DornerWorks vs Integra Sources: 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.
Integra Sources
Integra Sources, founded in 2014, is a compact custom hardware and firmware development shop reporting 250+ completed IoT and embedded projects despite public sources disagreeing on both its exact headquarters (most list Astana, Kazakhstan) and current headcount (estimates range from roughly 24 to 51 employees). For a technical buyer, the operative pitch is turnkey delivery: electronic design, PCB layout, FPGA, embedded firmware, and kernel/driver development for Windows, Linux, macOS, and Android all sit under one small team, avoiding the vendor-coordination overhead that comes with splitting hardware and firmware across separate suppliers — a meaningful consideration for an early-stage program without in-house hardware engineering to manage that coordination itself.

DornerWorks vs Integra Sources: pros and cons
| DornerWorks | |
|---|---|
| + | FPGA and open-source Xen hypervisor work are specific, checkable specialties rather than generic embedded-software claims |
| + | Two decades of concentrated focus on aerospace, defense, and medical — domains where reliability requirements are highest and hardest to fake |
| + | US-based team simplifies export-control and ITAR-sensitive engagements for defense procurement teams |
| - | 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 |
| Integra Sources | |
|---|---|
| + | One team handles electronic design, PCB layout, FPGA, and firmware without the client having to coordinate separate hardware and software vendors |
| + | 250+ completed projects reported despite a small team size, suggesting efficient project turnover |
| + | Kernel/driver development spans four major operating systems (Windows, Linux, macOS, Android), broader OS coverage than most similarly sized boutiques |
| - | Public sources disagree on both headquarters location and headcount, making delivery capacity harder to verify precisely (per company website and third-party directories; independently unverifiable) |
| - | Small team size limits fit for programs needing multiple concurrent workstreams |
| - | No public case studies with named enterprise clients to independently verify scale claims |
