- Quantum-Si Incorporated develops and commercializes advanced protein sequencing technologies through its proprietary single-molecule detection platform. Its core products include the Platinum and Platinum Pro Next-Generation Protein Sequencers™, which enable single-molecule, single-amino-acid resolution sequencing for research use. The company also offers consumables such as library preparation kits, barcoding kits, sequencing kits, and the Platinum Analysis Software, a cloud-based solution that automates data workflows and provides comprehensive visualization for protein analysis. These products support applications in antibody characterization, biomarker identification, protein variant detection, protein barcoding, and post-translational modification analysis. Quantum-Si serves research laboratories and biopharmaceutical companies globally from its headquarters in Branford, Connecticut, and operates within the life sciences and proteomics industry. Recent major developments include the global launch and shipping of the Platinum Pro sequencer in early 2025, featuring enhanced user interfaces, cloud and on-instrument data analysis, and a Pro Mode for custom applications. In 2024, the company introduced new consumables such as the v2 Library Preparation Kit and a new Barcoding Kit, with the v4 Sequencing Kit scheduled for launch in the third quarter of 2025. Quantum-Si is developing a next-generation proteomics platform named Proteus, targeting a mid-2026 launch. Proteus promises ultrasensitive proteoform detection, rapid sequencing chemistry reducing run time to 90 minutes or less, and automated liquid handling to boost sample throughput. The company has expanded strategic collaborations, including a partnership with Planet Innovation for development and manufacturing of the Proteus platform and a collaboration with SkyWater Technology to advance chip production for these platforms. In September 2025, Quantum-Si entered a sales agreement to offer up to $100 million of Class A common stock to strengthen its financial flexibility. Founded in 2013, Quantum-Si integrates biology, chemistry, and artificial intelligence to advance proteomics beyond traditional methods, aiming to revolutionize drug discovery and diagnostics. It operates primarily in the United States, serving the global research and biopharmaceutical communities. Its strategic product evolution and partnerships position Quantum-Si as a pioneer in delivering accessible, high-resolution protein sequencing solutions. This description consolidates Quantum-Si’s core products, recent technological advancements, strategic partnerships, and financial activities through 2024 and 2025.
