What Zero-Error Systems does
Zero-Error Systems (ZES) is a Singapore-headquartered semiconductor company founded in 2019 as a spin-off from Nanyang Technological University, specializing in Radiation Hardened by Design (RHBD) integrated circuits that protect commercial-off-the-shelf (COTS) semiconductor devices from radiation-induced failures in space and high-reliability applications. Its core technology addresses Single-Event Latchup (SEL), micro-SEL, and Single-Event Upset (SEU) events, reportedly enabling 10x lower total solution cost than traditional radiation-hardened ICs while permitting the use of advanced COTS chips that are 100-1000x cheaper than space-grade alternatives. The product portfolio spans discrete rad-hard ICs (LDAP ZES100, Smart-LCL ZES744/ZES723, PoL DC/DC ZES302, TMR Voter-IC ZES400), integrated System-on-Modules (ZSOM-F01 FPGA-based and ZSOM-M01 MCU-based), a ZEDAC Voter Module, commercial DC/DC converters, and proprietary RHBD IP library cell licensing, complemented by heavy-ion and laser diagnostic test services.
The company operates a hybrid go-to-market combining direct enterprise field sales with a nine-partner global distribution network covering the USA (Spirit Electronics), Germany (PROTEC), Spain (ALTER TECHNOLOGY), Italy (Dimac Red), Turkey (KEYPART), India (TECNOMIC, MOSCHIP), Japan (CHRONIX), Korea (MID), and Taiwan (ELECBIZ), plus a US subsidiary in Vienna, VA. Revenue streams include semiconductor component sales, non-recurring engineering fees for customized solutions, IP licensing and royalties, and irradiation test services — typically structured as multi-year contracts with quote-based pricing. Primary customers are satellite subsystem manufacturers and integrators, with disclosed implementations at OneWeb, Dhruva Space (three hosted payload missions in pipeline), Kyushu Institute of Technology (three Japanese satellites, 2021), and an unnamed European satellite operator.
ZES has raised approximately US$10 million across seed (S$2.5M, 2020) and Series A (US$7.5M, June 2023) rounds led by Airbus Ventures with participation from Dart Family Office, Delta Electronics, SEEDS Capital, and Silicon Solutions Ventures. The company holds approximately 26 patents in the US and Europe, has grown from 10 to 20+ employees between 2023 and 2024, and is led by CEO Rajan Rajgopal (former Texas Instruments radiation-hardened semiconductor veteran with 25+ years of semiconductor experience) alongside founder/CTO Dr. Shu Wei and founder Professor Joseph Chang of NTU.

Zero-Error Systems competitors and assessment
Company assessmentBroad incumbents
- BAE Systems (Electronic Systems): Supplies radiation-hardened electronics and space-grade components primarily to defense and government space programs. Overlaps with ZES on rad-hard ICs but operates at much larger scale and with defense customer concentration.
- Honeywell Aerospace: Major supplier of rad-hard integrated circuits and space-qualified electronics to government and commercial satellite programs. Competes with ZES in radiation-hardened semiconductor components but as a tier-one incumbent with full ITAR-cleared portfolios.
- Cobham Advanced Electronic Solutions (Transdigm): Supplier of radiation-hardened and space-qualified electronic components and subsystems to aerospace and defense customers. Competes broadly with ZES in space electronics but as a much larger tier-one incumbent.
- Microchip Technology (Microsemi): Long-established supplier of radiation-hardened and radiation-tolerant semiconductors for space applications, with broad portfolios across power management, FPGAs, microcontrollers, and analog. Directly competes with ZES in rad-hard ICs but as part of a much larger product catalog and with deeper qualification heritage.
- STMicroelectronics: Global semiconductor manufacturer offering radiation-tolerant ICs for space applications, particularly in power management and analog domains. Larger, broader catalog competitor with established space qualifications.
- Texas Instruments: Produces rad-hard and rad-tolerant power management ICs, amplifiers, and logic components for space applications. CEO Rajgopal started his career there working on radiation-hardened semiconductors, making it both a peer and a talent feeder for ZES.
Direct peers
- Vorago Technologies: Specialized radiation-hardened semiconductor company focused on arm Cortex-M microcontrollers for space and extreme environments. Closest direct competitor to ZES in offering rad-hard COTS-bridge solutions at smaller scale than tier-one incumbents.
- Ramon Space: Israeli startup developing radiation-hardened processing solutions for space using COTS components. Similar business model to ZES—enabling COTS silicon in space via proprietary rad-hardening—and competes for similar smallsat and constellation customers.
- Space Micro (Voyager Space): Supplier of radiation-hardened space electronics, including processing, communications, and power systems for satellites. Overlaps with ZES in rad-hard components and modules for space applications, with broader portfolio across RF and communications.
