What Sigray does
Sigray, Inc. is a privately held scientific instrument manufacturer founded in 2013 and headquartered in Benicia, California, that develops laboratory X-ray systems delivering synchrotron-grade characterization capabilities. The company was co-founded by Dr. Wenbing Yun (formerly founder/CEO of Xradia, sold to Carl Zeiss for $500M+) and Sylvia Lewis, and holds over 60 patents worldwide covering x-ray sources, optics, and imaging architectures. Its product portfolio spans six core systems — QuantumLeap (X-ray Absorption Spectroscopy with sub-eV resolution), AttoMap (microXRF at 3–5µm resolution with sub-ppm sensitivity), Apex Hybrid (combined laminography and CT), EclipseXRM (300nm 3D resolution), TriLambda (40nm nanostructure imaging), and XADA (X-ray Assisted Device Alteration for semiconductor fault isolation) — supported by proprietary components (FAAST and MAAST x-ray sources, double paraboloidal mirror lens optics) and software (GigaRecon reconstruction, XRM Companion acquisition).
The company addresses a primary customer problem: access to synchrotron beamtime is scarce and expensive, yet advanced materials, semiconductor, and life sciences research requires synchrotron-quality microstructural, chemical, and compositional characterization. Sigray's laboratory systems aim to displace synchrotron dependence for routine characterization while maintaining publication-grade data quality. End markets are diversified across semiconductor (failure analysis, advanced packaging, backside power delivery), academic and government research (materials science, batteries, geosciences), pharmaceuticals and food (drug formulation, packaging QC), and life sciences (metallomics, tissue imaging).
Sigray's revenue model is primarily one-time capital equipment sales with multi-year contract cadences, sold through direct enterprise field sales in the U.S. and a global distributor network spanning China, Japan, Korea, Southeast Asia, Australia, Europe, UK, Brazil, Israel, and Canada. Pricing is not publicly disclosed and follows a consultative, quote-based enterprise sales motion via a "Budgetary Quotation Request" web form. Notable enterprise customers and collaborators include Pfizer, NVIDIA (co-published ISTFA 2022 Outstanding Paper), and Challentech International Corporation in Taiwan. The company received CHIPS Act funding in 2024 and prevailed in a jury trial against Carl Zeiss Microscopy GmbH in September 2025. Revenue is not publicly disclosed.
