About Quantum-Si
Quantum-Si (NASDAQ: QSI) operates as The Protein Sequencing Company, specializing in single-molecule protein sequencing technology. The company's Platinum benchtop sequencer uses kinetic signatures to detect individual amino acids, enabling detailed analysis of protein variants and post-translational modifications. This semiconductor-based approach combines biology, chemistry, artificial intelligence and microelectronics to deliver proteomic data at the single-molecule level.
The Platinum platform addresses research applications in drug discovery, diagnostics and basic proteomics. By sequencing proteins directly rather than relying solely on genomic inference, the system provides insights into protein structure, function and expression that complement traditional genomic analysis. Quantum-Si's technology targets academic research institutions, pharmaceutical companies and clinical laboratories seeking high-resolution proteomic analysis tools.
The company's interdisciplinary methodology integrates semiconductor chip design with biochemical detection systems. This convergence of technologies allows researchers to study proteins with sensitivity to amino acid-level variations, supporting efforts in precision medicine, biomarker discovery and therapeutic development across multiple disease areas.
