About Quantum Si Incorporated

Quantum Si Incorporated's Quantum-Si Incorporated Division manufactures advanced protein sequencing instruments and reagents for the Department of the Navy as a small disadvantaged business prime contractor, competing on sole-source and competitive full-and-open purchase orders with no set-aside designation. Headquartered in Branford, Connecticut, Quantum Si is a for-profit manufacturer focused on next-generation protein analysis technologies, with all four recent federal awards (100% prime, zero subcontract footprint) directed to Navy customers between September 2024 and November 2025.

The vendor's customer base is heavily concentrated within the Department of the Navy. The Office of Naval Research accounts for three awards totaling $293 thousand in combined potential value, while the Bureau of Medicine and Surgery holds one award valued at $29 thousand — collectively representing the vendor's entire federal footprint across the capture window. The two Navy offices rank identically in both award count and potential value, indicating no material divergence between volume and dollar concentration.

Quantum Si's recent work spans protein sequencing consumables and instrumentation. A $170.5 thousand firm fixed-price purchase order from ONR (September 2024) covered OUSD-funded bioprototyping services. A $63,112.50 ONR purchase order (February 2025) procured sequencing reagents and chips for four Platinum-system runs. A $29 thousand Bureau of Medicine and Surgery purchase order (May 2025) delivered a Platinum Pro Instrument with twelve months of warranty, analysis software, and cloud data storage. A $59,220 ONR purchase order (November 2025) covered reagent preparation and sequencing kits under sole-source authority, citing Naval Research Laboratory's determination that only one responsible source could satisfy requirements. All awards carry firm fixed prices and short performance cycles (six to twelve weeks), executed under Simplified Acquisition Procedures.

Combined potential value across all awards stands at $322 thousand, with 100% obligated. Activity has grown modestly — one award in 2024 to three in 2025. The vendor operates as a pure prime on Navy lab and biotech procurement, with no parent vehicle positions, GSA Schedule seats, or subcontract relationships in the source data.
