Sirin Software vs Promwad: overview
Sirin Software
Sirin Software, founded in 2014, runs an 11-50 person team headquartered in Pompano Beach, Florida with R&D centers in Kyiv and Ivano-Frankivsk, Ukraine, specifically on SDKs, firmware, middleware, and driver development for semiconductor companies and IoT product teams. Small size here maps to genuine specialization rather than a limitation: named depth across six wireless protocols (Wi-Fi, BLE, Matter, UWB, NFC, LoRaWAN) spanning Linux, Zephyr, FreeRTOS, and ThreadX is a narrower, deeper claim than most much larger generalist firms make about connectivity work.
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.

Sirin Software vs Promwad: pros and cons
| Sirin Software | |
|---|---|
| + | Named coverage across six wireless protocols is a narrower, more specific claim than the generic 'connectivity expertise' most larger firms list |
| + | Works directly with semiconductor companies on SDK and driver development, closer to the chip than downstream product-firmware generalist work |
| + | Boutique size means the client-facing team is likely the same team doing the engineering, not separate sales and delivery layers |
| - | Small team (11-50, varying by source) limits capacity for programs needing several parallel workstreams |
| - | No public pricing tiers or minimum engagement figures for pre-qualification |
| - | Multi-protocol breadth within a small team means depth in any one protocol may be shallower than a single-protocol specialist |
| 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 |
