DornerWorks vs Promwad: overview

DornerWorks

DornerWorks was founded in 2000 in Grand Rapids, Michigan, to bring electronics engineering discipline to aerospace, defense, medical, and industrial clients where reliability isn't negotiable. Over two decades it has grown into what the company describes as one of the larger dedicated embedded engineering design firms in the US by team size, though exact current headcount isn't publicly disclosed. For a technical evaluator, the two most concrete signals are the firm's FPGA practice and its work with the open-source Xen hypervisor — both narrower, harder-to-fake specialties than generic "embedded software development," and both directly relevant to safety-critical systems needing hardware/software co-design and workload isolation. Being US-based also simplifies export-control and ITAR considerations for defense-adjacent programs, which matters more to a procurement team than to a casual buyer.

Promwad

Founded in 2004 by Roman Pakholkov and now headquartered in Essen, Germany with additional engineering centers in Latvia and Serbia, Promwad has spent over two decades building a 100+ engineer team around end-to-end electronics design: PCB layout, FPGA, embedded software (Linux and Android), and coordination through contract manufacturing. For a technical buyer weighing whether to split hardware and firmware across two vendors, Promwad's pitch is specifically that both live under one contracted engagement — reducing the interface risk between electrical design decisions and firmware behavior that trips up multi-vendor programs.

- Exact current headcount is not published — only described qualitatively as among the larger firms of its type in the US (per company website; independently unverifiable)
- Domain concentration in aerospace/defense/medical means less demonstrated experience in high-volume 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 contracted engagement, reducing hardware/firmware interface risk
+ 100+ engineers across German, Latvian, and Serbian centers gives more capacity than the smallest boutiques
+ Contract manufacturing coordination extends the engagement past pure development into production handoff
- Mid-size team sits between boutique specialists and large engineering conglomerates — verify bandwidth directly for concurrent enterprise-scale programs
- No large named enterprise case studies published to independently verify scale claims
- No public pricing or minimum engagement figures
