Sirin Software vs Cyient: overview
Sirin Software
Sirin Software, founded in 2014, is headquartered in Pompano Beach, Florida with R&D centers in Kyiv and Ivano-Frankivsk, Ukraine — a deliberate US-front, Ukraine-delivery structure that gives American buyers a single US contracting entity while the actual engineering work happens at Ukraine's substantially lower cost base. This structure is common among boutique outsourcing firms and worth understanding explicitly: the client relationship and invoicing run through the US entity, while day-to-day engineering is offshore.
Cyient
Cyient was established in 1991 in Hyderabad, India as Infotech Enterprises Ltd and rebranded to Cyient in 2014 — a naming history outsourcing buyers should research under both names. India-based delivery at 15,000+ engineer scale gives Cyient significant offshore capacity, strengthened for avionics-specific outsourcing by the acquisition of CERTON Software, a dedicated avionics software firm.
