Cyient vs QuEST Global: overview
Cyient
Cyient was established in 1991 in Hyderabad, India as Infotech Enterprises Ltd and rebranded to Cyient in 2014 — a naming history procurement teams should research under both names during vendor due diligence. 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 worth citing specifically in aerospace RFP technical evaluations.
QuEST Global
QuEST Global was founded in 1997 and is headquartered in Singapore, operating over 90 delivery centers across 18+ countries serving aerospace and defense, automotive, energy, hi-tech, healthcare, rail, and semiconductors. Reported employee counts vary substantially by source (roughly 21,500 to over 32,000), which is itself worth noting in an RFP due-diligence checklist — a firm this size and this diversified doesn't lend itself to a single precise headcount figure. Embedded and silicon engineering is offered directly to chipmakers as part of end-to-end services, one capability among many verticals rather than a dedicated specialty.
