Quantum SI

Historical price data

Quantum-Si's mission is to make single-molecule protein sequencing accessible to every lab, thereby unlocking the proteome. The company has achieved this by commercializing the Platinum Pro, the world's first benchtop next-generation protein sequencing (NGPS) instrument, which uses kinetic signatures for real-time, single-amino-acid resolution. Its strategy leverages a platform model, selling instruments and consumables, while exploring high-value applications in ultrasensitive protein detection (USPD) for diagnostics through partnerships. Quantum-Si aims to become the foundational technology for the burgeoning field of proteomics.

Quantum-Si's platform integrates semiconductor technology, single-molecule fluorescence, and kinetic analysis to enable next-generation protein sequencing (NGPS) and ultrasensitive protein detection (USPD) on a benchtop instrument.

Quantum-Si competes directly with mass spectrometry giants (Thermo Fisher, Bruker) in research proteomics, with ultra-sensitive immunoassay leaders (Quanterix) in diagnostics, and with a cohort of well-funded private companies (e.g., Nautilus Biotechnology) developing alternative protein analysis platforms. Its differentiation hinges on single-molecule kinetic sequencing and benchtop accessibility.
