What Ac6 does

Ac6 SARL is a privately held French company headquartered at 19 rue Pierre Curie, 92400 Courbevoie, in the Paris region, with a copyright notice running from 2004 through 2026. Operating across three wholly owned subsidiaries, Ac6 delivers a complete services stack for embedded electronic systems: ac6-training offers professional training courses covering industrial computing, embedded systems, and real-time programming; ac6-conseil provides engineering, consulting, and embedded-systems expertise; and ac6-tools (and a separate Workbench for Zephyr brand at z-workbench.com) supplies development tools such as the System Workbench for Linux IDE, which supports asymmetric multicore debugging across Cortex-A (Linux) and Cortex-M (bare-metal/FreeRTOS) cores on platforms including STMicroelectronics STM32MP1 and NXP i.MX8mq.

The training catalogue is Ac6's primary commercial surface, delivered both as scheduled online instructor-led sessions (across US Pacific, European CET, and Asia-Pacific time zones) and as onsite courses at customer premises. Curriculum depth spans Zephyr RTOS, FreeRTOS, embedded Linux using Yocto, STM32 microcontroller development, LwIP TCP/IP on STM32, secure C/C++ development covering ISO/SAE 21434 and IEC 62443, and a recently added EU Cyber Resilience Act compliance course. Ac6 also publishes technical white papers on asymmetric multi-programming, embedded Linux platform creation, and securing embedded Linux, which function as demand-generation for the consulting and tools businesses.

The revenue model is a blend of three professional-services and licensing streams: per-session training fees (online and onsite), engineering consulting engagements booked through ac6-conseil, and one-time licenses for System Workbench for Linux and Workbench for Zephyr. Pricing is not publicly disclosed. Ac6 maintains Core-tier channel positions as a partner of STMicroelectronics, an NXP Approved Engineering Consultant, a Linux Foundation Silver member, and a Training Partner of the Zephyr Project, with additional alliances to Percepio, BUGSENG, wolfSSL, ETSI, the ARM Connected Community, the Yocto Project, Android AOSP, FreeRTOS, and RISC-V. Customers are embedded-systems engineers, firmware developers, and (more recently) product managers responsible for EU CRA compliance, but no enterprise customer logos, ARR figures, or segment revenue splits are disclosed.

Broad incumbents

• IAR Systems: Established Swedish vendor of commercial embedded development tools (IAR Embedded Workbench) and related training. Comparable because it sells IDE tooling for the same MCU/RTOS ecosystems Ac6 trains engineers on, at significantly greater scale.
• LDRA: UK/US vendor of embedded software verification and static analysis tools with training and certification services. Comparable because it serves the same embedded-secure-coding persona Ac6 targets in its Secure Development for Embedded Systems course.
• Hitex Development Tools: German embedded development tools and engineering services firm serving automotive and industrial customers. Comparable in offering a bundled tools-plus-services play targeting embedded developers, similar to Ac6's three-entity structure.
• SEGGER Microcontroller: German provider of embedded development tools (J-Link, Embedded Studio, Ozone). Adjacent comparable in embedded tooling space, with broader product portfolio and ecosystem reach than Ac6's Workbench tools.

Emerging players

• Percepio: Swedish vendor of Tracealyzer runtime visualization tools for embedded and RTOS systems (FreeRTOS, Zephyr). Comparable as an embedded-tools peer that complements Ac6's training with trace-analysis software, and a current Ac6 partner.
• Nohau: Scandinavian embedded development tools and training provider. Comparable to Ac6 because it sells embedded IDE/debug tools and co-marketed the May 2024 Zephyr OS introduction webinar with Ac6, indicating overlapping training portfolios.
• Embedded Systems Academy: Independent embedded systems training and consultancy specializing in industrial communication protocols, CAN, and microcontroller training. Comparable to Ac6 as a small, specialized instructor-led embedded training provider.

Direct peers

• Feabhas: UK-based specialist training provider for embedded C/C++, RTOS, and modern C++ on embedded targets. Directly comparable to Ac6 as a small, niche embedded-software training company serving professional engineers with instructor-led courses.
• Doulos: Long-established independent training company covering hardware design, embedded software, and FPGA. Closely comparable to Ac6 in being a third-party instructor-led training specialist focused on embedded and electronic systems.
• Beningo Embedded Group: US-based embedded consulting and training firm specializing in firmware, RTOS, and embedded software design. Direct comparable to Ac6's ac6-conseil arm, with similar persona targeting (firmware engineers) and consulting-plus-training model.
