About Sienna Technologies, Inc.
Sienna Technologies, Inc., a Mukilteo, Washington–based for-profit Subchapter S corporation and specialized manufacturer of high-performance sensors and electronic components, operates as a prime contractor (98% of recent awards) delivering custom sensor packaging, fabrication, and materials solutions to NASA and Department of Defense customers under sole-source purchase orders with no set-aside designations. The company has held federal contractor status since 2002 and competes in full-and-open procurements, not set-aside categories.
Sienna's capability portfolio centers on silicon carbide and aluminum nitride sensor packaging, advanced materials fabrication, and integrated circuit assembly for extreme-environment aerospace and defense applications. Representative recent work includes a $136,040 firm fixed-price purchase order from NASA's Shared Services Center (awarded February 27, 2026) for silicon nitride materials supporting high-temperature sensor packaging; a $143,750 purchase order from NASA SSC (June 11, 2024) for DRPA sensor chip packaging rated to 900 degrees Celsius and 500 psi; a $123,000 contract from NASA SSC (March 8, 2022) for on-chip integrated silicon carbide pressure and micro-thermocouple sensor packaging; and a $53,228 purchase order from Naval Sea Systems Command (January 30, 2026) for attenuators. Each of these awards was conducted under FAR 13.106-1(b)(1)(i) sole-source authority, reflecting Sienna's position as the sole qualified provider for specialized sensor and packaging capabilities.
Customer concentration is concentrated within NASA and defense technical commands. The top five customer entities account for 64% of awards by count and 72% of combined potential value, anchored by NASA's Shared Services Center (18 awards, $2.3 million combined potential value) and NASA Glenn Research Center (17 awards, $794 thousand). The Department of the Air Force Materiel Command Research Laboratory ranks second by potential value at $1.2 million across five awards, followed by the Department of Defense Missile Defense Agency at $1.1 million, Department of the Navy, and NASA's Jet Propulsion Laboratory. Top NAICS categories reflect Sienna's R&D and manufacturing footprint: Research and Development in the Physical, Engineering, and Life Sciences (20 awards), Engineering Services (11 awards), and Other Electronic Component Manufacturing (10 awards).
Sienna's activity profile shows sparse but consistent recent awards. The company received two awards in 2026 year-to-date, five in 2024, and one each in 2021 and 2022, with a combined potential value of $8.4 million across 89 total awards since 1997. Obligated dollars ($16.7 million) exceed potential value by 98 percent, indicating substantial completion or re-obligations. In its subcontractor role, Sienna supplies aluminum nitride absorbers to Verus Research for a Space-compatible Anechoic Technologies Retrofit program and delivers radar panel components to Leidos under the MJOLNIR contract. Sienna maintains no presence on government-wide vehicles or BPAs; its federal revenue flows through individual purchase orders and task-order relationships managed by NASA and Department of Defense contracting offices at Mukilteo and Woodinville, Washington.
