Lemberg Solutions vs DornerWorks: overview
Lemberg Solutions
Lemberg Solutions is a 200+ person embedded and full-stack engineering firm founded in 2007, headquartered in Lviv, Ukraine, with additional offices in Hamburg, Germany, London, United Kingdom, and Kraków, Poland. For an RFP evaluator, the relevant service-scope detail is that Lemberg offers all three standard engagement models — technical consulting, team extension/staff augmentation, and end-to-end product development — under a single ISO 9001/ISO 27001/ISO 13485-certified quality system, spanning electrical engineering, PCB design, firmware, embedded Linux, FPGA, connectivity, edge AI, and cybersecurity. Named semiconductor partnerships (NXP, Microchip, STMicroelectronics as primary partners) and a documented in-house hardware lab back the technical claims, and named clients (Astronics, Caltech, Speede, Ferno, Cellink, Bosch Rexroth) give procurement teams checkable references. Full IP and source code transfer to the client on delivery, a standard RFP requirement this firm meets without qualification.
DornerWorks
DornerWorks was founded in 2000 in Grand Rapids, Michigan, serving aerospace, defense, medical, and industrial clients whose procurement processes typically require documented reliability engineering practices. The firm offers both fixed-project and time-and-materials engagement models and has built its practice specifically around FPGA co-design and open-source Xen hypervisor work — narrower service-scope claims than a generalist RFP respondent, but ones the firm can back with two decades of aerospace/defense delivery history. US incorporation simplifies export-control and ITAR compliance documentation, a recurring RFP requirement for defense-adjacent procurement that offshore vendors cannot satisfy as cleanly.

Lemberg Solutions vs DornerWorks: pros and cons
| Lemberg Solutions | |
|---|---|
| + | All three standard RFP engagement models (consulting, staff aug, full delivery) available under one certified vendor, simplifying multi-lot procurement |
| + | ISO 9001, ISO 27001, and ISO 13485 certifications map directly to common RFP compliance requirements for medical, security, and quality-managed programs |
| + | Named semiconductor partnerships (NXP, Microchip, STMicroelectronics) plus a documented hardware lab support technical due diligence |
| + | Full IP and source code transfer on delivery — a standard RFP requirement met without exception clauses |
| + | Named, checkable references (Astronics, Caltech, Speede, Ferno, Cellink, Bosch Rexroth) support procurement reference-checking |
| - | Does not manufacture at scale — RFPs requiring a single vendor through mass production will need a separate manufacturing partner |
| - | Does not carry regulatory certification itself — provides documentation and support, but the client retains ownership of the certification process |
| - | No published rate card or minimum engagement figure — budget qualification requires a direct RFI or discovery call before a formal RFP |
| DornerWorks | |
|---|---|
| + | Both fixed-project and time-and-materials models offered, covering the two most common RFP pricing structures |
| + | US incorporation simplifies ITAR and export-control compliance documentation for defense-adjacent procurement |
| + | Two decades of concentrated aerospace/defense/medical delivery history strengthens reference-checkable RFP responses |
| - | Exact current headcount is not publicly disclosed, only described qualitatively — RFP capacity questions will need a direct answer from the vendor |
| - | Domain concentration in aerospace/defense/medical means less demonstrated relevance for consumer-electronics-scale manufacturing RFPs |
| - | No published rate card or minimum engagement figure for budget pre-qualification |
