About the company
Sunburst Sensors, LLC, a self-certified small disadvantaged business based in Missoula, Montana, manufactures specialized autonomous instruments for marine and freshwater environmental monitoring and sells them to federal agencies as a prime contractor on sole-source purchase orders and small-business set-asides, with minimal subcontract activity. The company is a for-profit limited liability company and goods manufacturer whose federal footprint centers almost entirely on NOAA procurement (77% of awards by count, 87% by potential value).
Sunburst's capability portfolio consists of three core product lines: Submersible Autonomous Moored Instrument (SAMI) sensors in multiple variants (pH, pCO2, alkalinity), the iSAMI handheld sensor family, and ancillary hardware (mooring cages, bio-fouling mitigation packages). Concrete representative work includes a $134 thousand purchase order from NOAA in August 2023 for eight SAMI pH instruments for the Monitoring of Acidification in the Pacific and Continuously Planked Ocean carbon Studies (MAPCO2) program; a $81,321 sole-source purchase from NOAA in February 2023 for four SAMI V.2 pH sensors and four stainless steel mooring cages; a $58,350 NOAA order in September 2024 for three SAMI version 2 pH sensors meeting specific ocean acidification monitoring requirements; a $39,378 total small business set-aside from the U.S. Geological Survey in September 2024 for two pCO2 sensors; and a $30,680 sole-source refurbishment order from NOAA in February 2026 for SAMI Version 2 pH sensor maintenance and repair. The company also holds federal grant funding: a NOAA Phase II project grant running through July 2024 for development of the Phyter, a Bluetooth-connected handheld colorimetric pH meter designed for citizen science and coastal monitoring. Sunburst subcontracts to the University of Montana (software development and prototype design for new SAMI-pHalk instruments under a grant sub-award as of June 2025) and the University of California San Diego (instrument fabrication and deployment support for seaweed farm carbon-capture research as of February 2024).
NOAA dominance is extreme and nearly complete: 51 of 64 prime awards carry $2.6 million in potential value, while the Environmental Protection Agency Office of Research and Development (7 awards, $195 thousand), the U.S. Geological Survey (3 awards, $89 thousand), and the National Science Foundation (2 awards) comprise the remaining customer base. All work is procured as purchase orders under FAR 13.1 authorities, with the vast majority justified as sole-source based on Sunburst's status as the exclusive manufacturer and service provider of the SAMI sensor family. Performance occurs in Missoula, Montana. Award activity has declined from six per year in 2022 to two per year in 2025 and 2026; only one award ($31 thousand) reaches ultimate completion within the next twenty-four months, limiting immediate recompete risk. Sunburst's NAICS profile skews heavily toward Other Measuring and Controlling Device Manufacturing (18 awards) and Analytical Laboratory Instrument Manufacturing (15 awards), consistent with its product-manufacturing posture.
