Our Core

Maximum Performance. Minimal Abstraction.

Return Infinity builds operating systems that are deliberately lean and engineered for speed and robustness. Instead of using conventional kernel designs that insert many layers between software and hardware, their systems strip away unnecessary overhead. This means applications can interact with hardware more directly than in traditional OSes, reducing delays and increasing throughput. Their primary product, called BareMetal, is a kernel focused on exposing hardware resources directly to software to enable high-performance computing tasks with strong security and minimal system overhead.

Operating systems designed for speed and security.

Return Infinity positions itself as a specialist in low-level system development, emphasizing both performance and security. By minimizing the abstractions that typical operating systems impose, they reduce the attack surface available to malicious actors. The result is an environment where resource management happens at the application level, allowing firms to tailor performance and security behavior to their specific workloads.

We've created the BareMetal exokernel.

Traditional operating systems use either monolithic kernels (where most services run in a single privileged space) or microkernels (which break up services into modular components). Both still enforce abstractions - like process schedulers, generalized file systems, and device layers - to give a uniform interface to developers.

Return Infinity’s BareMetal takes the opposite approach:

  • It is an exokernel: a minimalist kernel architecture that avoids imposing abstract management policies.

  • Rather than hiding hardware details behind generalized frameworks, BareMetal allows an application or system developer to directly manage hardware resources such as memory, disk storage, interrupts, and CPU scheduling.

  • This reduces latency and system overhead, yielding more predictable execution and performance.

  • Security is improved because the kernel only multiplexes hardware safely; the application retains control over its own resource policies.

  • The focus is on just enough operating system (JeOS) for the workload’s needs.

How BareMetal Improves Performance and Security

Security

By isolating a single application’s resources and avoiding monolithic policy layers, BareMetal reduces common attack vectors found in traditional kernels. This grants application-level control with fewer implicit assumptions and less shared state vulnerable to exploitation.

Performance

The design purposefully minimizes context switches and kernel overhead. By delegating resource decisions to the application, systems eliminate many delays that arise from general-purpose kernel scheduling and background services. This yields high responsiveness and deterministic behavior critical in time-sensitive computing.

High Frequency Trading

Markets operate at microsecond scales. BareMetal’s architecture removes scheduler delays and other background processes so financial algorithms can execute deterministically, making every microsecond count in high-frequency trading environments.

Cloud Infrastructure

In cloud and virtualization settings, typical OS overhead reduces effective workload density. By running a “Just Enough OS,” service providers can host more workloads on the same hardware and eliminate unnecessary processes that consume CPU or memory.

Embedded Systems

BareMetal’s tiny footprint and direct hardware access make it suitable for IoT gateways, real-time analytics devices, and other embedded deployments where both performance and resource efficiency are essential.
