About
BillionToOne is a leading molecular diagnostics company that has commercialized a proprietary technology platform—Quantitative Counting Templates (QCTs)—enabling detection and quantification of disease-related DNA at single base-pair resolution. This breakthrough in cell-free DNA (cfDNA) analysis underpins its two primary product lines: UNITY Screen for comprehensive prenatal genetic screening (covering carrier status, chromosomal conditions, and fetal risk) and Northstar Select for oncology therapy guidance and liquid biopsy.
World's dominant DNA sequencing platform with ~80% market share; ~$4.34B FY2025 revenue. Powers clinical genomics, oncology diagnostics, and population-scale sequencing.
About
Illumina was founded in 1998 in San Diego and has grown into the undisputed leader in next-generation sequencing (NGS), with approximately 80% global market share across research and clinical applications. The company's sequencing-by-synthesis (SBS) chemistry and NovaSeq, NextSeq, and MiSeq instrument platforms have become the standard infrastructure for genomic research, clinical oncology, reproductive health, and infectious disease diagnostics worldwide.\n\nIllumina's business model combines high-margin consumable sales (flow cells, reagent kits) with instrument placements, creating a razor-and-blades recurring revenue structure. Its clinical sequencing segment showed accelerating growth in 2025, with clinical consumables revenue up 20% year-over-year in Q4. The company is expanding into spatial transcriptomics and multi-omics with new instruments unveiled at AGBT 2025, broadening its addressable market.\n\nIllumina reported $4.34 billion in FY2025 revenue and guides to $4.5–$4.6 billion for FY2026, with non-GAAP operating margins of ~23%. Having divested Grail (its liquid biopsy subsidiary) following regulatory pressure, Illumina is refocused on its core sequencing franchise and positioned to benefit from continued clinical adoption of genomic medicine.
