Promwad vs Sirin Software: 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.

Sirin Software

Sirin Software, founded in 2014 and headquartered in Pompano Beach, Florida with R&D centers in Kyiv and Ivano-Frankivsk, Ukraine, works specifically with semiconductor companies and IoT product teams on SDKs, firmware, middleware, and driver development. What makes Sirin relevant for a technical buyer comparing wireless-protocol depth specifically is the breadth of named protocol stacks it works across — Wi-Fi, BLE, Matter, UWB, NFC, and LoRaWAN — combined with embedded OS coverage spanning Linux, Zephyr, FreeRTOS, and ThreadX, rather than one protocol done well and everything else avoided.

Promwad vs Sirin Software: 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
Sirin Software
+ Works directly with semiconductor companies on SDK and driver development, closer to the chip than typical downstream product-firmware shops
+ Named coverage across six distinct wireless protocols reduces the need to shop separately for each connectivity technology
+ US headquarters with Ukraine R&D centers balances client-facing accessibility with delivery cost efficiency
- Small team (11-50, varying by source) limits capacity for programs with several parallel workstreams
- No public pricing tiers or minimum engagement figures for pre-qualification
- Multi-protocol breadth means depth in any one protocol may be shallower than a single-protocol specialist
