Sirin Software vs QuEST Global: 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.
QuEST Global
QuEST Global, founded in 1997 and headquartered in Singapore, operates over 90 delivery centers across 18+ countries — one of the broadest global outsourcing footprints on this list. Reported employee counts vary substantially by source (roughly 21,500 to over 32,000), itself a sign of a firm too large and diversified for a single precise headcount. Embedded and silicon engineering is one capability among many verticals rather than a dedicated outsourcing specialty.
