Sirin Software vs Cyient: 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.
Cyient
Cyient was established in 1991 in Hyderabad, India as Infotech Enterprises Ltd and rebranded to Cyient in 2014. At 15,000+ engineers, this sits at generalist-conglomerate scale, with aerospace avionics as one named specialty (strengthened by the CERTON Software acquisition) among a broader Design-Build-Maintain engineering portfolio spanning multiple unrelated verticals.

Sirin Software vs Cyient: 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 |
| 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 |
| - | Rebranded from Infotech Enterprises Ltd in 2014 — buyers researching the firm's older track record should 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 |
