Conclusive Engineering vs ARi: overview
Conclusive Engineering
Conclusive Engineering was founded in 2018 by Jakub Klama and Wojciech Kloska, based in Katowice, Poland, with a second office in Piaseczno near Warsaw. The team of roughly 30 engineers works across Linux, FreeBSD, RTOS, and bare-metal firmware, with particular depth in low-level debugging and hard real-time optimization for systems that cannot tolerate jitter. Because the founders came directly from kernel and driver-level engineering roles rather than management backgrounds, the firm stays hands-on with senior staff through the full engagement instead of handing projects to junior teams after scoping.
ARi
ARi traces its engineering roots to 2001 and began operating under the ARi brand in 2006, headquartered in East Peoria, Illinois, with seven additional locations across North America and Asia Pacific; the company reports more than 1,100 employees. Embedded software and firmware sit inside a much broader industrial engineering business that also covers mechanical product design, manufacturing engineering, industrial automation, and robotics, so ARi suits a client whose project spans hardware, firmware, and manufacturing rather than firmware in isolation. Its scale supports large industrial programs that a boutique firmware firm could not staff alone.

Conclusive Engineering vs ARi: pros and cons
| Conclusive Engineering | |
|---|---|
| + | Founders bring direct kernel and driver-level experience rather than a management tier sitting over junior engineers |
| + | Covers Linux, FreeBSD, and bare metal, spanning more of the real-time spectrum than Linux-only vendors |
| + | Small team size keeps senior engineers hands-on for the full engagement instead of handing off after scoping |
| - | Roughly 30 engineers caps how many large programs the firm can staff at once |
| - | Founded in 2018, so its public track record is shorter than firms operating since the 1990s or 2000s |
| ARi | |
|---|---|
| + | More than 1,100 employees and eight total locations support very large industrial programs |
| + | Embedded firmware sits alongside mechanical design and manufacturing engineering for hardware-heavy products |
| + | Long engineering history predating the current brand, formalized under the ARi name in 2006 |
| - | Firmware is a smaller specialty inside a much larger industrial automation and manufacturing business |
| - | Scale and process overhead can be more than a small firmware-only project actually needs |
