Integra Sources vs Promwad: overview

Integra Sources

Integra Sources, founded in 2014, is a compact custom hardware and firmware shop with public sources disagreeing on both its exact headquarters (most list Astana, Kazakhstan) and current headcount (roughly 24 to 51 employees, depending on the source). At this size, turnkey delivery — electronic design, PCB layout, FPGA, embedded firmware, and kernel/driver development for Windows, Linux, macOS, and Android — all under one small team is the actual value proposition: no coordinating separate hardware and software agencies, which matters more for a startup buyer than choosing between generalist scale options.

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.

Integra Sources vs Promwad: pros and cons

Integra Sources
+ One team handles electronic design, PCB layout, FPGA, and firmware without the client coordinating separate hardware and software agencies
+ 250+ completed projects reported despite a small team size, suggesting efficient project turnover for a boutique this size
+ 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
- Small team size limits fit for programs needing multiple concurrent workstreams
- No public case studies with named enterprise clients to independently verify scale claims
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
