Advent Diamond, Inc.

Advent Diamond, Inc., a woman-owned small business based in Tempe, Arizona, manufactures advanced diamond-based materials and quantum sensing technologies for federal defense and research agencies as a prime contractor, competing predominantly under total small-business set-asides on SBIR contracts and full-and-open vehicles on DARPA Other Transaction and DoD IDIQ awards.

Advent Diamond's capability portfolio centers on phosphorus-doped quantum diamond for magnetometry and quantum sensor applications, solar-blind solid-state energetic particle detection for next-generation instruments, windowless alpha and beta radiation detectors, ultraviolet sensing solutions for anti-missile applications, and scaling production of large-area single-crystal diamond substrates for advanced electronics and quantum computing hardware. The company delivers research, prototypes, and finished goods across the Phase I through Phase II SBIR lifecycle and operates under developmental OTA vehicles with DARPA. Representative work includes a $899,999 SBIR Phase II contract from the Shared Services Center (Aug 2025) for phosphorus-doped quantum diamond for magnetometry with completion in 2027, a $1.14 million SBIR Phase II definitive contract from the Shared Services Center (May 2023) for solar-blind solid-state particle detection, and a $1.08 million SBIR Phase II contract from the Defense Threat Reduction Agency (Jan 2022) for windowless alpha and beta detectors. Advent Diamond also holds two DARPA OTA IDVs: a $7.2 million ceiling vehicle (Jul 2024) for ultra-wide bandgap semiconductor research and a $1 million ceiling vehicle (Jun 2023) for large-area device-quality diamond substrates, plus a recently awarded $151 billion Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) IDIQ from the Missile Defense Agency (Dec 2025) with a $500 initial delivery order.

Federal grant work comprises two prime awards: a cooperative agreement from the National Institute of Standards and Technology under the Science, Technology, Business and Education Outreach program (CFDA 11.620, Oct 2022–May 2023) for phosphorus-doped quantum diamond development with Arizona State University and the Larta Institute as sub-recipients, and a project grant from the Department of Energy Office of Science (Jul 2023) for advanced manufacturing of low RON diamond-based power transistors. Customer concentration clusters in defense research and civilian space-agency work: DARPA (2 awards, $8.2 million potential value) anchors the dollar ranking, followed by NASA/Shared Services Center (4 awards, $2.3 million), Defense Threat Reduction Agency (2 awards, $1.2 million), and the Missile Defense Agency (3 awards, $151 thousand). Total awards across nine distinct federal customers stand at 17 (all prime), with combined obligated dollars of $14.3 million against $12.1 million combined potential value. Activity shows a spike in 2022–2023 (four and three awards respectively), with three awards in 2025 anchored by the SHIELD IDIQ award. Three awards totaling $2 million in combined potential value reach ultimate completion within the next twenty-four months and face recompete exposure. The company competes under NAICS 541712 (Research and Development in Physical, Engineering, and Life Sciences) and carries no subcontractor footprint in the source data.
