Sirin Software vs SYSGO: 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.
SYSGO
SYSGO, founded in 1991 and headquartered in Klein-Winternheim, Germany, is the vendor behind PikeOS, a SIL 4-certified RTOS/hypervisor. As an onshore-Germany, Thales-affiliated vendor, SYSGO's outsourcing structure is licensing-plus-services rather than pure labor-hour delivery — relevant for buyers whose safety-critical certification requirements make cost-tier outsourcing decisions secondary to platform certification and long-term vendor stability.

|---|---|
| + | US-based contracting entity simplifies invoicing and legal terms for American clients while engineering is delivered offshore at lower cost |
