Promwad vs Integra Sources: overview

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.

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.

Promwad vs Integra Sources: pros and cons

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
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
