What Relyum does

Relyum is the end-equipment product brand of System-On-Chip Engineering, S.L. (SOC-E), a Spanish private limited company (S.L.) founded in 2010 and headquartered in Bilbao, Bizkaia, Spain. SOC-E is part of the Inzu Group. The company specializes in FPGA-based technology for high-availability deterministic networking, sub-microsecond synchronization, and real-time cybersecurity, serving industrial and critical infrastructure operators, defense and military organizations, and aerospace/space programs globally. The company reports that its technology has been applied in more than 200 projects worldwide.

SOC-E operates a two-tier business model. Under the SocTek brand, it licenses proprietary FPGA IP cores (covering TSN, HSR/PRP, PTP, IRIG-B, and SpaceWire protocols) and supplies FPGA-based hardware modules (SMARTix, SMARTzynq, SMARTmpsoc, MEZU-A7G8, Multiport FMC Board) for integration into third-party products. Under the Relyum brand, it sells finished end equipment split into two lines: Relyum Industrial (HSR/PRP/PTP RedBox switches, TSN switches and endpoints, and IEC 61850 testing/validation services for industrial automation and power grids) and Relyum Rugged (deterministic Ethernet switches, high-availability switch routers, secure switch routers, precision time servers, and OEM COTS/M-COTS products for defense applications). Core technical differentiators include sub-microsecond synchronization accuracy, nanosecond-level timing precision, and hardware-based real-time cybersecurity.

The company monetizes through a combination of IP/core licensing, FPGA module sales, and end-equipment product sales, with pricing not publicly disclosed and provided on a quote basis. Go-to-market relies on direct enterprise sales supported by technical content marketing (corporate website, newsletter, LinkedIn, YouTube) and industry-event participation such as CIGRE 2026 in Paris. Customer engagement is driven by a team of Master and PhD engineers and supported by representatives and distributors across geographies.

Direct peers

• Advantech: Advantech is a major industrial networking and embedded computing vendor with managed switches, TSN-capable platforms, and FPGA-ready modules. It directly competes in industrial Ethernet switches and is a comparable scale player to Relyum in factory automation networking.
• Abaco Systems (AMETEK): Abaco Systems, now part of AMETEK, supplies rugged embedded computing, networking, and FPGA-based boards for defense, aerospace, and industrial customers. It overlaps with Relyum Rugged (COTS/M-COTS) and SocTek FPGA modules for mission-critical applications.
• Moxa: Moxa is a Taiwan-headquartered industrial networking specialist selling managed Ethernet switches, TSN switches, and PTP-aware devices for industrial automation. It directly competes with Relyum Industrial in deterministic Ethernet for factories, energy, and rail.
• Kontron: Kontron provides ruggedized embedded computing, networking, and FPGA-based modules for industrial, transportation, and defense applications across Europe. It overlaps with both Relyum Industrial (rugged networking) and the SocTek FPGA module portfolio for OEMs needing integrated platforms.
• Hirschmann (Belden): Hirschmann, a Belden brand, is one of the most established industrial Ethernet switch vendors with TSN-capable products and ruggedized networking for industrial and transportation applications. It competes head-to-head with Relyum in power substations, rail, and factory automation.

Broad incumbents

• Marvell Technology: Marvell produces Ethernet switching silicon and Alaska PHYs that power many industrial and rugged switches, including TSN-capable designs. It is a competitive threat at the silicon layer that SOC-E's IP cores must integrate with, and competes indirectly with the SocTek IP business for TSN switch designs.
• Siemens (SCALANCE): Siemens SCALANCE is the industrial networking line of a global automation incumbent, offering managed switches and TSN support as part of a much broader automation portfolio. Overlaps with Relyum in factory and process automation networking, particularly for Siemens-aligned end customers.
• Cisco Industrial Ethernet: Cisco's Industrial Ethernet (IE) switch family and IOx networking extend its enterprise networking franchise into factory, energy, and transportation deployments. Cisco's scale and IT-OT integration story make it the dominant incumbent that Relyum must differentiate against in TSN-based deployments.
• Microchip Technology: Microchip offers LAN969x and LAN966x Ethernet switches with TSN, along with IEEE 1588 PTP and timing solutions for industrial and defense customers. It is both a potential silicon partner and competitor for SOC-E's switch and timing IP cores.
• Analog Devices: Analog Devices (including former Maxim Integrated) supplies precision timing ICs, IEEE 1588 PTP modules, and clock synchronization silicon used in industrial and defense networking. It overlaps with SOC-E's PTP/IRIG-B timing IP and time server business at the component level.
