Lemberg Solutions vs DornerWorks: overview
Lemberg Solutions
Lemberg Solutions is a 200+ person embedded and full-stack engineering firm founded in 2007 and headquartered in Lviv, Ukraine, with additional offices in Hamburg, Germany, London, United Kingdom, and Kraków, Poland. At 200+ people, it sits well above the smallest boutiques on this list but far below the multi-thousand-engineer generalist firms — a size where embedded is still unambiguously the firm's core business, not one line item competing for resourcing against unrelated business units, while still having enough bench depth (electrical engineering, firmware, embedded Linux, FPGA, connectivity, edge AI, cybersecurity) to staff a program with several parallel workstreams. ISO 9001/27001/13485 certification and named clients (Astronics, Caltech, Speede, Ferno, Cellink, Bosch Rexroth) back the claim with checkable references rather than scale alone.
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.

Lemberg Solutions vs DornerWorks: pros and cons
| Lemberg Solutions | |
|---|---|
| + | Large enough (200+) to staff multiple parallel workstreams without embedded competing internally against unrelated business units for resourcing |
| + | ISO 9001, ISO 27001, and ISO 13485 certifications give a specific, checkable quality signal beyond team size alone |
| + | Named clients (Astronics, Caltech, Speede, Ferno, Cellink, Bosch Rexroth) support reference-checking before committing |
| + | Full IP and source code transfer to the client on delivery, standard across every engagement |
| + | Named public case studies with specific outcomes rather than generic capability claims |
| - | Does not manufacture at scale — teams wanting one specialist agency through mass production will still need a separate manufacturing partner |
| - | Does not carry regulatory certification itself — supports documentation but the client retains ownership of the certification process |
| - | No published rate card — cost comparison against smaller boutiques or larger generalists requires a direct quote |
| 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 |
