Sirin Software vs Cyient: overview
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.
Cyient
Cyient was established in 1991 in Hyderabad, India as Infotech Enterprises Ltd and rebranded to Cyient in 2014 — worth knowing when researching the firm's pre-2014 track record under its original name. The company's embedded avionics work spans fly-by-wire, actuation systems, collision avoidance, and autopilot controls, strengthened by the acquisition of CERTON Software, a dedicated avionics software firm. Reported headcount sits in the 12,000-15,000+ range across a broader Design-Build-Maintain engineering services portfolio, with aerospace/avionics as a named specialty rather than the firm's only focus.

Sirin Software vs Cyient: pros and cons
| 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 |
| Cyient | |
|---|---|
| + | Named aerospace avionics specialization covering fly-by-wire, actuation, collision avoidance, and autopilot controls |
| + | Acquisition of CERTON Software added dedicated avionics software engineering depth to the practice |
| + | Rebranded from Infotech Enterprises in 2014 with over 30 years of underlying engineering services history to research under both names |
| - | Rebranded from Infotech Enterprises Ltd in 2014 — buyers researching the firm's older track record need to search under both names |
| - | Aerospace/defense weighting means less demonstrated relevance for consumer or industrial IoT embedded work |
| - | Exact current headcount and pricing figures vary by source and aren't officially disclosed |
