Y Combinator 11 months ago 54
BillionToOne, a Y Combinator-backed biotech company founded by computer scientists and engineers, went public after developing a non-invasive prenatal genetic test using machine learning to analyze fetal DNA fragments in maternal blood. The test is now used for roughly 1 in 11 babies born in the US, and the company achieved commercial launch in under two years on seed-stage funding while maintaining consistent revenue growth. The company is expanding into cancer detection via liquid biopsy, with the technology potentially enabling early disease screening at scale.
