BillionToOne is a biotechnology startup that operates in the healthcare sector, specifically in the field of molecular diagnostics. The company's proprietary technology, known as QCT, has the ability to detect and quantify disease at a single base-pair resolution. This means it can identify the tiniest variations in our DNA, which consists of three billion letters or nucleotides.

The company's primary focus is on prenatal screening and oncology testing. Their products, Northstar Select™ and Northstar Response™, are commercially available. Northstar Select™ is used to determine the most suitable first line therapy for patients, while Northstar Response™ monitors the effectiveness of the therapy.

BillionToOne's business model revolves around providing these diagnostic services to healthcare providers. They generate revenue by selling their testing services to these providers, who then use the results to guide their treatment plans.
