What RADX Technologies, Inc. does

RADX Technologies, Inc. is a privately held, US-domiciled designer and assembler of COTS (Commercial Off-The-Shelf) PXIe modules for the modular Test and Measurement market. Founded in 2011 and headquartered in San Jose, California, with engineering in California and Utah and a Palo Alto mailing address, the company operates with 1-10 employees and is led by CEO Ross Smith. RADX's portfolio comprises four product families — PXIe-SSD storage (Venturi, Trifecta RAID, Trifecta Removable), PXIe-GPU compute (Catalyst, Trifecta, Orca-C2X built on NVIDIA professional GPUs across Ampere, Ada, and Blackwell RTX Pro architectures), PXIe-GbE networking (10/25/100 GbE NICs based on NVIDIA Mellanox ConnectX-6 and Intel XL710), and PXIe-USB-C connectivity — all designed as single-slot modules that bring data center-class compute and storage directly into PXIe chassis from NI, Keysight, and Pickering.

RADX serves defense, aerospace, electronic warfare, SIGINT, semiconductor test, and modular T&M system integrator customers, with all products BAA/TAA compliant, designed and assembled in the USA, and listed on GSA Advantage via GSAMart/TestMart. Its go-to-market combines direct sales, a VAR/systems integrator channel, the NI Application Solution & Product Partner relationship, regional distribution via KT-UK (UK/Europe), and an event-led presence at NI Connect and AOC. Revenue is generated entirely through one-time/perpetual hardware license sales priced from $1,999 to $9,999 per unit, with no disclosed subscription or recurring component. The company holds patent-pending technology in its Venturi PXIe-SSD and Catalyst-X carrier card designs, holds no disclosed external funding, and has continuously launched new products since 2019 — most recently Catalyst-X Blackwell-based GPU modules at NI Connect 2026.

Broad incumbents

• Mercury Systems: Mercury Systems designs mission-critical defense electronics, including embedded computing and signal processing modules for EW, SIGINT, and radar — competing with RADX for DoD prime contractor spend on high-performance COTS compute.
• Keysight Technologies: Keysight is a global leader in electronic test and measurement instrumentation, including a broad portfolio of PXIe modular instruments. RADX's Catalyst and Trifecta modules are explicitly compatible with Keysight PXIe chassis, positioning Keysight as both a competitor and ecosystem enabler.
• Curtiss-Wright Defense Solutions: Curtiss-Wright supplies ruggedized COTS embedded computing, networking, and signal processing modules for defense and aerospace. While broader than PXIe, it competes for the same defense EW/SIGINT T&M slot budgets and integrates similar NVIDIA/Intel silicon.
• National Instruments (NI / Emerson): NI owns the PXI/PXIe platform standard that RADX's modules are designed around. RADX is an NI Application Solution & Product Partner, complementing NI's own chassis and controllers with third-party GPU/SSD/GbE/USB modules. NI/Emerson is the dominant incumbent in the same ecosystem.

Direct peers

• ADLINK Technology: ADLINK produces a broad portfolio of PXI/PXIe-based data acquisition, computing, and GPU modules for test, measurement, and embedded computing applications — directly overlapping RADX's Catalyst and Trifecta product lines in modular T&M compute.
• Pickering Interfaces: Pickering manufactures PXI and PXIe switching, simulation, and instrumentation modules targeted at the same defense, aerospace, and T&M customers. RADX modules are explicitly compatible with Pickering chassis, and the companies compete for adjacent PXIe slot budgets.
• Kontron: Kontron manufactures embedded computing modules (COM Express, SBCs) and PXI/PXIe-class modules for industrial and defense applications, overlapping with RADX's embedded compute positioning in COTS modular systems.
• VX Instruments: VX Instruments produces PXI/PXIe modular test and measurement instruments with overlapping defense and aerospace T&M customer base. A direct competitor in the PXIe module ecosystem.
