DornerWorks vs Promwad: overview
DornerWorks
DornerWorks was founded in 2000 in Grand Rapids, Michigan, and has grown to what the company describes as one of the larger dedicated embedded engineering firms of its type in the US (exact current headcount undisclosed, reported in the 51-200 range). Two decades of unbroken focus on aerospace, defense, and medical — domains where a generalist engineering firm's broader portfolio is a liability, not an asset, since reliability requirements are highest and hardest to fake — plus a recognized narrower specialty within that (FPGA co-design and the open-source Xen hypervisor) makes this a genuine specialist rather than a boutique-branded generalist.
Promwad
Founded in 2004 and headquartered in Essen, Germany with additional engineering centers in Latvia and Serbia, Promwad has built a 100+ engineer team around end-to-end electronics design: PCB layout, FPGA, embedded software, and coordination through contract manufacturing. At just over 100 people, Promwad is a mid-size specialist — large enough to run a hardware program through manufacturing handoff, still narrow enough in focus that embedded and electronics design is the entire business, not a division inside a larger generalist firm.

DornerWorks vs Promwad: pros and cons
| DornerWorks | |
|---|---|
| + | Two decades of concentrated aerospace/defense/medical focus, with no diversification into unrelated business lines diluting attention |
| + | FPGA and open-source Xen hypervisor work are a narrower, harder-to-fake specialty within an already-narrow domain focus |
| + | US-based team simplifies export-control and ITAR-sensitive engagements for defense procurement |
| - | Exact current headcount is not publicly disclosed, only described qualitatively as among the larger firms of its type in the US |
| - | Domain concentration in aerospace/defense/medical means less demonstrated relevance for consumer electronics manufacturing concerns |
| - | No public pricing tiers or minimum engagement figures for budget pre-qualification |
| Promwad | |
|---|---|
| + | Over 20 years combining PCB layout, FPGA design, and embedded software under one specialist agency, not a division of a larger generalist firm |
| + | 100+ engineers across German, Latvian, and Serbian centers give more capacity than the smallest boutiques while staying purely embedded/electronics-focused |
| + | Contract manufacturing coordination extends the engagement past pure development into production handoff |
| - | Mid-size team sits between boutique specialists and large engineering conglomerates — verify concurrent-program bandwidth directly for large needs |
| - | No large named enterprise case studies published to independently verify scale claims |
| - | No public pricing or minimum engagement figures |
