Cloudsci LLC

Cloudsci LLC, a Fort Collins, Colorado-based small business, develops advanced aerosol measurement and sensing instrumentation for federal research agencies exclusively under total small business set-asides as a prime contractor. The company operates entirely in the SBIR and STTR research funding space, with no subcontract footprint and no parent vehicle participation — all ten recent awards are direct prime awards split between research contracts and federal grants.

Cloudsci's customer base concentrates heavily on three federal agencies. NASA's Shared Services Center accounts for five awards worth $2.3 million combined potential value, anchoring the largest share of the portfolio. The Department of the Army's Materiel Command Research Development and Engineering Command placed two awards ($1.5 million combined potential value), and the Department of Energy's Office of Science awarded three grants. The two rankings align closely — NASA leads both volume and dollars, followed by Army, then DOE. Across all ten awards, the vendor has obligated $6.2 million against a combined potential value of $3.8 million, indicating substantial contract performance acceleration or option exercise activity beyond initial ceiling estimates.

Cloudsci's capability portfolio centers on sensor development and instrumentation for in situ aerosol characterization. Representative work includes a $1.318851 million Army SBIR Phase II contract (April 2026, ultimate completion April 2028) for development of a portable instrument prototype for morphological classification of biological and nonbiological aerosol particles; a $899,843 NASA Phase II SBIR definitive contract (July 2024, ultimate completion May 2027) for an airborne multiangle aerosol size spectrometer; and a $256,500 Department of Energy Office of Science grant (February 2025, ultimate completion February 2026) for a Single Aerosol Particle Spectrometer for in situ measurement of chemical composition under CFDA 81.049. Earlier Phase I work includes an $844,528 NASA Phase II SBIR contract (July 2025, ultimate completion July 2027) for an airborne holographic probe for small ice detection and a $148,812 NASA Phase I SBIR contract (August 2024, ultimate completion February 2025) for the same airborne holographic probe concept. DOE grant work also includes a low-cost networkable fluorescence spectrometer for pollen identification and a low-cost holographic sensor for urban aerosol characterization running through March 2027.

Activity has remained flat at two to three awards annually since 2023, with five awards (combined potential value $3.3 million) reaching ultimate completion within the next twenty-four months and therefore facing recompete pressure. All work is performed in Fort Collins, Colorado. The vendor's category concentration sits in Research and Development in the Physical, Engineering, and Life Sciences (six awards) and General Science and Technology R&D Services across both basic research and administrative support roles.
