Timesys vs Promwad: overview
Timesys
Timesys was founded in Pittsburgh in 1995 and built its reputation as a founding member of the Yocto Project, one of the two dominant embedded Linux build systems alongside Buildroot. The company's LinuxLink platform and development-support services cover custom board support package creation, security patch tracking, and long-term maintenance for embedded Linux products, work that is narrower than general firmware development but goes deeper into that one area than most generalist firms can. Lynx Software Technologies, a real-time operating system and safety-critical software vendor, acquired Timesys in 2023, folding its embedded Linux practice into a broader RTOS and hypervisor product line.
Promwad
Promwad was founded in 2004 by Roman Pakholkov and is now headquartered in Essen, Germany, with roughly 146 employees across Europe, North America, and Asia. The company covers embedded software development, hardware design, PCB layout, and enclosure design, with stated ASIL-C functional-safety work in automotive infotainment and ECU development alongside telecom, digital TV, and industrial automation projects. That combination of electronics design and firmware under one roof, plus safety-relevant automotive experience, distinguishes it from firmware-only vendors that don't carry board-level design capability.

Timesys vs Promwad: pros and cons
| Timesys | |
|---|---|
| + | Founding member of the Yocto Project, one of the two standard embedded Linux build systems in the industry |
| + | Three decades of operating history focused specifically on embedded Linux rather than firmware in general |
| + | Security patch tracking and long-term maintenance services address a gap most project-based firmware vendors don't cover after delivery |
| + | Acquisition by Lynx Software Technologies in 2023 connects its Linux practice to a broader RTOS and hypervisor product line |
| - | The 2023 acquisition by Lynx Software Technologies means Timesys now operates as part of a larger RTOS vendor rather than an independent consultancy |
| - | Its specialty is embedded Linux specifically, so RTOS-only or bare-metal MCU projects are a narrower fit than for a generalist firmware vendor |
| - | Public team size and pricing figures are not published |
| Promwad | |
|---|---|
| + | ASIL-C functional-safety work in automotive ECU and infotainment development is a specific, verifiable safety credential |
| + | Electronics design, PCB layout, and firmware sit inside one company rather than being split across vendors |
| + | 21 years of operating history and roughly 146 people give it more delivery capacity than most boutique firmware teams |
| + | Industry spread across telecom, automotive, digital TV, and industrial automation reduces single-sector concentration risk |
| - | ASIL-C is one level below the ASIL D some automotive safety programs require, which may not fit the most stringent projects |
| - | 146 employees spread across telecom, automotive, and industrial work means firmware specialists are shared across a broader practice, not a dedicated firmware-only team |
| - | No published pricing or minimum engagement figure |
