BilliontoOne, a company specializing in molecular diagnostics, has closed a new C-2 financing round of $48.5 million. This significant investment was led by the company’s existing investors. The funding will be used primarily to expand its oncology and prenatal testing solutions.
BilliontoOne Investment to Expand Oncology and Prenatal Testing
The company plans to use the proceeds in two main areas. First, it will scale its oncology portfolio, including Northstar and new liquid biopsy products. Second, it will expand the reach of its pioneering prenatal screening test, UNITY Screen.

Existing backers are among those leading this round. Major investors such as Hummingbird Ventures and Four Rivers Group have reaffirmed their belief in BilliontoOne’s vision, demonstrating their confidence in the company’s technology.
BilliontoOne owes its success to its proprietary molecular counting technology, Quantitative Counting Patterns (QCTs). This technology provides high sensitivity for both early cancer detection and prenatal screening. Furthermore, the company’s liquid biopsy tests aim to provide patients with better treatment options.
