The overall market is already sizable and growing, driven by expanding automation, aerospace, and defense needs, increasing system complexity, and the shift toward software-defined physical systems.

Buyers already allocate meaningful budgets, and procurement cycles show that the category is considered core infrastructure.

Within that context, two groups dominate the landscape:

• Incumbents that depend on outdated architectures and slow upgrade paths, which limit their ability to respond to new interoperability and scalability requirements.
• Startups that chase specific subproblems, validating demand but also illustrating that no one has delivered a unified solution.

The market size and the fragmented competitive field create space for Oxidos to enter and address core industry problems.

Direct classic competition (OS and tools) - the current leaders include:

• Vector Informatik (MICROSAR.OS) - classic AUTOSAR based Embedded OS + tools + services. Vector uses complex legacy systems that have been patched up over time and retrofitted. They are working to retrofit and add Rust-lang support.

  OxidOS unifies OS and dev tools in one Rust-based stack, reducing reliance on Vector’s multiple specialized tools and C code.

• Elektrobit Automotive GmbH (EB tresos Safety OS) - classic AUTOSAR based Embedded OS + tools + services. They are also using old tooling and software stacks.

  Unlike Elektrobit, we are building and OS developed 100% in Rust-lang.

• APTIV - through its Wind River VxWorks solution - a proprietary real-time OS that was acquired by APTIV in 2022 for 3**.5B.** Used both in automotive and aerospace & defense. Main OS solution in aerospace & defense.

  OxidOS offers memory-safe Rust and open portability vs VxWorks’ legacy C++ monolithic RTOS architecture.

• ETAS Group / Bosch (RTA-OS) - classic AUTOSAR-based Embedded OS + tools + services.

  They are also using old tooling and software stacks, similar to the solutions from Vector.

  Unlike ETAS, we are building and OS developed 100% in Rust-lang.

• BlackBerry QNX - commercial microkernel RTOS widely used in safety-critical automotive, medical, and industrial systems.

  OxidOS’ rust-based modular OS offers better portability & faster updates vs QNX’s proprietary C/C++ microkernel design.

• eSOL - safety-certified real-time OS (eMCOS RTOS) and middleware for automotive ECUs.

OxidOS uses memory-safe Rust and an open-source base approach unlike eSOL’s RTOS that is a traditional C/C++ multikernel design.

• Green Hills - provides tooling for C/ Ada language based development & a POSIX hard real-time OS. Used both in automotive and aerospace & defense.

  OxidOS relies on Rust safety and modern tooling vs Green Hills’ closed, legacy ecosystem (proprietary C/Ada).

Start-ups that are developing products in the same space:

• ApexAI - new generation operating system, based on ROS, aimed at powerful chips and mostly ADAS / AI applications.

  Compared with Apex - our solution can run on smaller chips and adresses more used cases.

• Eatron Technologies - new generation ECUs - software + hardware - focus in BMS (Battery Management Systems)

  Compared with Eatron - our solution has a broader scope, albeit it might not be as performant and “plug and play ready” for the BMS use cases that Eatron is focused on.

• Sonatus - with a focus on middleware

  Compared with Sonatus, we are building the underlying layer.
