vast improvements to a range of disease detection verticals.

The company’s funding efforts - most notably a 2025 IPO - will enable it to focus on further development and commercialisation of its noninvasive prenatal screening test and oncology products. However, it will need to maintain a strategic outlook, prioritising areas with higher testing frequencies to maximise patient benefit and balance test development costs.

BillionToOne has an important role to play in improving healthcare equity. As more promising peer-reviewed research studies are conducted and providers have increased confidence in the company’s tests, BillionToOne has significant growth potential.
