Company description

Quantum-Si Incorporated (including its subsidiaries, “Quantum-Si”, “QSI”, or the “Company”) was incorporated in Delaware on June 10, 2020 as HighCape Capital Acquisition Corp. (“HighCape”). The Company’s legal name became Quantum-Si Incorporated following a business combination on June 10, 2021 between the Company and Q-SI Operations Inc. (formerly Quantum-Si Incorporated) (the “Business Combination”), which was founded in 2013. We are a life sciences company focused on proteomics research, with the mission of transforming single-molecule analysis and democratizing its use by providing researchers and clinicians access to the proteome, the set of proteins expressed within a cell. We have developed a proprietary, universal, single-molecule detection platform that we are applying to proteomics to enable next-gen protein sequencing (“NGPS”) to sequence proteins in a massively parallel fashion (rather than sequentially, one at a time), which can also be used for the study of nucleic acids. We believe in the ability to sequence proteins in a massively parallel fashion and offer a fast analysis time which provides NGPS with the potential to unlock significant biological information through improved resolution and unbiased access to the proteome at a speed and scale not available today. Traditionally, proteomic workflows to sequence proteins required days or weeks to complete. Our current platform includes our Platinum ® NGPS line of instruments, Platinum Analysis Software and consumable kits for use with our Platinum line of instruments.
