What Apogee Semiconductor does
Apogee Semiconductor, Inc. is a Plano, Texas-based fabless semiconductor company founded in 2017 to address the commercial-off-the-shelf (COTS) reliability problem for space and defense electronics. The company designs radiation-hardened integrated circuits using a 180nm CMOS (BiCMOS) process at a DMEA Category 1A Trusted foundry, employing proprietary radiation-hardening techniques to deliver immunity to single-event effects (SEE) up to 75-80 MeV-cm²/mg and total ionizing dose (TID) resilience to either 30 krad (LEO variant) or 300 krad Si (GEO variant). Its product portfolio spans eight families: industry-first I/O expanders (APIO16/AFIO16), the ARPS smart high-side power switch family, level translators, fault-containment logic (majority voters, SR latches, arbiters), flip-flops and registers, logic gates (AND/NAND/OR/NOR/XOR/inverter), buffers, and transceivers. Differentiated IP includes Zero-Power-Penalty™ Cold Sparing and the RelBridge™ fault containment architecture that allow mission designers to use affordable COTS parts surrounded by Apogee rad-hard boundaries, replacing fully hardened subsystems at lower cost.
Apogee sells a mix of evaluation-grade, Flight Grade A/B/C (with burn-in options) silicon parts, evaluation boards, and engineering services to spacecraft manufacturers, defense prime contractors, and adjacent high-radiation applications including medical imaging and high-energy physics. Pricing is quote-based, with lead times of 4-8 weeks for evaluation parts and 6-9 weeks for flight-grade parts. The go-to-market is channel-first through five global authorized distributors (Arrow Electronics, Mouser Electronics, Micross, ALTER Technology, Falcon Electronics), supplemented by direct enterprise technical sales for custom solutions, flight-grade qualification, and 24-hour engineering response. Marketing is technical B2B: published datasheets, radiation test reports (TID, SEE), application notes, and presence at space/defense conferences such as SmallSat. Marketing and sales efforts are anchored by ISO 9001:2015 certification (April 2024), DMEA Trusted status, NASA Tipping Point recognition (2019), and the 2025 Military + Aerospace Electronics Technology Innovators Platinum Honoree award.
The company reached a 10,000-unit shipment milestone in 2022, achieved verified flight heritage on March 14, 2023, and has since expanded into GEO/300 krad product families and the power switch category. Cumulative disclosed funding totals approximately $27.25M across grants and rounds through September 2025. Apogee is private, has no parent company or subsidiaries, and is led by CEO David Briggs (former Texas Instruments GM and Active-Semi VP) with a board chaired by Lawrence Blackledge (former CEO of Active-Semi acquired by Qorvo) and including representation from SpaceX, Tyvak, and Terran Orbital veterans.

Apogee Semiconductor competitors and assessment
Company assessmentDirect peers
- CAES (Cobham Advanced Electronic Solutions): CAES supplies space-grade and rad-hard semiconductors — including data converters, memory, and power — to defense and commercial space customers. Apogee's fault containment and power switch portfolio competes for design-wins across overlapping LEO/GEO satellite programs.
- Microchip Technology (Microsemi/Atmel rad-hard line): Microchip is the dominant US rad-hard mixed-signal and logic IC supplier through its Microsemi and legacy Atmel space product lines. Apogee directly competes in rad-hard logic, level translators, and I/O expanders, vying for the same space/defense design slots.
- Vorago Technologies: Vorago Technologies is a fabless rad-hard semiconductor specialist offering HARDSIL-based rad-hard MCUs and analog ICs. Apogee's analog/mixed-signal rad-hard portfolio overlaps Vorago's space-grade MCU and logic offerings for smallsat and defense customers.
- Teledyne e2v (Teledyne Technologies): Teledyne e2v supplies rad-hard and space-grade semiconductors including memory, processors, and analog/mixed-signal ICs to ESA, NASA, and defense primes. Apogee competes for analog/logic sockets in European and US space programs that both companies serve.
- Renesas (Intersil HiRel): Renesas' HiRel division, built on the legacy Intersil space portfolio, offers rad-hard analog, power, and timing ICs for space and defense. Apogee competes most directly in rad-hard logic and level translation where Renesas has long-standing catalog incumbency.
Broad incumbents
- Honeywell Aerospace: Honeywell Aerospace is a long-established supplier of radiation-hardened integrated circuits and sensors for NASA, DoD, and commercial space programs. Its broad portfolio overlaps with Apogee's analog/rad-hard logic offerings as part of a much wider space electronics catalog.
- Analog Devices (HiRel): Analog Devices' HiRel segment supplies rad-hard and rad-tolerant converters, amplifiers, and power management to space and defense. Their broader analog portfolio overlaps with Apogee's power switch and signal conditioning ICs in space satellite electronics.
- STMicroelectronics (Space & Rad-Hard): STMicroelectronics produces radiation-hardened ICs primarily for European space programs (ESA) including rad-hard power and logic. Apogee differs by being US-based and targeting fault-containment around COTS, but they compete for the same satellite rad-hard analog/logic sockets globally.
- BAE Systems (Rad-Hard Microelectronics): BAE Systems produces radiation-hardened microelectronics under its Trusted Foundry programs for space and strategic systems. As a major defense prime contractor it offers Apogee-head-to-head competition for US government satellite and missile programs.
- Texas Instruments HiRel: Texas Instruments' High Reliability product line serves aerospace, defense, and space with rad-tolerant analog, logic, and power management ICs. Apogee's CEO and several senior staff came from TI, and they directly compete for the same analog/logic sockets in satellite designs.
