Promwad vs ARCH-Embedded: overview
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.
ARCH-Embedded
ARCH-Embedded was founded in Amsterdam in 2022 by CEO and co-founder Mark Riemersma and operates with a team of 2 to 10 people. As a Nordic Semiconductor partner, the firm's stated background is specifically in positioning technology and micro-mobility, with prior team experience at companies like TomTom, and it covers the full stack from hardware through embedded software, RTOS, Linux, security, and connected-device architecture and project management. That positioning-technology specialty is narrow but genuinely differentiated, useful specifically for clients building location-aware or cellular-connected hardware rather than general-purpose embedded products.

Promwad vs ARCH-Embedded: pros and cons
| 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 |
| ARCH-Embedded | |
|---|---|
| + | Nordic Semiconductor partner status backs its cellular and positioning-technology hardware claims |
| + | Team background in positioning technology at companies like TomTom is a specific, differentiated specialty rather than general IoT experience |
| + | Full-stack scope from hardware through RTOS, Linux, and security architecture covers more than firmware coding alone |
| + | Small team size means direct senior engineering involvement on every engagement |
| - | Founded in 2022 with 2 to 10 employees, giving it one of the shortest track records and smallest teams on this list |
| - | Capacity for large or multiple concurrent programs is limited by team size |
| - | No published pricing or minimum engagement figure |
